Selling a condo to buy an HDB flat: the rules, the order and the money
You can buy a non-subsidised HDB resale flat first and sell the condo within six months, with no wait-out, provided you do not take an HDB loan. The move frees the difference between the condo's net proceeds and the flat's price. Part of that goes back to your CPF as a housing refund; the rest is cash you can turn into a monthly income.
The rules that decide the order
- No wait-out for a non-subsidised resale flat bought with a bank loan or cash (since 28 July 2026).
- Six months to complete the sale of the private property after the flat purchase completes.
- 30 months of waiting if you want an HDB loan, a CPF housing grant, a new flat from HDB or a new EC.
- Five-year minimum occupation period on the flat you buy (ten years for Plus and Prime flats) before you can sell it, rent out the whole flat, or buy private property again.
Where the money goes when the condo sells
From the sale price come the outstanding loan, the agent's fee and legal costs. Then the CPF you used for the condo, with the accrued interest, goes back to your CPF accounts as a housing refund. What is left is cash. The flat's price is paid from that cash and CPF, and whatever remains is the sum that can pay you.
If you are 55 or older, you may be able to add a Silver Housing Bonus of up to $30,000 per household by right-sizing to a 3-room or smaller flat and committing up to $60,000 to your CPF Retirement Account; the private property must have an annual value of up to $31,000 (the bonus is smaller above $21,000). See the Silver Housing Bonus guide.
A worked example
A couple in their late fifties sell a condo for $1,600,000 with $200,000 of loan left, and buy a 4-room resale flat for $650,000 with cash from the sale. Costs of selling come to about $35,000. Their CPF used for the condo, with accrued interest, is $420,000, which returns to their CPF.
| Sale price | $1,600,000 |
| Less the loan | $200,000 |
| Less selling costs | $35,000 |
| Net proceeds | $1,365,000 |
| Of which back to CPF | $420,000 |
| Cash | $945,000 |
| Less the flat, and its stamp duty and fees (about) | $670,000 |
| Cash left to put to work | about $275,000 |
Figures are illustrative. Freedom Age runs the same arithmetic on your own numbers, then shows the age at which the freed sum, your CPF and any rent can pay the monthly income you want.
When not to do it
If the condo is under three years old in your hands, seller's stamp duty applies. If you need an HDB loan, the 30-month wait returns, and with it a long spell of renting. And if your goal is income rather than space, keeping the condo and renting it out can beat selling; the answer turns on the rent, the loan left and your age.

Questions people ask
- Do I need to sell my condo before buying an HDB flat?
- No. Without an HDB loan you can buy the resale flat first and must complete the condo sale within six months of the flat purchase.
- Can I use my CPF to buy the HDB flat after selling my condo?
- Yes. The CPF refunded from the condo sale returns to your Ordinary Account and can be used for the flat, subject to CPF's usage limits.
- Do I pay ABSD if I buy the HDB flat before selling my condo?
- Not if any buyer is a Singapore citizen: IRAS fully remits ABSD on the acquisition of an HDB flat when the buyer or any joint buyer is a citizen, granted automatically on HDB's approval. A household of permanent residents pays ABSD at 5% on the flat.
- Is there a minimum occupation period on the resale flat?
- Yes. Five years for a Standard or older unclassified flat, ten years for Plus and Prime flats, before you can sell it or buy private property again.
