Results
At a glance:The down payment is the portion of the price the buyer must pay themselves and cannot finance with a mortgage; the down-payment ratio plus the loan-to-value ratio (LTV) always sum to 100%. Down payment = price × down-payment ratio%; mortgage loan = price − down payment. In Hong Kong the LTV is regulated by the HKMA countercyclical measures: from 28 February 2024, a self-used residential property at HK$30M or below is capped at 70% LTV (30% deposit), and the higher the price the lower the LTV; a higher-ratio mortgage requires the Mortgage Insurance Programme (MIP) and a premium.
Formula
Down payment = price × (down-payment ratio% ÷ 100).
Mortgage loan = price − down payment.
Down-payment ratio + LTV = 100%.
$$\text{DownPayment} = \text{Price} \times \dfrac{\text{DownPercent}}{100}$$$$\text{LoanAmount} = \text{Price} - \text{DownPayment} = \text{Price} \times (1 - \text{LTV})$$How to Use
- Enter the property transaction price.
- Set the down-payment ratio (e.g. 30% for self-used).
- Instantly get the deposit cash needed and the mortgage loan to borrow.
FAQ
What is the minimum down payment for buying property in Hong Kong?
Under the HKMA countercyclical measures effective 28 February 2024, a self-used residential property at HK$30M or below is capped at 70% LTV (30% deposit); above HK$35M the cap is 60% (40% deposit), with a graduated reduction between HK$30M and HK$35M. To buy with a lower deposit (as low as 10%), you must use the Mortgage Insurance Programme (MIP) and pay a premium. Actual ratios follow the bank and the HKMC Insurance at the time.
What is the difference between the down-payment ratio and the LTV?
They are two sides of the same thing: the down-payment ratio is the share you pay in cash, the loan-to-value (LTV) is the share the bank lends, and they always sum to 100%. For example, a 30% deposit means a 70% mortgage. You can use our mortgage calculator to estimate the corresponding monthly payment.
What is the maximum LTV under Mortgage Insurance (MIP)?
Under the current HKMC Insurance Mortgage Insurance Programme, for a property at HK$10M or below where all applicants are salaried, fixed and do not own a Hong Kong residential property, the maximum is 90% LTV (10% deposit); other cases are generally capped at 80%, with a property-price ceiling of about HK$17.15M. MIP requires a premium and approval; details follow the HKMC Insurance.
Is the stress test still required for a mortgage now?
From 28 February 2024 the HKMA 'paused' the stress-test requirement assuming a 2-percentage-point (200 bps) rate rise. Banks now mainly assess the debt-to-income (DTI) ratio: the general cap for self-used residential is 50%, or 40% if you have other mortgage burdens or guarantees. Arrangements follow the latest HKMA guidance.
Besides the down payment, what other costs should I budget for?
Beyond the deposit there is ad valorem stamp duty (tiered by price), legal fees, estate-agency commission, mortgage insurance premium (for high-ratio mortgages) and renovation/miscellaneous costs. These are all paid in cash, so the actual cash needed exceeds the down-payment amount. Budget for them up front — our stamp-duty tools can help estimate the tax.
