The 15-month wait-out period is gone: what private property owners buying an HDB resale flat need to know

For three and a half years, a private property owner who wanted to sell up and buy an HDB resale flat had to sit out 15 months after disposing of their private property before they could even apply. The rule was introduced in September 2022 as a cooling measure. It has now been removed.

What actually changed

Private residential property owners and former owners buying a non-subsidised HDB resale flat, without an HDB housing loan, are no longer subject to any wait-out period. You can dispose of your condominium and apply for a resale flat in the same month.

The Government gave two reasons. HDB resale prices have now fallen for two consecutive quarters — down 0.1% in 1Q2026 and 0.3% in 2Q2026 — and the supply of flats reaching their Minimum Occupation Period is rising steeply: about 8,000 units in 2025, 13,500 in 2026, 15,000 in 2027 and 19,500 in 2028. The measure had done its job.

What has not changed

This is where people are going to get caught out, so read this part twice. Three things survive the change:

1. The 30-month wait-out period still applies in full if you want to buy a subsidised flat (a new flat from HDB, or a resale flat with housing grants), buy an Executive Condominium directly from a developer, or take an HDB housing loan. If you need the HDB loan, you are still waiting 30 months.
2. You must still dispose of all your private residential properties — in Singapore and overseas — within six months of completing the HDB resale flat purchase.
3. You still need a valid HDB Flat Eligibility (HFE) letter before you can act. Existing valid HFE letters are unaffected, pending applications are updated automatically, and pending appeals against the old rule are now moot.

Who this actually helps

Three groups, in my experience of the calls I have taken this week.

Retirees and near-retirees monetising a private property. This was always the group the 15-month rule hurt most — people in their sixties who had a paid-off condominium, wanted to move to a resale flat near their children, and were told to find somewhere to live for 15 months first. That problem is now gone. Note that Singapore Citizens aged 55 and above buying a 4-room or smaller flat were already exempt; the change extends the relief to everyone, including those wanting a 5-room or larger flat. If you cancelled or narrowed an application because of the old rule, you can re-apply for a new HFE letter.

Families who over-extended into private property. If the mortgage stopped making sense — a rate reset, a job change, a divorce — the exit is now immediate rather than a 15-month limbo.

Owners of a single private property who want to hold cash. Selling a $2M condominium and buying a $700K resale flat releases capital that can no longer be trapped by a waiting period. Whether that is a good idea depends entirely on the numbers — see the caution below.

What to do about it

1. Check your Seller’s Stamp Duty exposure first. The date you bought decides everything — on or after 4 July 2025 puts you on the four-year clock at the higher rates.
2. Apply for or refresh your HFE letter. Nothing can proceed without it, and it takes time.
3. Model the sequencing. Selling first and buying second means you need somewhere to live in between; buying first means bridging finance and a six-month disposal clock. Neither is automatically right.
4. Check your CPF refund position. The CPF principal plus accrued interest goes back to your Ordinary Account on sale, not into your bank account. Plenty of people discover their "cash proceeds" are a third of what they assumed.
