Financing the works: how to pay for a renovation after you complete

You have bought, or are about to complete on, a home that needs work. The purchase was financed by a mortgage, probably with CPF in it. The renovation is a different bill, it arrives at a different time, and almost none of the purchase financing can pay it. This page sets out what can pay for works, what each route costs, what it does to your ability to borrow, and where people run out of cash. It is written for a buyer renovating after completion: an HDB resale flat, a condominium, or a landed house that needs anything from a new kitchen to a rebuild.

What I read this run and what I am carrying from earlier reads are kept apart. Read this run: MAS on loan-to-value limits (last updated 27 March 2024), MAS on the Mortgage Servicing Ratio and Total Debt Servicing Ratio (last updated 16 December 2021), and the CPF Board page on using CPF for housing (last updated 6 July 2026). My attempts at HDB renovation, URA landed A&A and BCA pages returned errors this run. Cost figures, loan rates and fees come from commercial guides recorded in the ledger, and I did not reopen them. The closing section lists what I could not verify.

The mechanics: two bills, and only one of them has a mortgage behind it

A purchase has a financing stack built for it: a housing loan capped by loan-to-value, CPF Ordinary Account savings, and cash for whatever the first two do not cover. A renovation has none of that. The CPF Board housing page, read this run, lists what Ordinary Account savings may be used for: buying an HDB flat or private residential property or building a house, the downpayment, housing loan repayment, stamp and legal fees, a loan for the construction of a house and the purchase of vacant land, and Home Protection Scheme premiums for HDB flats. Renovation is not in that list. The ledger records the rule directly: CPF savings cannot be used for renovation, improvement or repair work. HDB likewise lends for the flat and not for what you do to it; the HDB loan is a housing loan only.

So the works are paid in cash, or in debt that is separate from the mortgage, or in debt secured on a property you already own. That gives five routes, and the rest of the page is about choosing between them.

• Your own cash. No interest, but it is the same cash you need for the option fee, downpayment, stamp duty, legal fees and moving costs, and it is the buffer for everything that goes wrong.
• A bank renovation loan. Small, quick, unsecured, and expensive once you read the effective rate rather than the headline.
• A cash-out against a property you already own: a mortgage equity withdrawal loan or a cash-out refinancing. Cheap per dollar, slow, and available only on private property.
• A construction loan, where you are rebuilding on land you own. Drawn in stages against progress, priced and capped differently from a completed-home loan.
• Bridging or short-term credit, which is for timing gaps and not for renovation, and which lenders restrict accordingly.

Timing is the second mechanic. The bank finances the purchase on the lower of price and valuation, and any shortfall between a high price and a low valuation is cash. The renovation comes on top of that, after you hold the keys. From the day you complete you owe the mortgage instalments and property tax, and you usually cannot live in the home while walls are being hacked. One law-firm guide reports S$3,000 to S$5,000 a month for temporary housing between one home and the next; that range is from an upgrading context and the ledger records it as a single reported range, so treat it as a marker and not a quote. The mortgage and the rent overlap, which is where the funding gap in C2 below actually sits.

The third mechanic is that what the money buys is not what the bank will value. Valuers value landed property as land first and depreciate the building, and one mortgage adviser's page dated 10 August 2026 describes recent structural work not being reflected in a valuation. A renovation is therefore mostly consumption from the balance sheet's point of view: you spend cash, you get a better home to live in, and the number a bank writes down does not rise by what you spent. That is the reason renovation funding should be planned as a cost, not as an investment that pays back.

Eligibility: who can use which route

Each route has a different gatekeeper. Your own cash has none. The bank renovation loan is gated by income and credit. The cash-out is gated by what you already own, how much you have paid down, and how much CPF is inside the property. The construction loan is gated by the land and the plans. HDB adds a separate gate on the works themselves, and URA and BCA add gates on landed works.

Bank renovation loans

Reported terms are a cap of S$30,000 or six times monthly income, whichever is lower, so an applicant earning S$4,000 a month is capped at S$24,000 by the multiple. A search-result summary of a comparison site quotes DBS and OCBC at 4.18% flat. I have not read the lenders' own pages this run, so treat the number as a marker of the range and not as today's price. Ask the bank for the effective interest rate, in writing, before you accept anything quoted as flat.

Cash-out against an existing property

A mortgage equity withdrawal loan (MWL) lends against equity in a property you already own. Three constraints decide who qualifies. First, it is a private-property product: MWLs cannot be taken on HDB flats, or on executive condominiums that are still in their minimum occupation period. Second, the ceiling is roughly valuation times 75% less the outstanding loan and less the CPF you have used with accrued interest, because you can only cash out against equity built with your own cash. Third, the instalments must be paid in cash, since CPF cannot be used to service an MWL. Guides disagree on how long it takes (two to four months in one, two to four and a half in another), and they disagree on whether the proceeds may fund another residential purchase; for a renovation of your own home I did not find a dispute, but confirm the permitted purpose with the bank.

The gates on the works themselves

For an HDB flat, the ledger records that owners must use contractors from HDB's Directory of Renovation Contractors, that the contractor applies for the permit, that demolition and hacking of walls, partial or complete, needs HDB's approval, and that HDB fines owners who skip these steps. I could not open the HDB page this run, so these are ledger-carried. For a condominium, the management corporation usually takes a refundable renovation deposit; two guides put it at S$500 to S$1,000 and S$2,000 to S$5,000, a spread wide enough that you should ask your own MCST. For a landed house, insignificant building works need no BCA plan submission but the owner still carries duties, and building works need approved plans by a Qualified Person; structural works need a permit applied for jointly. URA decides whether a proposal is an addition and alteration or a reconstruction, and that distinction changes the financing (see the rebuild section).

Citizenship status: it decides the purchase, not the renovation, and that is a trap

The rules that change with your status are mostly rules about buying: ABSD, CPF, HDB ownership, land approval. The renovation is financed the same way whoever you are, with one large exception, which is CPF. Because CPF cannot pay for renovation, the buyer who used CPF for the whole downpayment and instalments has a cash problem that the buyer with a large cash balance does not. Your status shows up in four places.

• Singapore Citizen. Can hold HDB and private property, uses CPF on the purchase but not on the works, and pays ABSD of 0% on a first residential property, 20% on a second and 30% on a third. The renovation sits on top of whichever of those you paid.
• Singapore PR. Pays 5% on a first residential property, 30% on a second and 35% on a third. CPF is available to PRs, so the same rule applies: works are paid in cash or separate debt.
• Foreigner. Pays 60% ABSD. CPF is not available, so the entire downpayment is cash; banks typically offer lower LTV in practice (about 60% to 70% in one guide) and they discount foreign-currency and variable income before applying TDSR, which shrinks what a renovation loan or cash-out can be sized to. Landed property and vacant land need SLA approval.
• United States, Switzerland, Liechtenstein, Norway and Iceland nationals. Taxed as citizens for ABSD, obtained through a remission application on the IRAS portal. Buying and financing the works are then as for a citizen, except that CPF is not available to a non-PR. A US green-card holder who is not a US national does not qualify, and a US citizen who is also a Singapore PR is charged at the citizen rate.

For US nationals and foreigners with US ties, US tax treatment of a home held abroad, and of money spent on it, is its own subject that this page does not settle. The US-passport essay is the place to start.

Taxes: what the works do, and do not do, to what you owe

Stamp duties are on the purchase, not the works

Buyer's Stamp Duty is charged on the price or market value of the property, on a progressive scale: 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, 5% on the next S$1.5m and 6% on the remainder. On S$2m that is S$69,600. Renovation spend does not enter that calculation, because it occurs after the transfer. ABSD works the same way, and is due in cash within 14 days of the signed contract, so it competes with the renovation budget for the same cash in the same month.

Seller's Stamp Duty is the tax on renovating and leaving

Since 4 July 2025 the holding period is four years, and the rates on a residential sale are 16% in year one, 12% in year two, 8% in year three and 4% in year four. It is charged on the higher of the selling price and the market value, so it applies to the whole price and not just the profit. Anyone who buys, renovates hard and plans to sell within four years needs a gross gain large enough to cover it, and the renovation cost, first. There is no general capital gains tax on a home in Singapore; gains are taxed only where IRAS treats you as trading.

Property tax

Owner-occupier rates apply to one property. A vacant residential property is taxed at the non-owner-occupier rates with no relief for being empty because you are renovating; a newly completed property is assessed from its TOP date. If you are rebuilding, IRAS has a remission that applies owner-occupier rates to land under construction in specified circumstances, and a demolished property's Annual Value is set on a formula basis. The IRAS pages returned navigation only in the runs recorded in the ledger, so I am not restating the rate tables here. I have not read whether renovation raises the Annual Value, and I will not guess.

Rental income and the interest question

If the home will be let, the renovation becomes an income-side question. IRAS treats renovation and refurbishment as generally capital expenditure, not deductible; the section 14N deduction is for businesses. A landlord can claim 15% of gross rent as deemed expenses, or actual expenses, and if you claim actual expenses on any one tenanted residential property the consistency rule applies. Mortgage interest on a loan taken to buy a rented property is deductible, and IRAS treats interest on loans taken specifically to finance income-producing assets similarly. Whether interest on a renovation loan used to prepare a home for tenants qualifies is a question I did not find answered in a page I could read; ask IRAS or an accountant before you assume it. Rental losses cannot be carried forward or set against other income such as salary; as an administrative concession, one property's rental loss may be set against another property's taxable rental income in the same year if all are let at market rates.

Borrowing: the rules that decide how much you can fund

Loan-to-value, read this run

MAS, on loan tenure and loan-to-value limits (last updated 27 March 2024, read this run): with no outstanding housing loan the limit is 75%, with at least 5% cash; with one it is 45%, and with two or more 35%, both with at least 25% cash. Where the tenure runs beyond 30 years (25 for an HDB flat) or past the borrower's age of 65, the lower limits of 55%, 25% and 15% apply, and non-individual borrowers face 15%. Loan tenure is capped at 30 years for HDB flats and 35 years for other property.

The consequence for works is that LTV applies to the purchase loan and to any cash-out loan, and renovation spend never enters the collateral value. A bank that values your condominium at S$1.8m before the works and S$1.8m after them has not lent you a cent against the renovation.

TDSR and MSR, read this run

MAS, on the MSR and TDSR rules (last updated 16 December 2021, read this run): your TDSR must be 55% or less, meaning all monthly debt obligations may take up to 55% of gross monthly income; MSR is 30% and applies to HDB flats and executive condominiums in their minimum occupation period. The 4% residential interest-rate floor and the 30% haircut on variable, bonus and rental income are from other MAS material recorded in the ledger, not from the page I opened. MAS sets minimums, and banks can be stricter.

Here is the part almost nobody prices. Take a S$30,000 renovation loan at 4.18% flat over five years (an assumed tenure; my arithmetic, not a bank quote). Flat interest is S$30,000 times 4.18% times five years, S$6,270, so you repay S$36,270 at S$604.50 a month. Because you repay principal gradually, the effective annual rate on the balance you actually hold is about 7.7%, roughly double the headline. And S$604.50 a month is debt: at the 4% floor over 30 years, that instalment would reduce the mortgage a bank will qualify you for by about S$126,600. The catch is timing. A renovation loan taken after the mortgage is approved does not reduce that mortgage, but it does reduce anything you try to borrow next, including a refinance or a cash-out. Take it before you apply, and it comes off the top of the purchase loan.

Now the alternative. A S$60,000 cash-out at 2%, the middle of the reported 1.4% to 2.5% range for home equity loans, repaid over ten years is about S$552 a month and S$6,250 of interest (my arithmetic): the same interest bill as the S$30,000 renovation loan, for twice the money. Add the reported set-up cost of legal S$2,000 to S$3,500 and valuation S$300 to S$600, and the all-in cost is roughly S$8,550 to S$10,350, still cheaper per borrowed dollar. The conditions: it needs private property with free equity, it is serviced in cash, and it carries a lock-in with a penalty typically around 1.5% for early exit. The ledger records that TDSR does not apply to an individual's MWL secured on an existing property within a 50% threshold; check the exact condition with the bank before you rely on it.

HDB loan or bank loan, and floating or fixed by phase

For an HDB flat, the HDB loan is a concessionary loan at 2.6% a year, pegged to the CPF Ordinary Account rate, with no lock-in and no early-repayment penalty. A bank loan can be cheaper: Stacked Homes found a bank loan at SORA plus 0.5% cheaper than the 2.6% HDB rate in 191 of the periods it examined. A bank loan carries a lock-in. An HDB loan can be refinanced to a bank at any time; the return trip is not allowed. That matters for works: moving to a bank loan for a lower rate is a one-way door, and it does not by itself give you cash for renovation.

By phase: the works phase is a completed-property phase, so the loan on the property can be fixed or floating. In September 2026 one aggregator shows 3M compounded SORA at 1.19% and the lowest two-year fixed rate at 1.40%, with floating packages priced at SORA plus a bank spread. If you are financing a rebuild you are in a different phase: banks typically cap a land loan at about 55% LTV against 75% for a completed home, and a construction loan is drawn in stages against progress. Rates and lock-ins change monthly, so these are markers of the ledger's date and not offers.

Reno, A&A and rebuild: costs and how each is financed

Renovation, addition and alteration, and rebuild are one spectrum of spending, and the financing changes as you move along it.

Renovation of an HDB flat or condominium

Reported costs from renovation guides: an HDB BTO three-room full renovation S$35,000 to S$55,000; an HDB resale three-room S$45,000 to S$75,000; a condominium two-bedroom S$24,800 to S$71,100. Guides suggest a contingency of 10% to 20% (one) or 10% to 15% (another) on top of the budget; on an S$80,000 budget the 10% to 20% range is S$8,000 to S$16,000, S$88,000 to S$96,000 in total. These are commercial pages and they differ from each other, so use them for order of magnitude and then get written quotes. At these sizes the S$30,000 bank loan cap covers a fraction of a resale renovation, which means most buyers fund the rest from cash or a cash-out.

Addition and alteration on a landed house

URA treats a proposal as a landed addition and alteration only within its tests: for example, additional gross floor area must not exceed 50%, and a proposal beyond the tests is treated as reconstruction. A Qualified Professional lodges the plans. Commercial cost pages put construction at S$180 to S$300 per sq ft for an A&A against S$300 to S$500 for a new build, and one adviser puts a major A&A on a 2,000-plus sq ft home at S$600,000 to S$1.2m, with a later re-read of the same page giving S$800,000 as the lower bound. A light terrace renovation is reported at S$80,000 to S$150,000. Where an owner retains structures that do not conform to current rules, URA requires certification by a Professional Engineer; that is a cost and a schedule risk to build in. [⚠ aa.cost.plb_reread_2026_09: sources differ; awaiting a ruling]

Rebuild

A rebuild is a construction project with a construction loan. One guide says a rebuild can be financed up to about 75% of the total rebuilding cost, drawn in stages against progress, while the land loan behind it is typically capped nearer 55%. Commercial sources put professional fees and contingency on top of construction, and demolition at S$30,000 to S$60,000. One architecture firm puts design and documentation at six to twelve months and construction at twelve to eighteen months, and three commercial sources disagree on total duration. Living elsewhere during the project is reported at S$3,000 to S$5,000 a month for twelve to eighteen months. That is the financing gap: interest on land and construction draws, plus rent, plus the contingency, all before the house exists. [⚠ rebuild.cost.demolition_three_sources: sources differ; awaiting a ruling]

CPF has one exception that does apply here. The CPF Board page lists a loan taken for the construction of your house and the purchase of vacant land among the uses of Ordinary Account savings, so a construction loan can be repaid with CPF, subject to the limits in the ledger. That is the only sense in which CPF funds building work, and it does not extend to renovating an existing house.

Conveyancing: where the renovation money gets tied up before you have the keys

A purchase with a mortgage takes about ten to twelve weeks from signing to completion in one law firm's guide. Three conveyancing items bear on renovation financing. First, the mortgage: the bank appoints its own lawyer for the mortgage side, mortgage duty is 0.4% of the loan capped at S$500 as excerpted from IRAS, and SLA charges S$68.30 to register each transfer or mortgage. Second, the valuation: the bank appoints a valuer from its own panel and you cannot choose, and if the price exceeds the valuation the buyer pays the difference in cash, which reduces what is left for works. Third, a cash-out or refinance after completion is a second conveyancing job: reported legal cost S$2,000 to S$3,000 and valuation S$200 to S$500 for a refinance, S$300 to S$800 admin for a repricing with no legal or valuation fee. Ask whether the bank subsidises legal fees and whether there is a clawback, typically three years.

For an HDB resale flat, CPF can pay legal fees and stamp duty, and the buyer's other charges are small. None of it pays for works. Two practical steps: get the renovation quotes before you exercise the option, so that the cash number you take to completion is real; and do not book contractors to start on completion day unless the cash for them is separate from the cash for completion.

Estate: what a renovation loan does when you die

A renovation loan is a personal debt, separate from the mortgage. In the ordinary case it is an unsecured debt of the estate, and nothing I read says the Home Protection Scheme or a mortgage-reducing term policy covers it: HPS is mortgage-reducing cover on an HDB housing loan, and MRTA is a decreasing policy that pays the outstanding mortgage. That is my reading; check the policy wording. Where property is held in joint tenancy the survivor takes the share automatically, but the debt does not vanish, and CPF savings are not covered by a will and do not form part of the estate; they pass by CPF nomination or, with none, via the Public Trustee under intestacy rules, on a track entirely separate from the property. A will and a CPF nomination are separate documents that do separate jobs. An A&A or rebuild in progress at death is a live construction contract, and an executor inherits the contractor, the loan draws and the insurance.

Insure the works while they happen. Contractor's all-risk insurance for renovation is reported at a cost you should have the contractor evidence with a certificate; employers must carry work injury compensation cover for their workers; home contents cover includes renovation works. A homeowner policy may be void if you rent the home out, so tell the insurer.

The twelve questions, in plain words

Two questions that sort you

Nobody buys an asset believing it will fall, so asking whether you buy to invest or to stay sorts no one. Ask two things instead. Q1: are you borrowing to buy? Q2: once you hold it, are you lending it out? Cash and own-use is pure appreciation with no carry. Cash and let-out is yield, with positive carry by construction. Borrowing and own-use is negative carry by construction: most owner-occupiers are here and few say so. Borrowing and let-out is the spread play, and the gap between rent and financing cost is the whole game. A renovation adds a further fact to whichever square you are in: money spent that does not show up as value.

C0. The play

Renovating your own home is neither a balance-sheet play nor a cash-flow play. It is consumption that looks like an asset. You are spending money to change how the home works for you, and the balance sheet moves by much less than the spend. If it is funded with debt, it becomes a cash-flow problem with no income attached. If the home is let out it can become a cash-flow play, but only if the rent rises by more than the cost of funding the works, and the claims that a renovated home rents or sells for enough more to pay for itself come from contractor and portal guides that I could not confirm. Treat them as claims.

C1. Balance sheet

What you own and what you owe. Own: the home, at the valuer's number, which the works may not raise. Owe: the mortgage, plus whatever route you used for the works. A renovation paid from cash swaps a liquid asset for a less liquid one at a haircut. A renovation loan adds a liability with nothing behind it except your income. A cash-out adds a liability secured on the home you already own and lowers the equity in it by the amount drawn. In all three the asset column grows by less than the spend.

C2. Cash flow

What actually moves, and when. Out on or before completion: option fee, downpayment, ABSD if any, legal fees. Out after completion: mortgage instalments from the first month, property tax, contractor deposits and progress payments, the MCST deposit, permit costs, temporary housing if you cannot live there, and insurance. In: nothing, if you live there. Where the funding gap is: in the weeks between completion and move-in, when the mortgage runs, the rent runs and the contractor's progress payments run, and CPF can fund only the mortgage. The gap is largest for the buyer who put every available dollar into the downpayment.

C3. Profit and loss

What it does to profit, which is not the cash. An owner-occupier has no income statement, but the concept still separates costs that are gone (renovation, interest, duties, agent fees) from the cost that comes back to you as equity (mortgage principal). The renovation is expense-like: IRAS treats it as generally capital and it is not deductible against income; for a landlord it does not reduce taxable rent. Interest on the renovation debt is gone. Principal repaid is not. Two years in, a buyer can have less cash and a home worth what was paid, while the profit and loss reads as a run of losses that were never a cash shortage until they were.

C4. Carry

Income minus financing cost. For an owner-occupier the income is nil and the carry is negative by construction: the mortgage interest plus the renovation financing. On the S$30,000 example above the flat interest alone is about S$6,270 over five years. For a landlord the question is whether extra rent covers it. Average gross yield for non-landed private homes is reported at about 3.4% in 2026, and net yields for non-residents at 1.5% to 2.5% after tax and costs; on a S$1.5m home one per cent of net yield is S$15,000 a year, which is the scale to set S$6,270 of interest against.

C5. Give and get

You give cash, or borrowing capacity, or equity in a property you already own, in exchange for a home that suits you better, sooner. You get comfort and function, and sometimes a better rent or a better sale. On the evidence I could read, you do not reliably get the spend back at sale.

C6. Exposed to

Cost overruns, since the contingency guides say 10% to 20%. Interest rates, if the funding is floating. Contractor failure, which is why the HDB directory and insurance certificates matter. A valuation that does not move. A forced sale inside the SSD window. Income shocks, because every renovation instalment sits in your TDSR. And for a landed A&A, the risk that URA classifies your project as reconstruction, which changes the approvals and the loan.

C7. For how long

Five years for the typical renovation loan I illustrated; ten to twenty for a cash-out; a lock-in of about two years on a refinance with a penalty around 1.5%; the SSD window of four years if you might sell; and for a rebuild, roughly two to three years of design and build before you live in it. The home itself is a horizon of decades.

C8. Failure cascade

If it goes wrong, it goes wrong in an order. First, negative carry: the renovation and mortgage instalments together exceed what your income comfortably carries. That hits cash flow, because the instalments are due whether or not the works are finished. Cash flow accumulates into the profit and loss as interest, penalties and overruns. The renovation spend never re-appears in the valuation, so equity is thinner than the cash you put in, and if prices soften it can turn negative. Negative equity leads to illiquidity: you cannot refinance, cannot cash out, and cannot sell without paying the shortfall in cash, and inside the SSD window you pay duty on the sale as well. Illiquidity, if income then fails, leads to insolvency. The way to break the chain is at the first link, by sizing the works so that the mortgage and renovation instalments together stay well inside your TDSR headroom.

C9. Liquidity

Cash you put into works does not come back as cash. There is no market in a bathroom. A cash-out takes two to four months to arrange, so it cannot be your emergency fund; a bank renovation loan is quick but small. If you need the money back the only routes are to sell or refinance, and a private resale takes weeks to months to complete. The haircut on works is whatever the next buyer declines to pay for. For a landed house valuers depreciate the building and value the land, so the haircut on a rebuild can be large.

C10. Control

You are a price-taker on interest rates, on the valuer's number and on what the market pays at sale. You are not a price-taker on scope. Renovation, addition and alteration, and rebuild are this page's expression of control: they are where your decisions change the outcome directly. You choose what to spend, what to defer, which contractor, which finish, and whether a wall comes down. Control has a cost, because every dollar of control is a dollar of exposure to overrun. The strongest control is a fixed-price contract, a contingency you have already funded, and a phased plan that lets you stop halfway with a habitable home.

C11. The exit

You exit by selling, or by refinancing to release equity. Selling inside four years costs seller's stamp duty at 16% falling to 4% of the selling price, plus the seller's agent commission. A cash-out or refinance inside the lock-in costs around 1.5% of the outstanding loan. A half-finished home is hard to sell. For an HDB flat, the exit is governed by the minimum occupation period and HDB resale rules, and the renovation spend is not part of the price you get back unless a buyer chooses to pay for it.

For businesses: what lenders, brokers, designers and contractors can do with this page

This section is for the firms that sit around a renovating buyer: mortgage brokers, banks with renovation and equity products, interior designers, contractors and management agents. The page tells the buyer that renovation is a cash problem first and a financing choice second. That is true and it is not a sales pitch for any one of you.

A mortgage broker's real offer is the comparison this page cannot do: the live effective rate on a renovation loan against a cash-out, sized against the buyer's actual TDSR and CPF-adjusted equity, with the lock-in and clawback in writing. The number a broker can give and a page cannot is the buyer's own headroom. A designer or contractor who wants to be found by this reader should publish the payment schedule with the price, name the stage payments, show the certificate of insurance and the HDB or URA permit route, and separate the contingency line from the base price. A firm that offers or arranges credit is on different ground: licensed moneylenders are capped at 4% a month, an administrative fee of up to 10% of principal, and a total-charges cap. If a firm is lending it should be licensed, and if it is introducing a lender it should say so.

What the buyer gets from a firm that works to those rules: a plan in which the works are sized to the cash and the debt, in that order, and a schedule that is honest about the gap between completion and move-in.

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

CEA (last updated 13 May 2026) says commissions are not fixed and are negotiable, and that consumers should pay only the property agency. A seller pays about 2% on a private resale, or about 1% on an HDB resale, and the buyer's agent is paid by co-broke from that or by the buyer directly where agreed — one agent may never collect from both sides of the same transaction; on a new launch the developer pays the buyer's agent, typically 2% to 3%, and the buyer pays nothing. On a S$1.5m condominium, 2% is S$30,000 in total, and I do not have a sourced number for the buyer-side share of it. A market-reported median for agent income is about S$72,000 a year, with new agents at S$10,000 to S$40,000 in their first year.

Where the incentive points, including against the person writing this page. The agent is paid when the deal completes and is paid nothing for a deal you talk yourself out of. If you tell an agent that the renovation budget is what makes the purchase unaffordable, the agent's interest is in your finding the money and not in a lower price or a later date. That is my own incentive as much as anyone's. A buyer who stretches to the maximum loan and leaves nothing for works is the most profitable client to close and the most likely to be short of cash in month two. Two further points. An agent may not collect commission from more than one party in the same transaction, and a Prescribed Estate Agency Agreement must be signed before the agent acts. And I have not found a sourced figure for how common referral fees from designers, contractors or brokers are: if your agent recommends a designer or a lender, ask whether there is any fee, and get the answer in writing.

What to do about it: before you sign the option, ask for the total cash you will need on the day of completion and for the first six months after it, with the renovation inside the number. If the agent cannot produce it, work it out on this page and ask again. It is a free question, and the answer is the difference between owning a renovated home and owning a mortgage on a building site.

What I could not verify this run

• The HDB renovation guidelines, URA A&A and BCA pages returned errors when I opened them (404 or 500); the rules on permits, contractors, the 50% GFA test and qualified professionals are carried from earlier reads in the ledger.
• The CPF Board page I read (last updated 6 July 2026) lists the permitted housing uses and does not mention renovation. The ledger's explicit rule that CPF cannot be used for renovation, improvement or repair rests on an earlier read.
• The MAS pages I read do not contain the 4% floor or the 30% variable-income haircut; those are from other MAS material recorded in the ledger.
• IRAS pages on stamp duty, property tax and rental deductions returned navigation only in the runs recorded in the ledger; the BSD, ABSD, SSD and property tax figures rest on those earlier reads.
• Renovation costs, bank renovation loan terms, home equity loan rates, set-up costs and rebuild costs are from commercial guides that I did not reopen. Where they disagree I said so; the 4.18% flat quote is from a search-result summary.
• The worked examples (S$30,000 at 4.18% flat over five years, the S$126,600 TDSR effect at the 4% floor over 30 years, the S$60,000 cash-out at 2% over ten years) are my arithmetic on assumed tenures, not bank quotes.
• I have not established whether renovation raises Annual Value for property tax, whether interest on a renovation loan is deductible for a landlord, or whether HPS or MRTA cover a renovation loan. All three need a primary source.

Where to go next

• /borrow/equity-loans for cash-out against a property you own
• /borrow/refinancing for switching or repricing the mortgage
• /borrow/hdb for the HDB loan and what happens when you leave it
• /borrow/upgrading if you are selling one home to buy another
• /realty/rebuild/renovation for the buyer-side view of works
• /realty/rebuild/a-and-a-vs-rebuild for scope
• /borrow/bridging for timing gaps
