Short answer：A second mortgage adds borrowing against a property that is already mortgaged; it is not simply a transfer of the existing loan. Before considering a developer’s offer, check first-lender consent, both sets of terms, payments after any introductory period and money due at maturity.
Second mortgage versus refinancing
IFEC distinguishes additional borrowing from another institution against the same mortgaged property from transferring the existing mortgage to another lender. A developer’s sales offer is not itself confirmation of bank approval.
Check consent and mortgage documents
A 2015 government reply describes first-mortgage consent clauses and the first lender’s repayment priority on disposal. We use it only for that background, not current rates, lending limits or statutory interest caps. Have the lender and solicitor check your actual documents.
Questions before signing
| Check | Obtain | Do not assume |
|---|---|---|
| First-lender consent | Written consent and restrictions | Developer acceptance is bank consent |
| Complete costs | Loan amount, interest basis, fees and conditions | A small deposit means a cheap loan |
| Changing repayments | Later payments and amount due at maturity | Refinancing will certainly be available |
| Early exit | Settlement and rebate recovery terms | Another borrower’s terms apply to you |
These are editorial questions, not an approval model. Verify an intermediary’s identity, service scope and charges before signing; an easy-approval claim is not a substitute for understanding the documents.
A hypothetical combined-payment budget
| Monthly item | Initially | Illustrative later scenario |
|---|---|---|
| First loan | HK$18,000 | HK$18,000 |
| Second loan | HK$6,000 | HK$9,000 |
| Total | HK$24,000 | HK$27,000 |
The example requires another HK$3,000 a month. It demonstrates addition, not a product amortisation schedule. Record any lump sum due at maturity separately, without treating an assumed future refinance as confirmed funding.

Questions and answers
Is a second mortgage the same as refinancing?
No. It adds borrowing against an already-mortgaged property; refinancing transfers the existing mortgage to another lender.
Is a developer second mortgage guaranteed approval?
No. Check consent, loan conditions and your repayment budget separately; do not rely on advertising alone.
Can I always refinance after an introductory period?
Do not assume that. Valuation, income and lending conditions may change. Plan how to repay if refinancing is unavailable.

First versus second mortgages: compare the whole repayment schedule
| Check | First mortgage | Second mortgage |
|---|---|---|
| Security and consent | Existing mortgage terms | Second-ranking security and required consent |
| Annual rate | Benchmark, margin and reset date | Promotional rate, later rate and effective date |
| Monthly burden | First-mortgage payment | Both payments plus any lump sum at maturity |
| Exit costs | Early repayment and cashback recovery | Second-loan fees and refinancing restrictions |
A promotional rate does not cover the entire loan term. Obtain schedules for the promotional period, later period and a higher-rate scenario. Check interest-only periods and principal due dates. This article does not rank current second-mortgage offers; quotations need dates and eligibility conditions.
