The HDB Flat Eligibility (HFE) letter is the single application that tells you three things before you commit to a flat: whether you can buy a new or resale HDB flat, how much in CPF housing grants you qualify for, and how large an HDB housing loan you can take, including the dollar amount. It replaced the old HDB Loan Eligibility (HLE) letter from 9 May 2023 and folded several separate eligibility checks into one process on the HDB Flat Portal. You apply with Singpass, it pulls your data through Myinfo, processing takes about a month after your documents are in, and the letter stays valid for nine months. You need a valid HFE letter before you can apply for a BTO flat, get an Option to Purchase on a resale flat, or submit a resale application.
An HFE letter is HDB's combined verdict on your flat purchase. Instead of three separate answers from three separate processes, you get one assessment that confirms what you can and cannot do as a buyer.
The letter spells out three outcomes. None of them is a vague yes or no; each comes with the specifics you need to plan your budget.
Before May 2023, buyers ran several checks at different points. You had an HDB Loan Eligibility (HLE) letter for the loan amount, separate flat eligibility checks, and a separate grant assessment. People often found out late that they did not qualify for a grant they had counted on, or that their loan was smaller than expected, after they had already set their hearts on a flat.
From 9 May 2023, HDB introduced the HFE letter to replace the HLE letter and consolidate those assessments into one application on the HDB Flat Portal. The point is to give you a single picture of your housing and financing options before you start, rather than piecing it together as you go. The trade-off is that the HFE is more involved than the old HLE, because it now assesses grants and flat eligibility too, not just the loan.
If you are weighing a new flat against a resale unit while you wait, the BTO buying guide and the BTO vs resale comparison cover the trade-offs in detail.
You apply for the HFE letter early, before you make any binding move on a flat. HDB treats it as a prerequisite for the steps that lock you in.
Because processing takes about a month and the letter is valid for nine months, the sensible move is to apply well ahead of the sales exercise or your resale search. If you wait until the launch is open, you risk missing the application window. A nine-month validity gives you room to hunt for a resale flat or sit through a couple of BTO exercises on the strength of one letter.
The whole application runs through the HDB Flat Portal. You log in with Singpass, and the form pulls most of your details through Myinfo so you fill in less by hand. There are two steps, and they must be completed within 30 calendar days of each other.
The first step is a preliminary check. You enter your household particulars, add co-applicants and any occupiers, declare your employment and monthly income, and declare any interest in private property, local or overseas. You also indicate whether you intend to take an HDB loan or a bank loan. This step gives you an early read on your eligibility before you commit to the full submission.
The second step is the actual application. You confirm your loan choice, pull additional details through Myinfo, review everything for accuracy, upload any supporting documents the portal asks for, and submit. Your draft from Step 1 stays valid for 30 calendar days, so finish Step 2 inside that window or you start over.
If you tell the portal you intend to take a bank loan, this is also where you can request an In-Principle Approval (IPA) from a participating bank. The IPA is the bank's own indication of how much it will lend you, and it sits alongside the HFE letter rather than replacing it. You still need the HFE letter to buy, but pairing it with an IPA lets you compare what HDB will lend against what a bank will lend before you sign anything. Banks usually offer IPAs free and valid for a set window, so time the request close to when you plan to commit.
If you are comparing an HDB loan against a bank loan at this stage, the HDB loan vs bank loan comparison lays out the interest rate and flexibility differences, and you can size your repayments with the HDB loan calculator.
Myinfo handles most of the data, but it does not have everything, so HDB may still ask for documents. You are told by SMS and email if you need to upload anything, and the exact list depends on your circumstances, such as your employment type and household composition.
Common items HDB requests include your CPF contribution history and your Notices of Assessment from IRAS. You may be asked for CPF contribution history covering the last 15 months, even for months in which you received no CPF contributions. Self-employed buyers and those with variable income usually face more document requests than salaried employees whose records sit cleanly in Myinfo. Have your Notice of Assessment and CPF statements ready so you do not stall the clock.
When the portal asks for documents, the file rules are strict enough to trip people up at submission. Each file has to be PDF, JPG or PNG, and it cannot be password-protected or encrypted. Any one file can be up to 5MB, and all your files together can total up to 40MB. Scan or photograph documents in advance and check the file sizes so you are not compressing files at the last minute while the 30-day clock runs. HDB may be unable to process the application until the full set of documents is in, so a missing payslip can stall everything.
Your loan amount and grant eligibility both hinge on your assessed household income, so it helps to know how HDB works it out. HDB takes your average gross monthly household income over a 12-month period that ends two months before the month you apply. The income of every applicant and occupier listed in the application counts.
The figure HDB uses is gross income including your own CPF deductions, but excluding the employer's CPF contributions and bonuses. The 12-month average smooths out months of high or low pay, which matters if your income swings, such as commission or freelance work. If your income or household changes after the letter is issued, the assessment can be reviewed.
A worked example makes the window clear. Apply in June 2026 and HDB assesses your average gross monthly income from April 2025 to March 2026, the 12 months ending two months before your application month. If you only worked part of that window, HDB averages over the months you actually earned income. This is why a recent pay rise barely moves your assessed figure, while a new job in the back half of the window can drag your average down.
Income ceilings still apply on top of this. For a BTO or Sale of Balance flat, the family household income ceiling is $14,000 a month, and for a 2-room Flexi flat a single Singapore Citizen faces a $7,000 ceiling. The Enhanced CPF Housing Grant has its own tighter ceilings, covered below. Confirm the figure for your flat type on the cited HDB income guidelines page before you apply, since these are reviewed periodically.
The HFE letter is where you find out your real borrowing power and your grant entitlement, not estimates. Two figures drive your cash planning.
For HDB housing loans granted on or after 20 August 2024, the maximum Loan-to-Value (LTV) limit is 75% of the purchase price or valuation, whichever is lower. That means at least 25% of the price has to come from CPF or cash. Your actual loan offer in the HFE letter can be lower than 75% once HDB applies the loan rules, including the income-based limits. The loan-to-value ratio, Mortgage Servicing Ratio and Total Debt Servicing Ratio all shape the final number.
First-timer families can receive up to $120,000 in Enhanced CPF Housing Grant (EHG), and eligible Singles up to $60,000, with the amount scaling down as household income rises. The EHG income ceilings are $9,000 a month for families and $4,500 for Singles. For resale flats, first-timer Singapore Citizen families can get a CPF Housing Grant of up to $80,000 and Singles up to $40,000, on top of any EHG and Proximity Housing Grant they qualify for. The full grant stack is set out in the HDB housing grants guide.
Second-timers get one extra line in their HFE letter that first-timers never see: the resale levy. If you took a housing subsidy on a flat before, whether a new flat, a resale flat bought with a CPF housing grant, or an Executive Condominium from a developer, and you buy a second subsidised flat, you pay a resale levy to even out the subsidy you have already had. The HFE letter flags the amount up front so it does not ambush your budget.
For households that sold their first subsidised flat on or after 3 March 2006, the levy is a fixed sum tied to the flat type you sold, not a percentage. Singles who bought under the Single Singapore Citizen Scheme pay half of these figures. The levy is normally paid from the sale proceeds of your first flat when you collect the keys to your second one. If you are splitting ownership instead of moving up, the decoupling route has its own rules and costs.
| First subsidised flat sold | Resale levy (household) | Resale levy (single) |
|---|---|---|
| 2-room | $15,000 | $7,500 |
| 3-room | $30,000 | $15,000 |
| 4-room | $40,000 | $20,000 |
| 5-room | $45,000 | $22,500 |
| Executive flat | $50,000 | $25,000 |
After you submit, you do not have to keep guessing. HDB tells you by SMS and email if it needs more documents, and you can check progress yourself on the HDB Flat Portal. Log in with Singpass and open My Flat Dashboard, then go to the home-seeker section for HFE letter applications and view the status of your Step 2 submission. Once the letter is issued, the same dashboard is where you view and download it.
Watch your inbox and SMS during the wait. A document request that sits unanswered is the most common reason an HFE letter drags past the one-month mark, because HDB cannot finish the assessment until the file is complete. If you switch jobs, get married, or your household changes while the application is in progress, flag it, since it affects the income assessment and the grant and loan figures the letter will carry.
Once HDB has your completed application and full set of documents, processing takes about a month, which works out to roughly 21 working days. It can run longer just before and during a sales exercise, when application volume spikes, so do not bank on the fastest case if a launch is near.
The HFE letter is valid for nine months from the date of issue. HDB extended the validity from six months to nine months with effect from 7 November 2023, giving buyers more breathing room to find a flat. If your letter lapses before you buy, you reapply. If your circumstances change during the validity period, such as income, household members, or property ownership, HDB can review and revise the assessment, so keep your details current.

With the HFE letter in hand, you can act. For a new flat, you can apply during a BTO or Sale of Balance Flats exercise or book under open booking. For a resale flat, you can accept an Option to Purchase from a seller and later submit your resale application to HDB.
Treat the numbers in the letter as your budget ceiling, not your target. The loan amount is the most you can borrow on an HDB loan, and borrowing the maximum stretches your monthly repayment and your CPF Ordinary Account. Map the loan and grant figures against your down payment, stamp duty and renovation cash before you commit. The BTO affordability calculator turns the letter's loan and grant figures into a realistic price range, while the mortgage calculator and stamp duty calculator fill in the full cash picture, and the property planning guide ties it together.
It is HDB's combined assessment that tells you whether you can buy a new or resale HDB flat, how much in CPF housing grants you qualify for, and how large an HDB housing loan you can take, including the dollar amount. You apply for it on the HDB Flat Portal using Singpass before you commit to any flat.
No. The HFE letter replaced the HDB Loan Eligibility (HLE) letter from 9 May 2023. The old HLE letter only covered your loan amount, while the HFE letter also assesses your flat eligibility and your CPF housing grant entitlement in a single application.
About a month, or roughly 21 working days, after HDB receives your completed application and full set of documents. It can take longer just before and during a sales exercise because of high application volume, so apply early.
Nine months from the date of issue. HDB extended the validity from six to nine months on 7 November 2023. If it lapses before you buy, you reapply, and if your circumstances change during the validity period HDB may review the assessment.
Yes. You need a valid HFE letter before a resale seller can grant you an Option to Purchase, and before you can submit your resale application to HDB. Apply for it early in your flat search rather than after you have found a unit.
Myinfo retrieves most of your details, but HDB may still ask for documents such as your CPF contribution history (sometimes the last 15 months) and your Notices of Assessment from IRAS. You are notified by SMS and email if you need to upload anything, and the list depends on your employment type and household.
HDB takes your average gross monthly household income over a 12-month period ending two months before you apply, counting every applicant and occupier in the application. It uses gross income including your own CPF deductions, but excludes employer CPF contributions and bonuses.
No. A valid HFE letter is required before you apply for a flat in a BTO or Sale of Balance Flats exercise, or book under open booking. Since processing takes about a month, submit your application before the launch you are targeting.
Yes, if you have owned a subsidised flat before. The HFE letter states the resale levy you will owe on a second subsidised flat. For households that sold their first flat on or after 3 March 2006, the levy is fixed by flat type sold, from $15,000 for a 2-room up to $50,000 for an Executive flat, with singles paying half. First-timers pay no resale levy.
No. The HFE letter is HDB's assessment of your flat eligibility, grants and HDB loan, and you need it to buy. An In-Principle Approval (IPA) is a bank's indication of how much it will lend you. If you plan to take a bank loan, you can request an IPA during Step 2 of the HFE application and use it to compare the bank's offer against an HDB loan.
Log in to the HDB Flat Portal with Singpass and open My Flat Dashboard, then go to the home-seeker section for HFE letter applications to view your Step 2 status. HDB also notifies you by SMS and email if it needs more documents, and once the letter is issued you view and download it from the same dashboard.
