Cost Breakdown of a Typical Mortgage Loan in Singapore

Introduction

Buying a home in Singapore is a significant financial milestone, but also one of the largest expenses you’ll ever incur. While most homebuyers are aware of the property price and basic loan repayment commitments, many overlook the detailed cost breakdown of a typical mortgage loan.

Understanding the full range of costs associated with taking up a home loan—from downpayments to interest rates, legal fees to insurance requirements—can help you plan your finances better, avoid nasty surprises, and even save money in the long run.

This comprehensive guide will provide an in-depth breakdown of what you’re actually paying for when you take a mortgage loan in Singapore, whether you’re buying a BTO flat, resale HDB, executive condominium (EC), or private property.

1. Property Purchase Price vs. Valuation

The cost of your mortgage loan starts with the lower of the purchase price or the property’s valuation. This is the base amount that your Loan-to-Value (LTV) limit will be applied to.

• If you’re buying a property for $1,000,000, and the bank’s valuation is $950,000, your mortgage loan will be based on $950,000.

• Any amount above valuation (known as Cash Over Valuation, or COV) must be paid in cash, and is not covered by CPF or the mortgage.

---

2. Downpayment

HDB Loan (Direct from HDB):

• Minimum 10% downpayment, payable entirely using CPF Ordinary Account (OA) funds.

• No cash component is required if you have sufficient CPF balance.

Bank Loan:

• Minimum 25% downpayment.

  • 5% must be paid in cash

  • 20% can be paid with CPF OA or cash

For a $600,000 property with a bank loan:

• Cash downpayment = $30,000 (5%)

• CPF or cash downpayment = $120,000 (20%)

This downpayment must be ready before loan disbursement and is typically paid in tranches—option fee, exercise fee, and completion.

---

3. Loan Amount (Principal)

This is the amount borrowed from the bank or HDB to finance your property purchase after accounting for downpayment.

Based on a property worth $1,000,000 and a 75% LTV limit:

• Loan amount = $750,000

This principal amount is repaid over time, with interest, through monthly instalments.

---

4. Interest Payments

Interest is the cost of borrowing money from a financial institution.

HDB Loan:

• Fixed at 2.6% per annum, pegged at 0.1% above the CPF OA interest rate (currently 2.5%).

Bank Loans:

• Vary based on market conditions.

• Fixed-rate packages (typically fixed for 1 to 5 years): 3.30% to 3.85% (2025 range).

• Floating-rate packages pegged to SORA: ~3.10% to 3.50%

Example:
Loan amount: $750,000
Interest rate: 3.2%
Loan tenure: 25 years
Estimated monthly instalment: ~$3,630
Total interest over 25 years: ~$339,000

This means you are paying $1.09 million in total over the life of the loan, with $339,000 going toward interest alone.

---

5. Legal Fees

Legal fees are required to:

• Draft loan documents

• Facilitate the transfer of title

• Execute mortgage contracts

• Register the mortgage with the Singapore Land Authority

Typical range: $2,000 to $3,000
If you refinance, legal fees apply again, although some banks offer subsidies as part of promotional refinancing packages.

Banks usually work with panel law firms, and you’ll be required to select from these firms when applying for a mortgage.

---

6. Valuation Fees

Before approving a mortgage, banks will need to determine the market value of the property.

Typical range: $200 to $500
Valuation fees are generally higher for private properties than for HDB flats.

This value directly affects the LTV ratio and may impact how much of the purchase price you can finance through the mortgage.

---

7. Stamp Duty

Stamp duty is a mandatory tax payable to the Inland Revenue Authority of Singapore (IRAS) and must be paid within 14 days of signing the Sale & Purchase Agreement.

Buyer’s Stamp Duty (BSD) Rates (2025):

For a $1.2 million property, BSD would be:

• 1% on first $180,000 = $1,800

• 2% on next $180,000 = $3,600

• 3% on next $640,000 = $19,200

• 4% on remaining $200,000 = $8,000
  Total BSD = $32,600

Note:
Additional Buyer’s Stamp Duty (ABSD) applies if you are purchasing a second or subsequent property, or if you’re a foreigner.

---

8. Fire Insurance and Mortgage Insurance

Fire Insurance:

Mandatory for HDB loans and often required for bank loans.

Cost: ~$50 to $150 per year
Covers structural damage due to fire, but not household contents.

Mortgage Reducing Term Assurance (MRTA) / Home Protection Scheme (HPS):

• HPS is required for HDB buyers using CPF.

• MRTA is optional for private property loans but may be offered as part of loan protection.

Cost: Varies based on loan amount, age, and coverage. Could be $500 to $2,000 per year.

9. Loan Servicing Costs and Structures

Total Debt Servicing Ratio (TDSR):

• Ensures total debt repayments do not exceed 55% of borrower’s gross monthly income.

Mortgage Servicing Ratio (MSR):

• Applies to HDB and EC buyers.

• Caps home loan repayment to 30% of gross monthly income.

Amortization:

• In early years, a large portion of your monthly repayment goes to interest, not principal.

• Over time, more of your payment goes toward reducing the loan balance.

---

10. Repricing and Refinancing Fees

After your lock-in period ends (usually 2–3 years), your interest rate often increases (reversion rate). You may:

• Reprice (switch packages with the same bank)

  • Admin fee: ~$500

• Refinance (switch to another bank)

  • Legal and valuation fees: ~$2,500–$3,500

  • Subsidies may be offered to offset costs

---

11. Early Repayment Penalties

Most bank loans include a lock-in period. If you pay off the loan early or refinance during this period:

• Penalty: ~1.5% of outstanding loan amount

For a $500,000 outstanding loan, this equates to $7,500.

Some banks may waive the penalty under special circumstances, such as sale of property or death of borrower.

---

12. Monthly Mortgage Instalments

Your actual monthly repayment depends on:

• Loan amount

• Interest rate

• Loan tenure

Example:

Use mortgage calculators to estimate your actual instalments based on various scenarios.

---

13. CPF Usage Limitations

When using CPF OA for monthly repayments or downpayment, be aware of the Valuation Limit (VL) and Withdrawal Limit (WL).

• VL = Lower of purchase price or valuation

• WL = 120% of VL
  Beyond this, CPF usage is restricted unless you meet your Basic Retirement Sum (BRS).

---

14. Optional Costs to Consider

Renovation Loans:

• Some homeowners take up renovation loans on top of their home loan.

• Interest rate: 3% to 5%

• Tenure: Up to 5 years

• Max loan amount: ~$30,000

Furnishing and Appliances:

• Often excluded from the mortgage but necessary expenses.

• Budget at least $10,000 to $30,000 depending on property type and size.
