Sell the Condo, Buy the Flat, Skip the 15-Month Exile: One Couple's Right-Sizing, End to End

Mei Lin is 52, David 53. Their daughter graduated last year; the second bedroom of their 1,076 sq ft East-side condo has been a storeroom since. The mortgage still takes S$2,279 a month, the maintenance fund another S$385, and the question they had circled for two years — sell this and buy a five-room flat outright — always died on the same rock: until 28 July, selling would have exiled them from the HDB resale market for 15 months. Two moves, a rented flat in between, and a landlord's rent bill for the privilege of downsizing.

That rock is gone. MND removed the 15-month wait-out period with immediate effect on 28 July, for private owners buying a non-subsidised resale flat without an HDB loan. This article runs the couple's numbers end to end — sale, purchase, funding, and the monthly picture after — with every figure computed and every assumption stated.

The Tans are an illustrative composite, not clients. Prices, loan balances and CPF figures are stated assumptions; the maths on them is computed exactly.

What actually changed on 28 July

Under the old rule, a private owner (or anyone who had sold a private property in the past 15 months) could not buy a non-subsidised resale flat at all — the wait-out applied from disposal, and only sellers aged 55 and up buying a four-room or smaller flat were exempt. Mei Lin and David are 52 and 53, and they want a five-room. The exemption never covered them; the removal does.

The conditions that survive matter to the plan, so state them up front: the couple must not take an HDB housing loan (bank loan or cash only — the 30-month wait-out still applies to HDB-loan applications), they get no CPF housing grants, and the flat carries the standard 5-year minimum occupation period. They can even buy the flat first and sell the condo after, so long as the private property goes within six months of the flat purchase completing. The Tans choose the cleaner sequence — sell first, buy immediately after — which also spares them marketing a condo against a deadline.

The sale: where S$1.58 million goes

Assumptions: the condo sells at S$1,580,000 (about S$1,468 psf on 1,076 sq ft — mid-range for a 2000s-vintage East-side leasehold project); S$438,000 outstanding on the mortgage at 1.32% with 18 years left; S$320,000 owed back to their CPF Ordinary Accounts (S$246,000 principal drawn over the years plus S$74,000 of accrued 2.5% interest); a 2% agent commission plus GST; S$2,700 conveyancing.

Two things people routinely misread in that table. The CPF refund is not money lost — it lands back in their own Ordinary Accounts, earning 2.5% and fully usable for the next purchase; the accrued-interest line just stops compounding against them. And the S$438,000 loan repayment quietly cancels S$54,333 of future interest they would have paid over the remaining 18 years.

The purchase: a five-room flat, bought outright

Across July and August 2026, the median five-room resale in Tampines was S$791,500 over 126 transactions (the full range ran S$609,000 to S$1.12 million — floor, block and remaining lease spread that widely). The Tans agree at S$790,000, subject to the usual Request for Value after the OTP.

They fund it with the S$320,000 CPF refund plus S$556,200 of the sale cash. No loan of any kind — remember, the HDB loan is off the table under the wait-out removal's terms, and at their numbers a bank loan is optional, not necessary. (A borrower who preferred more liquidity could mortgage part of the flat at this month's 1.45% HDB fixed rates — that is a preference, not a requirement.)

After the dust settles: a five-room flat owned outright, S$228,656 still in cash, and their CPF Ordinary Accounts continuing to rebuild from salary contributions for the seven-plus working years each still expects.

The monthly picture

Before (computed on the stated assumptions, with property tax at the post-2025 owner-occupier schedule on an assumed S$34,800 annual value): S$2,279 mortgage + S$385 maintenance + S$76 property tax = S$2,740 a month. After (S&CC assumed at S$90 for a five-room; property tax on an assumed S$13,500 AV): S$95 a month. The delta is S$2,645 of monthly cash flow — S$31,700 a year — that stops leaving the household. For a couple whose retirement plan was long on home equity and short on everything else, that is the entire point of the exercise.

What the removal actually saved them

Run the counterfactual under the old rule. Sell in August 2026, then wait out 15 months before even applying to buy: an interim lease at an assumed S$3,800 a month is S$57,000 of rent, plus a second round of movers, plus whatever the resale market does to five-room prices while they wait — a market that has been easing, but never uniformly. The removal converts that into one move and back-to-back completions. It is the difference between a plan they kept postponing and one they executed in a quarter.

What they gave up

Honest ledger, because right-sizing is not free money. For the flat's 5-year MOP they cannot buy private residential property again, and the MOP blocks renting out the whole flat — the S$876,200 now in the flat is housing, not an investment position they can trade. They exit private-market exposure entirely: if condo prices resume climbing, they watch from a five-room. The S$228,656 buffer earns whatever they make it earn — at 2% it covers about S$380 a month of the household budget; at 0% in a current account it covers nothing. And a five-room in Tampines is not a 1,076 sq ft condo with a pool; part of the S$2,645 monthly saving is paid for in square feet and facilities.

Against that: no mortgage at 52, a S$228,656 liquid buffer where there was none, S$320,000 of CPF back at guaranteed interest, and a housing cost that a single part-time income could carry. The Tans' version of the trade is composite, but the machinery — the waterfall, the BSD tiers, the no-HDB-loan condition, the MOP — is exactly what any private owner walking this path this year will meet.

The Tans are an illustrative composite. Stated assumptions: condo sale price, outstanding loan, CPF principal and accrued interest, agent commission of 2% + GST, legal fees, renovation budget, interim rent of S$3,800, annual values of S$34,800 (condo) and S$13,500 (flat), and S&CC of S$90. Computed exactly on those assumptions: the proceeds waterfall, BSD of S$18,300 on S$790,000 under the IRAS marginal tiers, amortisation and interest figures, and property tax under the IRAS owner-occupier schedule.
