Step-by-Step Guide to Buying a HDB Resale Flat
Buying a resale HDB flat in Singapore involves multiple steps and eligibility checks. Learn how to navigate the entire process confidently.

For many Singaporeans, buying a resale HDB flat is a practical and flexible housing option. Unlike Build-To-Order (BTO) flats, resale flats are readily available and allow buyers to choose specific locations and flat types. However, the process can be complex for first-time buyers. This guide outlines every key step from eligibility checks to completion so you can make an informed and confident purchase.
Why Choose a Resale Flat?
Resale HDB flats offer distinct advantages over BTO units:
-
Immediate Availability: No waiting time of 3–5 years as with BTO.
-
Mature Estates: You can buy in well-established neighbourhoods with developed amenities.
-
Larger Unit Types: Older flats often come with more spacious layouts.
-
Flexibility: Buyers can negotiate the price and terms directly with sellers.
Step 1: Check Your Eligibility
Before you start viewing flats, you must ensure that you meet the HDB eligibility conditions.
Eligibility Schemes:
-
Public Scheme: Buy with a family member (e.g., spouse, child, parents).
-
Fiancé/Fiancée Scheme: For engaged couples planning to marry.
-
Single Singapore Citizen Scheme: Singles aged 35 and above.
-
Joint Singles Scheme: Two to four single citizens aged 35+.
Citizenship:
-
At least one applicant must be a Singapore Citizen.
-
PRs are allowed to buy resale flats under specific conditions.
Income Ceiling:
-
No income ceiling for buying resale flats unless applying for CPF housing grants.
Step 2: Apply for HDB Flat Eligibility (HFE) Letter
The HFE letter replaces the old HLE letter and includes:
-
Financing assessment
-
Grant eligibility
-
Eligibility to buy a resale flat
You must apply for this letter through the HDB portal and wait for approval before proceeding with your purchase.
Step 3: Browse and View Flats
Use the HDB Resale Portal or real estate platforms to shortlist suitable units. When arranging viewings, consider:
-
Flat condition
-
Location and transport access
-
Proximity to schools, amenities, and workplaces
-
Floor level and facing
-
Lease remaining on the flat
You can also engage a property agent to assist with scheduling and negotiations.
Step 4: Negotiation and Option to Purchase (OTP)
Once you find a flat you like, you can make an offer. If the seller accepts, you proceed to:
Option to Purchase (OTP):
-
You pay $1,000 as an option fee.
-
This gives you 21 days to decide and exercise the OTP.
-
During this time, conduct valuation and confirm financing arrangements.
Step 5: Request HDB Valuation
After obtaining the OTP, submit a request to HDB for the official valuation of the flat. This valuation determines the loan amount and grants you may be eligible for.
If you agree to pay more than the valuation, the Cash Over Valuation (COV) must be paid entirely in cash.
Step 6: Exercise the OTP
To exercise the OTP, you must:
-
Sign the OTP form
-
Pay the remaining deposit (up to $4,000, combined with the option fee)
-
Submit the exercised OTP to HDB within the 21-day period
Step 7: Submit Resale Application
Both buyer and seller must submit their respective portions of the resale application via the HDB portal. This should be done within 7 days of each other’s submission.
HDB will then:
-
Review documents
-
Schedule appointments if needed
-
Issue an approval letter within 2–3 weeks
Step 8: Endorse HDB Documents and Make Payments
Once the application is approved:
-
You’ll be notified to log in and endorse legal documents.
-
Make necessary payments including:
-
Stamp Duty
-
Legal fees (if using HDB solicitor)
-
Balance down payment (if any)
-
You may also apply for CPF usage and disbursement through your CPF account.
Step 9: HDB Completion Appointment
Finally, you’ll attend the completion appointment at HDB Hub or your solicitor’s office:
-
Sign documents
-
Pay remaining purchase price
-
Receive the keys to your new flat
If the seller is still residing in the unit, a temporary extension of stay can be arranged for up to 3 months.
Housing Grants Available
If you’re eligible, these CPF Housing Grants can reduce your upfront costs:
-
Enhanced CPF Housing Grant (EHG) – Up to $80,000 for lower-income families.
-
Family Grant – For first-timer couples buying a resale flat.
-
Proximity Housing Grant (PHG) – Up to $30,000 for living near parents.
These grants are subject to income ceilings and flat lease conditions.
Important Considerations
-
Remaining Lease: Ensure that the flat has at least 20 years left; CPF usage and loans depend on this.
-
Renovation Budget: Older flats may require significant renovations.
-
COV Risks: Be prepared to negotiate or walk away if the seller demands high COV.
-
Legal Advice: Consider engaging your own conveyancing lawyer for peace of mind.
Conclusion
