Question 1

How long does it take to buy a resale HDB flat?

Accepted Answer

From starting your search to collecting keys, a resale HDB purchase typically takes about three to five months. Most of that is the resale process itself: once the Option to Purchase is exercised, the buyer and seller submit the resale application on the HDB Resale Portal, HDB takes up to about 28 working days to accept it, and processing through to the completion appointment runs roughly eight weeks more. The single most variable part is finding a flat and agreeing a price, which can take anywhere from a couple of weeks to a few months. The HDB stages are largely fixed and cannot be fast-tracked.

Question 2

How long after selling my condo can I buy a resale HDB flat?

Accepted Answer

If you are under 55, you must wait 15 months after the sale of your private property is legally completed before you can buy a non-subsidised resale HDB flat. The wait-out extends to 30 months if you need an HDB loan or a CPF housing grant. The clock starts on the legal completion date of the sale — not the day you found a buyer or exercised the option — so the full move, including selling and the later purchase, commonly spans well over a year. Buyers aged 55 and above who are right-sizing to a four-room or smaller flat are exempt from the wait-out. This rule was in effect as of May 2026; the government has signalled it is under review, so verify the current position before planning.

Question 3

When is stamp duty due after I exercise the OTP?

Accepted Answer

Buyer's Stamp Duty — and Additional Buyer's Stamp Duty, if it applies — is payable within 14 days of exercising the Option to Purchase. The 14-day countdown begins on the date you exercise. If the purchase document is signed overseas, the deadline is 30 days from when it is received in Singapore. Late payment carries IRAS penalties that escalate the longer it goes unpaid. In most transactions your conveyancing lawyer handles the e-stamping, but the deadline is fixed regardless of who pays.

Question 4

How long is an Option to Purchase valid?

Accepted Answer

For a resale HDB flat, the OTP is valid for 21 calendar days — the buyer must exercise within that window or it lapses. For private property, the option period is typically 14 to 21 days, set by agreement between the parties. If a buyer does not exercise within the validity period, the option lapses and the option fee is generally forfeited to the seller. Because the window is short, buyers should have financing lined up before accepting an OTP.

Question 5

How long does it take to sell a property and receive the proceeds?

Accepted Answer

Plan for roughly three to five months from listing to cash-in-hand, though finding a buyer is the unpredictable part. Once the buyer exercises the OTP, completion is typically eight to twelve weeks away for private property, while an HDB sale runs through the resale application and completion appointment over a similar period. The cash you receive on completion is the sale price after the outstanding loan is redeemed and the CPF you used is refunded to your CPF Ordinary Account with accrued interest — so the proceeds reach you at completion, not when the buyer signs.

Question 6

If I buy my next home before selling my current one, when must I sell to reclaim my ABSD?

Accepted Answer

Buying before selling means you briefly own two properties, so ABSD is charged in full on the new purchase and paid upfront. To reclaim it under the remission for a married couple's matrimonial home, you generally must sell the first property within six months of the new purchase's completion, where the new property is already completed. For an uncompleted new launch, the window is tied instead to the issue of TOP or CSC. You must be able to float the ABSD in the interim — it can be a very large sum — and the refund is claimed from IRAS after the sale completes.

Question 7

How long does a CPF refund take after I pay stamp duty in cash?

Accepted Answer

On a resale purchase, BSD usually has to be paid in cash first because there is not enough time to draw down CPF within the 14-day deadline. If you have sufficient CPF Ordinary Account savings, the amount can then be reimbursed to you — your conveyancing lawyer typically submits the reimbursement around legal completion, once the property is in your name. The cash refund is generally released within roughly one to four weeks of completion depending on processing. Note that ABSD cannot be paid from CPF at all; it must be settled in cash. Because the refund is not instant, keep a cash buffer for the period around completion.

Question 8

How do progressive payments work on a new launch or BTO?

Accepted Answer

An uncompleted new launch or BTO is paid in stages rather than all at once. After the booking fee and signing the Sale & Purchase agreement, payments fall due as each construction milestone is certified — foundation, reinforced concrete framework, brick walls, roofing and ceiling, car park and so on — with the home loan drawn down in step, so interest is charged only on the amount disbursed. A larger instalment is due at TOP, when keys are handed over, and the final instalment at CSC, usually about a year later. The whole timeline commonly runs two to four years from booking to completion.
