- Monthly payment depends on loan amount, interest rate, and term
- Longer terms mean lower monthly payments but more total interest
- Even small rate differences significantly impact total cost
- Use calculators to compare different scenarios
How Mortgage Payments Work
Your monthly mortgage payment consists of two parts:
- Principal: The amount that reduces your loan balance
- Interest: The cost of borrowing money
In the early years, most of your payment goes toward interest. As the loan matures, more goes toward principal.
Key Variables
Loan Amount
The amount you borrow = Property Price - Down Payment. In Hong Kong, typical LTV ratios are 60-90% depending on property value and buyer status.
Interest Rate
Hong Kong mortgages are typically based on HIBOR (Hong Kong Interbank Offered Rate) or Prime Rate. Current rates (2025) range from approximately 4-5% p.a.
Loan Term
Most Hong Kong mortgages have terms of 25-30 years. Shorter terms mean higher monthly payments but less total interest.
