What to Check When Buying a Resale HDB Flat Before You Submit the Offer

Submitting an offer on a resale HDB flat is not the first step. It is the culmination of a series of verifications that should happen before the offer is made.

Here is what to check.

1. Confirm Your Eligibility

Before you make an offer, confirm that you are eligible to buy the flat you are looking at.

Key eligibility factors:

• Citizenship: At least one buyer must be a Singapore Citizen or PR (with a Citizen family member) to buy a resale HDB flat. PRs can buy together but have limited flat types available.
• Ethnic Quota: Every HDB block has an Ethnic Integration Policy (EIP) quota. If the Chinese, Malay, or Indian quota for the block has been reached, a buyer of that ethnicity cannot purchase there. Check the EIP quota online through the HDB website before committing.
• Ownership status: You cannot own another HDB flat or private residential property when buying (subject to specific rules). Private property owners must dispose of the private property within six months of buying the HDB resale flat.
• Income ceiling: For certain grants and flat types, income ceilings apply. Confirm your household income position before factoring in grant amounts.

2. Check the Remaining Lease

The remaining lease affects CPF usage, loan tenure, and future resale potential.

If the remaining lease does not cover the youngest buyer to age 95, CPF usage is pro-rated. If the remaining lease is below 60 years, buyer financing becomes progressively restricted.

Know the exact year the flat was built and calculate the remaining lease. The HDB website shows the lease commencement date for every block.

3. Get an Independent Valuation Before Negotiating

HDB valuations are not automatically provided when you express interest in a flat. A valuation can be commissioned through HDB's panel of valuers.

The valuation is important for two reasons: it sets the baseline for CPF usage (CPF can only be used up to the lower of valuation or purchase price), and it determines whether COV (Cash Over Valuation) is being paid. COV must be paid in cash, not CPF or loan.

If the seller wants $680,000 for a flat valued at $650,000, you are paying $30,000 COV in cash on top of your standard downpayment. Know this before you negotiate.

4. Assess Your Financing Position

Confirm your loan eligibility before you make an offer. This means:

• Calculating your TDSR (maximum 55% of gross monthly income across all debt obligations)
• Determining whether you are using an HDB loan or bank loan (HDB loan requires an HDB Loan Eligibility Letter; bank loan requires an in-principle approval)
• Understanding how much CPF you have available after factoring in any existing property
• Calculating your minimum cash downpayment (HDB loan: 20% if no prior outstanding loan; bank loan: minimum 5% cash, 20% total downpayment)

5. Inspect the Flat Condition

A resale flat is sold in its current condition. What you see is what you get.

Check for: water stains or seepage from the ceiling or walls, signs of dampness in bathrooms, the condition of the electrical wiring (older flats may have outdated systems), the condition of windows and grilles (replacement can be costly), and the general state of the kitchen and bathrooms.

If renovation is needed, get a rough estimate before you finalise the price you are willing to pay. Renovation costs for a complete overhaul of a 4-room flat typically range from $40,000 to $80,000 or more.

6. Check the History of the Flat

HDB's website allows you to check the transaction history of the block and nearby flats. Check what similar units in the block have transacted for in the last 12 months. This tells you whether the asking price is in line with recent comparable sales.

Also check whether there are any upgrading programmes planned or completed for the estate. Neighbourhood Renewal Programme or Lift Upgrading Programme works can add value but may also involve construction noise and inconvenience.

Frequently Asked Questions

What is the Ethnic Integration Policy (EIP) quota and how does it affect buying an HDB resale flat?

The EIP ensures that Singapore's HDB estates maintain racial integration. Each block has a maximum percentage of flats that can be owned by each ethnic group. If the quota for your ethnicity has been reached in a specific block, you cannot purchase a flat there even if you are otherwise eligible. Check the current EIP quota on the HDB website before making an offer.

Can I buy a resale HDB flat if I currently own a private property?

Yes, but you must dispose of the private property within six months of buying the HDB resale flat. You cannot retain both simultaneously. The six-month disposal period is monitored by HDB.

What is COV and how much should I be willing to pay?

COV (Cash Over Valuation) is the amount paid above the official HDB valuation. It must be paid in cash, not CPF or loan. Whether to pay COV and how much depends on how competitive the location is, how urgently you need the flat, and what comparable flats in the area are transacting at. There is no fixed rule, but know that COV is an additional upfront cash cost beyond your standard downpayment.

How long does it take to complete a resale HDB flat purchase?

From OTP signing to key collection, the standard HDB resale process takes approximately 8 to 12 weeks. This includes HDB processing time, CPF utilisation approval, and loan processing. The timeline can be extended if documents are incomplete or if either party has complications.

What happens after I get a valuation for an HDB flat?

The valuation is used to determine your CPF usage limit and to assess COV. Once you have the valuation and have agreed on a price with the seller, the seller grants you an Option to Purchase (OTP). You have 21 calendar days to exercise the OTP and proceed with the transaction. The OTP fee is typically $1 for most resale flats and is negotiated between buyer and seller.
