This page is for someone who owns an office in Singapore — a single strata unit on a high floor of a Raffles Place tower, a whole floor bought for yield, or premises a business has outgrown — and wants to sell it. It answers one question: what do I need to know before I sell an office. The short version is that office space sits in a different tax and financing universe from every residential product on this site: no ABSD on your buyer, no MOP, no SSD on your own exit, and no Land Dealings Approval Unit gate standing between a foreign buyer and your listing. In exchange, the buyer pool is thinner than residential property's, the banks underwrite more conservatively in practice than the regulatory ceiling implies, and a 2022 planning rule has quietly turned some buildings into a closed, appreciating club. I name plainly, in the closing section, where a government page did not render to direct fetch and a figure rests on a secondary source instead.

In house order: the mechanics of what you are actually selling; who may own and buy; what citizenship status changes, which for this product is mostly a settled question; taxes, where the real divergence from residential property lives; borrowing; the control you actually have over the asset, in place of the addition-and-alteration playbook a landed page would run; conveyancing; estate; the twelve-question frame; the professional door for the businesses that serve this deal; and what a realtor actually earns selling it. Worked examples use a hypothetical S$3,000,000 strata office unit, labelled as such throughout, not a market quote.

The mechanics: what you're actually selling, and why the stock is closing

Most office space in Singapore is never sold unit by unit — a REIT or an institutional landlord holds the whole tower and lets floors to tenants, and that building never appears as a listing you can buy. What can be bought and sold, and what this page is written for, is strata-titled office space: individual units or floors carved out of a building, each owner holding a share of common property through an MCST, the same shape as a strata retail unit or a condominium, built for tenants rather than residents. A market guide splits this stock into three tiers: Grade A core-CBD floors (Suntec City's towers are the benchmark) at roughly S$2,800-3,500 psf with 3.5-4.5% gross yield; Grade B fringe-CBD stock (International Plaza is cited) at S$1,800-2,500 psf with 4.5-5.5% yield; and Grade C older, decentralised stock at S$1,200-1,700 psf with 5.5-7.0% yield — a higher headline yield compensating for vacancy risk, tenure decay and a thinner buyer pool when it is your turn to sell, not a free lunch.

A reported September 2025 Suntec City transaction gives a sense of the top end: three strata units on a high floor combined into a 10,097 sq ft floor, marketed via expression of interest at S$34.83 million (S$3,450 psf combined), individual unit prices from S$8.53 million to S$16.92 million, fully tenanted and reported capable of gross yields up to 3.8%. That expression-of-interest format — competing bids solicited from a small, qualified pool rather than an open listing — is common at this end of the market and is itself a signal of how thin the genuine buyer pool is for a large commercial lot.

Why the stock keeps getting harder to add to: URA's Circular DC22-02, effective 15 March 2022, bars strata subdivision of the commercial component of new developments — the circular names office, shop and restaurant uses explicitly — across the Orchard Road corridor, the CBD corridor along Shenton Way, Robinson Road, Anson Road, Raffles Quay and the Singapore River, and sites near landmarks such as Parliament House and the Padang. A building already strata-subdivided, or with an application in before that date, keeps its subdivision; the restriction bites only future redevelopment. In practice, URA does not intend to let developers build more Suntec-style strata office in the precincts where it is worth most, which is the structural reason existing stock in those precincts prices at a premium — and, for you as a seller, the reason your comparable-unit buyer pool is not about to be diluted by new competing supply.

On the wider, non-strata market: URA's Q2 2026 statistics show the office price index up 0.4% quarter on quarter (against +0.2% in Q1), the rental index up 0.8% (against -0.2% in Q1), and island-wide vacancy at 11.0%, up from 10.8% — a market firming on price and rent even as vacancy ticks up, worth putting in front of a buyer rather than quoting one figure and letting it imply the other. Core CBD Grade A vacancy sat at a record-low 3.3% in the same quarter, still landlord-favourable for prime space, while about 848,000 sq m GFA remained in the development pipeline, down from 867,000 sq m the quarter before.

The conveyancing shape tracks an ordinary private resale: an Option to Purchase, an exercise fee, a bank valuer drawn from the buyer's own panel who pulls comparable transactions and adjusts for floor, facing and remaining lease, and cash-over-valuation if your price outruns what that valuer supports. CEA's own consumer-facing 'renting or renting out' and 'buying or selling private property' guidance is written for residential transactions only — the templates, checklists and commission conventions it publishes name only HDB and private residential property, not commercial or industrial. A commercial deal still needs a CEA-registered agent working through a licensed agency (licensing has covered residential, commercial and industrial property alike since 1 January 2011), but you are negotiating the actual paperwork against market convention, not a CEA-prescribed template.

Eligibility: who may own and sell, and who may buy without asking anyone

There is no minimum holding period to clear before you can sell an office, the way there is a five-year MOP on an HDB flat, and no SSD clock running against an early exit either (more on that below). The eligibility question that actually matters here sits on the buyer's side, and it resolves fast: SLA's foreign-ownership list states that a foreign person may buy 'industrial and commercial properties' without approval — the same no-approval category as an ordinary condominium unit. Office space is a commercial use, so a foreign individual, company or trust can buy your unit without ever clearing the Land Dealings Approval Unit process that a foreigner buying landed housing, vacant residential land, or even a serviced apartment must go through. This is the single biggest structural difference between marketing an office and marketing almost anything residential on this site: there, foreign-buyer approval is a real bottleneck; here, it does not exist, and your buyer pool is not artificially narrowed by it.

URA also gates what the unit can be used for, on both sides of a sale. An office is a defined Business use — premises for administrative work, URA's own examples running from banks and finance offices to real estate and advertising agencies — and that use cannot simply migrate: putting an office into an industrial building or a Business Park unit is not permitted at all, and converting a unit's approved use (a retail-zoned strata unit into an office, say) needs a URA change-of-use application, an owner's consent letter, and clearance from agencies such as SCDF, LTA and NEA as applicable, reported at S$500 and about 10 working days, longer with multiple agencies. Operating on an unapproved use before written approval breaches the Planning Act, with fines reported up to S$200,000 plus daily penalties — worth confirming for both your own unit and, if a buyer's stated intended use differs from what you've been using it for, for theirs, before you exchange contracts on the strength of an assumed use.

Citizenship status: mostly a settled question here

For residential property, citizenship status is the single biggest lever this site tracks — it sets the ABSD rate, from 0% for a Singapore Citizen's first home to 65% for a trust, and it decides whether US, Swiss, Liechtenstein, Norwegian or Icelandic nationals are treated as citizens under FTA parity. Almost none of that machinery reaches an office. Because ABSD, like SSD, is a residential-property duty and an office is not residential property, a Singapore Citizen, a PR, a foreigner, a company and a trust all pay exactly the same duty on the same office purchase: non-residential BSD, and nothing layered on top for citizenship or entity type.

What citizenship status still moves, at the margin, is financing terms rather than tax: a commercial guide reports local banks underwriting strata office purchases at 60-70% LTV, tighter again at around 50-60% for a foreign buyer, since CPF cannot fund any part of a commercial purchase for anyone regardless of citizenship. It is not an eligibility gate for you as a seller — a foreign buyer needs no government approval to sign — it is a financing-speed question for how quickly that buyer's bank clears their loan, which affects how fast they can complete, not whether they may buy at all.

Taxes: BSD without ABSD, no SSD, a flat property tax, and GST at the edges

On the way in: non-residential BSD, and the ABSD every buyer skips

Non-residential BSD runs the same first four bands as residential BSD — 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000, 4% on the next S$500,000 — then a flat 5% on everything above S$1.5 million, with no further step-up the way residential BSD adds a 5%-then-6% top structure above S$3 million. On the hypothetical S$3,000,000 unit that is S$119,600, identical to the residential figure at this exact price point; the real divergence is the duty that simply is not there. A Singapore Citizen buying the same-priced property as a second residential home would owe S$600,000 in ABSD at 20%; a foreigner, S$1,800,000 at 60%; an entity, S$1,950,000 at 65%. None of it is owed on an office, by any buyer type — the number that removes any reason to structure a purchase through a company purely to dodge the entity ABSD rate, because there is nothing here to dodge.

On the way out: no SSD, and gains untaxed unless you're trading

Seller's Stamp Duty does not apply to a pure commercial property — an office, a retail shop, a mall strata unit — however soon after purchase you sell. SSD reaches residential property on a four-year schedule and industrial property on a separate three-year one; office space sits in neither, so no SSD clock runs against you at all, whether you sell in month three or year thirty. Gains on sale are not separately taxed unless you are in the business of trading property — buying and selling repeatedly for profit, judged on the pattern of dealings rather than any single transaction — a general IRAS rule, not office-specific, but the other half of why a fast, profitable exit here costs so little in tax relative to residential property.

While you hold it: a flat 10% property tax, no owner-occupier concession

Non-residential property — offices, shops, factories, warehouses — is taxed at a flat 10% of Annual Value, not the progressive owner-occupier or non-owner-occupier residential bands, and with no owner-occupier concession even where the company that owns the unit is the one occupying it, and no relief for a vacant period either. On a hypothetical Annual Value of S$150,000 (illustrative arithmetic, not a valuation), that is S$15,000 a year for as long as you hold it.

Rental income while you hold it, and GST on the way out

Rental income from letting the unit is assessed year by year on actual deductible expenses — mortgage interest, property tax, MCST fees — held for at least five years' record, rather than the 15%-deemed-expense shortcut that applies only to a tenanted residential property. If the unit sits inside a company, that income is taxed at the flat 17% corporate rate, with property tax on the investment property deductible against the rental income it generates. The wrinkle specific to selling is GST: registration is compulsory once your taxable turnover crosses S$1 million, assessed retrospectively or prospectively, and whether a specific office is held as a capital investment asset or as trading stock changes whether the sale itself counts toward that line — guides disagree at the edges, and IRAS's own GST-registration and real-estate pages both rendered navigation only to direct fetch this run, so confirm your own position with your accountant before you price the deal, not after a buyer's lawyer raises it at completion. Separately, IRAS's transfer-of-a-business-as-a-going-concern treatment — read here from its general form via a hotel example already on this ledger, not an office-specific ruling — can exclude a sale from GST entirely where the office is sold together with an ongoing operating or leasing business the buyer will continue running, rather than as a bare asset; confirm this with a tax adviser before assuming it applies to your structure.

Borrowing: a regulatory ceiling the banks don't actually use

HDB loans, MSR and the CPF Housing Scheme never touch an office; those are residential-only instruments regardless of who is buying. TDSR does apply, but only to an individual borrower — MAS's own TDSR framework exempts a company or other non-individual entity entirely, which is a real part of why so many commercial purchases are structured through one. An individual borrower faces the ordinary 55% TDSR ceiling, but stress-tested against a non-residential interest-rate floor of 5%, a full point above the 4% floor used on a residential loan — which by itself makes the same loan quantum harder to qualify for on an office than on a comparably priced condo, before a bank's own risk appetite even enters the picture.

LTV is where regulation and practice diverge hardest. MAS Notice 645 caps commercial lending at 80%; broader commercial-lending guides report banks financing 70-90% of value generally. But strata office specifically is reported financed more conservatively: 60-70% LTV in practice, tightening to about 50% for a Grade C building or a unit with under 35 years of lease remaining — a gap between the regulatory ceiling and what a bank will actually offer against your specific building that matters for how much cash your buyer needs to find, and therefore for how you price and time the sale. A worked example on a S$2,000,000 Grade B unit: 70% LTV needs S$600,000 equity plus roughly S$54,600 BSD and S$4,000-7,000 legal and valuation cost, for total cash near S$660,000; at the 60% LTV more typical of Grade C, cash required rises past S$860,000. Tenure caps at 25-30 years or the remaining lease less 5 years, pricing runs 100-150 basis points above an equivalent residential rate, and CPF cannot fund any part of a purchase or its instalments — the whole gap above whatever the bank lends is cash, for every buyer, citizen or not.

If you are the one still carrying a mortgage on the unit being sold, note that MAS's own bridging-loan definition — the exempted, no-TDSR credit facility repayable within six months — is written for a residential property purchase. There is no equivalent regulatory carve-out for a seller trading one office for another; a commercial bridge, where a bank will even offer one, runs on ordinary commercial terms rather than the residential bridging product's protections, which is a cash-flow gap worth planning for rather than assuming away if your own next move depends on this sale completing on schedule.

Control: no A&A regime for an office — fit-out, the MCST, redevelopment, and the collective sale instead

The addition-and-alteration and rebuild playbook that runs through this site's landed pages does not apply to an office at all — there is no land parcel under a strata unit and no roof to raise. What you control, inside your own unit's boundary, is fit-out. 2026 market guides put a basic refit (paint, carpet, light partitions) at S$60-100 psf over 4-6 weeks, a standard fit-out (meeting rooms, M&E, finishes) at S$100-180 psf over 8-12 weeks, a premium CBD Grade A fit-out at S$180-280 psf over 12-16 weeks, and a headquarters-grade fit-out at S$280-450 psf over 16-24 weeks, plus a further 10-15% for design, permits and project management — figures that sit inside, though not identical to, Cushman & Wakefield's own US-dollar-denominated tiers, which the ledger has not yet reconciled against the SGD contractor estimates. Reinstatement — restoring the space to its original condition — runs a further S$10-30 psf, or S$30,000-90,000 on a 3,000 sq ft unit; whichever side of that obligation you sit on when you sell (owner or outgoing tenant) is worth settling in writing before marketing starts, because a half-reinstated unit shows differently to a buyer than a freshly refitted one.

Beyond your own unit's boundary, you are a price-taker: the MCST governs the facade, shared risers and the lift lobby, and a commercial MCST — unit owners who are investors first and only ever meet the space through a tenant — is, on this site's reading, plausibly a harder body to reach consensus with than a residential one, though no figure exists to size how much harder. Capital expenditure for lift, chiller and M&E upgrades on an ageing building is reported at S$80-150 psf over a 10-year horizon, an obligation the MCST imposes on every unit owner regardless of whether their own unit needs the work — read the MCST's minutes and sinking-fund position before you set an asking price, not after a buyer's due diligence surfaces a capex vote you didn't disclose.

The one real redevelopment lever an office owner has is structural, not unit-level: URA's CBD Incentive Scheme (updated as 'CBDI 2.0' in 2025) offers a 25-30% Gross Floor Area bonus to redevelop an office building at least 20 years old, on a 1,000-2,000 sq m site, in parts of the Anson, Cecil Street, Robinson Road, Shenton Way or Tanjong Pagar precincts, into a mixed-use scheme — but the scheme is reported to require the building not be strata-subdivided, meaning a strata-titled Grade C block cannot apply directly; it would first need a collective sale to consolidate ownership, the same route a strata home takes toward redevelopment. A claim that near-term en-bloc prospects add 15-25% to a Grade C unit's valuation is a claim about that collective-sale route specifically, and this ledger has not seen the 15-25% figure itself corroborated on a government page. The general 80% consent threshold by share value and by owner count applies to a strata development regardless of use, so a strata office building can in principle go en bloc the same way a residential one does; whether the Land Titles (Strata) Act's newer, lower consent thresholds for older buildings extend to a purely commercial strata title is not something this ledger has confirmed, and a lawyer should settle that for your specific building before anyone relies on it.

Conveyancing: the legal step

There is no government fee schedule for private conveyancing; law firms quote their own rates, with market guides reporting S$2,000-5,000 all-in for a private transaction including the mortgage side. With a mortgage, allow roughly 10-12 weeks from signing the option to completion, similar to a condo rather than HDB's shorter timeline. What is absent from the paper trail, against a residential file, is any ABSD declaration, because there is no ABSD to declare; what is added is confirming the buyer's own GST registration status where you are GST-registered yourself, and — for a strata unit — pulling the MCST's minutes and sinking-fund position early enough that a capex surprise does not surface for the first time at the buyer's due diligence stage. Vacant possession, where the sale is not subject to an existing tenancy, is delivered at legal completion the same way it is on any resale.

Estate: what happens to an office when the owner dies

General estate rules apply, and — unlike almost every residential product on this site — nothing about an office adds a citizenship-driven complication on top of them. There is no estate duty in Singapore at any size (abolished for deaths from 15 February 2008); no stamp duty on a transfer to a beneficiary by way of assent; CPF savings sit outside the estate entirely, passing by CPF nomination or, with none, via the Public Trustee under intestacy rules, rather than the will — though CPF was never usable to buy the office in the first place, so there is no CPF-refund mechanic to work through here the way there is on a residential purchase. A grant of probate or letters of administration is needed before the estate can sell or transfer the unit; held in joint tenancy, it passes automatically to the surviving owner outside the will. A co-heir buying out the others to become sole owner may be treated as a sale, not an inheritance transfer, and can attract stamp duty — worth confirming with a lawyer before assuming a family buyout is duty-free.

The foreign-heir complication that reaches inherited landed housing does not reach an office at all. The Residential Property Act restricts a foreign beneficiary's inheritance of restricted residential property; an office is not residential property under the Act, the same reason a foreign buyer needs no SLA approval to buy one directly. A foreign spouse or child can inherit an office cleanly, with none of the disposal-period mechanics that follow inherited landed housing. Where the office sits inside a company rather than in the deceased's own name — common for an owner-occupier business, and for the ACD-planning reasons in the B2B section below — what passes through the estate is the shares, not the property itself, and the company continues to hold title exactly as before; that distinction is worth having a lawyer confirm early, because it changes who needs to apply for a grant, and of what.

The twelve questions, in plain words

The same frame runs on every page this site publishes, applied here to an asset that is, for almost every owner, a business tool or a yield instrument rather than a home.

Two questions that sort you

Question one: are you borrowing to buy? On an office this decides whether TDSR and the harder non-residential rate floor bind you at all, or whether, buying through a company, neither does. Question two: once you hold it, are you lending it out? Most office owners answer some version of yes — either you let it to a tenant for yield, or your own business occupies it and pays for the space through opportunity cost whether or not cash changes hands. A true owner-occupier office, held outright by the business that uses it, is the closest this product gets to the pure cash, own-use quadrant — no carry, appreciation only, and rare among strata sellers precisely because most strata office buyers are investors, not occupiers.

C0. The play

For a letting investor this is a spread play by construction — rent minus financing cost, and the gap is the whole game, sharpened here because the practical LTV ceiling sits below what the regulation allows, so more of the purchase is funded in cash than the headline 80% suggests. For an owner-occupier business it is closer to a balance-sheet play: converting a recurring lease expense into an owned asset, with appreciation or depreciation a secondary consideration to the accommodation itself.

C1. Balance sheet

What you own is a strata unit and a share of the MCST's common property, plus — if a collective sale is ever mounted around you — an obligation the collective-sale regime imposes on every owner regardless of individual vote. What you owe is the loan against it. At sale, both leave the balance sheet together, and so should any voted-but-unpaid MCST major-works levy — settle it before completion, not after.

C2. Cash flow

Separate from the balance sheet and from profit. Rent, if let, arrives on a commercial lease's own negotiated schedule — no rent-control floor the way there sometimes is on residential tenancies; the mortgage, property tax and MCST fee fall due regardless of occupancy. At sale, option money arrives early and the balance at completion roughly 10-12 weeks later; BSD is due in cash within 14 days of exercising the option — and, the one place this product's cash-flow gap is smaller than a comparable condo's, there is no ABSD to fund alongside it.

C3. Profit and loss

Profit is price less what you paid less selling costs, and it is not taxed unless you are trading — with no SSD to erode an early exit, a genuine structural difference from residential property. Rental income is taxed year by year as earned, on actual deductible expenses, entirely separately from the capital gain realised only on eventual sale — the C1/C2/C3 distinction this site insists on, because conflating them is exactly what turns a cash-flow-positive letting into a liquidity squeeze nobody saw coming.

C4. Carry

Income minus financing cost. Because the non-residential stress-test floor sits a point above the residential one, and because practical LTV runs below the regulatory ceiling, carry on a debt-funded office starts from a harder position than an equivalent condo before a single tenant is even found — exactly why so much of this market is cash-heavy or company-funded rather than leveraged the way residential property often is.

C5. Give and get

You give up a yield-bearing or self-occupied business asset in a market with fewer comparable buyers than residential property and harsher practical financing than the regulation implies. You get a buyer who owes no ABSD, a clean exit with no SSD however soon you sell, and no citizenship gate between your listing and a foreign buyer — liquidity traded for tax and eligibility simplicity, the same shape of trade this site keeps finding on every non-residential product.

C6. Exposed to

What can move against you: island-wide office vacancy at 11.0% and rising even as rents rose the same quarter; a tenant's own business failing or downsizing, sharper than a residential tenant simply moving out because commercial leases run longer and a mid-lease vacancy is a bigger single hole in cash flow; MCST decisions you did not vote for; and, for a shortening lease, the tenure-decay effect on financeability that starts biting once the remaining term drops toward 35 years and then 30.

C7. For how long

From option to cash in hand is roughly 10-12 weeks in the ordinary case. There is no SSD holding-period clock forcing a minimum four years, and no MOP forcing a minimum five, so your horizon is set by your own financing terms, your tenant's lease, and your own plans — not by a tax-code deadline the way it is on almost every residential product on this site.

C8. Failure cascade

If a tenant leaves, rent falls or stops first; that hits cash flow directly, because the mortgage, property tax and MCST fee keep falling due regardless of occupancy. Sustained vacancy accumulates into profit and loss as interest cost without offsetting income. If a sale is then needed into a thin buyer pool — the market's own description of the lower grades — price has to give, turning an intended profit into a realised loss. Illiquidity, not a fast slide to negative equity, is the dominant risk here: there is no ABSD-fuelled forced-sale dynamic the way cooling measures sometimes create on residential property; the risk is simply that it takes longer, and costs more in carrying expense, to find the buyer at all.

C9. Liquidity

Slower than a condo, and slower again the further down the grade tiers you sit: Grade A strata offices trade actively enough that transaction examples like the Suntec floor exist to cite; Grade C stock is explicitly flagged as carrying the thinnest exit market of the three tiers, with capital tied up in redevelopment-minded family offices rather than ordinary buyers. No sourced days-on-market figure exists for office specifically, and none is invented here.

C10. Control

Inside your unit you control fit-out. Outside it you are a price-taker on almost everything: the MCST governs common property and the building's condition, market rent and vacancy govern your income if you let, and a collective sale, if one is ever mounted around you, is a decision the required majority makes, not one you make alone — CBDI 2.0's redevelopment bonus is available to the building, not to an individual strata owner, unless enough neighbours first agree to sell the whole site. This is a narrower control position than landed property, where addition, alteration and rebuild give an owner real levers, and roughly comparable to what a strata retail owner has: control over the box, not over the building.

C11. The exit

Selling is the exit, and on the tax side it is about as clean as this site has anywhere: no SSD however soon you sell, no ABSD for your buyer to find in cash, only ordinary non-residential BSD, agent commission, legal fees, and — if you are GST-registered and the sale counts as a taxable supply rather than a going-concern transfer — 9% GST to account for, the one line item on this list genuinely capable of surprising a seller who has not checked their own registration status before pricing the deal. What is not cheap is time and buyer-sourcing: budget for a longer, more targeted marketing process than a comparable-value condo would need, and price against the practical LTV a buyer's bank will actually offer, not the 80% regulatory ceiling.

For the businesses that serve an office seller

This section is for the conveyancing practices, commercial mortgage advisers and agencies with a commercial desk who work an office sale. The seller's real bottleneck is rarely price discovery — URA and the portals publish enough psf and yield data for that — it is finding the specific bank that will actually lend at a workable LTV against this building's grade and remaining lease, and finding the specific buyer (company, fund, owner-occupier business) qualified and motivated to move at commercial-deal speed. Four concrete hooks worth building a practice around: a bank shortlist keyed to the practical LTV this building's grade and lease will clear, not the 80% regulatory ceiling; an MCST due-diligence pack — minutes, sinking fund, any voted-but-unpaid major works — assembled before the first viewing rather than surfaced at the buyer's lawyer's request; a clear, written answer on the sale's GST and going-concern treatment before the price is quoted, not after; and, where the seller holds the office through a company, an early read on whether that entity's asset mix keeps a later share sale outside Additional Conveyance Duty's residential-asset test — the difference between an ordinary ~0.2% share-transfer duty and a duty that can run to 71% for the buyer or 16% for the seller if the entity's assets tip residential.

The ACD point deserves its own paragraph because it is the single largest structuring lever this page has to offer, and this site has not seen it stated for office specifically anywhere it looked this run — it is reasoning by analogy from how the ledger already treats a fully commercial shophouse SPV, not an office-specific ruling, and should be confirmed with a tax adviser before anyone prices a deal around it. ACD targets a property-holding entity: broadly, one with at least 50% of its tangible assets in prescribed Singapore residential property and a significant owner holding 50% or more of its equity, with the buyer-side duty (ACDB) running up to 71% and the seller-side duty (ACDS) up to 16% where the equity is disposed of within the SSD holding period. A special-purpose vehicle whose sole asset is a fully commercial shophouse is reported to sit outside that threshold because the test is read as keyed to residential asset value, not commercial; a later sale of 100% of its shares is then taxed as an ordinary share transfer at about 0.2% duty instead. The same asset-composition logic should extend to a company holding nothing but an office — commercial-property SPVs are described generally, not just for shophouses, as falling outside ACD's residential test — which makes a share sale, rather than a direct asset sale, worth modelling for any seller who holds the office through a company for other reasons already (see estate, above).

Some points about the rules that bind you regardless of which side of this you sit on. An agent needs a Prescribed Estate Agency Agreement before starting work, is paid through the agency and not personally, and may not collect commission from both sides of the same transaction. CEA prescribes no commission rate for a commercial deal any more than a residential one; the figure is negotiated, and a firm quoting a residential-style 2% without adjusting for a commercial deal's longer marketing timeline and thinner buyer pool is mispricing its own time, not doing the seller a favour. A lender who quotes a headline 80% LTV on a strata office without checking whether its own book actually supports that on this building's grade and lease is setting an expectation the buyer will discover late — a common way a commercial deal stalls between option and completion, on this site's reading of how the pieces fit together, not from a sourced case.

If you want to work with me on this, the entry point is /work-with-me. I do not accept payment for placement on this page.

The realtor economics: what the agent earns here, and where the incentive points

CEA sets no fixed commission rate on any property type, commercial included, so an office commission is whatever you and the agent agree, documented in the same Prescribed Estate Agency Agreement that governs a residential listing. Market guides read alongside CEA's own no-fixed-rate rule report commercial sale commissions of roughly 2% to 6%, against the residential norm of a seller-paid 2%, with the buyer's agent compensated by co-broke from that or directly by the buyer where agreed, and never by both sides of the same deal — a wider range reflecting the larger due-diligence and marketing workload of a commercial sale, and one this site has not found a single authoritative office-specific figure inside, so it is not invented here. On a hypothetical S$3,000,000 sale, a 2% commission is S$60,000; at 5%, it is S$150,000. Median annual income for a Singapore agent is reported around S$72,000, and S$10,000-40,000 for a new agent in their first year — a career-site figure, not a regulator's, and one commission on a single office deal can dwarf on its own.

Where the incentive points, including against my own trade. An agent who also runs the building's leasing mandates earns a recurring commission — roughly half a month's rent on a lease of 12 months or less, about a month's rent up to 24 months — every time a tenant turns over, which is a steadier income than a single sale commission paid once, years apart, on a thinly-traded Grade C unit. That can quietly tilt an agent's advice toward keeping you as a landlord (more leasing mandates, more repeat fee events) rather than helping you sell at the best achievable price, and it is worth asking directly which outcome pays the agent in front of you more before you take their advice on whether to sell or hold. Separately, a market with a thinner, slower-moving buyer pool than residential property rewards an agent who can source the small number of genuinely qualified buyers over one who lists broadly and waits — and a price cut of S$100,000 on the hypothetical unit costs you S$100,000 and a 2% agent S$2,000, the same incentive gap that exists on every listing this site covers.

What to do about it. Ask the agent, before you sign, how many strata or commercial office deals they have actually closed, and whether they can name the two or three banks currently underwriting this building's grade and lease at a workable LTV, rather than making you find that out later. Ask for the MCST due-diligence pack up front. Ask plainly whether they also hold the building's leasing mandate, and if so, how that is priced against helping you sell. And set the exclusive period with this market's real liquidity in mind, not a condo's: a short exclusive on a niche, thinly-traded asset can mean the right buyer never hears about it at all.

What I could not verify this run

• IRAS's own pages — property tax rates, GST registration and real-estate GST guidance, and the Seller's Stamp Duty for Industrial Property page used for the commercial-exempt reasoning — all rendered navigation only to direct fetch this run; several figures above rest on secondary sources reproducing IRAS's own rules, not on the primary pages themselves.
• Whether the Land Titles (Strata) Act's newer, lower collective-sale consent thresholds for older buildings extend to a purely commercial strata title, as distinct from private residential development, is not confirmed here; the general 80% threshold is the one to rely on until a lawyer confirms otherwise for a specific building.
• Whether a specific office sale counts toward the S$1 million GST-registration threshold as ordinary turnover or a capital-asset disposal is disputed at the edges among the guides read this run and not resolved against a primary IRAS source.
• The Additional Conveyance Duty point for an office-holding SPV is reasoning by analogy from how the ledger treats a fully commercial shophouse SPV; it is not an office-specific ruling and has not been independently confirmed.
• No authoritative, office-specific commercial agent commission figure was found, only the general commercial 2-6% range and the residential 1-2% norm either side of it; no days-on-market figure for strata office specifically was found either.
• Worked examples use a hypothetical S$3,000,000 unit and a hypothetical S$150,000 Annual Value — arithmetic on the ledger's rates, not a market valuation.
