The 15-month wait-out period, which required private property owners to wait after selling before buying a non-subsidised HDB resale flat, has been removed. Interest in million-dollar flats surged immediately (Singapore Property, 22 August 2026).
That timing matters. The wait-out was a cooling measure aimed at one specific group, private owners downgrading into the resale market, and its removal reopens that demand channel now rather than on a delay. Buyers who sell a private property this quarter can be bidding on a resale flat the same quarter.
None of the financing rules moved. The Mortgage Servicing Ratio still caps HDB repayments at 30% of gross monthly income, bank loans are still limited to 75% loan-to-value (LTV), and HDB concessionary loan eligibility still carries an income ceiling plus conditions on prior private ownership that many downgraders will not clear.
So the contest at the top of the resale market is now between two buyers with very different constraints. The financed buyer is bound by MSR and LTV. The downgrader arrives with sale proceeds and can decide how much of the price to borrow at all. That asymmetry, not the headline price, is what a financed buyer needs to plan around, because it determines how much you should borrow and how large a cash buffer you need to hold.
The two sets of numbers on a S$1.1m flat
Assume a purchase price of S$1,100,000, a 25-year tenure, an illustrative bank rate of 2.6% per annum for the actual repayment, and the MAS stress rate of 4% for the affordability check. Assume also that the buyer holds the remaining 25% in cash and CPF and has met all HDB eligibility and Additional Buyer's Stamp Duty (ABSD) conditions.
A financed buyer at the full 75% LTV borrows S$825,000. At 2.6% over 300 months, that is S$3,743 a month. Stressed at 4%, it is S$4,355. Dividing the stressed figure by the 30% MSR cap gives a minimum gross household income of S$14,517.
Now the downgrader. Injecting S$700,000 of sale proceeds leaves a loan of S$400,000. At 2.6%, that is S$1,815 a month. Stressed at 4%, S$2,111, which clears MSR on a gross household income of S$7,037.
Same flat, same rules, less than half the income needed to qualify.
What this changes at the offer stage
Two things. First, work out your MSR ceiling before viewing, not after a failed offer. The stressed repayment, not the actual one, is what decides whether the loan exists.
Second, budget for cash over valuation separately. A bank lends against the lower of price or valuation, so any COV is paid in cash on top of the 25% downpayment. On a S$1.1m flat that downpayment is S$275,000, plus S$28,600 in Buyer's Stamp Duty at standard IRAS rates. A downgrader with proceeds in hand absorbs a S$30,000 COV without touching their loan quantum. A buyer at the LTV ceiling does not have that option, which is the practical reason to leave headroom below your maximum rather than bid to it.
