TDSR and LTV Requirements

Understanding TDSR (Total Debt Servicing Ratio) and LTV (Loan-to-Value) is crucial for loan approval and optimal financing.

TDSR Calculation

≤ 55%
Maximum TDSR Allowed
Formula:
TDSR = (Total Monthly Debt Obligations ÷ Gross Monthly Income) × 100%

Includes:

  • • Proposed mortgage payment
  • • Existing loans (car, personal, etc.)
  • • Credit card minimum payments
  • • Other property loans

LTV Requirements

Refinancing Strategies

When to Refinance

Refinancing can save thousands in interest, but timing and execution are crucial for maximizing benefits.

Rate Differential

Consider refinancing when new rates are at least 0.5% lower than your current rate.

Break-even Analysis

Calculate when savings exceed refinancing costs, typically 2-3 years for optimal timing.

Lock-in Considerations

Factor in penalty fees if refinancing within lock-in periods, usually 1-5 years.

Refinancing Checklist

Before Refinancing

  • Review current loan terms and rates
  • Calculate remaining principal and tenure
  • Check credit score and income stability
  • Research market rates and packages

During Process

  • Compare total cost, not just interest rates
  • Negotiate package deals and waivers
  • Time application to avoid rate increases
  • Ensure seamless transition between loans

Expert Tips & Strategies

Rate Lock Strategy

Consider shorter lock-in periods (1-2 years) in rising rate environments, longer periods (3-5 years) when rates are expected to increase.

Pro Tip: Monitor SORA trends and Fed policy for timing decisions.

Package Optimization

Bundle home loans with salary crediting, insurance, and investment products for better rates and fee waivers.

Pro Tip: Calculate total relationship value, not just loan savings.

Prepayment Strategy

Use bonuses and windfalls for loan prepayments, especially in high-rate periods. Consider opportunity cost vs guaranteed savings.

Pro Tip: Prepay when loan rate exceeds investment returns.

Negotiation Tactics

Use competing offers as leverage. Banks often match or beat competitor rates for customers with strong profiles.

Pro Tip: Time negotiations during bank promotion periods.
