Wait-Out Period: Sell Condo, Buy Resale HDB
Selling your condo and going back to HDB? The wait is shorter than BTO — but there's still a mandatory period. Here's the breakdown.
Answer: 15 months after disposal of your private property. Clock starts from completion/transfer date. Exemption: if you're 55+ and buying a 4-room or smaller resale flat, no wait required.
How the 15-Month Wait Works
After disposing of a private residential property (condo, landed, or overseas), you must wait 15 months before buying a resale HDB flat. This is HDB's Private Property Owners (PPO) condition for resale purchases.
- • Start date: Date of completion / legal transfer of private property
- • Not: Date you listed, signed OTP, or exercised option
- • Duration: 15 full months from disposal
- • Applies to: All applicants and essential occupiers listed in the application
15 Months (Resale) vs 30 Months (BTO)
| Factor | Resale HDB | BTO / SBF / Open Booking |
|---|---|---|
| Wait-out period | 15 months | 30 months |
| 55+ exemption | Yes (4-room or smaller) | No |
| Time to move in (after wait) | ~3 months | 3–5 years |
| Total time (sell to move in) | ~18 months | 5–7+ years |
| Price | Market rate | Subsidised |
| Income ceiling | None (for purchase) | $7,000–$14,000 |
Resale is faster by about 15 months on the wait alone, plus you skip the BTO construction wait.
55+ Exemption: No Wait Required
If you're 55 or older and buying a 4-room or smaller resale flat, the 15-month wait-out period does not apply. You can buy a resale HDB immediately after disposing of your private property.
| Condition | Requirement |
|---|---|
| Age | 55 years old or above |
| Flat type | 4-room or smaller (2-room, 3-room, 4-room) |
| 5-room or executive | Exemption does NOT apply — 15-month wait still required |
| BTO | Exemption does NOT apply — 30-month wait still required |
Buying Resale HDB While Still Owning Private
You can buy a resale HDB while still owning a private property — but you must dispose of the private property within 6 months of the resale HDB purchase completion. This gives you a window to overlap ownership.
- • Deadline: 6 months after resale HDB completion
- • Consequence: Failure to sell = HDB can compulsorily acquire your flat
- • ABSD: You may need to pay ABSD upfront (refundable upon disposal)
Timeline Example
| Event | Date (Example) |
|---|---|
| Condo sale completed | Jan 2026 |
| 15-month wait-out ends | Apr 2027 |
| Start viewing resale flats | Apr 2027 |
| Complete resale purchase | ~Jul 2027 |
From condo sale to moving into a resale HDB: roughly 18 months. Factor in interim housing during the wait.
Other Eligibility Requirements
Beyond the wait-out period, you still need to meet standard HDB resale eligibility:
- • Singapore Citizen (at least one buyer)
- • Family nucleus (married couple, parent + child) or Single scheme (35+)
- • No income ceiling for purchase (but grants have income limits)
- • Not currently owning another HDB flat

FAQ
How long must I wait after selling my condo to buy a resale HDB?
You must wait 15 months from the date of disposal (completion/transfer) of your private property. This is shorter than the BTO wait-out period, which is 30 months.
When does the 15-month clock start?
The clock starts from the date of completion or legal transfer of your private property — not the date you listed, signed the OTP, or exercised the option. HDB uses the official completion date.
Is there an exemption for older buyers?
Yes. If you are 55 years old or above and buying a 4-room or smaller resale flat, the 15-month wait-out period does not apply. You can buy immediately after disposing of your private property.
Do I need to sell my condo before buying a resale HDB?
You can buy a resale HDB while still owning a private property, but you must dispose of the private property within 6 months of the resale HDB purchase. Failure to do so means HDB can compulsorily acquire the flat.
What is the difference between the 15-month and 30-month wait?
The 15-month wait applies to resale HDB purchases. The 30-month wait applies to BTO, Sale of Balance Flats (SBF), and open booking. If you need a flat sooner, resale is the faster path.
