HDB Flat Eligibility (HFE) Letter: How to Apply, How Long It Takes and the New 2026 Income Ceiling

The HDB Flat Eligibility (HFE) letter answers the three questions that decide an HDB purchase, in one document and before you commit to anything:

Second-timers also see the resale levy or premium they would pay on a subsidised flat. HDB describes the letter as giving you "a holistic understanding of your housing and financing options" so that you can plan a budget before you start (HDB, HFE letter).

You apply online on the HDB Flat Portal with Singpass, and one letter covers everyone in the application: every applicant and every occupier. That is also its main constraint. The people listed when you buy must be the same people listed on the letter.

The HFE letter turns "can we afford a flat?" from a guess into a number.

HDB sets the requirement at the first step of each buying route (HDB, HFE letter):

That settles the questions people ask most:

• Can you apply for a BTO while waiting for your HFE letter? No. For the February 2026 exercise HDB wrote that applicants "will need to have a valid HDB Flat Eligibility (HFE) letter before submitting a flat application." A pending application is not a valid letter. HDB also suspends the HFE application e-Service during each sales exercise's application period, so you cannot start one mid-launch; applications already submitted keep being processed.
• Which flats can you apply for? Only the flat types your approved letter says you are eligible for.
• Can you buy an HDB flat without one? Not from HDB, and not on the resale market either, because you must hold a valid letter before you obtain an OTP from the seller. If you are borrowing from a bank, HDB also requires a valid Letter of Offer from the bank before you exercise the OTP.
• What if the letter expires after you have applied? You can carry on. HDB says you "may proceed with the flat purchase even if the HFE letter has since expired", because your application is processed on the letter you submitted with it.

No letter, no application, and no OTP.

The increase was announced at the National Day Rally and set out in HDB's release of 23 August 2026, the first change since the ceilings were last adjusted in 2019. It applies to anyone who applies for an HFE letter from 24 August 2026 to buy a new subsidised flat, buy a resale flat with the CPF Housing Grant, or take an HDB housing loan (HDB, 23 Aug 2026).

The executive condominium ceiling rose too, to $18,000, but only for new units in ECs whose land tender closed on or after 24 August 2026. Balance units in existing ECs stay at $16,000.

One more line in HDB's table matters: there is no income ceiling for buying a resale Unclassified or Standard flat without the CPF Housing Grant. For those flats the ceiling only matters if you want the grant or an HDB loan. Resale Plus and Prime flats carry the ceiling either way.

If you already hold a letter, HDB's Annex B sets out what happens:

• You were already eligible: nothing to do. The change does not affect you.
• Your letter says you earned too much under the old ceiling: if you have not submitted a flat application, you may cancel the letter and apply for a new one. Your 12-month income window then runs from the date of the new application.
• Your application was still being processed on 24 August: it is assessed under the old ceiling. To be assessed under the new one, cancel it and submit a new application.

The November 2026 BTO exercise (as at 18 September 2026). HDB moved its next BTO exercise from October to November 2026 so buyers had time to apply under the new ceilings, and encouraged anyone who wants to take part to "apply for an HFE letter early and submit all required documents by 25 September 2026". About 7,960 flats in Bedok, Geylang, Sembawang, Tengah, Toa Payoh and Yishun are planned for that exercise.

A higher ceiling only helps you if your letter was assessed under it.

The whole process runs on the HDB Flat Portal (HDB, HFE letter):

1. Get everyone's Singpass ready. All applicants and required occupiers need a valid Singpass account.
2. Step 1: Check Preliminary HDB Flat Eligibility. You declare your household, citizenship, property and income details and get a preliminary outcome.
3. Step 2: Apply for the HFE letter within 30 calendar days of Step 1. HDB asks you to finish both steps in the same calendar month if you can; otherwise you must update the employment and income details of everyone listed.
4. Let Myinfo fill in what it can. HDB retrieves what it can through Myinfo, but it may still ask for supporting documents, by SMS and email.
5. Wait for the outcome. HDB sends an SMS and email when the letter is ready.

To check your status or read your letter: log in to the Flat Portal and go to My Flat Dashboard > Applying an HDB Flat Eligibility (HFE) letter > Step 2 - Apply for HDB Flat Eligibility (HFE) Letter > View Letter. Document requests show up on the same path under Upload Documents.

Two rules catch people out. You cannot edit an application once Step 2 is submitted: apart from updating your contact details, any change means cancelling it and applying afresh. And the applicants and occupiers in your eventual flat application must be exactly the ones on the letter. If you want a bank loan instead, you can request an in-principle approval from participating banks in the same application, free of charge.

Two eligibility points come before Step 1. Singapore Citizen singles who are unmarried or divorced can apply from age 35. And if you already own an HDB flat, you and your core occupiers can apply only after meeting the Minimum Occupation Period on it.

For a checklist of what to gather before Step 1, see our guide on what to prepare before you apply.

Settle who is on the application before Step 1, because you cannot change it after Step 2.

HDB's own answers (HDB, HFE letter):

The month runs from the day HDB has every document, not from the day you press submit, so a missing payslip adds to the wait. If you are aiming at a particular launch, work backwards from its application window; the Property Timeline Planner lays out the steps after that.

The clock starts when HDB has every document, not when you click submit.

HDB counts the income of all persons listed, applicants and occupiers, to decide whether your household can buy a flat, receive grants and take an HDB loan (HDB, income guidelines).

• The window. 12 months, ending two months before the month of your application. HDB's example: apply in May 2024 and the window runs from April 2023 to March 2024.
• The average. Each person's income is divided by the months they actually worked in that window. Months on no-pay leave count as unemployment, and someone who started work mid-window is averaged from their start date. Self-employed income is averaged over 12 months, or from when the business started.
• Occupiers. Their income counts towards the household ceiling, but not towards the credit assessment for an HDB loan. Only applicants' incomes support the loan.

Once the letter is issued, a pay rise will not raise it. HDB says that during the 9-month validity "the EHG and housing loan amounts will not be reviewed, even though there may be subsequent income increases"; to be considered for more, you cancel the letter and apply again, which also moves the 12-month window to the new application date. The loan can still go down. If your ability to repay worsens, HDB says "the loan amount may be reduced", and for an uncompleted flat it reviews your finances again nearer completion, before it disburses the loan.

HDB looks at the past year's pay, not next month's raise.

HDB's income guidelines tie two items to being in work (HDB, income guidelines):

• "You must be working at the point of the HFE letter application to be considered for an Enhanced CPF Housing Grant and HDB housing loan."
• "Applicant(s) taking an HDB housing loan must remain in their employment or trade when HDB disburses the housing loan."

HDB's employment status guide for the form includes an "Unemployed" option, for someone who "did not work during the entire 12-month assessment period". What HDB ties to being in work is the grant and the HDB loan.

The Enhanced CPF Housing Grant goes further. You or a core member "must have worked continuously for at least 12 months, 2 months before the HFE letter application" and be working when you apply. If you have just started a job, HDB averages your income over the months you have worked, so a recent start does not dilute your average, but the EHG's 12-month condition may not be met yet. HDB will not add the EHG to a letter that is already valid: you would have to cancel it and apply again once you qualify.

If you are self-employed, expect to be asked for more documents, and remember that the averaging runs over 12 months or from when your business started. HDB also says you do not need to opt for its Deferred Income Assessment in the HFE application; if you are eligible, you are told when you book a flat. If you plan to borrow from a bank instead, its in-principle approval is a separate assessment; see what an IPA is.

Check the 12-month work condition before you apply, not after the letter arrives.

Many buyers still search for "HLE". What they need now is the HFE letter:

Source: HDB releases of 28 April 2023, 8 May 2023 and 4 November 2023.

HDB's reason for the switch was certainty: under the old process, eligibility for the flat and the grants had "yet to be confirmed" when buyers applied or secured a resale flat. The HFE letter also standardised the income assessment to 12 months, "instead of the most recent three or six months". In its first six months HDB processed more than 65,000 HFE applications and issued 60,600 letters.

If you are reading an older guide that tells you to "get your HLE first", read it as "get your HFE letter first". Our earlier article on preparing an HLE or HFE application covers the paperwork side.

HLE asked "can you borrow?". HFE asks "can you buy, with what help, and how much can you borrow?"

The loan figure in your letter is a ceiling. To see what it has to cover, we set HDB's 75% loan-to-value limit against what resale flats actually sold for in the first half of 2026:

Source: PropKaki analysis of HDB resale registrations, national medians for January to June 2026 (2026 H1); the 75% limit is HDB's. Medians are across all towns, and a particular flat can cost much more or less.

The 25% column is before stamp duty, legal fees and any cash over valuation, which come on top. Several HDB rules can also put your loan below that column (HDB, housing loan):

• Price or value, whichever is lower. On a resale flat HDB lends up to 75% "of the lower of the resale price or value of the flat", so paying above valuation comes out of your pocket.
• Your income and record. Repayments are capped at 30% of your monthly income (the mortgage servicing ratio; see how the MSR limits your HDB loan). HDB sizes the loan at the higher of a 3.0% interest-rate floor and its prevailing rate, and weighs your age, job stability, existing loans, past repayment record and monthly cash savings.
• Age and lease. The repayment period is capped at the shortest of 25 years, 65 minus your average age, or the remaining lease minus 20 years, and the 75% is pro-rated down if the remaining lease does not cover the youngest buyer to age 95.
• Your CPF. You may keep up to $20,000 in your Ordinary Account; the rest must go into the purchase before HDB grants the loan.
• A second look. On an uncompleted flat, HDB reviews your finances nearer completion, and the loan can be reduced if your position has worsened.

Your letter itself shows three HDB loan amounts: Prudent, Moderate and Maximum. You can take any amount up to the Maximum, subject to the loan-to-value limit, but HDB points out that "a bigger housing loan or longer repayment period will increase your interest costs".

Grants then reduce the 25% you fund yourself. To see your own figures, with your income, grants and the flat you are looking at, run them in the Property Financial Planner.

The loan in your letter is a ceiling, not a budget.

Official rules. Every rule on this page comes from HDB's own pages: the HFE letter application page and its frequently asked questions, the income guidelines and employment status guide for the HFE letter, the Housing Loan from HDB and Option to Purchase pages, the frequently asked questions on sales exercises, the February 2026 BTO and SBF release and its administrative details, HDB's 2023 releases introducing the HFE letter and extending its validity, and HDB's 23 August 2026 release on the new income ceilings with its Annex A (the ceilings) and Annex B (existing letters). We read them in August and September 2026. HDB changes these rules; check hdb.gov.sg before you rely on them.

Proprietary figures. The median resale prices are PropKaki's analysis of HDB resale registrations: national medians by flat type for January to June 2026, the latest half-year with a complete sample (5,379 4-room resales). The half-year still being lodged is excluded. The loan and downpayment columns apply HDB's 75% loan-to-value limit to those medians. How we compute figures across the site: PropKaki methodology.

What we have not claimed: your own eligibility, grant amounts or loan, which HDB assesses in your HFE letter and can review; that a median price is what any particular flat costs; or the outcome of any application. This is a practical explainer, not legal or financial advice.
