What the HDB Concessionary Loan Is
The HDB concessionary loan is a home loan provided directly by HDB to eligible buyers of HDB flats. As at Q2 2026, the interest rate is 2.6% per annum (pegged at 0.1% above the CPF Ordinary Account interest rate of 2.5% p.a.). This rate is typically lower than bank loan rates during periods of elevated market interest rates, making it an attractive option for buyers who qualify.
However, the HDB loan is not available to all buyers. HDB sets specific eligibility criteria that must be met at the time of flat application and at the time the loan is drawn down. Failure to meet any criterion disqualifies the buyer from the HDB loan and requires them to use a bank loan instead.
HDB Loan Eligibility Criteria
1. Citizenship Requirement
At least one buyer (applicant) must be a Singapore Citizen. Households consisting entirely of Singapore Permanent Residents (SPRs) are not eligible for an HDB loan — they must use a bank loan for their HDB resale flat purchase.
2. Income Ceiling
The household gross monthly income must not exceed the applicable income ceiling at the time of application:
| Flat Type / Application Type | Income Ceiling (Q2 2026) |
|---|---|
| HDB BTO flat (families) | $14,000 per month |
| HDB resale flat (families) | $14,000 per month |
| Singles buying 5-room or smaller resale flat | $7,000 per month |
| Joint Singles Scheme (2–4 singles buying together) | $14,000 per month combined |
Income is assessed as the average gross monthly income over the preceding 12 months. This includes base salary, commissions, overtime, and allowances. Self-employed applicants are assessed on their net trade income as declared to IRAS.
3. No Current Private Residential Property Ownership
No applicant in the household may own, or have disposed of, any private residential property in Singapore or overseas within the 30 months before the flat application. This is the key restriction that disqualifies upgraders who have recently sold a private property.
Specifically:
- Applicants who currently own a private property are ineligible for an HDB loan
- Applicants who disposed of a private property within the last 30 months are also ineligible — the 30-month wait-out period must have elapsed
- This restriction applies to both local and overseas private residential property
4. Credit History: No Adverse Credit Assessment
HDB assesses the applicant’s credit standing through the Credit Bureau Singapore (CBS). Applicants with a significantly adverse credit history — including defaults, outstanding judgments, or declared bankruptcy — may be disqualified from the HDB loan.
Applicants who have been discharged from bankruptcy may still qualify, subject to HDB’s assessment. HDB evaluates each case individually and may impose conditions.
5. Previous HDB Loan History
Applicants who have previously taken 2 or more HDB concessionary loans are no longer eligible for a third HDB loan. The HDB loan can be used at most twice in a lifetime:
- First HDB loan — for the first HDB flat purchase
- Second HDB loan — for a subsequent HDB purchase, subject to resale levy and eligibility
- Third and subsequent HDB purchases — must be financed by bank loan only
The HDB Loan Eligibility Letter (HLE)
Before exercising an OTP or signing a Sales & Purchase Agreement for an HDB flat, buyers who intend to use an HDB loan must obtain an HDB Loan Eligibility (HLE) letter. The HLE letter confirms:
- Whether the buyer is eligible for an HDB concessionary loan
- The maximum loan amount HDB will offer
- The validity period (typically 6 months from issuance)
The HLE letter must be valid at the time the flat application is submitted. Buyers who proceed without a valid HLE and subsequently discover they are ineligible for an HDB loan face significant complications — particularly if they cannot secure adequate bank financing at the required LTV and within the MSR/TDSR limits.
Agent note: Always confirm HLE status before the OTP is issued. A buyer who has not obtained an HLE — or who assumes they qualify without checking — is a transaction risk. The HLE application is free and takes approximately 14 days. Build it into the pre-OTP checklist for every HDB resale transaction where the buyer intends to use an HDB loan.
Maximum Loan Quantum Under HDB Loan
The maximum HDB loan quantum is calculated based on:
- LTV limit: Up to 80% of the lower of the purchase price or valuation for HDB loans (the buyer provides at least 20% in cash and/or CPF)
- MSR cap: Monthly loan repayment must not exceed 30% of the household’s gross monthly income
- Loan tenure: Maximum 25 years or the period until the youngest co-borrower turns 65, whichever is shorter
HDB applies these constraints simultaneously — the maximum loan is the lowest of what the LTV, MSR, and tenure calculation permits.
HDB Loan vs Bank Loan: The Key Trade-Off
For buyers who qualify for both, the choice between an HDB loan and a bank loan involves a rate vs flexibility trade-off:
- HDB loan (2.6% fixed rate): No lock-in period, no early repayment penalty, can refinance to a bank loan at any time — but cannot switch back to an HDB loan once you take a bank loan
- Bank loan (variable or fixed, typically 2%–4.5% p.a. depending on market conditions): Lower rates when market rates are low, but subject to lock-in periods, repricing risk, and a 20% cash floor (vs HDB loan’s allowance of full CPF usage for the down payment)
Refer clients to a mortgage broker or their bank for a full comparison — the rate differential changes with market conditions and LEVR’s Home Loan Calculator can model both scenarios.
Using LEVR to Model HDB Loan Repayments
LEVR’s Home Loan Calculator models monthly repayments and total interest cost for HDB loans at the current 2.6% rate and for bank loans at any rate the agent inputs. Running both scenarios side by side gives buyers a concrete comparison of monthly cash flow under each option — supporting a more informed financing decision.
