Four Variables That Drive Your Loan-to-Value
First, the property itself: price level, completed vs pre-sale, owner-occupied vs tenanted — all affect the share a bank is willing to lend.
Second, the buyer's status and income type: employed, self-employed, or holding through a company are assessed differently; a fixed monthly salary is usually easier to evaluate than variable income.
Third is the repayment tenor; fourth is the regulatory regime at the time. The former drives the monthly payment, the latter caps the loan-to-value and sets approval thresholds.
How Repayment Capacity Is Assessed
The bank looks at “the amount you can reliably devote to repayment each month”, usually expressed as a ratio of repayment to income. Existing debts — personal loans, credit-card instalments, mortgages on other properties — are counted alongside the new mortgage payment.
That explains why “clearing a small loan first” can sometimes visibly improve the approval outcome: it lowers your overall debt burden.
Proof of income, tax returns, MPF records and bank statements are standard documents; the self-employed need fuller income evidence and company documents.
HIBOR-linked vs Prime-linked: Different Sources of Volatility
Hong Kong commonly offers two rate mechanisms: one pegged to the Hong Kong Interbank Offered Rate (H plan) and one pegged to the banks' Prime Rate (P plan). The difference lies in which benchmark the rate follows and whether a cap applies.
H-plan rates move more in the short term, but most plans carry a cap based on the Prime Rate; P plans are steadier. Which to choose depends on your tolerance for rate swings and the rate environment at the time.
Also watch cash rebates and the penalty period (charges for early repayment or refinancing) — their real value can matter more than headline rate differences.
Documents to Have Ready Before Applying
Identity documents, proof of income, proof of address, and the Provisional Agreement for Sale and Purchase. If the purchase goes through a company or needs a guarantor, add the company documents and the guarantor's financials.
Scan everything and submit the complete set against a checklist in one go; missing documents are the single most common cause of approval delays.
After Approval, a Few More Steps
The bank arranges the property valuation and computes the final loan against it. If the valuation comes in below the price, cover the gap in cash.
Solicitors then handle the mortgage deed and the formal agreement; in some cases mortgage insurance or fire insurance is also required. These steps all anchor to the completion date, so leave slack in the schedule.
Where to Check the Latest Rules
LTV caps, the debt-servicing guidance and the stress-test methodology are adjusted by the regulator with market conditions. Any hard-coded number risks being stale — which is why this article deliberately quotes none.
The reliable approach: follow the latest guidance on the regulator's official website, and get pre-assessments directly from several banks to cross-check.
