The HDB Resale Process in 2026: A Step-by-Step Guide

Buying a resale flat is a sequence, and the order matters. Offer before your financing is confirmed, or exercise before valuation, and you either lose your deposit or lose the flat. Each step below comes with its fees and its waiting time.

Step 1: Get your HFE letter before anything else

The HDB Flat Eligibility (HFE) letter is the gate to every later step: it confirms your eligibility to buy, the housing grants you qualify for, and the HDB loan amount you can take.

Three things to know:

• Processing takes up to 21 working days once HDB has your documents, roughly a month in practice. Apply before you start serious viewings.
• It is valid for 9 months, which comfortably covers a typical search.
• Sellers (and their agents) will ask for it. Without a valid HFE letter, a seller cannot legally grant you an Option to Purchase.

If you plan to use a bank loan instead of an HDB loan, get your bank's In-Principle Approval (IPA) at the same time. An IPA typically holds for about a month, so time it against your viewing schedule.

Step 2: Work out your true budget

Your budget is the sum of four parts, and only one of them is the loan:

Component	Where it comes from
Loan	HDB loan (up to 75% of price or valuation, whichever is lower) or bank loan (up to 75%)
CPF	Ordinary Account savings, less any amounts you must set aside
Cash (required)	Option + exercise fees (max $5,000 combined); 5% minimum cash downpayment if taking a bank loan
Cash (buffer)	Stamp duty shortfalls, renovation, the "cash over valuation" gap if you offer above the flat's valuation

Since August 2024 the HDB loan-to-value limit has been 75%, the same as bank loans; the old 80% HDB advantage is gone. The full mechanics of using your CPF, including the accrued-interest catch most buyers miss, are in our guide to using CPF for property.

Watch the cash-over-valuation gap: if you offer $620,000 for a flat that HDB later values at $600,000, the $20,000 difference is payable in cash. Neither your loan nor your CPF can touch it.

Step 3: Search, view, and check the flat's history

Beyond the usual (floor level, orientation, remaining lease), pull the transaction history for the block and its neighbours from the HDB resale statistics before you form a number. Recent transacted prices for the same stack beat any listing price as evidence.

Check the remaining lease against your age: CPF usage and loan limits tighten when a flat's lease cannot cover the youngest buyer to age 95.

Step 4: Option to Purchase, where $1,000 buys you 21 days

When you agree on price, the seller grants you an Option to Purchase (OTP) in exchange for an option fee of up to $1,000 in cash.

You now have 21 calendar days to decide. Use them for two things:

1. Valuation. Submit a Request for Value to HDB on the next working day. This fixes the number your loan and CPF calculations are based on.
2. Financing. Convert your IPA into a formal loan offer, or confirm your HDB loan against the HFE letter.

To proceed, you exercise the option by paying the exercise fee. The option fee and exercise fee together are capped at $5,000, all cash. To walk away, do nothing and forfeit the option fee. Treat the forfeited $1,000 as insurance: walking away from a bad flat costs far less than buying one.

Step 5: Submit the resale application

Both buyer and seller submit their portions through the HDB Resale Portal, within 7 days of each other. From acceptance, HDB's processing runs about 8 weeks to completion. During this window HDB verifies eligibility, lawyers (HDB's or your own) do title checks, and you receive the approval letter with your completion appointment date.

Budget for the transaction costs that land in this window:

• Buyer's Stamp Duty: tiered, payable within 14 days of exercising; can be paid from CPF for HDB flats (with a cash-first-then-refund flow in some cases)
• Conveyancing fees: a few hundred to around two thousand dollars depending on whether you use HDB's lawyers
• Home Protection Scheme premium if using CPF for an HDB loan

Step 6: Completion day

At the completion appointment (at HDB Hub or your lawyer's office), the balance of payments moves, ownership transfers, and you collect keys. Do the final inspection before the appointment, confirming the flat is vacated and in the agreed state, because after completion you have little leverage to fix problems.

The realistic timeline, end to end

Phase	Time
HFE letter	up to 21 working days
Search and negotiation	2 weeks – 3 months (yours to control)
OTP to exercise	up to 21 days
Resale application to completion	~8 weeks
Total	roughly 3–5 months

If you are selling a flat to fund this purchase, the sequencing question (sell first or buy first) reshapes your timeline and your tax bill. We work through that decision in Should You Sell Your HDB Before Buying a Condo?, and the same logic applies to flat-to-flat moves.
