Checked against official guidance on 20 September 2026. This guide covers moving from an HDB flat to a private condo. A new executive condominium has separate eligibility and disposal rules. Confirm your own eligibility, tax treatment and financing with HDB, IRAS, CPF Board, your lender and conveyancing lawyer.
Which sequence fits your household?
Selling first is usually the more manageable starting point if your condo purchase depends on the HDB proceeds. It gives you a firmer budget, but you may need temporary accommodation. Buying first can secure a particular home and reduce moving disruption, but only works if you can fund the overlap without assuming a quick sale or a tax refund.
- Sell first: establish the sale price, loan redemption and CPF refund, then confirm the cash and usable CPF available for the next purchase. Budget for rent, storage and a second move if the dates do not align.
- Buy first: secure financing and funds for deposits, taxes and both properties before signing. Stress-test a slower sale and a lower selling price.
- Coordinate both: work backwards from the two completion dates with your lawyer. A signed sale does not mean the proceeds are already available.
Check the HDB restrictions before committing
Check your actual Minimum Occupation Period and flat conditions in MyHDB. HDB lists a five-year MOP for unclassified/Standard resale flats and ten years for Plus/Prime resale flats. Restrictions cover acquiring private residential property, not just selling the flat. Citizenship and flat type also affect whether you can retain the HDB after buying privately; an all-SPR household must notify HDB before exercising the private property's OTP and is subject to disposal requirements. Do not assume every household can keep both homes.

Buying first: do not assume ABSD will be refunded
A temporary overlap can create ABSD exposure. Ask your lawyer to establish the applicable ownership count, buyer profiles and acquisition/disposal dates before you exercise an OTP.
The married-couple concession requires a joint purchase in both spouses' names only, with at least one Singapore citizen. Other conditions include each spouse owning no more than one residential property at purchase, paying ABSD first, remaining married, keeping ownership of the replacement unchanged and acquiring no other residential property in between.
- Completed condo: the first property must be sold within six months of the second property's purchase date.
- Uncompleted condo: the six-month sale period runs from TOP or CSC, whichever is earlier.
The refund application deadline is six months after sale; qualifying declared cases may be refunded automatically. Have your lawyer confirm the process. Listing your HDB is not a sale, and these tax dates are not simply moving-day dates. A single buyer should not assume this married-couple concession applies.

Separate cash proceeds from CPF refunds
Your selling price is not your spendable cash. Deduct the outstanding housing loan, CPF principal used and accrued interest, and sale costs. CPF refunds return to CPF accounts, not your bank account. The amount available for another home depends on the applicable CPF rules, including age and retirement requirements.
For owners aged 55 or above, retirement-account requirements can affect how much refunded CPF remains available for housing. Obtain the actual refund figures and usable balances; do not count the same refund as both cash proceeds and purchase funding.

Worked example: enough overall, but not necessarily on time
Illustrative assumptions, not a loan offer or client result: an HDB sells for $700,000; outstanding loan is $250,000; CPF refund is $200,000; sale costs reserved are $20,000. The owners have another $50,000 cash. Assume the full $200,000 CPF refund is confirmed usable for their next home after it arrives.
- Cash from sale: $700,000 − $250,000 − $200,000 − $20,000 = $230,000.
- Cash after adding existing savings: $230,000 + $50,000 = $280,000.
- Total cash and usable CPF after sale: $280,000 + $200,000 = $480,000.
Now assume a $1.5 million condo with a lender-confirmed $1.125 million loan. The price balance is $375,000. Add an illustrative $60,000 reserve for BSD, legal costs, moving and other purchase costs, excluding any ABSD: total funds needed are $435,000. This leaves $45,000 before ABSD, renovation and any costs exceeding that reserve. Replace every assumption with your own quotes and confirmations.
If a $75,000 deposit is paid toward that $375,000 price balance, the remaining price balance is $300,000. The deposit is counted once. Before the HDB sale, however, the household has only $50,000 cash in this example: even that assumed deposit is $25,000 short. The eventual $480,000 does not solve an earlier payment deadline.
This example does not determine the permitted loan or minimum cash contribution. The bank must confirm both, taking existing housing loans and the borrowers' circumstances into account. Our affordability calculator can help frame an initial discussion; its HDB resale cash-readiness tool is not a private-condo approval assessment.
Build the timeline around money and keys
- Before committing: confirm MOP, an achievable selling range, CPF refund figures, lender assessment and tax position.
- Before exercising the purchase OTP: list each deposit, stamp-duty and completion payment with its due date and funding source. Ask your lawyer to confirm when sale cash and CPF can actually be used.
- Before agreeing completion dates: arrange accommodation, renovation access, storage and a fallback if either transaction slips.
- After sale: reconcile actual cash/CPF receipts and complete any applicable remission steps within the required time.
HDB permits a temporary extension of stay of up to three months after resale completion, subject to its conditions and the buyer's agreement, where the seller has committed to buy a completed property in Singapore. It is not an automatic entitlement or a solution for waiting years for a new launch.

Test a delay before you sign
Run the plan again with a lower HDB sale price, a delayed completion and higher temporary housing costs. For a new launch, allow for progressive payments and a later handover. If the plan needs a bridging loan, ask the lender for eligibility, costs and repayment conditions before relying on it. If ABSD remission is essential, treat meeting every condition as a separate requirement, not a promised inflow.
Check recent HDB resale prices and condo transaction data before setting the budget. Browse new launches only after deciding whether your move needs a completed home.
