Buying property in Singapore involves a uniquely Singaporean combination of CPF savings, HDB grants, concessionary loans, and MAS-regulated bank financing. For first-timers — especially those coming from overseas — this system can be bewildering. Here's how it all connects.
The Foundation: CPF (Central Provident Fund)
CPF is Singapore's mandatory social security savings system. All Singapore Citizens and PRs contribute a percentage of their salary into CPF each month:
- Below age 55: Employee contributes 20% of gross salary, employer contributes 17%
- The amount decreases progressively with age
CPF has three accounts:
- Ordinary Account (OA): Can be used for housing, education, and investment. This is the CPF account used for property purchases.
- Special Account (SA): Retirement savings, higher interest rate
- MediSave Account (MA): Healthcare expenses
For property: You can use CPF OA savings for:
- Down payment on an HDB flat or private property
- Monthly mortgage repayments (both HDB loan and bank loan)
- Stamp duty
Foreign nationals (EP holders who are not PR) do not contribute to CPF and cannot use CPF for property. Only citizens and PRs have this benefit.

HDB Flats: HDB Loan vs. Bank Loan
If you're buying an HDB resale flat or a BTO (Build-To-Order) flat, you have two loan options:
HDB Concessionary Loan
- Who qualifies: Singapore Citizens only (at least 1 buyer must be SC)
- Interest rate: Pegged at 2.6% p.a. (0.1% above the CPF OA rate) — not contractually fixed, but effectively stable (it has changed only once in nearly 20 years)
- LTV (Loan-to-Value): Up to 75% of the lower of purchase price or valuation (cut from 80% on 20 Aug 2024)
- Down payment: Minimum 25% (can be fully paid with CPF OA)
- No cash down payment required (you can use 100% CPF for the 25% down)
- No lock-in period: Can refinance to a bank loan later without penalty
Best for: First-timer SC buyers who want stability and don't need cash flow flexibility.
Bank Loan (for HDB)
- Who qualifies: All buyers (SC, PR, foreigners renting out/buying eligible property types)
- Interest rate: Market-determined, currently 3.0–4.5% p.a. (fixed or floating)
- LTV: Up to 75% (first property); lower for subsequent properties
- Down payment: 25% — at least 5% must be in cash (rest can be CPF)
- Lock-in periods: Typically 2–3 years; early repayment penalty of 1–1.5% applies
Note: Banks must comply with MSR rules for HDB loans (see below).

The Two Key Ratios: TDSR and MSR
The Monetary Authority of Singapore (MAS) enforces two debt ratios that determine how much you can borrow:
Total Debt Servicing Ratio (TDSR)
Applies to: All property types (HDB, EC, private, landed)
TDSR limits total monthly debt obligations to 55% of gross monthly income.
"Debt obligations" includes: the new mortgage + car loan + personal loans + student loans + credit card minimums.
Example:
- Gross monthly income: $8,000
- TDSR limit: $4,400/month
- Existing car loan: $1,200/month
- Maximum new mortgage: $3,200/month
At current rates (~4%), a $3,200/month repayment capacity supports a loan of approximately $650,000.
Mortgage Servicing Ratio (MSR)
Applies to: HDB flats and Executive Condominiums (EC) only — NOT private condos or landed
MSR limits the mortgage repayment to 30% of gross monthly income.
Example:
- Gross monthly income: $8,000
- MSR limit: $2,400/month for the HDB mortgage specifically
The MSR limit is always more restrictive than TDSR for HDB buyers. For a $8,000 income buyer, the MSR caps the HDB loan at ~$480,000–$500,000.
Private property buyers only face TDSR, not MSR.

Loan-to-Value (LTV) by Property Count
| Property Count | HDB Loan | Bank Loan |
|---|---|---|
| 1st property | 75% | 75% |
| 2nd property | Not available | 45% |
| 3rd+ property | Not available | 35% |
Outstanding loans: If you have an outstanding mortgage (e.g., on another property), LTV limits are further reduced.

Additional Buyer's Stamp Duty (ABSD)
ABSD is a significant cost for buyers of second properties or for foreign nationals.
| Buyer Profile | 1st Property | 2nd Property | 3rd+ Property |
|---|---|---|---|
| Singapore Citizen | 0% | 20% | 30% |
| Singapore PR | 5% | 30% | 35% |
| Foreigner | 60% | 60% | 60% |
Note: ABSD is on top of the standard Buyer's Stamp Duty (BSD), which is:
- 1% on first $180,000
- 2% on next $180,000
- 3% on next $640,000
- 4% on remainder up to $1M
- 5–6% for amounts above $1M (revised 2023)
For a foreigner buying a $2M condo, ABSD alone is $1,200,000 — this is why most foreigners rent rather than buy in Singapore.

HDB Grants for First-Timers (Singapore Citizens)
First-time HDB buyers (both SC) may qualify for:
| Grant | Amount | Eligibility |
|---|---|---|
| Enhanced CPF Housing Grant (EHG) | Up to $80,000 (BTO), $160,000 (resale) | Income ceiling applies ($9,000/month avg for BTO) |
| Proximity Housing Grant (PHG) | $10,000–$30,000 | Buying near or with parents |
| Family Grant | $50,000–$80,000 (resale) | First-timer families |
Grants are credited to CPF OA and used to offset the purchase price.

The Mortgage Process
- Get an In-Principle Approval (IPA) from a bank or HDB — confirms how much you can borrow
- Exercise Option to Purchase (OTP) — requires payment of 1% option fee
- Finalise loan — submit full loan application with income documents
- Sign Sale and Purchase Agreement
- CPF board approves CPF usage for the property
- Completion — balance payment, key collection
Timeline: BTO flats take 3–5 years to build. Resale HDB transactions complete in 8–12 weeks. Private property completion varies (typically 10–12 weeks for resale).

Working with a Mortgage Broker
A mortgage broker compares packages across multiple banks simultaneously and helps you navigate TDSR/MSR calculations. In Singapore, mortgage brokers are free to the buyer — they earn a referral fee from the bank. Look for MAS-regulated financial advisers or use platforms like MoneySmart, DollarBack, or SGLinkUp's mortgage service request feature to get connected.
