Why Older HOS Flats Fail Mortgage Approval
🎧 Listen to this article
But after signing the provisional agreement and going to the bank for loan approval, they are suddenly told "the loan amount is insufficient," "the mortgage term must be shortened," or even "proof of high income is required," causing a huge budget shortfall and possibly leading to forfeiture of the deposit. Why does the bank ultimately not approve the full amount?
Before we break down the real pain points, we first need to understand a concept that most people in Hong Kong misunderstand!
💡 One-minute realistic explanation: Why does an "older" flat make it harder to get a mortgage?
Many people think that the Housing Authority extending the guarantee period to 50 years means "the government guarantees it for 50 years, so buyers can borrow for 30 years and repay slowly." This is a huge misconception!
When dealing with older HOS flats, the bank's actual formula is: "First assignment date (flat age) + mortgage term ≈ cannot exceed 50 years (depending on the bank's internal limit)".
Why do older HOS flats cause buyers to lose their budget?
🧮 Realistic cruel simulation: Suppose you buy a second-hand HOS flat that is "35 years old"
- Fatal point 1: Mortgage term is drastically shortened Buyers think they can borrow for 30 years, but the bank calculates (50-year risk limit - 35 years flat age = 15 years) and may only approve a mortgage term of about 15 years.
- Fatal point 2: Monthly payments skyrocket, making the stress test extremely difficult When the repayment period suddenly shortens from 30 years to 15 years, the monthly payment amount increases significantly. Combined with interest rate factors, the bank's strict requirements for the Debt Service Ratio (DSR) and stress test make it very difficult for buyers to pass approval.
- Fatal point 3: Unstable income makes it hard to pass As the remaining risk window of the unit narrows, the bank considers: The older the flat, the harder it is to resell in the future, and the uncertainty of the collateral's (property) value increases. Although the bank can repossess and auction the property without losing everything, to avoid taking on too much risk, the bank tightens approval and strictly requires buyers to provide proof of income. For Green Form / WFSM grassroots buyers who rely on elderly allowances, odd jobs, or have no fixed income, they simply cannot provide impressive tax returns. This is the real reason they are ultimately denied mortgage approval by the bank!
After understanding this core logic, let's immediately break down the 3 most common real pain points for second-hand HOS mortgages:
1. Pain point 1: "Why did the neighbor get a full loan, but my flat didn't get approved for the full amount?"
This is the most common shocking experience for buyers. Same building, same layout, why are the mortgage results completely different?
- The "first assignment date" is the key: The bank's approval benchmark is never based on the entire estate's completion year, but strictly follows the Housing Authority's official mortgage guidelines, calculated from the "date of first assignment to the buyer" of the individual unit.
- Historical differences: If the unit you buy was a "leftover unit" of the estate or was first sold under a later HOS scheme, its remaining guarantee period will be longer than other units in the same estate. Conversely, if it was among the first units sold, the guarantee period will be shorter. Therefore, mortgage terms cannot be generalized with neighbors.
📝 Real case (Tin Chung Court, Tin Shui Wai as an example): The most classic case of "same estate, different fate" in the market is Tin Chung Court in Tin Shui Wai, where some blocks were delayed until 2013-2014 for sale as "leftover units" due to the short pile incident. The estate was completed as early as 1999, with most units having a first assignment date around 2000, resulting in a shorter remaining guarantee period and easily restricted mortgage terms and loan amounts. However, Blocks K and L of the same estate, due to the delayed sale, have a first assignment date of 2014, giving them a very long remaining guarantee period, allowing them to easily borrow the maximum loan amount and longest term. If buyers only look at the "estate age" without checking the land registry, they may face a drastically shortened mortgage term and need to raise additional down payment at the last minute.
2. Pain point 2: "They say the maximum guarantee is 50 years, but why does the bank still look at income?"
The policy relaxation has indeed brought convenience, but in practice, banks often have their own risk management bottom lines.
- Cautious approval during the transition period: Although the guarantee arrangement has been relaxed, when the remaining guarantee period of the unit is relatively short (e.g., the first assignment date is close to 40 years), some banks adopt a more cautious approval attitude. In practice, banks may not fully exempt the "stress test (depending on bank policy)" but may require applicants to provide stable income proof for assessment.
- Consequences of guarantee expiry: If the unit's guarantee period has fully expired (i.e., over 50 years), the mortgage for that unit will generally be approved under "private housing mortgage standards." This means the unique advantages of HOS, such as high loan-to-value ratio without insurance premiums, will disappear, and the loan-to-value ratio will be significantly reduced (buyers may need to apply for general mortgage insurance to borrow a higher ratio).
3. Pain point 3: "Why is the valuation conservative even with a guarantee?"
This is a rarely warned issue by agents, but buyers must be mentally prepared.
- Impact of major repairs and mandatory building inspection: Older HOS estates commonly face building maintenance cycles. If the estate has received a mandatory building inspection notice (or even a fire safety directive) from the Buildings Department, or if the Incorporated Owners is preparing for major renovations, in some cases, the valuation from surveyors may be more conservative.
- Bank stance: In such individual cases, the final approved mortgage amount may be less than what the buyer originally expected, and the buyer will need to make up the difference themselves.
💡 Practical strategies
To ensure a smooth purchase, prospective buyers must do the following homework before placing a deposit:
- Check the land registry yourself to find the first assignment date
- Seek a pre-assessment from the bank before signing the contract
- Reserve sufficient down payment
📌 FAQ
Q1: If a second-hand HOS flat has already paid the land premium (open market), is it still subject to the guarantee period restriction?
No. A HOS flat that has paid the land premium is treated as a general private residential property in the mortgage market. Buyers must follow the HKMA's conventional mortgage guidelines for private housing and are free to apply for mortgage insurance schemes, no longer bound by the Housing Authority's guarantee period mechanism.
Q2: I am an elderly applicant (e.g., Green Form). Will my age shorten the HOS mortgage term?
In subsidized housing mortgages without land premium paid, banks generally focus more on the "remaining guarantee period" and are less likely to shorten the term solely due to the applicant's age (as commonly seen in private housing with "75 minus age"). However, if the unit's remaining guarantee period is short, the bank may still consider the applicant's age and repayment ability comprehensively. The actual result depends on the final approval of the individual bank.
