Home loans, SORA and refinancing in Singapore

A Singapore home loan is limited by the Total Debt Servicing Ratio (TDSR), the Mortgage Servicing Ratio (MSR) for HDB flats and new executive condos, and loan to value limits, and its cost depends on whether the rate is fixed or tied to SORA. The guides below explain how much you can borrow, how to compare bank packages, when refinancing makes sense and what happens when a valuation comes in low. Start with the borrowing limit guides, then compare current packages on the mortgage rates tool.

Quick answers

  • What Is TDSR and How Much Can I Borrow?: TDSR caps all monthly debt repayments at 55% of gross income, stress tested at 4% p.a. Most buyers qualify for 10 to 20% less than online calculators suggest.
  • How Much Can I Borrow for an HDB Flat?: MSR caps the HDB loan instalment at 30% of gross income, TDSR caps all debt at 55%. An HDB loan is also capped at 75% LTV, the same as a bank loan.
  • HDB Loan or Bank Loan, Which Is Better?: The HDB loan is 2.6% p.a. with no cash downpayment and no lock in. A bank loan is cheaper, around 1.5%, but needs 5% cash and carries a lock in penalty.
  • How Does Refinancing a Mortgage Work?: Refinancing means taking a new home loan, usually from a different bank, to replace your existing one, paying legal and valuation costs to switch onto a more competitive rate once your lock in period ends.
  • What Happens to My Mortgage if Rates Rise?: Fixed rate packages don't change until they expire. Floating SORA linked rates move immediately. Banks already stress test approvals at 4% p.a., regardless of the actual rate.
  • What Is a Lock In Period on a Home Loan?: A lock in period is the initial window, commonly 2 to 3 years, during which refinancing, repricing, or a partial or full early redemption of your home loan triggers a penalty, usually a percentage of the amount repaid.
  • What Is a Bridging Loan?: A bridging loan covers the cash gap when your new home completes before your existing one sells. Rates run 3.5 to 5% p.a. for 6 to 12 month tenures.
  • How Does a Bank Valuation Differ From Asking?: The asking price is what a seller wants and a buyer agrees to pay. The bank valuation is an independent panel valuer's estimate, and it decides your loan quantum.
