Can an HOS owner let on the open market? Check the restriction period and premium
Whether a Home Ownership Scheme owner may let on the open market depends on the sale exercise, first assignment date and deed terms. Once the applicable restriction permits it, the owner must pay the assessed premium in full before letting. The premium reflects the original discount applied to today's unrestricted value.
Identify the restriction that applies to this flat
Start with the date when the Housing Authority (HA) first assigned the flat to an owner, the HOS exercise in which it was first offered for sale, and the actual deed of assignment and Government lease. The year in which you bought a resale flat or the age of its building is not enough. HA's published examples below show why there is no single waiting period for all HOS homes. Even after the relevant period, payment of premium must come before an ordinary open market letting.
A sale in the HOS Secondary Market to an eligible buyer may take place without paying premium under the rules for that flat. That is a different route from an open market tenancy: permission to sell to an eligible buyer does not permit general letting without premium. HA also operates a specified letting scheme for eligible owners and tenants of premium unpaid subsidised sale flats. Its permits and eligibility rules are separate from ordinary open market letting.
| Exercise first offered | HA's open market sale or letting point | What to check |
|---|---|---|
| HOS 2018 | After 5 years from first assignment, with premium paid first | Confirm this flat's deed terms |
| HOS 2022 and 2023 | After 15 years from first assignment, with premium paid first | Earlier resale follows the relevant Secondary Market rules |
| HOS 2025 | After 10 years from first assignment, with premium paid first | This is the 2025 sale arrangement; other exercises differ |
Estimate the premium from the original discount
HA's principle is to apply the original percentage discount, measured against the flat's initial market value, to its prevailing unrestricted market value at assessment. For flats first offered under HOS 2018 to 2023, the discount figures come from the first assignment; for HOS 2024 onwards, the relevant last assignment is used. The individual deed and Government lease determine the precise calculation. The historical cash discount, outstanding mortgage, expected rent and nearby asking prices are not substitutes for HA's assessment.
For an arithmetic illustration only, suppose the deed records an initial market value of HK$5,000,000 and an original purchase price of HK$3,000,000. The discount is (HK$5,000,000 − HK$3,000,000) ÷ HK$5,000,000 = 40%. If the prevailing unrestricted value were HK$6,000,000, the indicative premium would be HK$6,000,000 × 40% = HK$2,400,000. These assumptions explain the method; they are neither HA's assessment of a flat nor a live quote. Obtain the formal assessment before committing funds or a tenancy.
Put the assessment before the tenancy commitment
After confirming the restriction and assembling the assignment details, apply to HA for a premium assessment. Plan for the assessed lump sum, any application fee and the time needed to complete payment. Expected rental receipts cannot be treated as premium already paid. HA says an owner must pay the premium in full to remove alienation restrictions before selling, letting or otherwise alienating the flat on the open market.
Set the proposed lease and handover date after obtaining the formal evidence that payment and removal of restrictions have taken effect. If the flat is mortgaged, check the loan documents for any letting condition too. Then prepare a separate rental budget for management charges, possible vacant periods and repairs. Those operating costs affect whether letting is worthwhile, but they do not alter the premium formula.
- Record the first assignment date, original sale exercise, deed of assignment and Government lease.
- Request HA's formal premium assessment and allow enough cash and time for payment.
- Confirm the premium is paid and the restriction removed before signing an ordinary open market tenancy and handing over keys.
