The 15-Month Wait-Out Rule: When Private Owners Can Buy a Resale HDB

If you own — or have ever owned — private residential property in Singapore and now want to buy a resale HDB flat, a cooling measure introduced in September 2022 makes you wait. The 15-month wait-out period catches downgraders and right-sizers moving from the private market back into public housing, and it surprises people who assumed selling their condo cleared the way. Here is exactly how it works and who escapes it.

What the rule actually says

Announced jointly by MND, HDB and MAS and effective 30 September 2022, the measure requires private property owners and former owners to serve a 15-month gap between disposing of their private property and buying a resale flat. It was introduced to moderate demand at the top of the resale market — private owners were increasingly outbidding first-timers, and the resale price index had been climbing for consecutive quarters. The government framed it as temporary, to be reviewed as the market cools.

Who it hits

The obvious group is people selling a condo to move into a resale HDB — a common right-sizing or cash-releasing move, especially for those coming out of an HDB-to-condo upgrade that didn’t work out, or investors unwinding a second property. It applies to ex-owners too, so having already sold doesn’t exempt you — the 15 months run from that sale. Note it bites on non-subsidised resale purchases; private owners generally don’t qualify for grants anyway, so this is their normal route.

The seniors exemption

There is one carve-out: Singaporeans aged 55 and above, and their spouses, are exempt when they move from private property to a 4-room or smaller resale flat. The exemption does not extend to 5-room or larger flats. It exists so that older households right-sizing for retirement are not forced to wait or to rent in between.

It sits on top of HDB’s standing rules

The wait-out is separate from — and additional to — the long-standing rule that an HDB owner cannot concurrently own private property, and must dispose of any private property within six months of buying a flat. Together they mean a private owner can neither hold both at once nor jump straight from one to the other.

How to plan around it

If a move from private to resale HDB is on your horizon, build the 15 months into your timeline — you may need interim rented accommodation, and the gap affects when you can commit to a flat. HDB has, in genuine-hardship cases, considered appeals, but you should plan on serving the full period rather than counting on a waiver. And because it is a temporary measure under review, check the current position before you assume it still applies to your situation.
