Can I keep my HDB and buy a second property?
Yes, you can keep your HDB flat and buy a second property, but only after you have met the Minimum Occupation Period — 5 years for standard flats, 10 years for Plus and Prime flats. If you are a Singapore Citizen, the second residential property attracts 20% Additional Buyer's Stamp Duty. Plus and Prime flats also bar whole-flat rental.
The full rules
Keeping your HDB and buying a second property
Two things decide whether you can do this: your flat's Minimum Occupation Period (MOP), and the Additional Buyer's Stamp Duty (ABSD) on the second property.
Minimum Occupation Period
| Flat type | MOP | Extra conditions |
| Standard flats | 5 years | — |
| Plus and Prime flats | 10 years | No whole-flat rental at any time; subsidy clawback on first resale |
You must complete the MOP before you can own a second property while keeping your flat. Plus flats (from Oct 2024 BTO exercises) and Prime/PLH flats (from 2021) carry the longer 10-year period.
Additional Buyer's Stamp Duty on your second property
| Buyer profile | Second residential property |
| Singapore Citizen | 20% |
| Permanent Resident | 30% |
| Foreigner | 60% |
| Entity | 65% |
ABSD is charged on the purchase price or market value, whichever is higher.
> Nationals of the USA, and nationals/PRs of Switzerland, Iceland, Liechtenstein and Norway, are treated as Singapore Citizens for ABSD under free trade agreements.
Confirm your MOP completion date and eligibility with HDB before you commit.
Worked example
Worked example
Sarah is a Singapore Citizen who bought a standard BTO flat. She has lived in it for 5 years, so her MOP is met.
She now wants to buy a private condominium at $1,500,000 as her second property while keeping her flat.
| Item | Amount |
| Purchase price | $1,500,000 |
| ABSD rate (Citizen, 2nd property) | 20% |
| ABSD payable | $300,000 |
Because she has completed the 5-year MOP, she can keep her flat and buy the condo — but she must budget $300,000 in ABSD on top of the price and other costs.
What this means for you
Citizen who just got the keys
If you have owned your standard flat for less than 5 years, you cannot keep it and buy a second property yet. Wait until your 5-year MOP is complete.
Plus or Prime flat owner
Your MOP is 10 years, not 5. You also cannot rent out the whole flat at any time, and a subsidy clawback applies on your first resale. Plan around the longer timeline.
PR household
Once your MOP is met, a second residential property attracts 30% ABSD. Check your purchase eligibility with HDB before proceeding.
