HDB Says the Wait-Out Removal Changed Little. On Price It Is Right. On Volume It Is Not.

Alongside yesterday's third-quarter flash estimate, HDB offered its first public verdict on the policy it changed in July. Since the 15-month wait-out period for private property owners was removed on 28 July 2026, the board said, it "has not observed a significant increase in the prices and number of resale flats purchased by private residential property owners."

That is two claims, and the public transaction record answers them differently. On price, HDB is right: the segment a private downgrader would buy did not reprice. On number, the record pushes back — the share of large flats changing hands rose 2.76 percentage points in a single quarter, the sharpest second-to-third-quarter move in the ten years of data.

What the policy actually did

Before 28 July, a private property owner who wanted to buy an HDB resale flat had to sell the private property and then wait 15 months. The rule, introduced in September 2022, existed to keep cash-rich downgraders from bidding against first-time buyers. Removing it did not change any price, grant or loan limit. It changed one thing only: timing. A private owner can now sell and buy without parking themselves somewhere for over a year in between.

If that mattered, it would show up in a specific place. Downgraders coming out of a condominium or a terrace house do not buy two-room flexi flats. They buy the biggest thing the HDB market sells — five-room and executive flats. So that is where to look.

Price: HDB's claim holds

The five-room median moved $2,000 across the quarter in which the policy took effect — 0.3%, which is nothing. The executive median did not move at all. The all-flats median rose 1.3%, and HDB's own quality-adjusted index for the same quarter fell 0.2% to 202.4, which tells you the median rose on what was sold rather than on what flats are worth.

There is no price event here. Whatever happened in the third quarter, sellers of large flats did not get paid more for them.

Volume: the claim does not hold

Composition is a different story.

Large flats here means five-room, executive and multi-generation — the formats a downgrader buys. That share sat between 28.5% and 29.5% for fourteen consecutive quarters. In the third quarter of 2026 it jumped to 31.77%.

A 2.76-point move sounds small. In this series it is not. Here is every second-to-third-quarter change since the data begins:

It is more than double the next-largest move in ten years. The executive flat — the largest and oldest format HDB sells, and the clearest downgrader proxy — went from 375 transactions in the second quarter to 531 in the third, a 41.6% increase, taking its share of all resales to 7.16%. That is the highest executive share in fourteen quarters.

Two more things moved in the same direction. The median remaining lease on executive flats sold fell from 68.0 years to 66.1, meaning buyers reached further down the lease curve for size. And large flats went from 56.5% of all million-dollar resales to 59.1%, with 27.5% of every executive flat sold crossing $1 million, up from 24.8%.

Christine Sun of Realion Group, quoted yesterday, predicted exactly this shape: "Many private homeowners will be cash-rich after selling their homes and they are likely to buy large resale flats for the space and value." The composition data is consistent with her prediction and not with the volume half of HDB's.

Three reasons to not call this proof

This is where the honest version diverges from the convenient one.

The dataset cannot see who is buying. HDB's claim is specifically about flats "purchased by private residential property owners." The public resale file records month, town, flat type, block, storey, area, model, lease and price. It has no buyer field. Only HDB can test its own claim directly, and nothing below gets around that. What the public record can establish is whether the segment moved — and it did.

The monthly path does not line up with 28 July. Month by month, the large-flat share ran 29.55% in June, 31.52% in July, 29.68% in August, then 34.40% in September. July rose before the policy existed for all but three days of it, and August fell back to an ordinary number. If this were a clean policy effect you would expect a step in August that held. Instead the quarter's move is carried almost entirely by September. That is one month.

The level is not unusual by longer standards. 31.77% is a fourteen-quarter high, not a record. Large flats were 33% to 36% of the market routinely between 2017 and 2021. What happened in the third quarter is a return toward an older normal, not a departure into new territory — which is a reason to be careful about calling it a structural shift on one quarter of evidence.

One more caveat on the arithmetic: registered resale records continue to arrive after any given retrieval. Third-quarter volume stood at 7,416 records when this was computed, against the 7,528 transactions HDB published yesterday. September is the month still filling, and September is the month carrying the move — so the 34.40% figure is the least settled number here.

What to do with this

If you own private property and plan to downgrade, the removal of the wait-out gave you timing, not a discount. Large-flat medians did not move in the quarter after it was scrapped. The competition for those flats looks heavier than it did in the first half, so the risk is paying up in a bidding situation rather than missing a window.

If you are selling a five-room or executive flat, more of your format is trading than at any point in over three years, and more of it is crossing $1 million. That is a deeper buyer pool. It is not a higher price — the medians say otherwise, so price to recent comparables in your own block rather than to the headline.

If you are a first-time buyer looking at large flats, this is the segment where the mix shifted. One quarter is not a trend, but the direction is the one the 15-month rule was designed to prevent, and 23 October brings the full third-quarter statistics.

If you are reading that the policy changed nothing, that is right on price and incomplete on volume. The two halves of HDB's sentence are not equally supported.

Method

The HDB statement quoted is from the board's media release accompanying its flash estimate of the 3rd Quarter 2026 Resale Price Index, 1 October 2026, as reported by AsiaOne the same day, which also carries the Christine Sun quotation and HDB's published third-quarter transaction count of 7,528, up 5.2% year on year.

All price, volume, composition and lease figures were computed directly from the full register of 241,822 HDB resale transactions on data.gov.sg, January 2017 to October 2026, retrieved 2 October 2026. Quarters are calendar quarters on the month of registration. Registration trails the date a deal is agreed, and the file keeps receiving records after retrieval, so the most recent month is always the least complete — this pull returned 2,247 September records and 7,416 for the third quarter in total, against HDB's 7,528. "Large flats" means flat types 5 ROOM, EXECUTIVE and MULTI-GENERATION. Medians are unadjusted medians of recorded resale prices, not quality-adjusted index values; HDB's own index fell 0.2% to 202.4 in the same quarter, which is the figure to use for price direction and is published in HDB's Resale Price Index table. Remaining-lease medians are parsed from the dataset's remaining-lease field.

The 15-month wait-out period for private residential property owners buying HDB resale flats was introduced on 30 September 2022 and removed on 28 July 2026.
