Singapore’s property cooling measures are not one rule but a set of checks on demand, leverage and short-term resale. For a buyer, the practical questions are straightforward: how much stamp duty is payable, how much can be borrowed, how much income can support the loan, and whether any holding or wait-out period affects the plan.
This guide focuses on the rules in force now rather than attempting a complete policy timeline. That distinction matters: Additional Buyer’s Stamp Duty (ABSD), Seller’s Stamp Duty (SSD) and HDB eligibility rules depend on a buyer’s profile and, in some cases, the date of acquisition. Always confirm the position before exercising an Option to Purchase.
ABSD: the buyer profile can change the entire budget
ABSD is payable on top of Buyer’s Stamp Duty. Under the current IRAS ABSD rates, the duty is calculated on the higher of the purchase price or market value.
| Buyer profile | First property | Second property | Third and subsequent property |
|---|---|---|---|
| Singapore Citizen | 0% | 20% | 30% |
| Singapore Permanent Resident | 5% | 30% | 35% |
| Foreigner | 60% | 60% | 60% |
Entities generally pay 65%, while housing developers are subject to a separate framework: 35% that may be remitted if conditions are met, plus a 5% non-remittable component. A residential property transferred into a living trust is generally charged ABSD (Trust) at 65% upfront, with a possible refund where the statutory conditions are satisfied.
Two details regularly upset otherwise sound budgets. First, even a partial or joint interest generally counts as a property. Second, joint buyers with different profiles are generally charged the highest applicable rate on the whole property. A Singapore Citizen buying a first home with a foreign spouse should therefore not assume the citizen’s 0% rate automatically applies. Remissions exist for certain married couples and qualifying treaty nationals, but eligibility and deadlines must be checked with IRAS rather than assumed.
Sequence also matters for an upgrader. If a citizen still owns one home when acquiring the next, the new purchase is normally a second property for ABSD purposes. Selling first may produce a different result. Buyers comparing both routes should model the duty, temporary accommodation and completion risk before committing.
SSD now discourages a four-year exit
SSD is a seller’s cost, but it should be considered before buying because it can make an early exit expensive. For residential property acquired on or after 4 July 2025, the IRAS SSD schedule is 16% when sold within the first year, 12% in the second, 8% in the third and 4% in the fourth. No SSD is payable after more than four years.
For property acquired from 11 March 2017 through 3 July 2025, the earlier three-year schedule remains relevant: 12%, 8% and 4% across the first three years, with no SSD after more than three years. The acquisition date therefore determines which schedule applies; the latest table should not be applied retrospectively to every owner.
SSD is based on the higher of the selling price or market value. A buyer who may relocate, change household size or need liquidity should treat the applicable holding period as a real constraint, not a minor transaction charge. Our report on the 2025 SSD increase and its anti-flipping purpose provides more context.
LTV limits determine the upfront funds required
Loan-to-value (LTV) limits cap the share of a property’s value that can be financed. The MAS current macroprudential settings place bank housing loans for individuals at up to 75% for a first housing loan, 45% for a second and 35% for a third. Here, “first”, “second” and “third” refer to the number of outstanding housing loans, not simply the number of homes ever purchased.
The limit is 20 percentage points lower if the tenure exceeds 30 years — or 25 years where the property is an HDB flat — or if the loan extends beyond age 65. That produces possible limits of 55%, 25% and 15% respectively. Banks can still lend less after assessing creditworthiness, income and the property valuation.
HDB housing loans currently have an LTV ceiling of 75%. In either market, an LTV ceiling is not the same as a guaranteed loan. Buyers also need funds for the downpayment, any cash-over-valuation, stamp duties and legal fees. ABSD does not raise the property value against which the bank calculates the mortgage.
TDSR and MSR test monthly affordability
LTV answers how much of the property may be financed; the Total Debt Servicing Ratio (TDSR) answers whether the borrower’s income can support the debt. The current TDSR threshold is 55% of gross monthly income. It covers the new mortgage together with other monthly debt obligations, including car loans, personal loans and credit facilities.
Financial institutions also assess the property loan using regulatory interest-rate assumptions rather than relying only on an attractive promotional rate. As a result, a lower advertised mortgage rate does not necessarily increase the approved loan dollar for dollar.
For loans used to buy HDB flats and executive condominium units directly from developers, the Mortgage Servicing Ratio (MSR) is capped at 30% of gross monthly income. MSR looks at the mortgage payment, while TDSR considers total debt. Where both apply, a household must satisfy both. Existing debt can therefore become the binding constraint even when the buyer has enough cash for the downpayment.
The 15-month HDB wait-out was removed, but the 30-month rule remains
A major current-rule change arrived in July 2026. Private residential property owners and former owners buying a non-subsidised HDB resale flat without an HDB housing loan are no longer subject to the 15-month wait-out period, according to the MND and HDB announcement. A current private-property owner using this route must dispose of local and overseas private residential property within six months after completing the HDB resale purchase.
This is a targeted relaxation, not the end of all wait-out rules. The existing 30-month period after disposal remains for those seeking a subsidised flat, including a new HDB flat with or without grants or a resale flat with grants; an executive condominium bought from a developer; or an HDB housing loan. Buyers can read our analysis of who may benefit from the removal of the 15-month rule, but should use their HDB Flat Eligibility letter to confirm their own route.
A practical checklist before exercising the option
- Confirm the ownership count: include partial and joint interests, and check every buyer’s citizenship or residency profile.
- Price both stamp duties: calculate BSD and ABSD on the higher of price or market value, then identify the SSD schedule tied to the acquisition date.
- Separate cash from borrowing: apply the correct LTV tier, allow for valuation shortfalls and keep transaction costs outside the mortgage estimate.
- Run both income tests: account for every recurring debt under TDSR and, where relevant, MSR.
- Check the housing pathway: grants, an HDB loan or a developer EC can preserve a 30-month wait even though the old 15-month rule has been removed for a narrower group.
- Recheck before signing: cooling measures can change, while liability is often fixed by the transaction date and documents executed.
The broad policy direction is consistent: discourage speculative turnover, moderate investment demand and keep household leverage prudent. For an individual buyer, however, the result depends less on market slogans than on four facts — buyer profile, existing loans, intended holding period and the exact HDB or private-home pathway.
