Buying a resale flat in Singapore is one of the biggest financial commitments you will make, but does it require a property agent? In 2026, with the streamlined HDB Resale Portal, the answer is increasingly “No.” By handling the transaction yourself, you can save the standard 1% buyer’s agent commissionโa significant sum that can go towards your renovation instead.
However, the DIY route is fraught with administrative pitfalls. From securing the HDB Flat Eligibility (HFE) letter to exercising the Option to Purchase (OTP) correctly, missing a single deadline can cost you the deposit. This guide solves that problem by providing a foolproof, step-by-step roadmap to navigating the HDB resale market on your own.

๐Phase 1: Documents You Must Prepare (Checklist)
Don’t start viewing yet. The most common mistake DIY buyers make is house hunting without paperwork. HDB rules in 2026 strictly forbid sellers from issuing an OTP if you do not have a valid HFE letter.
Use the tabs below to organize your administrative “Ammo” before entering the market.

๐ The HDB Flat Eligibility (HFE) Letter
This is your “Passport” to buying a flat. It replaces the old HLE letter and assesses your eligibility for:
- Flat Purchase: Are you eligible to buy a resale flat?
- CPF Housing Grants: How much subsidy (EHG, PHG, Family Grant) can you get?
- HDB Housing Loan: How much can HDB lend you?
Action Item: Log in to the HDB Flat Portal via Singpass. Processing takes 21 working days. Do not book a viewing until this is approved.
๐ Register Intent to Buy
Once your HFE is ready, you must register an “Intent to Buy” on the HDB Resale Portal.
- Purpose: It triggers an auto-check on your eligibility and the Ethnic Integration Policy (EIP) quotas for your target block.
- Validity: Valid for 12 months.
- Cost: Free of charge.
Warning: The HFE details in your Intent to Buy must match your actual situation when you receive the OTP. If you change jobs, update this!
๐ฐ In-Principle Approval (IPA)
If you are taking a Bank Loan instead of an HDB Loan:
- You must get an IPA from a bank (DBS, OCBC, UOB, etc.).
- This tells you the maximum loan quantum you can borrow.
- Without this, you risk forfeiting your Option Fee if the loan is rejected later.
Cash Planning: Remember you need cash for the Option Fee (S$1,000) and Exercise Fee (S$4,000). These cannot be paid via CPF.
๐Phase 2: Viewing & Negotiation Tactics
Without an agent, you must arrange viewings and negotiate the price yourself. Use these strategies to protect your interests and spot potential “Lemon” units.
๐ Critical Check: EIP & SPR Quota
Before visiting, check the Ethnic Integration Policy (EIP) and Singapore Permanent Resident (SPR) Quota for the specific block.
- If the quota for your race is full, you cannot buy that unit, even if the seller agrees.
- Check updated quotas on the HDB website every 1st of the month.
๐ Price Negotiation
Check Recent Transacted Prices.
Use the HDB Map Services to see the last 3 months of transactions in that block. Never offer blindly.
๐๏ธ Spotting Defects
Look for Water Marks.
Check ceilings for leaks and spalling concrete. Ask the seller if there have been any illegal modifications.
โฑ๏ธ Extension of Stay
Up to 3 Months.
Sellers may ask to stay up to 3 months after completion. Decide if you are willing to delay your move-in.
โจ Negotiation Secrets (Pro Tips)
How to win the deal without overpaying.
๐ Click the floating icons to reveal techniques.
Silence is Gold
When viewing, don’t show too much excitement. Sellers’ agents can sense desperation and will hike the price. Be polite but neutral.
Ask “Why Selling?”
Is it a divorce? Upgrading? Ah Long (Loan shark) issues? The reason can give you leverage. Urgent sellers (e.g., divorce) may accept lower offers.
Inventory List
If the seller promises to leave furniture or air-cons, write it down in the Inventory List attached to the OTP. Verbal promises are useless.
โ๏ธPhase 3: The Transaction Process (Step-by-Step)
This is the technical part where DIY buyers get nervous. Follow this strict chronological order to ensure the deal goes through legally.
Step 1
Issue OTP
Pay Option Fee
Agree on price. Pay the Option Fee (S$1 to S$1,000) to the seller. The seller issues the Option to Purchase (OTP). You now have 21 days (Option Period) to decide.
Step 2
Request Value
Request for Valuation
CRITICAL: By the next working day after OTP Date, you (Buyer) must submit the “Request for Value” on HDB Portal to determine the CPF usage limit.
Step 3
Exercise OTP
Sign & Pay
Once valuation is out and loan is confirmed, sign the OTP acceptance. Pay the Exercise Fee (usually S$4,000, bringing total deposit to S$5,000).
Step 4
Submit App
Resale Application
Both Buyer and Seller must submit the Resale Application on the portal within 7 days of each other. Pay admin fees (S$40 or S$80).
โ ๏ธCritical Warning: The “Cash Over Valuation” (COV) Trap
The most dangerous pitfall for DIY buyers is the COV. If you bid too high, you must pay the difference in CASH.
๐ Understanding COV (Cash Over Valuation)
HDB will only value the flat AFTER you pay the Option Fee. You cannot know the Verified value beforehand.
- Scenario: Seller asks S$600k. You agree. Valuation comes back at S$550k.
- Result: The S$50k difference is the COV.
- Impact: You MUST pay this S$50k in Cash. It cannot be covered by CPF or HDB Loan.
Advice: Always check comparable transaction prices nearby to avoid overbidding blindly.
๐งฎCommission Saver Calculator (How much you save?)
Agents typically charge buyers 1% commission plus GST. See exactly how much cash you are saving by doing it yourself.
Flat Price: S$ 600,000
*Calculation based on standard market rate: 1% Commission + 9% GST.

โFrequently Asked Questions (DIY Problems)
Buying without an agent is empowering but can be confusing. Here are the answers to the most common roadblocks.
Yes, but you can use HDB’s legal services if you are taking an HDB loan, which is cheaper. If you are taking a Bank Loan, you must hire a private conveyancing lawyer (fees range from S$2,500 to S$3,000). The agent doesn’t do legal work anyway.
Absolutely NOT. Under CEA rules, an agent cannot collect fees from both parties in the same transaction. If you represent yourself, the seller’s agent is strictly prohibited from asking you for a commission or “paperwork fee”.
The Option Fee (up to S$1,000) and Exercise Fee (up to S$4,000) must be paid in CASH (or PayNow/Cheque) to the seller directly. You cannot use CPF for the deposit. This amount will be reimbursed to your account upon completion if you have enough CPF funds.
You will forfeit your Option Fee (e.g., S$1,000). The seller keeps the money, and the OTP becomes null and void after 21 days. There are no further penalties, but you lose that cash.
Yes, the new portal guides you step-by-step. However, you must ensure you click “Submit” on time. Missing the 7-day window for the Resale Application submission (after the seller submits) is a common error.
