A resale HDB flat offers a known location, a home that can be inspected and a faster move than a construction wait. It can also require much more cash than the listing suggests.
The safe sequence is HFE, budget, inspection, official Option to Purchase, HDB value, confirmed finance, exercise, resale application and completion. Keep cash for the deposit, any cash over valuation and expenses CPF cannot cover.
Who may buy a resale HDB flat?
Buyers must qualify under an HDB scheme and remain eligible until completion. Common routes include a family nucleus, an unmarried citizen aged at least 35 buying alone or with eligible joint singles, and an all-PR family where the relevant core members have generally held PR status for at least three years.
A single PR cannot ordinarily buy alone. The Ethnic Integration Policy or SPR quota can also block a specific address even when the household itself qualifies.
An ordinary, non-subsidised open-market resale purchase generally has no overall income ceiling if it uses neither an HDB loan nor a CPF housing grant. Income limits still matter for loans, grants and resale Plus or Prime flats. The HFE letter is the authoritative answer for the actual household.
The 2026 change for private-property owners
From 28 July 2026, HDB removed the former 15-month wait-out period for private residential property owners and former owners who buy a non-subsidised resale HDB flat without an HDB loan.
A buyer who still owns residential property must dispose of the relevant Singapore and overseas interests within six months after completing the HDB purchase. The 30-month wait continues when seeking subsidised housing, including BTO/SBF, a resale grant, a new EC or an HDB loan. Plus and Prime resale flats also have tighter conditions.
The HDB change does not cancel ABSD. Some HDB buyers who must dispose of an existing property may qualify for an upfront ABSD remission under specific IRAS conditions. Check HDB eligibility, the remission rules and IRAS property-count treatment separately before accepting an option.
Step 1: HFE; step 2: inspect the flat and records
An HFE letter is free, normally valid for nine months and shows resale eligibility, CPF housing grants, any HDB loan and the approved household. It must be valid before the seller grants the HDB Option to Purchase and when the resale application is submitted.
A bank borrower also needs a valid Letter of Offer before exercising the option. In-principle approval helps with planning but is not the final loan.
Use HDB’s Flat Portal and official resale-price records to compare the town, flat type, floor range and remaining lease. During the viewing, inspect:
- remaining lease and how it affects financing and CPF;
- water leaks, concrete, windows, electrical load and air-conditioning;
- non-standard walls, platforms or possible unauthorised work;
- lift access, afternoon sun, road noise and estate works;
- renovation needed before occupation and pending upgrading charges;
- seller requests for a temporary extension of stay.
A property generally needs more than 20 years of remaining lease before CPF can be used. If the lease does not cover the youngest CPF user to age 95, the usable amount may be prorated.
Step 3: HDB OTP; step 4: Request for Value
Only HDB’s prescribed OTP should be used. The seller may charge S$1 to S$1,000 as the option fee, payable in cash. The option lasts 21 calendar days, including weekends and public holidays, and expires at 4pm on the final day. The seller cannot grant another option during that period.
If CPF or a housing loan will be used, submit the S$120 Request for Value by the next working day after the OTP is granted. Loan and CPF use are generally based on the lower of agreed price and HDB value. The difference above value is cash over valuation and must be cash-funded.
Do not exercise and hope the value matches later. An exercised option is binding, and the full COV cannot be financed or paid from CPF.
To exercise, pay the exercise fee in cash. Option and exercise fees together cannot exceed S$5,000. This deposit forms part of the purchase price; it is not an extra S$5,000 cost.
Step 5: submit the resale application
After exercise, buyer and seller submit their parts. HDB must receive them within seven calendar days of each other or the application is cancelled without fee refund.
| Flat | Buyer’s resale application fee |
|---|---|
| 1- or 2-room | S$40 |
| 3-room or larger | S$80 |
HDB generally communicates acceptance within 28 working days after receiving a complete application and documents. The earliest completion is normally about eight weeks after acceptance.
Loan, valuation and the complete cost stack
| Financing | Maximum in the stated arrangement | Buyer-funded portion | Minimum cash component |
|---|---|---|---|
| HDB loan | 75% | 25% | No fixed minimum beyond cash-only items |
| Bank loan at 75% LTV | 75% | 25% | 5% |
| Bank loan at 55% LTV | 55% | 45% | 10% |
The actual loan can be lower. The deposit is part of the buyer-funded portion; COV is additional cash caused by price exceeding value.
Worked S$600,000 purchase
Assume HDB value is S$580,000 and an HDB loan reaches 75% of that value. The loan is S$435,000, the value-based 25% portion is S$145,000 and COV is S$20,000. The total not covered by the loan is S$165,000. A cash deposit of up to S$5,000 is already inside that total.
BSD on S$600,000 is S$12,600: S$1,800 on the first S$180,000, S$3,600 on the next S$180,000 and S$7,200 on the remaining S$240,000.
| Additional line | Treatment |
|---|---|
| ABSD | Status, property count and remission determine it |
| Request for Value | S$120 including GST when required |
| Application | S$40 or S$80 |
| Legal, conveyancing and registration | HDB scale or current private-solicitor quote |
| Property tax and S&CC | Apportioned or arranged at completion |
| Insurance | HDB fire insurance is required while an HDB loan remains outstanding |
| Renovation and repairs | Often the largest amount absent from the listing |
CPF Board cites roughly S$2,500–S$3,000 as an average private legal-cost estimate for a bank-financed HDB purchase. It is not a fixed tariff; obtain a quotation.
Headline grant maxima require several conditions to align
| Grant | Eligible family | Eligible single buying alone |
|---|---|---|
| CPF Housing Grant, 2- to 4-room resale flat | Up to S$80,000 | Up to S$40,000 |
| CPF Housing Grant, 5-room or larger | Up to S$50,000 | Up to S$25,000 |
| Enhanced CPF Housing Grant | Up to S$120,000 | Up to S$60,000 |
| PHG when living with parents or child | S$30,000 | S$15,000 |
| PHG when living within 4km | S$20,000 | S$10,000 |
The maximum combined headline can reach S$230,000 for a family or S$115,000 for a single only where every scheme condition and top tier aligns. EHG still uses income ceilings of S$9,000 for a family and S$4,500 for a single despite the higher 2026 general ceilings. PHG has no income ceiling but has proximity, occupancy and prior-usage rules.
Grants are credited to CPF, not paid as cash. Grant amounts and accrued interest generally return to CPF when the flat is sold.
MOP follows the flat classification
| Resale flat | New owner’s MOP | Whole-flat rental |
|---|---|---|
| Existing unclassified flat | Generally 5 years | Possible after MOP, subject to rules |
| Standard | 5 years | Possible after MOP, subject to rules |
| Plus | 10 years | Never permitted |
| Prime | 10 years | Never permitted |
MOP generally begins at resale completion. During it, owners must occupy the flat and generally cannot sell it, rent out the whole flat, buy other residential property or apply for another HDB flat or new EC. Special schemes can impose different periods.
The resale levy is not a fee for buying resale
An ordinary open-market resale purchase does not itself trigger a resale levy. The levy generally matters when a household that has enjoyed one housing subsidy later buys a second subsidised HDB flat or certain new ECs.
A first subsidy can be a flat bought from HDB, an EC bought from a developer or a resale flat bought with a CPF housing grant. A household can sell a subsidised BTO and buy ordinary resale without a grant without a levy on that resale purchase, while the same household considering another BTO should check the levy.
| First subsidised flat | Household levy | Singles Grant recipient |
|---|---|---|
| 2-room | S$15,000 | S$7,500 |
| 3-room | S$30,000 | S$15,000 |
| 4-room | S$40,000 | S$20,000 |
| 5-room | S$45,000 | S$22,500 |
| Executive | S$50,000 | S$25,000 |
| Executive Condominium | S$55,000 | Not applicable |
These fixed amounts apply to common post-3 March 2006 cases. Older cases, special schemes and household changes can differ. Obtain the actual levy from HDB.
Five checks before exercising the OTP
- The HFE is valid and matches the intended household.
- The HDB loan is confirmed or the bank Letter of Offer is secured.
- HDB value is available and cash-only COV is affordable.
- Remaining lease, CPF limits, EIP/SPR quota and classification have been checked.
- Stamp duty, legal costs, renovation and emergency cash remain funded after completion.
The 21-day option period is time for these checks, not a race to transfer the exercise fee.
