Every right-sizer used to face the same problem: sell the condo, then sit out 15 months before you were allowed to buy a non-subsidised HDB resale flat, renting or bunking with family in between. That problem is gone. What has replaced it is a different, more manageable one: a 6-month disposal clock once you buy. Here is how to sequence the move properly.
Step 1: Confirm you actually qualify for the new track
The cash-or-bank-loan track only applies to a non-subsidised HDB resale flat. It does not extend to a BTO flat, a Sale of Balance Flats unit, a resale flat bought with a CPF housing grant, or an Executive Condominium bought from a developer. Any of those still sit under the older 30-month wait-out, and taking an HDB housing loan for any flat purchase also falls back under that same 30-month rule. If your plan is genuinely a non-subsidised resale flat, financed with cash or a bank loan, you are on the fast track with no wait at all.
Step 2: Decide the order — buy first or sell first
This is the decision that actually changed on 28 July 2026. Before the removal, most right-sizers had no real choice: you sold, then waited 15 months, so selling first was the only sequence that made sense. Now both orders are genuinely available.
Buy first, then sell within 6 months
You secure the resale flat you actually want in a market where good units move quickly, move in on your own timeline, and then have 6 months to dispose of the condo. ABSD is remitted upfront on the HDB purchase on the condition that you complete the private property disposal inside that window. The risk sits entirely on the sell side: if your condo does not transact within 6 months, in a market that is not always liquid on your schedule, you either accept a lower offer to make the deadline or face the ABSD clawback plus interest on the remitted amount.
Sell first, then buy
You bank the sale proceeds, refund CPF with accrued interest, and shop for the resale flat with cash in hand and zero deadline pressure. The cost is a period of interim housing, rental or otherwise, between the two transactions. With the 15-month wait gone, that interim period is now measured in weeks or months to find the right flat, not 15 months waiting out a rule.
Step 3: Work out the CPF refund
Whichever order you choose, when the condo sells you must refund to your CPF Ordinary Account the CPF principal you withdrew for it, plus the accrued interest that money would have earned had it stayed in your CPF. This refund is not optional and it happens before any cash proceeds reach you. For owners who have held the property a long time or withdrew a large sum, the accrued interest component can be a meaningful chunk of the sale price, so model it before you count on a specific cash figure for the next purchase.
Step 4: Line up financing — cash or bank loan only
The new track is unavailable to HDB loan applicants. If your financing plan for the resale flat depends on an HDB concessionary loan, you are automatically on the 30-month track regardless of whether you have already sold your private property. Get pre-approved for a bank loan before you commit to a flat, since bank loan eligibility, loan-to-value limits, and TDSR assessment all differ from HDB loan terms, and a financing gap discovered after you have signed is the worst possible time to find it.
Step 5: Get your HDB Flat Eligibility (HFE) letter
An HFE letter from HDB is required before you can commit to a resale purchase as a private property owner. Apply for this early in your process rather than after you have found a flat, since it confirms your eligibility track, financing option, and any conditions upfront.
Step 6: Complete the purchase and calendar the disposal deadline
If you bought before selling, the 6-month clock starts from the resale flat's completion date, not from your offer date. Put that date in your calendar the day you complete, and start marketing your condo before that date rather than after it, so a slow sale does not force a distressed price in month five.
The full cost stack to plan for
| Cost | When it hits | Note |
|---|---|---|
| CPF refund + accrued interest | On condo sale completion | Reduces your net cash proceeds; not payable to HDB |
| Seller's Stamp Duty (if applicable) | On condo sale completion | Depends only on your condo's holding period, unrelated to this rule change |
| Buyer's Stamp Duty on the resale flat | On resale flat purchase | Standard BSD scale applies to the resale flat price |
| Agent commission, legal fees | Both transactions | Standard transaction costs on each side |
| ABSD clawback + interest (if disposal misses 6 months) | Only if the condo is not sold in time | Avoidable with realistic sale timeline planning |
The verdict: a Money, Timing & Safety read
- Money: STRONG No more 15 months of rental or bridging costs between the two transactions, and ABSD is remitted upfront if you sequence correctly.
- Timing: MIXED You gain flexibility on which transaction goes first, but the buy-first path replaces open-ended waiting with a firm 6-month deadline that needs active management.
- Safety: MIXED The ABSD remission is conditional, not automatic. A condo that does not sell within 6 months turns a tax break into a tax bill plus interest.
Before picking a sequence, run a Money, Timing & Safety self-assessment against your actual condo's likely time-to-sell, and check how the flat type and town you are eyeing compares on our HDB rental yield ranking if a rental fallback matters to your plan. For the financing side specifically, our HDB loan vs bank loan guide and current ABSD rates guide are worth reading before you commit to either sequence.
Who this suits
Right-sizers with a liquid, well-priced condo
If your condo is realistically saleable within 6 months at a price you would accept, buy-first removes the interim housing problem entirely. Our right-sizing in retirement guide covers the broader decision of whether downsizing suits your position at all.
Owners in a slower-moving segment or uncertain about timing
If you are not confident your condo sells within 6 months, sell-first removes the ABSD clawback risk entirely, at the cost of some interim housing. Our guide to owning HDB and condo simultaneously covers what changes if you decide to hold both longer than planned.
Frequently asked questions
Should I sell my condo first or buy the HDB resale flat first?
Buying first now works because the 15-month wait is gone: you lock in the flat you want, move when ready, and you have 6 months from the resale purchase's completion to dispose of your private property. Selling first still suits owners who want zero overlap risk and are comfortable renting briefly while they hunt for the right flat. There is no longer a timing reason to default to sell-first; the choice comes down to your risk tolerance for selling under a 6-month clock.
Can I use an HDB loan to buy the resale flat after selling my condo?
No. The removed 15-month wait-out only applies if you finance the resale flat with cash or a bank loan. Private property owners and former private property owners still cannot take an HDB housing loan for a non-subsidised resale purchase; that track still carries the older 30-month wait-out.
Will I pay ABSD if I buy the HDB flat before selling my condo?
Not upfront, provided you commit to disposing of your private property within 6 months of the resale flat's completion. ABSD is remitted at the point of purchase on that condition. If the private property is not sold within the 6-month window, the remitted ABSD plus interest becomes payable.
What happens to the CPF I used on my condo?
When you sell your private property, you must refund the CPF principal you withdrew for it plus the accrued interest it would have earned had it stayed in your CPF Ordinary Account, before that money is released to you in cash. This refund goes back into your CPF OA, not to HDB, and it directly reduces your usable cash proceeds from the sale.
Does the removed wait-out period change my Seller's Stamp Duty exposure?
No. Seller's Stamp Duty on your private property sale depends only on how long you have held it, unrelated to the wait-out period. If you are inside the SSD holding period window, that cost applies regardless of this rule change and should be included in your net proceeds calculation before you commit to a purchase.
Planning the sell-condo, buy-HDB move?
The right sequence depends on your condo's actual liquidity, your CPF position and your financing eligibility. A Property Portfolio Analysis runs the real numbers against your holding period and cash position, with no incentive to push you toward buying first or selling first.
