The Complete Singapore Mortgage Guide 2026

Everything Singapore Citizens, Permanent Residents, upgraders, decouplers and refinancers need to know about buying, financing, refinancing and selling property in 2026. Written for buyers ready to act, not academics. Read end-to-end, or jump to your situation.

Part 1 — Get Loan-Ready

Every Singapore home loan clears the same set of regulatory gates before any bank releases funds. Master these five sections and you will know exactly how big a loan you can support and which lever to pull if the answer comes back smaller than you hoped.

1.1TDSR & MSR — Borrowing Capacity Caps

Two MAS-enforced ceilings cap every Singapore home loan. TDSR (Total Debt Servicing Ratio) caps total monthly debt at 55% of gross income — mortgage plus car loan, personal loans, credit-card minimums. MSR (Mortgage Servicing Ratio) caps the mortgage portion alone at 30% and applies only to HDB and Executive Condominium purchases.

On HDB purchases the 30% MSR almost always binds before the 55% TDSR. On a S$15,000 gross household income with no other debt, the MSR ceiling sets the qualifying instalment at roughly S$4,500/month — which sizes to about a S$945,000 loan on a 25-year tenure at the MAS 4% stress floor. Variable-income buyers face haircuts on bonuses and commissions before TDSR is computed.

1.2MAS 4% Stress Test

MAS Notice 645 forces every Singapore bank to stress-test loan eligibility against a 4% per annum medium-term interest rate floor, regardless of the rate you actually contract. In 2026 with fixed packages starting from 1.40% and 1M SORA at ~1.14%, this means your eligibility is sized against a number 2.6 to 3 percentage points higher than what you will actually pay.

The stress is real money. A buyer pre-qualified at today's 1.40% fixed might believe they can support a S$1.5M loan, then discover at IPA stage that the 4% floor caps eligibility at S$900K. Plan the purchase around the stressed instalment, not the headline rate.

1.3LTV Mechanics — HDB and Bank Loan Aligned at 75%

Since the 20 August 2024 cooling measures, both HDB concessionary loans and bank loans cap at 75% LTV on a first residential property. The alignment ended the HDB loan's historical LTV advantage. To preserve the 75% cap, two conditions must hold: loan tenure ≤ 25 years on HDB (30 years on private), AND loan must mature by borrower's age 65. Cross either trigger and LTV drops to 55% — meaning 45% cash/CPF down at completion.

For joint borrowers the IWAA (Income-Weighted Average Age) determines the trigger. Stretching tenure to lower the monthly often costs more in additional cash than the monthly savings recoup over the loan life.

1.4Self-Employed Income — the 30% Haircut

MAS Notice 645 forces banks to apply a 30% income haircut on self-employed earnings before TDSR is computed. A sole proprietor with S$200,000 annual notional income is treated as having S$140,000 for borrowing capacity. The two-year Notice of Assessment average is the typical reference. Recovery levers: pledge funds (100% / 48 months), show funds (30% / 48 months), or refinance with a banked income period after the business stabilises.

1.5CPF Ordinary Account Mechanics

CPF Ordinary Account funds the non-cash portion of the down payment, can service monthly instalments, and accrues at 2.5% per annum monthly compounded on every dollar withdrawn for housing. The accrued interest must be refunded to OA on sale — alongside the principal. On a 10-year hold using S$200K from OA, the refund obligation is approximately S$256K (P + I). Plan CPF usage deliberately because the refund mechanic transforms cash proceeds into restricted OA balance.

Part 2 — Buy Your First Property

Singapore offers four primary first-purchase routes: HDB BTO, HDB resale, Executive Condominium, and private (condo or landed). The financing rules, timelines and cash positions differ materially. Pick the route that matches your income, household composition, and 5-10 year property plan.

2.1First-Time HDB Buyer Walkthrough

The HDB Flat Eligibility (HFE) letter is mandatory before any OTP. Processing takes 21-30 working days. The HFE letter validates scheme eligibility, income ceiling for HDB loan, and grant eligibility (EHG, CHG, PHG). Plan: apply HFE on the My Flat Dashboard the moment you decide to buy — in parallel, apply IPA for bank loan if income exceeds the HDB ceiling.

2.2HDB Loan vs Bank Loan

HDB concessionary loan: 2.6% p.a. (CPF OA + 0.10%), no lock-in, no MAS 4% stress, eligible only with at least one Singapore Citizen and household income within the S$14,000 ceiling. Bank loan: from 1.40% p.a. fixed in 2026, full MAS 4% stress, 2-3 year lock-in. Both cap at 75% LTV post-Aug 2024. HDB loan permits zero cash down (full 25% can be CPF OA); bank loan requires minimum 5% cash.

2.3Best Home Loan for First-Time Private Buyer

First-time private buyers in 2026 typically pick between 2-year fixed (~1.40%) for cashflow certainty and 1M-SORA-pegged floating (~1.14% currently, trending up) for rate flexibility. The 75% LTV on a S$2M condo means S$500K down (S$100K minimum cash + S$400K CPF/cash). BSD of ~S$69,600. ABSD 0% for Singapore Citizen first property. Variable-income and self-employed buyers benefit most from independent multi-bank IPA scans.

2.4New Launch (BUC) Financing

Building-Under-Construction purchases use the Normal Payment Scheme: 5% booking, 15% on S&P signing, then staged drawdowns at construction milestones over 42-54 months until CSC. The bank disburses progressively, charging interest only on drawn portion. Monthly instalments rise stage by stage. By TOP (~month 42), the full instalment kicks in. Model the TOP-month cashflow now, not the day-one one.

2.5Executive Condominium — 10-Year MOP Reset

On 8 May 2026 MND doubled the EC Minimum Occupation Period from 5 to 10 years, raised first-timer quota to 90% with a 2-year priority window, and scrapped the Deferred Payment Scheme. Applies to ECs from Government Land Sales sites with tender closing on or after 8 May 2026. Existing ECs and the 5 pre-rule projects keep the old 5-year MOP. The longer MOP changes the EC value calculation significantly: no whole-unit rental, no second-property purchase, no resale to SC/SPR for 10 years.

2.6Above the HDB Income Ceiling

HDB resale has no income ceiling on the purchase itself. The S$14,000 family / S$21,000 extended-family / S$7,000 singles ceiling blocks only the HDB concessionary loan and the CPF Housing Grants (EHG, CHG). High-income buyers still need an HFE letter (mandatory regardless of loan route) and finance via bank loan at 75% LTV with TDSR 55% and MSR 30% at the MAS 4% stress floor. The Proximity Housing Grant (up to S$30,000) has no income ceiling and remains available.

2.7Million-Dollar HDB Flats — Worth It?

Q1 2026 set a record with 412 HDB resale flats sold at S$1 million or more — up 23.4% year-on-year. Average price S$1.151M. Hotspots: Toa Payoh, Ang Mo Kio, Bukit Merah, Queenstown. Million-dollar HDB sits in direct competition with S$1.4M Executive Condominium and S$2M private condo on a like-for-like budget. HDB wins on upfront cash (S$50K minimum vs S$100K for condo) and SSD-free exit; condo wins on flexibility and freehold options.

Part 3 — Singapore PRs & Foreigners

Singapore Permanent Residents face restricted property routes and a 5% ABSD on first property. Foreigners pay 60% ABSD on residential (with FTA exceptions for US, Switzerland, Norway, Liechtenstein and Iceland nationals).

3.1Singapore PR HDB Schemes and ABSD

SPRs can only buy HDB resale — never BTO. Four scheme routes: SC/SPR Family Scheme (one SC + one SPR, eligible from day one of PR status), Public Scheme (two SPRs, both must have held PR for 3+ years), Fiancé/Fiancée Scheme, and Single SPR (limited). ABSD 5% on first residential property, but the SC/SPR Married-Couple Remission can drop effective ABSD to 0% when declared at IRAS e-Stamping upfront with marriage certificate and statutory declaration. SPRs cannot take the HDB concessionary loan — bank loan only, 75% LTV.

3.2Hudson Place Case Study (one-north)

Hudson Place Residences, a 327-unit private condo at one-north, drew 3,500+ visitors over May Day 2026 weekend. Indicative pricing: 2BR Premium from S$1.4xxM, 3BR from S$2.0xxM, 4BR Premium from S$2.7xxM, 4BR+Flexi from S$3.4xxM at S$2,2xx-S$2,4xx psf. A worked case study on the BUC purchase route, with the 75% LTV math, stress-test instalments per unit tier, and the IPA timing required to compete in launch-weekend VIP allocation.

Singapore property ownership cycle: buy, own, refinance, decouple, sell — each stage has different rules.

Part 4 — Second Property & Decoupling

The 20% ABSD on a Singapore Citizen's second residential property (30% for PRs) makes the next purchase materially more expensive than the first. Decoupling is the legal route many couples use to wipe most of that cost away. The structural choice between joint tenancy and tenancy-in-common decides whether decoupling is even possible.

4.1Joint Tenancy vs Tenancy-in-Common — and the 99-1 Trap

Joint tenancy: equal undivided shares + right of survivorship (default for matrimonial purchases). Tenancy-in-common (TIC): defined shares which can be unequal (50/50, 80/20, 99/1) + no survivorship. The 99/1 ratio is legal when used to restructure existing joint ownership (decoupling). The 99-1 abuse pattern IRAS audits is the fresh-purchase two-stage transaction — sole buyer signs OTP at first-timer rates, then transfers 1% to a related party who already owns property, bypassing ABSD. IRAS clawback: original ABSD + 50% surcharge = 1.5x the avoided ABSD, with no statutory time limit.

4.2Decoupling Mechanics

Decoupling restructures an existing jointly-owned property so one spouse buys out the other. The bought-out spouse becomes a first-time buyer for ABSD purposes on the next purchase. On a S$1.5M private condo, total decoupling cost is typically S$30,000-S$80,000 (BSD on transferred share, SSD if within holding period, legal fees, mortgage refinancing). Against S$300,000 ABSD savings on a S$1.5M second property, the arithmetic almost always favours decoupling — provided the retaining spouse qualifies for the full mortgage on their income alone.

4.3Q1 2026 HDB Resale Market Read

HDB Resale Price Index dipped 0.1% in Q1 2026 — the first quarterly decline since 2019. Year-on-year still up 1.2%. The bifurcation is the bigger story: ordinary flats normalising, premium flats setting records. With fixed home loan rates from 1.40% and 1M SORA pegged-floating around 1.14%, the rate environment supports buyer activity even as headline supply softens.

Part 5 — Existing Owners

If you already own, the highest-EV moves are usually rate-side: refinance when the lock-in expires, monitor the SORA cycle, and time the package switch to the rate environment. Banks compete fiercely on lock-in-expiry refinance volume — the spread between staying on the post-lock-in board rate and refinancing is often 200+ basis points.

5.1Singapore Bank Rates Today

As of May 2026 across 16+ MAS-regulated banks: fixed packages from 1.40% p.a. (2-3 year lock-ins on qualifying loan sizes); 1M-SORA-pegged floating at 1M SORA + 0% spread, all-in ~1.14% effective and trending up; FHR-pegged hybrid packages in the 1.35-1.55% range on Year 1. Live rate tracking on the Nexus rates page is updated weekly from the MAS published SORA reference.

5.2When to Refinance

The two refinance triggers most owners ask about: "has my lock-in expired?" (30-second check on your loan letter) and "what would I save?" (5-minute run on the refinance calculator). Most Singapore banks require 3 months' notice. Start the refinance scan 4-6 months before lock-in expiry. The refinance timeline runs ~3 months end-to-end: 3M notice → multi-bank scan → IPA → Letter of Offer signing → legal completion → drawdown.

Owners of private property can also tap appreciated equity as cash via a cash-out refinance (equity term loan) — the Maximum Withdrawable Loan is 75% of valuation less outstanding loan less CPF used, available on private property and ECs past MOP (not HDB).

5.3IPA + Independent Broker

An In-Principle Approval (IPA) protects your 1% Option Fee. On new launches and competitive resale, multi-bank IPA via an independent broker returns approval in 14 days by running the file across multiple MAS-regulated banks in parallel. Banks have different appetites for variable income, foreign income, recent job changes, and self-employed profiles — single-bank applications mask this.

Part 6 — Sell & Exit Planning

Two often-misunderstood costs that bite at sale: Seller's Stamp Duty if you exit within the holding window, and CPF accrued interest refund that transforms expected cash proceeds into restricted OA balance. Plan both before listing.

6.1SSD 2025 Reset — the 4-Year Ladder

On 4 July 2025 MAS extended the Seller's Stamp Duty holding period from 3 years to 4 years and raised every tier by 4 percentage points. Current schedule for residential property purchased on or after 4 July 2025: 16% Year 1, 12% Year 2, 8% Year 3, 4% Year 4, 0% after. Applied to higher of sale price or open-market value. HDB flats remain SSD-exempt (5-year MOP covers them). Pre-reset purchases (11 March 2017 to 3 July 2025) stay on the old 3-year 12/8/4% ladder.

6.2CPF Accrued Interest on Sale

Every dollar of CPF Ordinary Account used to finance any residential property — HDB or private — accrues at 2.5% p.a. monthly compounded from withdrawal to the date of sale. On sale, sale proceeds first refund the CPF principal plus accrued interest to your OA before any cash reaches you. The refund mechanic does not destroy wealth; it relocates it from cash to OA (illiquid, post-55 withdrawal restrictions apply). Counter-intuitive twist: paying off a 1.40% bank loan with OA destroys ~1.10% per year of net wealth because OA earns 2.5%.
