HOS Mortgage Referral Hong Kong: How Referral Platforms Work for Subsidised Flat Buyers

If you've secured an HOS flat through the ballot or are buying through the HOS secondary market, a mortgage referral service (按揭轉介) can help you compare participating lenders. It is an intermediary, not the bank or the Housing Authority. Some providers advertise a cash rebate when a referred loan is drawn down, but the amount and conditions vary. HOS financing may fall under a Housing Authority guarantee and, where applicable, HKMCI Mortgage Insurance Programme arrangements that can support high loan-to-value (LTV) lending for eligible buyers, so the right comparison depends on whether you are buying a new HOS flat or through WSM, your Green Form or White Form status, the flat's valuation, and the lender's approval. The useful question is not simply whether a platform offers cashback, but what it will submit, which lenders it can approach, and what you will actually pay over the life of the loan. Rates, rebates, eligibility and guarantee terms can change, so verify the current scheme guidance and the bank's written offer before signing.

What a Mortgage Referral Platform Actually Does

Mortgage referral platforms in Hong Kong — including mReferral (經絡按揭轉介), 28 Mortgage, and other brokers — act as intermediaries between you and participating banks. They are not lenders and cannot approve or deny your mortgage. Depending on the provider and your consent, they may:

1. Collect your borrower profile (income, property details, loan amount, and HOS or private-market status) and refer your details to selected partner banks.
2. Show or explain available offers — which may include a HIBOR-linked or Prime-linked rate, a promotional period, a bank rebate, or other conditions.
3. Offer an additional incentive if the provider's arrangement includes one. A bank may pay a referral commission after drawdown, and a provider may pass some of that value to the customer, but this is not automatic.

Do not assume that a referral application has the same rate or terms as a direct application. Ask how the platform is paid, whether your information will be registered with particular banks, whether the submission is a formal mortgage application, and whether any rebate depends on drawdown, minimum loan size, or a lock-in period. Get the offer and the rebate conditions in writing before relying on them.

The rebate is a promotion, not a guaranteed reduction in your borrowing cost. Compare the effective rate, cap, fees, lock-in terms, and total interest as well as any cash payment.

How HOS Mortgages Differ from Private Market Mortgages (and Why It Matters for Referral)

When you use a referral platform for an HOS flat, the loan structure differs from a private market property in several ways that affect which mortgage terms are available and how you compare them:

LTV and the Housing Authority Guarantee

HOS and other subsidised-sale-flat buyers may have access to HA mortgage-default guarantees or the HKMCI Mortgage Insurance Programme, but the exact arrangement depends on the scheme, the flat, and the lender. For example, the current WSM guidance says that, during the first 40 years, the HA guarantee for an eligible White Form buyer can cover a loan up to 90% of the lower of the assessed value or purchase price. HKMCI also describes MIP lending of up to 95% for eligible Green Form WSM buyers, subject to its requirements.

• Green Form (GF): The applicable ceiling can be higher than standard bank lending, but confirm the current HOS or WSM terms.
• White Form (WF): WSM guidance states up to 90% of the lower of assessed value or purchase price for the relevant guaranteed period.

In the private market, borrowing above the standard bank LTV generally requires the Mortgage Insurance Programme (MIP). An HOS buyer should not assume that the HA guarantee always removes MIP: the Housing Authority says a WSM buyer who needs more than 80% LTV may need to apply for MIP, which has its own eligibility rules and premium options. The guarantee also does not guarantee approval or a particular bank rate.

Interest Rate Competition on HOS Loans

Banks may still compete on HOS mortgage packages, but offers can differ by scheme, property, borrower profile, and promotion. Compare:

• The rate structure — for example, a HIBOR-linked rate with a Prime-rate cap or a Prime-linked rate.
• Cash rebates and fees — a larger rebate may not compensate for a higher rate or more restrictive terms.
• Promotional or fixed-rate periods — check what rate applies after the initial period and whether early repayment triggers a charge.

The practical takeaway: use the referral comparison to evaluate the complete package, not just the headline cashback. A platform may not have access to every lender or every direct-bank promotion.

Maximum Mortgage Term

The maximum term is not a universal promise made by a referral platform. The HA's current information states that qualifying new HOS loans can have repayment periods of up to 30 years, and WSM guidance says the maximum repayment period for HOS, GSH, and TPS flats in the secondary market is also up to 30 years after the March 2024 changes. The lender will still assess the flat, valuation, borrower, and remaining term under the relevant guarantee.

The Referral Process Step by Step

Here's what the process typically looks like for an HOS buyer using a referral platform:

1. Confirm the purchase route. A new HOS ballot purchase and an HOS flat bought through WSM or another secondary-market route do not have identical mortgage arrangements.

2. Submit your details to the referral platform. You'll usually provide the property's assessed market value and purchase price, income documentation, the loan amount you're seeking, and whether you're Green Form or White Form. Before submitting, check the consent wording and which banks or lenders may receive your information.

3. The platform refers your profile to selected partner banks. Each bank assesses the case against its own credit criteria and may return an offer. A platform's comparison is not a mortgage approval.

4. You receive a comparison of offers showing each bank's rate structure, cap, rebate, fees, and special conditions. Timing varies, and some platforms only show offers from lenders to which they have referred your case.

5. You select a bank and proceed with that bank's formal mortgage application. A referral submission is not necessarily a formal application; the approval process is between you and the bank, subject to the bank's and any insurer's rules.

6. After drawdown, any promised platform rebate is paid only if the written offer conditions are met. The timing and any clawback are provider- and bank-specific.

What to Watch For: Clawback Periods and Conditions

Cash rebates are usually conditional, but there is no single industry-wide clawback period. A bank or platform may require repayment if you refinance, repay early, or breach the offer terms. Read the bank's and platform's documents separately; do not assume that their eligibility rules or clawback periods match.

Other conditions to check:

• Minimum loan size. Some rebate offers only apply above a stated loan amount.
• Referral registration. A bank may recognize one intermediary for a case. Signing a referral letter or authorizing a submission can affect which provider receives any commission or rebate, so read before you sign and do not submit the same case through several platforms without checking.
• Eligible banks. Not every bank participates in every platform. If you have a preference for a specific bank, confirm it is in the platform's network before submitting.
• Timing. Referral offers can change. Confirm that the written rebate terms still apply when you submit and when the loan is drawn down.

Should You Use a Referral Platform or Go Directly to a Bank?

Using a referral platform can be convenient and may unlock a provider-specific rebate, but it does not guarantee a lower total cost or the same terms as a direct application. Compare like-for-like written offers from the same bank where possible, and ask whether the platform is free, non-binding, and paid by the bank or another party.

Common reasons for going bank-direct include:

1. You have a strong existing relationship with a specific bank (e.g., substantial deposits, payroll account, or private banking status) and that bank's relationship manager is offering a preferential rate or rebate. Compare the complete written offer with any referral offer rather than assuming one route is better.

2. You want to apply to a single bank and nowhere else. Some buyers prefer the simplicity or want to avoid referral-registration issues. Ask the platform whether its submission is free and non-binding before authorizing it.

For many HOS buyers — especially first-time purchasers comparing several lenders — a referral route can save time and make rebates easier to compare. It is not automatically better: the right choice depends on the written rates, fees, conditions, lender coverage, and your preference for dealing directly with a bank.

How This Fits Into the Broader HOS Purchase Timeline

For a new HOS purchase, mortgage arrangement is one piece of a larger buying process that includes the ballot application, flat selection, signing the Agreement for Sale and Purchase (ASP), and legal conveyancing. WSM and other secondary-market purchases follow their own scheme and sale documents. The Hong Kong First-Time Home Buyer Guide covers the broader process for both HOS and private market purchases, including the alienation premium calculation, stamp duty obligations, and the financial modelling you need to do before committing to either track.

If you're still weighing whether to enter the HOS ballot or buy in the private market, that decision should come before mortgage shopping — the financing structures are fundamentally different, and the comparison isn't as simple as looking at interest rates alone.

Key Takeaways

• Mortgage referral platforms in Hong Kong are intermediaries, not lenders. They may compare or refer you to participating banks, but the scope and any rebate depend on the platform's written terms.
• HOS and WSM mortgage arrangements can support high LTV lending for eligible buyers. WSM buyers who need more than 80% LTV may still need MIP, so confirm the exact scheme, valuation, guarantee, and premium requirements.
• Bank and platform rebates can have different eligibility, timing, and clawback terms. Read both sets of conditions before treating a rebate as part of your budget.
• A referral route can be useful for comparing HOS mortgage offers, but compare the full cost and do not assume it will produce the same rate as a direct application.
