Improving it before you sell: does the spend come back in the price?

You are not planning to live in the finished result. You are weighing whether to spend on the house you already own so that the house sells for more, or sells faster, or both. That is a different question from whether to rebuild a home to live in, and it deserves its own page rather than a paragraph at the bottom of a rebuild page. I am a realtor, not an architect, a Qualified Person or a valuer. What follows is the property, tax, lending and legal mechanics of spending on addition and alteration (A&A) or renovation before a sale, read from government pages where I could read them, and from contractor and portal guides where I could not, with the difference marked every time. Every figure carries its source and its date.

The short answer

No renovation or A&A converts dollar for dollar into a higher sale price. That is the position across every source I could find, and it holds for two independent reasons that do not depend on each other. First, a bank's valuer prices a landed house as land first, at a comparable land rate, and treats the building as a depreciating asset behind it: a structure 20 years old or more contributes little, and decade-old cosmetic work is largely not recovered. One mortgage adviser's own worked example puts a 15-year-old renovation at S$200,000 to S$400,000 of added value on a S$4.8 million land basis, far below what it cost to build. Second, a buyer of a resold house prices it against comparable sales and location, not against your receipts, so a rebuild or A&A premium is commonly reported as partially or fully unrecoverable on exit. Contractor and portal guides selling the work claim renovation can raise resale value by 15% to 30% and that A&A adds around 10% to 20%; the same page of claims also says a renovation over S$80,000 on a landed home will often not be recovered because a buyer who dislikes it replaces it, and that strategic kitchen, bathroom, paint and landscaping work returns the most of any category. None of these percentages names a base price, none of the pages carrying them was opened directly this run, and the party making the claim sells the renovation. Read them as the sales pitch you will hear from every contractor who quotes you, not as a number to plan around.

So the honest framing is not "will this pay for itself" but "how much of this will I get back, and is the rest worth paying for the sale I get instead." The rest of this page works through what decides that fraction: what the work is allowed to be, what it costs you in tax and time while you hold it, how it is financed, and what it does to your position under the twelve questions I use on every page on this site.

The mechanics: what the work is allowed to be, and why that still governs a presale project

Spending on a house before selling it is still, in law, either an addition and alteration or a rebuild, or repair and maintenance that needs no lodgment at all, and which one it is decides the approvals, the timeline and the paperwork a buyer's lawyer will ask for later. URA's guideline on additions and alterations to a landed house, last updated 13 July 2026, sets three 50% tests at once: added gross floor area must not exceed 50% of the existing approved gross floor area, external walls removed and replaced must not exceed 50%, and structural changes must not touch more than 50% of the existing floor area. The entire roof may be changed or replaced, whatever the height increase, as long as it adds no storey; an attic may be added if it fits inside the 50% GFA limit. A proposal that cannot meet these must be lodged as a new erection or reconstruction, which is a rebuild in law however much of the old house you keep, and carries the longer, costlier profile covered on the A&A-versus-rebuild page. Where the house already exceeds the current building envelope, new A&A work must not increase its bulk further; URA assesses such a case on its merits, which is a slower, less certain approval than a straightforward lodgment.

A landed A&A is lodged by a Qualified Person, a registered architect or engineer, with a proposal plan, sketch plan and declaration of compliance; the authorisation is valid two years from the acknowledgement letter, extendable up to two times. If your plan is cosmetic only, repainting, refitting a kitchen, replacing finishes, none of this lodgment machinery applies and the work can start on a contractor's schedule alone. The moment the brief adds floor area, moves a structural wall, or changes the roof form, you are back inside URA's and BCA's process, and that process runs on its own clock regardless of when you want to list the house.

This matters for a seller specifically because unapproved work is a defect that surfaces at the worst possible time: when the buyer's lawyer asks for approved plans and completion certificates against every alteration visible in the house. Work finished with its paperwork is an asset at the point of sale. Work done without lodgment, however good it looks, is a gap in the record that a buyer's bank may price into its own valuation or simply refuse to lend against, which can stall or kill the sale you did the work to help.

Eligibility: who can authorise the work, and on what house

There is no licence needed to renovate your own home; eligibility here is about title and structure, not qualification. Every co-owner on the title has to agree, since a Qualified Person's lodgment and a builder's contract both need the owner's signature and a bank with a charge over the house may have its own conditions in the loan terms worth checking before you commit to a contract. The approved plans on file have to match the house as it stands: an older, unlodged extension does not count as existing approved area when URA measures the 50% tests, so a first paid step worth taking, before any design spend, is confirming what URA actually has on record for your plot. A strata-landed unit inside an approved condominium is governed by its management corporation and by-laws, not by the landed A&A guideline, so clear any presale works with the MC before spending on design.

Your citizenship status changes what the works are worth doing against

The works themselves are open to any owner regardless of citizenship; what citizenship changes is the tax exposure on the transaction the works are meant to help, particularly where a sale is timed against a purchase. ABSD is charged by count of residential properties and by citizenship: a Singapore Citizen pays nil on a first property, 20% on a second and 30% on a third and beyond; a Permanent Resident pays 5% on a first, 30% on a second and 35% on a third; a foreigner pays 60%, and an entity or a trust 65%. Nationals of the United States, Switzerland, Liechtenstein, Norway and Iceland, and their equivalent PRs under the respective free trade agreements, are taxed as citizens, obtained by a remission application rather than automatically.

The reason this belongs on a presale-improvement page: if you are financing the works from equity in the house you are selling, or if the plan is to sell this property and buy the next one, the ABSD math on the replacement purchase, and the six-month clock on any married-couple refund, run on their own schedule that has nothing to do with when your contractor finishes. A rebuild or a long A&A that overruns its timeline can push your purchase of the next home into a window where you are technically still holding two properties, at the second-property ABSD rate, while the first is mid-renovation and not yet sellable. Sequence the sale, not just the work.

Taxes: BSD, ABSD, SSD, property tax and rental income while you hold it

BSD and ABSD: not on the works, but on what comes after

Buyer's Stamp Duty and ABSD are charged on acquisition, not on works to a property you already own, so spending on A&A before a sale attracts neither. BSD runs on IRAS's banded schedule; on a S$2,000,000 purchase it is S$69,600. Both duties become live again the moment you buy the next property, on the citizenship rates above, and that is the number a seller doing presale works should be running well before listing, not after.

SSD: the clock a presale project can eat into

Seller's Stamp Duty applies to residential property sold within four years of your own acquisition: 16% in year one, 12% in year two, 8% in year three, 4% in year four, nil after, effective for property bought on or after 4 July 2025 (an earlier three-year schedule at lower rates applies to purchases before that date). This is the tax that turns a presale renovation from a cosmetic decision into a timing decision. A standard A&A runs about 6 to 9 months from design to completion on one contractor's figures, and a full rebuild 18 to 24 months or more on the same source; if you bought the house inside the last four years and plan A&A work before selling, run the finish date against your own SSD clock, because a listing that slips past a year-boundary can cost you a full duty tier on the sale price, a bigger number than most renovation budgets on this page.

Property tax while the house sits mid-works

If you still occupy the house during the works, owner-occupier property tax rates continue to apply, tiered from 0% on the first S$12,000 of Annual Value upward. If you move out for the duration, and the house therefore stands vacant, IRAS taxes vacant residential property at the non-owner-occupier rates with no relief for the vacancy, a materially steeper schedule. I found no IRAS statement on whether a house mid-A&A, rather than simply empty, is assessed the same way as an ordinary vacancy; ask IRAS or your conveyancing lawyer before assuming the owner-occupier rate survives a period of works you are not living through.

Rental income is a separate question only if you let the house between finishing the works and completing the sale; it is taxable, with a 15% deemed-expense election available in place of actual expenses. Most sellers doing presale works do not let the house in that gap, since a tenant complicates access for viewings, but the option and its tax treatment sit on the landlord pages if you consider it.

Borrowing: LTV, TDSR, MSR, and how the works themselves get paid for

The mortgage on the house you are selling is unaffected in mechanism by A&A or renovation works, but financing the works is its own borrowing decision, made against a house you intend to sell within a defined horizon rather than hold indefinitely. CPF cannot be used at all: the CPF Board's own rule states CPF savings cannot fund renovation, improvement or repair work on your property, no exceptions listed, so every dollar of a presale project is cash or a cash-serviced loan. The common route against equity already in the house is a home equity loan, reported in the range of 1.4% to 2.5% a year, with legal costs of roughly S$2,000 to S$3,500, valuation of S$300 to S$600, and an early-repayment penalty of 1% to 1.5% of the outstanding loan if you sell and discharge it sooner than planned, which, on a house you are about to sell, you likely will. That penalty is a real line item against the return on the works and is rarely in a contractor's pitch.

For context, if the works are large enough to be financed like a purchase rather than a top-up, the first-loan LTV limits are 75%, or 55% where the tenure runs past 30 years or past age 65, and TDSR is tested at a 4% floor rate for residential property, 5% for non-residential, against your gross monthly income; MSR at 30% applies only to an HDB flat or an EC within its minimum occupation period, and does not reach a private landed or condo sale. None of this changes what you owe on the house you are selling, but it bounds how much cash a lender will actually extend you to fund the works in the first place, separate from whether the works are worth doing at all.

What the work costs, and what fraction of it you should expect back

Construction cost for A&A work runs S$180 to S$300 per square foot on one 2026 contractor guide, with a standard A&A taking 6 to 9 months from design to the Certificate of Statutory Completion, including 2 to 3 months of regulatory submissions; a full reconstruction on the same source runs 18 to 24 months. A separate architecture firm frames the ceiling on how far a presale A&A can sensibly go: an extensive A&A, one that touches the structural frame, all the M&E systems and the layout, can approach 60% to 80% of the cost of a full rebuild, without the benefit of a clean structure to show for it. That comparison is the practical test for a seller: past a certain point, you are paying rebuild-adjacent money for a house that a valuer will still price as an old building on land, and the fraction you recover on exit falls as the spend rises past cosmetic work.

Put the sourced pieces together and the shape of the answer is this. Cosmetic work, repainting, refitting, landscaping, the categories contractor guides themselves say return the most, is the safest presale spend because it is the cheapest and the fastest, and it does not touch the valuer's land-first, building-depreciated method described above. Structural A&A is a harder case: it is not free, a bank's valuer credits recent structural work more than decade-old cosmetic work because a buyer avoids the construction cost and risk of doing it themselves, but the recovery is reported as partial, not dollar for dollar, and the clock (6 to 9 months at best) has to clear before you list. A full rebuild before selling is very rarely the right trade on this page's own numbers: the cost approaches or exceeds the value most sources credit for even a well-executed structural upgrade, the build runs 18 to 24 months or more, during which the SSD clock, the property-tax exposure and the carrying cost all run against you, and the resale premium a rebuild commands is itself reported as commonly unrecoverable against what was actually spent.

Conveyancing: what the buyer's lawyer will ask for, and when to have it ready

None of the presale works themselves are conveyancing; conveyancing happens at the sale that follows. A typical transaction with a mortgage runs about 10 to 12 weeks from signing the option or sale and purchase agreement to completion, with a lawyer typically acting for the buyer and coordinating with your lawyer, the buyer's lender and SLA. Private conveyancing fees run roughly S$2,300 to S$3,200 plus 9% GST and disbursements on the ledger's own figure for a condominium transaction; a landed transaction is priced individually and I have no sourced figure for it. What the works add to that process is documentation: the buyer's lawyer and their bank's valuer will both ask for the approved plans and completion certificates for anything visible that was not part of the original approved structure. Have that paperwork assembled before you list, not after an offer, because a gap discovered during due diligence is a negotiating point for the buyer, not for you.

Estate: where this decision belongs to more than one person

A house held or inherited jointly raises the presale-improvement question before the sale question does, because spending on works needs every co-owner's agreement in a way that simply listing the house as-is may not. There is no estate duty in Singapore for deaths on or after 15 February 2008, so an inherited house carries no inheritance tax at any value; no stamp duty is payable on the transfer of a deceased's property to a beneficiary by way of assent, and ABSD does not apply where a residential property passes to a beneficiary under a will or the rules of intestacy. None of that changes the practical point: siblings who inherit a house often disagree about whether to spend on it before selling, and a co-owner who disagrees can be a harder blocker to a renovation than to a straight sale, since a sale needs only agreement to sell while works need an ongoing agreement on scope, contractor and cost as the project runs. Settle who is deciding, and who is paying, before the first contractor quote, not after.

The twelve questions, applied to spending before a sale

This is the frame I use on every page on this site: twelve plain questions, in order. Two questions sort the reader before the rest apply, and neither of them is "are you buying to invest or to live in it," because nobody buys an asset believing it will fall, so that question sorts nobody. The first sorting question is: are you borrowing to buy? On this page, read "buy" as "buy the works," cash from your own funds or a loan against the house. The second is: once you hold it, are you lending it out, meaning letting it, in the gap between finishing the works and completing the sale? Together they give four positions.

• Cash, and you keep living in it through the works: pure appreciation, no carry. You spend and hope the sale price absorbs it. Nothing is owed, so nothing forces your hand, but nothing forces the market to agree with you either.
• Cash, and you let it out in the gap before selling: a small, temporary yield against a project whose whole purpose is to end in a sale, not to run as a rental. Most sellers skip this because a tenant complicates viewings.
• Borrowing, and you live in it through the works: negative carry by construction, on top of a project that itself may not fully return its cost. This is the position that needs the SSD clock and the equity-loan early-repayment penalty checked before signing anything.
• Borrowing, and you let it out in the gap: the least common position on this page, and the one where the financing cost, the rental income, the SSD clock and the works timeline all have to line up at once for the arithmetic to work.

Find your position first. The same renovation quote looks like a different decision from each of the four.

C0. The play: balance sheet or cash flow?

This is a balance-sheet play, not a cash-flow play, and it is worth saying plainly because the sales pitch you will hear ("it pays for itself") is a cash-flow argument dressed up, implying the spend returns itself like an investment yields income. It does not produce income. You are spending money now to change what the house is worth on a single future date, the date of sale, and the whole page above says that conversion is partial at best. Treat every renovation quote as capital spent against an uncertain, partial return on one transaction, not as a cost you will earn back over time the way a landlord earns back a fit-out through rent.

C1. Balance sheet: what you own and what you owe

Before the works: the house, and whatever mortgage stands against it. During the works: the same house, plus a temporary rise in what you owe if you finance any of it, and, until the sale completes, no change in what you own that a valuer will fully credit, since a valuer prices the land first and the building at its depreciated value regardless of what you just spent. After the sale: the loan is discharged from proceeds, the equity loan's early-repayment penalty comes off the top if you took one, and what is left is your balance sheet in cash. The one-line test: does the incremental price the works are reported to add exceed the incremental debt and penalty you took on to build it, after the fraction lost to depreciated-building valuation. On the sourced ranges above, that test fails more often than contractor pitches suggest.

C2. Cash flow: what moves, and where the gap is

This is not the same as C1 and not the same as C3 below; conflating them is the error the operator's own frame exists to prevent. Cash out starts with the contractor's progress claims, plus the Qualified Person's fee if the works need lodgment, plus GST, running on the works' own 6-to-9-month or longer clock. Cash in arrives only once, at completion of the sale, months after the last renovation invoice is paid. The gap between the last dollar spent on the house and the first dollar received for it is the funding gap this page is really about, and it is filled by your own cash, by an equity loan serviced entirely in cash since CPF cannot touch it, or by both. Underfunding that gap is the single most common way a presale project turns a discretionary improvement into forced urgency at listing.

C3. Profit and loss: what it does to profit, which is not cash

IRAS treats renovation and refurbishment on a private residence as capital spending, not a deductible expense, and a private seller has no income statement for the works at all: no income, no deduction, while the works are underway. The profit or loss on the whole exercise arrives once, at sale, as price received less everything put in: purchase price, the works, any interest on money borrowed for them, and Seller's Stamp Duty if the sale falls inside your own four-year window. Gains on a private property sale are generally not taxed unless you are found to be trading in property, so the arithmetic that matters is your own, not IRAS's: sale price, minus original cost, minus works and their financing cost, minus SSD if it applies, minus agent commission. Run that subtraction before the first contractor quote, not after the sale, because the sourced recovery fractions above suggest it is closer than a renovation pitch implies.

C4. Carry: income minus financing cost

For most sellers doing presale works, income is zero throughout, because the house is not let, so carry is simply the negative of whatever you are paying in interest on an equity loan or a top-up facility, at the 1.4% to 2.5% range reported for that product. On a S$300,000 equity draw at the middle of that range, roughly S$5,000 to S$6,000 a year in interest, small against the works themselves but real against a project that may take the better part of a year to complete and then several more weeks to sell. If you let the house in the gap before completion, carry can turn briefly positive, but this is the least common position on the page precisely because a tenant works against the reason you are doing the project.

C5. Give and get: the trade, stated plainly

You give the cost of the works (S$180 to S$300 per square foot for A&A, on one 2026 source), months of disruption or vacancy, financing cost if you borrow, and the risk that the spend simply does not convert into price the way the pitch implied. You get a house that may sell faster, may sell at a somewhat higher price, and, if the works were lodged and approved, arrives at the buyer's lawyer's desk with clean paperwork instead of a gap in the record. What you do not get, on every sourced figure on this page, is any assurance that the spend returns dollar for dollar, and the extensive end of the range, an A&A running 60% to 80% of a full rebuild's cost, is priced close enough to a rebuild that the rebuild's own poor recovery economics start to apply to it too.

C6. Exposed to: what can move against you

Five things. The valuer: a bank's panel valuer, not you, decides what a buyer's lender will lend against, and that valuer's land-first, depreciated-building method is the single biggest reason a renovation's sale-price uplift can fall short of a contractor's estimate. The market: URA's own price index moves quarter to quarter, and a project that runs long can finish into a softer quarter than the one you priced against. The clock: SSD if you bought inside four years, and the tax exposure on a vacant or mid-works house if IRAS treats it as vacant. The contractor: cost overruns and schedule slips extend every other exposure on this list, and a licensed builder's insurance and BCA licence class are worth confirming before signing. And taste: a buyer who dislikes your finishes may simply discount them or plan to redo them, which is the contractor guides' own admission, buried inside their sales pitch, that a renovation over roughly S$80,000 on a landed home is often not fully recovered for exactly this reason.

C7. For how long: the horizon you are committing to

From the first contractor conversation to a completed sale, the realistic horizon is the works' own timeline (6 to 9 months for a standard A&A, longer for anything structural) plus a normal marketing and conveyancing period of roughly 10 to 12 weeks once you list. Call it 9 to 14 months from decision to cash in hand for a straightforward A&A, and materially longer for anything approaching rebuild scope. If you bought the house within the last four years, the SSD clock is a second, independent horizon running in parallel, and if you plan to buy a replacement property, the six-month ABSD refund clock on the earlier home is a third. Do not start a presale project if you may need the proceeds inside that combined window.

C8. Failure cascade: if it goes wrong, in what order

The order is the same on every page on this site: negative carry, then cash flow, then profit and loss, then negative equity, then illiquidity, then insolvency. Here it typically starts smaller than a rebuild's cascade but starts the same way. A cost overrun or schedule slip first worsens carry, since interest on any borrowed portion keeps running past the date you expected to be listing. Second, it strains cash flow, because the funding gap between last invoice and first sale dollar widens. Third, it shows up in profit and loss only once you sell, when the total spent (works, financing, holding costs, SSD if it applies) exceeds what the valuer's land-first method and the market were ever going to credit you for. Negative equity from a presale project alone is rare, since most sellers are not financing the bulk of the works against a thin equity cushion, but it is not impossible on an equity-loan-funded structural A&A that overruns badly. Illiquidity follows if you cannot sell at the price needed to clear the works loan plus the mortgage, and insolvency is the end state only reached if you were already carrying thin margins before the project started. The practical brake: keep the works small enough, and the funding cash-only enough, that a bad outcome costs you a disappointing sale rather than a forced one.

C9. Liquidity: how fast this becomes money again, and at what haircut

A house mid-renovation is not a liquid asset at all; you cannot sell it for anything close to its finished value while it sits half-done, and a distressed sale of a gutted or partially-built house prices closer to land value than to your invested cost. Once the works finish and the house is listed, liquidity reverts to the ordinary market for your property type, plus whatever SSD haircut applies inside four years (16%, 12%, 8% or 4% of price by year) and the roughly 2% agent commission norm on the sale itself. The lesson for sequencing: do not begin a presale project with money you might need on short notice, because the illiquid window is the works' full duration, not just the marketing period after.

C10. Control: can you move the outcome, or are you a price-taker?

This is the page's own question, and A&A, renovation and rebuild are its expression at different points in a property's life: the same lever, different clothes, whether the house is one you plan to live in for decades or one you are improving to sell in months. What you control here: scope (cosmetic versus structural, and therefore which side of the 60-to-80%-of-rebuild-cost line you land on), the contractor, the specification, and the listing date once the works are done. What you do not control: the valuer's method, which prices the building as a depreciating asset regardless of how recently you touched it; the buyer's taste, which can discount finishes you paid a premium for; and the market quarter you happen to list into. The highest-control, lowest-risk version of this page's question is cosmetic work only, finished on a short, predictable timeline, priced in cash. The lowest-control version is a structural A&A financed with debt, timed against a tight SSD or ABSD clock, betting on a valuer and a buyer to agree with the contractor's pitch.

C11. The exit: how you get out, and what getting out costs

Three ways out of a presale project, not five, because you are not choosing whether to hold the asset afterward, only how the works end. One: finish the works, list, and sell, paying SSD if inside four years, agent commission at the roughly 2% market norm, and conveyancing fees, with the works' cost and financing already sunk into the price you get. Two: abandon the works partway and sell as-is, which a buyer will price as a half-finished house, generally the worst exit on this page since it captures none of the upside and all of the disruption. Three: abandon the sale plan entirely and simply keep the improved house, in which case this was never really a presale project and the A&A-versus-rebuild and rebuild-cost pages are the more relevant reading. Decide, before the first contractor quote, which of the three you are actually prepared to execute if the market or the works do not cooperate.

For architects, contractors, stagers, valuers and conveyancers

For a professional serving a seller at this decision point, this page is a map of where the money and the risk sit. The commercial pitch this market runs on, that renovation returns 15% to 30% and A&A returns 10% to 20% of its cost in sale price, comes from the guides selling the work, is unverified against any base price, and sits next to the same guides' own admission that spend over roughly S$80,000 on a landed home is often not recovered. A contractor, architect or stager quoting a seller should expect that seller to ask for a comparable sale to test the claim, and the honest answer, on every sourced figure I could find, is partial recovery at best, worse for structural work priced near the 60% to 80% of full-rebuild-cost band. A valuer's own method, land first and a depreciated building, is the single hardest constraint on any of these pitches and is worth stating to the client before, not after, they sign a contract.

The commercial incentive here is straightforward and worth naming: a contractor is paid on the contract sum regardless of what the house eventually sells for, a stager is paid on the engagement regardless of outcome, and neither carries any of the downside if the valuer or the buyer disagrees with the pitch. A conveyancing lawyer's interest is more aligned with the seller's, since unresolved lodgment gaps become their problem at completion; a lawyer engaged early, before the works start, can tell a seller in writing whether the planned scope needs URA and BCA lodgment at all, which is cheaper to know before the contract is signed than after the buyer's lawyer asks for a completion certificate that does not exist.

If you are one of these trades and want sellers at this decision point routed to you with the tax clock and the lodgment question already in front of them, the route is the work-with-me page.

What the realtor earns, and where the incentive points

On the works themselves, a realtor earns nothing at all; commission is paid only on a completed transaction. The moment a realtor is paid is the eventual sale, on the market norm of roughly 2% of price, paid by the seller, with the buyer's agent typically paid by co-broke from that; there is no fixed or prescribed rate, and an agent may not collect commission from more than one party in the same transaction. An exclusive listing agreement runs up to three months and keeps commission payable even if you sell yourself or through another agency within it.

Say the incentive plainly, including against myself. Because commission is a percentage of the final price, an agent has a real but small financial reason to encourage a seller to spend on presale works: a S$100,000 to S$300,000 uplift in sale price the works are claimed to produce adds only S$2,000 to S$6,000 to a 2% commission, a fraction of what the works themselves cost the seller. That gap means the advice to spend before selling is cheap for whoever gives it, whether that is an agent, a contractor or a stager, and expensive for the seller taking it, exactly the asymmetry the sibling A&A-versus-rebuild page names for a rebuild decision. It also means an agent who wants a fast, low-effort listing has an equal and opposite reason to advise against spending anything at all and to list the house as-is. Neither piece of advice is free of the person giving it.

Against my own interest: for a seller whose house is structurally sound and merely dated, the answer that earns me the least, do the cheap cosmetic work only and skip the rest, is also the one the sourced figures on this page best support. The protections that do not rely on my goodwill: CEA requires a Prescribed Estate Agency Agreement before an agent starts marketing the property, sets no fixed commission and leaves the rate to negotiation, and bars an agent from collecting from both sides of the same deal. Ask for a comparable-sale test of any renovation claim before you spend on it, and get the lodgment question answered in writing before the first contractor quote, not after.

What I could not confirm

• Read and quoted this run, 29 September 2026: URA on additions and alterations to a landed house (13 July 2026) and on non-conforming envelope cases (as excerpted in search results); IRAS on ABSD rates, BSD rates and computation, property tax rates, and stamp duty on a deceased's estate; MAS on TDSR floor rates and on loan tenure and LTV limits; CPF Board on renovation and repairs (7 November 2025); CEA on prescribed agency agreements, commission, dual representation and exclusive agreements; and the commercial pages of Vincent Lim, Joya Architects, Kenny Neo Advisory, PropertyLimBrothers, PropertyNet.SG, Yuen Law and a set of 99.co, PropertyGuru and contractor search-result summaries on presale renovation value.
• The headline renovation-value-uplift claims (15-30% for renovation, 10-20% for A&A) come from search-result summaries of commercial pages that were not opened directly this run; I could not confirm which source carries which figure, what base price they assume, or whether they control for the market moving independently of the works. Treat them as marketing claims, not statistics.
• I did not find whether IRAS treats a house mid-A&A and temporarily unoccupied the same way as an ordinary vacant property for property-tax purposes; whether a bank's construction or equity loan for presale works is assessed differently from an ordinary top-up loan under TDSR; or any sourced figure for how much faster, in days on market, a renovated landed house sells against an unrenovated comparable.
• The worked figures in this page (S$300,000 equity draw, the S$100,000-300,000 illustrative uplift against a 2% commission) are round numbers I chose to illustrate the arithmetic, not quotes or measured outcomes.
