Upgrading from your flat

About 13,480 HDB flats reach the end of their Minimum Occupation Period in 2026, across 22 projects in 14 towns, nearly double 2025's 6,970, with 5,909 four-room and 2,711 five-room flats named in the breakdown. That is the largest single dated cohort this site writes for. Almost none of that household will ask whether to upgrade; most decided that years ago, the day the flat's value crossed a number in their head. What they have not decided, and what no listing portal answers for them, is the order of operations: sell the flat first, then buy, or buy the condo first, then sell. That one decision moves a stamp-duty bill that can run to six figures, decides whether you carry two mortgages or a rental bill for several months, and sets how much cash you need in hand on the day you sign. This page treats sequencing as the product, because it is the actual decision, not the appreciation story around it.

The mechanics: two sequences and a gap between them

Sell first means: list the flat, wait for a buyer, complete the sale, bank the proceeds and the CPF refund, then go shopping for the condo with a clean cash position and a known Loan-to-Value tier. It is the cheaper route in stamp duty and the calmer route financially, and it costs you certainty of timing: you may be holding cash with nowhere to live and a rising market moving away from you, or renting somewhere in the gap. Buy first means: secure the condo, and only then sell the flat, inside a fixed clock the tax code sets, not one you choose. It preserves your negotiating position on the flat and avoids a rental gap, and it costs you a much larger cash outlay on day one, because Additional Buyer's Stamp Duty on the new purchase is paid upfront in cash if you still own the flat when you buy.

An HDB resale takes 8 to 10 weeks minimum after the Option to Purchase is exercised, on top of an average 60 to 90 days of marketing before a buyer is even found. Add those together and a realistic sell-first timeline runs 16 to 22 weeks, roughly four to five and a half months, from listing to completed sale, before you even start looking for the condo. Buy first collapses that wait into a single overlapping window, and the price of the collapse is the six-month clock that ABSD refunds run on, which the mechanics below cover.

• Sell first: register Intent to Sell, market the flat, accept an offer, exercise the Option to Purchase, complete the HDB sale (about 8 weeks after HDB accepts the application), receive sale proceeds and CPF refund, then buy the condo with a clean LTV tier and no ABSD.
• Buy first: exercise an Option on the condo, pay Buyer's Stamp Duty and ABSD in cash within 14 days, complete the private purchase (typically 10 to 12 weeks with a mortgage), then sell the flat within the ABSD refund window, claim the refund, and refund CPF.
• Bridge: sell the flat second, but borrow short-term against the expected sale proceeds to cover the gap between the condo's downpayment and the cash you actually have in hand today.

A worked illustration, arithmetic on a real guide's numbers, not a bank quote. A S$1.5 million condo, against an HDB flat valued at S$780,000 with no loan outstanding. Buyer's Stamp Duty is S$44,600 regardless of sequence. If the flat is sold first, the buyer needs 5% minimum cash of S$75,000 plus BSD, total cash at purchase of about S$119,600, and a 75% LTV tier on the new loan. If the condo is bought before the flat is sold, ABSD at 20% adds S$300,000, paid in cash and not from CPF, pushing total cash at purchase to about S$419,600. Where the flat still carries an HDB loan, the LTV tier on the new private loan drops to 45%, meaning a S$675,000 loan against S$1,125,000 owed on the purchase, with a downpayment of S$825,000 of which at least S$375,000 must be cash. The gap between S$119,600 and S$419,600 is the entire sequencing decision, priced.

The gap in buy-first is usually closed with a bridging loan, sized against what the flat's eventual sale will release: sale price, less the outstanding loan, less selling costs, less the CPF refund due. On the same S$1.5 million purchase, one illustration puts the shortfall between a 25% downpayment and cash in hand at S$275,000, costing about S$2,521 in interest at 5.5% over two months, or S$8,938 at 6.5% over six months if the sale drags. A bridging loan under MAS Notice 645 must be repaid within six months or it stops being a bridging loan for regulatory purposes and the carve-outs that come with that status fall away; lenders want a valid Option to Purchase on the new property and a signed contract on the property being sold before they will grant one at all, which means you cannot bridge a purchase before you have at least committed to selling. If the flat's sale falls through, one guide reports the bank may convert the bridge into a personal loan at rates exceeding 10 to 12% a year; another says it simply keeps accruing at the bridging rate until a new buyer completes. The two do not agree, and which one your bank does is a question to put to them in writing before you sign, not after.

Eligibility: what the Minimum Occupation Period actually locks

The standard Minimum Occupation Period is 5 years from legal completion, before which you cannot sell the flat, cannot buy or hold any private residential property, local or overseas, and cannot rent out the whole flat. Prime and Plus flats, and flats bought under the Fresh Start Housing Scheme, run a longer 10-year and 20-year MOP respectively, on the same restriction. A Singapore PR who is a flat owner must sell within 6 months of acquiring completed or uncompleted private residential property, local or overseas, a materially tighter deadline than the ABSD refund window a citizen gets, and one worth flagging early precisely because it moves against a PR household, not with it.

After MOP, a Singapore Citizen may buy private property and keep the flat: there is no ABSD remission for retaining it, so the second-property ABSD applies in full, and once you own private property, any later HDB purchase, if you ever want one, cannot use an HDB concessionary loan again. If you are selling and the timing between your flat's completion and the condo's completion doesn't line up, a seller who has committed to buy a completed property may arrange a temporary extension of stay in the sold flat of up to 3 months after resale completion, a private arrangement with the buyer, at a S$20 HDB fee, during which you pay non-owner-occupier property tax on the flat you no longer own but still occupy.

One route reported in market guides, not confirmed against HDB or IRAS wording: where the flat is owned by one spouse only, the spouse who owns no property buys the condo solely in their own name at 0% ABSD as a Singapore Citizen, while the HDB stays with the other spouse. This does not get around the MOP itself, which still requires both spouses to have fulfilled it before either acquires private property, and no primary source confirms this structure works as described. Get this checked by a conveyancing lawyer against your own household's facts before relying on it.

Citizenship status: who is treated as who

ABSD on a second residential property is 20% for a Singapore Citizen, 30% for a Permanent Resident, and 60% for a foreigner outside the Free Trade Agreement list; nationals of the United States, Switzerland, Liechtenstein, Norway and Iceland, and EFTA PRs, are taxed as citizens under their respective FTAs, obtained by remission application on the myTax Portal, not automatically. A US green-card holder who is not a US national does not qualify, the remission follows nationality, not residence, and a US citizen who also holds Singapore PR status is charged at the citizen rate under IRAS's own reading. An entity or trust buying pays 65% regardless of citizenship, which effectively rules out routing the new purchase through a company for tax reasons alone.

A married couple where at least one spouse is a Singapore Citizen and neither owns any residential property can buy the condo jointly with full ABSD remission on the second property, refunded once the flat is sold within 6 months of the purchase's completion, or of TOP/CSC if the condo is uncompleted, whichever applies. IRAS states plainly that it will not extend that six-month timeline, and the refund application is rejected outright if any condition is unmet. Where one spouse already owns the flat and the couple buys the condo jointly, the rate depends on the mix: an SC-SC couple pays 20%, an SC-PR couple pays 20% if the citizen owns the flat and the PR owns nothing, otherwise 30%, and an SC-foreigner couple pays 60%, with the second-property ABSD refunded only once the flat is disposed of, and never where either spouse would end up owning a third property. There is no married-couple remission at all for an SPR-foreigner couple.

Two guides disagree on whether a PR-PR couple's buy-first refund needs a citizen spouse specifically or accepts a PR spouse; IRAS's own married-couple remission document, as read for this page, requires at least one Singapore Citizen. A PR-PR couple upgrading should not assume a refund exists for them and should get IRAS's position in writing before committing to buy first on the strength of one.

Taxes: the sequencing tax, and the ones that don't move with it

Buyer's Stamp Duty, unaffected by sequence

BSD on the new condo is 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$1,500,000, and 6% above S$3,000,000, on the higher of price or valuation. On a S$1.5 million purchase that is S$44,600, and it is due whichever order you sell and buy in. It is the one tax on this page that sequencing cannot touch.

Additional Buyer's Stamp Duty, the tax sequencing exists to avoid

This is the number the whole sequencing question is actually about. Sell first and a Singapore Citizen upgrader pays no ABSD at all, because the flat is gone before the new purchase completes. Buy first and the same household pays 20% up front, in cash, refundable only if the flat sells inside the six-month window above. Guides disagree on when that six-month clock actually starts for a completed private purchase: one reads it from option acceptance, another from purchase completion, another from the private property's own completion, another from TOP or OTP exercise; only for an uncompleted purchase does everyone agree it runs from TOP or CSC, whichever is earlier. IRAS's own wording is simply 'date of purchase', and this page could not confirm which reading matches it. Get the actual start date from IRAS or your conveyancing lawyer in writing before you count down to it yourself.

Guides also disagree on how the refund is actually claimed once the flat sells: one law firm says submit to IRAS within 6 months of the old sale completing, with a refund in 4 to 8 weeks; another says apply within 6 months of the HDB sale; a third excerpt of IRAS's own wording describes the refund as automatic within 6 weeks of stamping the sale. This is not a rounding difference, it is a live-versus-passive process, and getting it wrong risks the same forfeiture the six-month deadline itself threatens. And the duty is not free to hold: IRAS pays no interest on ABSD held while you wait for the flat to sell, and two estimates from the same firm put the opportunity cost at roughly S$15,750 on S$300,000 held for 3.5 years at 1.5%, or about S$57,600 on S$360,000 held for four years at a 4% opportunity cost, depending entirely on which assumption you use.

Seller's Stamp Duty, mostly not your problem here

SSD does not touch the HDB flat you are selling to upgrade; the revised residential SSD regime taken effect 4 July 2025 explicitly does not affect HDB owners, because the Minimum Occupation Period already does that job. It becomes relevant only later, if you sell the new condo within four years of buying it: 16% in year one, 12% in year two, 8% in year three, 4% in year four, nil after, on the higher of price or market value. Sequencing this upgrade well now is also, in effect, buying yourself SSD-free flexibility on the condo for the next four years, because a rushed buy-first purchase under cash pressure is the kind of decision people later want to unwind early.

Property tax, and the flat you might keep

Owner-occupier property tax runs progressively from 0% on the first S$12,000 of Annual Value to 32% above S$140,000, but it applies to only one property you own and occupy; a second home you occupy, or any property you let out, including a flat you keep after upgrading, is taxed at the non-owner-occupier schedule: 12% on the first S$30,000 of Annual Value, 20% on the next S$15,000, 28% on the next S$15,000, 36% above S$60,000. A one-off 2026 rebate of 15% applies to an owner-occupied HDB flat and 10%, capped at S$500, to an owner-occupied private home; neither reaches a flat or condo you don't occupy yourself.

Keeping the flat and letting it out after you move into the condo is a separate decision from the sequencing this page covers, with its own tenant risk, void cost and landlord tax mechanics, and its own page.

Borrowing: the loan tier that actually decides the sequence

This is the mechanical reason buy-first is harder than it sounds for most households. With one housing loan still outstanding on the flat, a bank caps the new loan at 45% Loan-to-Value, meaning 55% down, of which at least 25% of the price must be cash, the balance from CPF Ordinary Account or cash. One law-firm guide calls buy-first practically impossible for most upgraders under this tier unless the HDB loan is already fully paid off, because the cash and CPF required at that lower tier, stacked on top of the ABSD above, is simply more than most households have sitting free. Selling first restores the ordinary 75% first-loan LTV tier on the new purchase, which is the other reason sell-first is the cheaper route, not just in stamp duty but in how much loan the bank will actually extend.

Total Debt Servicing Ratio caps all property borrowing at 55% of gross monthly income, assessed at a MAS floor rate of 4% for residential loans regardless of the rate actually quoted. On a S$2,000,000 condo at 75% LTV, a S$1,410,000 loan over 30 years runs about S$6,732 a month at that floor, needing roughly S$12,240 of gross monthly income with no other debt. The Mortgage Servicing Ratio, the tighter 30% cap, does not apply to a private condo at all, it reaches only HDB flats and ECs within MOP; once you're buying private, TDSR alone governs, which is a genuine simplification against the HDB loan you may be paying off.

Bridging loans sit outside TDSR while the outstanding balance is due for repayment within six months, on MAS's own reading of the exemption; two other guides describe banks running an internal stress test around 4.8% regardless of the stated exemption, and one flatly states a bank adds the stressed bridge repayment into the 55% TDSR ceiling anyway. This is unreconciled sourcing, not a settled rule, and it is exactly the kind of thing to get from your own bank in writing rather than infer from a comparison site. Reported bridging rates themselves vary widely by source, from roughly 2.5-3.0% a year in one law-firm guide to 4.88-6.5% a year across several bank-rate trackers, typically 3-month SORA plus a 3.5 to 4.5 percentage point spread; treat any rate quoted to you as your own bank's offer, not a market constant.

The two loans in this transaction sit on different rate structures by design, not by choice. A bridging loan is short, typically pegged to a bank's Prime Rate or to 3-month SORA plus a spread, with no lock-in, because it is meant to be gone within months. The new mortgage on the condo is a decades-long commitment, usually taken with a 2-year fixed or discounted-floating package and a prepayment penalty of around 1.5% inside the lock-in. Pricing the bridge as if it behaves like the mortgage, or the mortgage as if it can be unwound as freely as the bridge, is the most common way this financing goes wrong in practice.

Renovation and control: what you can actually change, and when

This is where control shows up on an upgrading page: not as a legal right but as a budget line you decide, unlike the tax and financing lines above. A condo renovation runs roughly S$24,800 to S$71,100 for a two-bedroom unit and S$32,200 to S$84,100 for a three-bedroom, with guides recommending a contingency buffer of 10 to 20% of the budget, higher again on a resale unit than a new one, because you don't know what's behind the walls until you open them. Whether to renovate the condo before or after moving in is genuinely yours to decide; whether to renovate the flat before selling it is a live but unverified claim in market guides, some claiming renovation lifts resale value by 15 to 30%, others warning that a large spend on a landed home is rarely recovered because a new owner with different taste simply replaces it. No guide gave a sourced, HDB-specific figure either way, so treat any agent's claim about renovation-to-sell as their opinion, not a number.

If the eventual plan is a landed upgrade rather than a condo, addition and alteration or a full rebuild is a materially larger and slower decision than anything above, and it has its own page.

Conveyancing: two transactions, two clocks, sometimes two lawyers

The HDB sale and the condo purchase are not one transaction with two ends, they are two separate legal processes that can overlap, and each has its own fees and its own clock. On the flat: an Option to Purchase runs 21 calendar days, HDB completion follows about 8 weeks after HDB accepts the resale application, and HDB arranges the CPF refund within 7 to 14 working days of the completion appointment, with any balance cash proceeds paid by cheque at that same appointment. On the condo, with a mortgage, expect roughly 10 to 12 weeks from the Option to legal completion. Private-property legal fees typically run S$2,000 to S$5,000 all-in; HDB's own in-house legal service, if you use it for the flat, is scaled at 13.5 cents per S$100 on the first S$30,000, 10.8 cents on the next S$30,000, and 9 cents thereafter, usually landing under S$1,000. [⚠ conveyancing.fee.hdb_inhouse_scale: sources differ; awaiting a ruling]

CPF mechanics compound the buy-first cash squeeze specifically. CPF cannot disburse before its own charge is registered on the new property, so a buyer commonly pays BSD and ABSD upfront in cash to meet the 14-day stamp duty deadline and applies for CPF reimbursement only afterward, once that charge is lodged. Stamp duty, legal fees and lodgment fees paid from CPF sit outside the CPF housing Valuation Limit and Withdrawal Limit calculation entirely, so using CPF for those does not eat into how much CPF you can put toward the purchase price itself, a distinction worth knowing before you assume CPF has run out.

Estate: what changes once you hold both, or neither

If the condo is held in joint tenancy, ownership passes automatically and in full to the surviving owner on death, outside the will and outside probate, the same rule that likely already applied to the flat. If you retain the flat after upgrading rather than selling it, changing how it's held, joint tenancy to tenancy-in-common or the reverse, needs every co-owner's agreement, a S$50 non-refundable fee, and a signed Instrument of Declaration; it is a live decision worth revisiting once the household's asset mix has actually changed, not something to leave as it was set at first purchase.

One insurance point that sits squarely on this page and nowhere gentler: the Home Protection Scheme tied to an HDB loan covers HDB flats only. The day you upgrade to a condominium or EC, HPS cover ends, and if the new private mortgage is larger than the flat's ever was, as it usually is, a larger loan can be left with no life cover behind it at all unless you arrange a private mortgage insurance or term policy before, not after, the condo loan is drawn down. HPS does not replace income for survivors or pay ongoing living expenses even while it is in force; it only clears the loan.

The twelve questions: what this upgrade actually is, in plain terms

Two questions sort you before the twelve do, and neither is 'are you buying to invest or to live in it', nobody upgrades believing the condo will fall in value, so that question sorts nobody. The two that matter: are you borrowing to buy, and once you hold the condo, are you lending it out or living in it? Almost every household on this page is borrowing, that is the entire reason sequencing and LTV tiers matter here at all. If the flat is kept and let out after the move, that flat becomes a yield play, positive carry by construction, rent coming in against no mortgage if it's paid off, or a smaller one if not. The condo itself, financed and lived in, is negative carry by construction: the mortgage goes out every month and no rent comes in against it, a fact rarely said out loud by a household mid-upgrade and focused entirely on the sale price.

C0, the play. Upgrading from a flat is overwhelmingly a balance-sheet play: you are converting home equity built in the flat, much of it CPF, into a larger, more leveraged equity position in the condo. It is not a cash-flow play at the point of purchase; whatever cash-flow position you end up in, positive if you keep and let the flat, negative if you don't, is a consequence of the balance-sheet decision, not the reason for it.

C1, balance sheet. What you owe changes sharply: an HDB loan, if any, is discharged or absorbed, and a private mortgage of up to 75% of a materially larger price appears in its place, or up to 75% again if you sell first and reset the LTV tier, less if you don't. What you own changes from a flat with a use-restricted, government-priced resale market to a condo with an open private market, a different asset entirely, not simply a bigger version of the same one.

C2, cash flow. What actually moves, and when, depends entirely on sequence. Sell-first: sale proceeds and CPF refund in, at completion; downpayment, BSD and legal fees out, weeks later, at the condo's own completion. Buy-first: BSD and ABSD out in cash within 14 days of the condo purchase, bridging interest out monthly until the flat sells, sale proceeds and CPF refund in only once that sale actually completes, and the ABSD refund in, weeks to months later, once IRAS processes it. The funding gap in buy-first is precisely the S$275,000-to-S$419,600 range the worked example above prices; in sell-first, there is functionally no gap, only a waiting period with no cash committed.

C3, P&L. Profit is not the same as cash, and this upgrade is where that distinction bites hardest, not on an annual rental statement but on a single purchase. The 'profit' on selling the flat, sale price minus what you originally paid, looks real and often is, but it is not the cash you actually have on the day the condo completes if you bought first: that cash position is sale proceeds minus outstanding loan minus CPF refund minus ABSD already spent minus bridging interest paid, several of which are still unknown numbers on the day you sign the condo's Option.

C4, carry. Income minus financing cost, and on the condo itself, if you live in it, that number is structurally negative: no rent, one mortgage. If the flat is kept and let out, its own carry is separately positive, rent minus whatever's left on its loan, and whether the household's combined position nets to positive or negative carry depends on that flat's rental yield against the condo's mortgage rate, an arithmetic exercise worth doing before deciding to keep the flat rather than sell it, not after.

C5, give and get. What you give: a materially larger, more leveraged debt position, a stamp-duty bill in the tens or hundreds of thousands depending on sequence, and, if you buy first, a hard six-month deadline you do not control the courts or the resale market to guarantee. What you get: a private, unrestricted asset with none of the MOP, EIP or income-ceiling constraints the flat carried, and, for most households on this page, more space and a materially different lifestyle, which is the actual reason 13,480 of them are doing this in 2026 and not a spreadsheet reason at all.

C6, exposed to. The private property market between your Option date and your completion date, which can move against you over the 10-to-12-week gap; the resale market for the flat, if you bought first, which decides whether the six-month ABSD clock is met at all; interest rates on both the bridge and the new mortgage, priced on different benchmarks and reset on different schedules; and, if this is a joint purchase across citizenship or residency status, an ABSD rate that can change materially depending on facts, such as which spouse owns what, that a lawyer needs to get right before the Option is even exercised.

C7, for how long. The MOP already committed you to 5 to 20 years on the flat before you could sell it at all; the condo purchase commits you to a mortgage that will typically run 25 to 30 years, and to Seller's Stamp Duty if you sell it within four years of buying. This is not a short-horizon decision at any point in the sequence, including the bridging leg, which is the only genuinely short-dated instrument in the whole transaction, by law capped at six months to keep its favourable treatment.

C8, the failure cascade, in the order it actually runs. If you bought first and the flat does not sell inside the ABSD refund window, or inside the bridge's six-month term, the first hit is cash flow: bridging interest keeps accruing, potentially at a converted personal-loan rate exceeding 10 to 12% a year, while you hold both properties. That accrual moves into the year's P&L as a real loss, not a paper one. If the flat's price has to be cut to force a sale within the deadline, or if the ABSD refund is refused because a condition was missed, that loss can tip into negative equity on the combined position. Negative equity on an asset you cannot sell fast without a further discount is illiquidity. Illiquidity that forces you to keep paying two loans you cannot service from income alone is insolvency. Every step here follows from the step before it, and every one of them starts from the same root cause: buying before selling, without a firm, priced answer for what happens if the sale slips past six months.

C9, liquidity. The flat is the more liquid of the two assets in this transaction while HDB resale demand stays where it is; the condo, once bought, is illiquid to you specifically because Seller's Stamp Duty penalises selling it within four years and you have just spent everything you have on the downpayment. If you need to raise cash fast during the upgrade, before the flat sells, the only lever available is the bridging loan itself, and it is a loan, not liquidity in any other sense, it has to be repaid from the same sale you are already waiting on.

C10, control. This is the page's own version of the clothes tax, financing and legal wear elsewhere on this site: you control the sequence and the timing of the sale within the limits above, and you control what you spend on renovating the condo once it's yours, but you do not control how fast the HDB resale market clears, how fast the bank processes your CPF reimbursement, or whether IRAS's ABSD refund reading matches the one your lawyer used to set your deadline. Sequencing is the one lever this page is entirely about, because it is the one thing genuinely inside your control.

C11, the exit. Selling the condo later costs SSD if inside four years, agent's commission on the way out, and the same conveyancing process this page describes for the flat, run again in reverse. There is no forced-exit mechanism here, unlike a compulsory-acquisition landed scenario elsewhere on this site; your exit is a private sale, on a private timeline, and the sequencing discipline this page argues for at entry is exactly what determines how much cash, versus how much debt, you are exiting with whenever that day comes.

The professionals this sequencing problem actually employs

An upgrade like this is not one transaction, it is at least two conveyancing files, one or two mortgage applications, frequently a bridging-loan application, and a stamp-duty filing with a refund claim behind it, each billed separately. A mortgage broker earns a referral commission from the bank on the new loan, paid on disbursal, not by you, and disclosed under MAS rules; that is a genuine free service to you if the broker is actually shopping multiple banks rather than defaulting to the one that pays best. A bridging lender earns interest whether or not the sequencing was the cheapest available option for your household, which is precisely why the sizing formula above, and the six-month deadline, deserve independent arithmetic before you sign, not the lender's own worked example.

Where I sit: I do not lend, I do not place bridging loans, and I do not file ABSD refund claims. What I can do is lay out the sequence, the deadline, and the cash gap in one place before you talk to the bank, the bridging lender and the two conveyancing lawyers separately, each of whom sees only their own slice of this transaction. A mortgage broker, bridging specialist or conveyancing lawyer with a real practice in HDB-to-private upgrades can reach me through work with me. I have no referral terms to publish here, and I will not invent any.

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

This upgrade can pay an agent twice: 1 to 2% of the flat's resale price, market convention, on the sale side, and, on the purchase side, either a resale commission of about 2% split by co-broke, or nothing at all from you if the condo is a new launch, where the developer pays the buyer's agent directly, typically 2 to 3% of price. CEA sets no fixed rate for any of this; commission is negotiable, and almost 8 in 10 consumers know it, with 85% of those who negotiated succeeding in lowering it. Pay the agency, never the individual salesperson, and read the Prescribed Estate Agency Agreement before signing; an exclusive agreement runs up to three months and you stay liable for commission on that flat even if you sell it yourself or through another agent inside that window.

Where the incentive points, including against the agent's own client. An agent representing you on the flat is paid only when it sells, and paid faster and with less marketing effort if you accept an earlier, lower offer, which pushes toward selling first, urgently, exactly the sequence this page's own arithmetic already recommends on tax grounds, so the two interests happen to line up for a citizen household with no other complications. They line up less well for a household where buy-first is genuinely the right call, for example where the flat's resale market is thin or the ABSD-refund arithmetic clearly favours locking in the condo now: an agent paid only on the flat has no commission reason to walk you through a buy-first bridging structure at all, because it doesn't touch their fee, and one agent may never collect commission from both sides of the same transaction, a boundary worth knowing before assuming the same person is advising you on both legs.

Median agent income is reported around S$72,000 a year, with new agents at S$10,000 to S$40,000 in their first year, figures worth holding against the size of the commission a single upgrade transaction like this one generates for the agent involved, before deciding how much weight to put on their sequencing advice specifically.
