The 15-Month Wait Is Gone — and the Cooling Measure Just Became a Weather Report

Fifteen months is an awkward length of time. Too long to hold your life still, too short to build another one. It is a rented flat for five quarters, a school year that begins somewhere you did not plan to be, a set of boxes you decide not to unpack because what would be the point.

That was the arithmetic facing anyone who owned private property in Singapore and wanted to move into a resale HDB flat. From September 2022, they had to wait 15 months after disposing of their private home before they could buy a non-subsidised resale flat. The rule caught the retiree cashing out of a condo, the family whose finances had changed, the couple who had decided a flat in a familiar town beat a mortgage in a shinier one.

There was one door open. Citizens aged 55 and above could skip the wait — but only for a 4-room flat or smaller. If you were 54, or the flat you wanted had five rooms because your parents were moving in, the door was shut. You waited.

The wait-out period was never a judgement about downgraders. It was a brake, applied at a moment when the resale market was running hot enough to worry people.

In 2022, HDB resale prices were climbing at a pace Singapore had not seen in years, and a particular kind of buyer was in the mix: someone who had just sold a private property, arrived at a flat viewing with a great deal of cash and no mortgage constraint, and could out-bid a young family working to a bank's valuation. Cash-over-valuation was the language of the day. The 15-month wait was introduced in a package of cooling measures to take that buyer out of the queue for a while.

That is worth remembering now, because it tells you exactly what would have to change for the rule to go: not fairness, not lobbying, but the price line itself. Cooling measures are removed when the thing they were cooling has cooled.

Minister Chee's stated reason was that resale price growth had eased significantly since the pandemic. That is the sort of claim worth checking against the numbers rather than nodding along to — so we went to HDB's own official Resale Price Index, the same series the ministry watches.

It tells the story cleanly. The index peaked at 203.7 in 2025Q3, held flat at 203.6 through the end of that year, slipped to 203.4 in 2026Q1, and fell again to 202.8 in 2026Q2. That is a decline of 0.3% quarter-on-quarter, and it is the second consecutive quarterly fall. Year-on-year, the index is now essentially unchanged — a flat -0.0%.

For a market that spent the early 2020s climbing without pause, a flat year is a genuinely different weather system. The brake came off because the hill stopped.

Here is the full recent run of HDB's official Resale Price Index (2009Q1 = 100), which is HDB's own series and separate from URA's private index:

The shape is unmistakable: a steep climb through 2024, a plateau across 2025, and a gentle turn down in 2026. Nothing here is a crash — the index is still far above where it sat two years ago. But the momentum that justified a cooling measure is not in this chart any more.

The median prices tell the same story in dollars. Across all towns in 2026 H2, the national median 4-room resale flat is $628k, down 0.3% year-on-year. Every other flat type is also slightly softer than a year ago.

Because the wait-out period no longer caps the size of flat a former private owner can buy without waiting, the bigger flats matter more than they used to. This is the national picture:

Two things stand out. First, the softness is broad — not one flat type is up year-on-year. Second, look at the top of the table: executive flats at a $894k median, 5-room at $728k. These are exactly the flats that were previously off-limits without a wait to anyone under 55 coming out of private property, and they are the ones the change opens up.

These are medians across every town, so a specific flat in a mature estate with a long lease can sit well above them — and they are gross of the resale levy, agent commission and legal fees.

The headline says private property owners, which sounds like a story about the wealthy. The people it frees are more ordinary than that.

First, the under-55 right-sizer — someone at 48 or 52 whose children have left, whose condo maintenance fee has crept up, and who would rather own a flat outright than carry a mortgage into their sixties. Same logic as a 56-year-old, none of the exemption.

Second, anyone who needed more than four rooms. The old carve-out stopped at a 4-room flat, quietly excluding the multi-generational household, the family moving parents in, the household that needs a study. On our numbers those are $728k and $894k decisions, and they were unavailable without a 15-month pause.

Third, the ones caught mid-move — people who sold during the wait-out era and were counting down. Their clock has simply been switched off.

What this is not is an invitation to arbitrage. You still cannot use an HDB housing loan, and you must dispose of your private property within six months of completing the purchase. This is a rule for people moving house, not people adding one.

Yes. This change removed the waiting period, not the ownership rule.

If you buy a non-subsidised HDB resale flat as a private property owner, you must dispose of your private residential property — whether it is in Singapore or overseas — within six months of completing the flat purchase. You also cannot take an HDB housing loan for the purchase; it has to be financed privately.

So the sequencing has changed, not the destination. Previously you sold, then waited 15 months, then bought. Now you can buy first and sell within six months, which removes the interim-housing problem that made the old rule so disruptive. You still end up owning one home, not two.

Nobody can tell you this honestly, and be wary of anyone who does. What can be said is which way the forces point.

On the upward side: a pool of buyers who were legally sidelined can now bid, they are typically well-capitalised, and the change opens flat types that were previously closed to them. On the downward side: the index has fallen two quarters running and every flat type is softer year-on-year, which suggests supply and affordability limits are doing real work — and the ministry only removed the measure because those forces looked durable.

The most likely shape is not a market-wide jump but a segment-level one. If you are shopping for a 5-room or executive flat in a mature town, you should expect more competition than you would have faced last quarter. If you are buying a 3-room in a non-mature estate, this change has very little to do with you. And if prices do run again, the honest historical lesson is that the measure that was just removed can be reintroduced.

The policy details — the removal of the wait-out period, the 28 July 2026 effective date, the previous age-55-and-4-room-or-smaller exemption, the six-month disposal requirement and the no-HDB-loan condition — come from the reporting of Minister Chee Hong Tat's announcement, linked below. Those are the reporters' facts, attributed rather than claimed as ours.

The price figures are ours. The HDB Resale Price Index (2009Q1 = 100) is HDB's own official quarterly series, which we read directly rather than re-derive. The median resale prices by flat type are our matched medians across HDB resale transactions for 2026 H2, national across all towns.

Three caveats matter. The HDB index is a separate series from URA's private index — compare them on direction, never level. The medians are a dated half-year snapshot across every town, so a specific block, storey or remaining lease can differ substantially. And the current half-year is excluded until enough resales lodge, because a partial window under-counts and would distort the figure.

• Mothership — No more 15-month wait-out period for private property owners who buy HDB flats: Chee Hong Tat, 28 July 2026.

The data:

• PropKaki median HDB resale prices by flat type, 2026 H2, national across all towns.

This is commentary written by the PropKaki Editorial Desk on reporting by CNA and Mothership. The account of what was announced belongs to those newsrooms; the price analysis, the framing and the opinions are ours.

It is opinion and general information, not financial, legal or property advice, and it is not a recommendation to buy or sell anything. Housing decisions turn on details we cannot see from an index — your income, your loan eligibility, the specific flat, the specific lease. Policy details can also be refined after an announcement, so check HDB's own published rules before acting on anything here.
