Every measure below changed a specific rule on a specific date. None have been reversed outright once the trigger for tightening (foreign capital, household debt, an overheated resale market) passed — the closest thing to a genuine easing was the March 2017 SSD shortening, and even that was undone in July 2025. Read chronologically, the pattern is a ratchet: measures tighten in response to a hot market and rarely loosen back to where they started.
The timeline
Interest Absorption Scheme and interest-only housing loans removed
Developers could no longer offer to absorb a buyer's mortgage interest during construction, and interest-only loans for property purchase were disallowed.
Who it affected: buyers of uncompleted private projects relying on deferred-payment financing.
Source: MAS, 14 Sep 2009 →Seller's Stamp Duty introduced; loan-to-value cut to 80%
A new Seller's Stamp Duty applied to residential property sold within 1 year of purchase. The loan-to-value ceiling for housing loans dropped from 90% to 80%.
Who it affected: short-term flippers and highly leveraged buyers.
Source: MAS, 20 Feb 2010 →SSD holding period extended to 3 years; second-property LTV tightened
The Seller's Stamp Duty holding period was extended from 1 year to 3 years, and the loan-to-value limit was lowered for buyers with an existing outstanding housing loan.
Who it affected: investors taking on a second mortgage.
Source: MAS, 30 Aug 2010 →SSD extended to 4 years; LTV cut further
The SSD holding period was extended to 4 years, with rates as high as 16% in the first year. The LTV limit was lowered to 60% for individuals with an existing outstanding housing loan, and to 50% for non-individual (company) buyers.
Who it affected: medium-term investors and corporate buyers.
Source: MAS, 14 Jan 2011 →Additional Buyer's Stamp Duty introduced
ABSD applied for the first time: a flat 10% for foreigners and non-individual buyers, with lower rates phased in for Permanent Residents and Singapore Citizens buying additional residential properties.
Who it affected: foreign buyers most directly, and PR/SC investors buying beyond their first home.
Source: MAS, 8 Dec 2011 →ABSD raised; minimum cash down payment doubled
ABSD rates rose by 5 to 7 percentage points across buyer profiles. Loan-to-value limits were tightened for buyers with an existing outstanding loan, and the minimum cash down payment for a second or subsequent housing loan rose from 10% to 25%.
Who it affected: PRs buying their first home (now liable for ABSD) and SC investors going for a second property.
Source: MAS, 12 Jan 2013 →Total Debt Servicing Ratio framework introduced
Lenders were required to cap a borrower's total monthly debt obligations, including the new loan being applied for, at a set share of gross income before granting any property loan.
Who it affected: every future borrower. This is the most structural measure on the list — a permanent affordability ceiling rather than a one-off tax at the point of purchase.
Source: MAS, 28 Jun 2013 →SSD holding period shortened to 3 years; TDSR eased for conservative refinancing
The SSD holding period was cut from 4 years back to 3, with rates lowered by 4 percentage points at each tier. Separately, the TDSR threshold was removed for mortgage equity withdrawal loans at 50% loan-to-value or below.
Who it affected: sellers inside the 3-4 year mark, and owner-occupiers refinancing at conservative leverage. The only meaningful easing in this entire timeline, later reversed in 2025.
Source: MAS, 10 Mar 2017 →ABSD raised for foreigners and entities; LTV cut across the board
ABSD for foreigners rose to 20% and for non-individual entities to 25%. Loan-to-value limits were cut by 5 percentage points for every housing loan, effective for options to purchase granted on or after this date. Rates for Singapore Citizens and PRs were also raised in the same round.
Who it affected: foreign and corporate buyers most directly, and every buyer taking a new mortgage regardless of profile.
Source: MAS, 6 Jul 2018 →ABSD hiked again; TDSR cut to 55%; HDB loan LTV cut to 85%
ABSD rates rose by 5 to 15 percentage points, with first-property purchases by Singapore Citizens and PRs left unchanged. The TDSR threshold tightened from 60% to 55%. The HDB loan LTV limit dropped from 90% to 85%.
Who it affected: investors moving to a second or third property, and HDB loan borrowers at the margin.
Source: MAS, 16 Dec 2021 →15-month wait-out introduced; interest rate floors raised; HDB loan LTV cut to 80%
Private property owners and former owners selling and downgrading to a non-subsidised HDB resale flat had to wait 15 months before they were eligible to buy. HDB introduced a 3% interest rate floor for computing HDB loan eligibility. MAS raised the medium-term interest rate floor used by banks to compute TDSR and MSR by 0.5 percentage points. The HDB loan LTV limit was cut from 85% to 80%.
Who it affected: retirees and downgraders moving from private property into HDB resale, and HDB loan borrowers.
Source: MAS/MND/HDB, 30 Sep 2022 →Foreign-buyer ABSD doubled to 60%
ABSD for foreigners rose from 30% to 60%. Singapore Citizens buying a second property saw their rate rise from 17% to 20%.
Who it affected: foreign capital head-on, and Singaporean upgraders and investors buying a second home.
Source: MAS, 27 Apr 2023 →HDB loan LTV cut to 75%; Enhanced Housing Grant raised
The loan-to-value limit for HDB housing loans dropped from 80% to 75%, matching bank loans. The Enhanced CPF Housing Grant for lower- and middle-income first-timers rose by up to $40,000 for families and $20,000 for singles.
Who it affected: HDB loan borrowers took a smaller maximum loan, offset for eligible first-timers by a larger grant.
Source: MND, 20 Aug 2024 →Seller's Stamp Duty holding period restored to 4 years; rates raised
SSD reverted to the pre-2017 4-year holding period, with rates raised by 4 percentage points at every tier (up to 16% in year one), for property purchased on or after this date.
Who it affected: short-term sellers and sub-sale flippers of uncompleted units — the stated trigger was a jump in short-holding-period transactions.
Source: MAS, 4 Jul 2025 →15-month wait-out period removed
The wait-out imposed in September 2022 was lifted with immediate effect for private property owners and former owners buying a non-subsidised HDB resale flat, provided the purchase is in cash or with a bank loan (an HDB loan remains off-limits for this group).
Who it affected: retirees and downgraders moving from private property into HDB resale — the friction point the 2022 measure created is gone. ABSD, MOP, and the HDB loan restriction itself are unchanged.

Every date and figure above is drawn from a MAS, MND or HDB press release, linked at the entry. Two details are worth flagging rather than presenting as equally solid as the rest: the exact loan-to-value figure for the August 2010 round is stated in general terms above because the primary release text could not be pulled in full at the time of writing (only corroborating secondary coverage and the release's existence were confirmed); and the July 2018 entry omits the specific Singapore Citizen and PR rate figures for the same reason — the foreigner, entity and LTV figures shown were directly confirmed, the SC/PR figures were not, so they have been left out rather than guessed.

Frequently asked questions
When did Singapore start using property cooling measures?
The current cycle began on 14 September 2009, when the Interest Absorption Scheme and interest-only housing loans were removed. Seller's Stamp Duty followed in February 2010 and Additional Buyer's Stamp Duty in December 2011.
What is the most recent Singapore property cooling measure change?
The most recent change is the removal of the 15-month wait-out period on 28 July 2026, which had required private property owners to wait 15 months before buying a non-subsidised HDB resale flat. Before that, Seller's Stamp Duty was extended back to a 4-year holding period with higher rates on 4 July 2025.
Which cooling measure has had the most lasting effect?
The Total Debt Servicing Ratio framework, introduced 28 June 2013, is the most structural of the measures. It caps a borrower's total monthly debt obligations against gross income for any property loan, and unlike a transactional tax it permanently governs loan eligibility rather than applying only at the point of purchase.
