A concurrent purchase happens when a buyer signs OTPs on multiple residential properties before any disposal. ABSD is assessed per property in chronological order of OTP exercise; once one OTP is exercised, all subsequent purchases are counted as 2nd/3rd properties at higher ABSD rates. There is no remission for concurrent purchases by SCs or PRs unless the matrimonial-home conditions are met for one of the disposals within 6 months.
Concurrent purchases are rare but high-stakes — typically arising when a buyer wants to secure two properties (e.g., for separated occupancy, family use, or portfolio strategy) without selling the existing primary residence. The ABSD math gets aggressive fast.
For a married SC couple already owning one matrimonial home, exercising two OTPs the same week triggers: 1st new purchase = 2nd property (20% ABSD), 2nd new purchase = 3rd property (30% ABSD) — total ABSD = 50% of the combined purchase prices. No matrimonial remission for the 3rd-property OTP.
Three structural rules:
Counting is by OTP exercise sequence — If OTPs are exercised on the same day, IRAS treats them as sequential based on timestamp on each Sale and Purchase Agreement. The first becomes "2nd property," the second becomes "3rd property" for ABSD count.
Matrimonial remission applies to one OTP only — If selling the existing matrimonial home within 6 months, the remission applies only to the OTP designated as replacing it. The other OTP carries permanent higher-bracket ABSD.
Decoupling alternatives — Some couples decouple existing ownership (one spouse releases share to the other) so each spouse can then purchase a "first property" — this is heavily scrutinised by IRAS post-2023 and requires bona-fide substance.
Property upgrade paths are as much about timing and tax as they are about price. The wrong sequence can trigger ABSD on both properties simultaneously; the right sequence can defer stamp duty legally and preserve CPF usage. This guide walks through the key milestones, decision points, and common pitfalls, and links out to the calculators you will need to stress-test the numbers at each step.

Concurrent Property Purchase: ABSD Implications & Timing
This guide covers the key financial and practical considerations for concurrent property purchase: absd implications & timing.
Key Considerations
- Check your eligibility and any MOP restrictions
- Calculate your total costs including stamp duties and legal fees
- Plan your financing — CPF, cash, and mortgage options
- Consider the timeline and temporary housing needs
- Consult a property agent experienced in upgrade transactions
Concurrent purchase example: married SCs, owning 1 matrimonial HDB, OTPing 2 condos same week:
| Property | Price | ABSD Category | ABSD Rate | ABSD Outlay |
|---|---|---|---|---|
| Condo A (OTP exercised first) | S$1.5M | 2nd property | 20% | S$300,000 (refundable if matrimonial HDB sold within 6 months) |
| Condo B (OTP exercised second) | S$1.2M | 3rd property | 30% | S$360,000 (NOT refundable) |
| Total ABSD | S$2.7M | — | — | S$660,000 (S$360K permanent) |
Compare to sequential: buy Condo A first (claim matrimonial remission, sell HDB), then buy Condo B as 2nd property (claim remission again only if disposing of Condo A as new matrimonial home — usually impractical). Net: concurrent purchases trap couples in higher-bracket ABSD permanently.

- Avoid concurrent purchases unless economically essential. The permanent higher-bracket ABSD on the second OTP is usually larger than the cost of sequencing properly.
- Engage a tax-aware conveyancing lawyer. For any genuinely concurrent purchase, get written tax structuring advice before signing OTPs.
- Consider decoupling carefully. Decoupling existing ownership to "reset" ABSD count is real but requires bona-fide substance; IRAS scrutinises mechanical / artificial decouplings.
- Time OTP exercise strategically. If proceeding with concurrent, exercise OTP on the higher-value property first to maximise the matrimonial remission benefit.

Frequently Asked Questions
What is the single biggest mistake in upgrading?
Should I sell first or buy first?
Can I keep my HDB as a rental while upgrading?
Does signing OTPs the same day count as one transaction for ABSD?
No. ABSD count is per-property, by OTP-exercise sequence. Even identical timestamps are treated as sequential per IRAS practice.
Can I claim matrimonial remission on both concurrent purchases?
No. The matrimonial remission applies once — to the OTP designated as the replacement matrimonial home. The other concurrent purchase is permanently in the higher bracket.
Is buying with separate names a workaround?
One spouse purchasing one property in their sole name, the other spouse purchasing the other in theirs, can sometimes achieve two "1st property" treatments — but only if neither spouse owns existing residential property and bank financing accepts the structure. Get tax advice.
