Frequently Asked Questions About Condo to HDB Downgrading

Do I still need to wait 15 months before buying a resale HDB flat after selling my condo?

No. As of July 28, 2026, the 15-month wait-out period is removed for private property owners purchasing a non-subsidised HDB resale flat with a bank loan. However, a 30-month wait-out applies for subsidised purchases or HDB loans.

Can I use my CPF to buy a resale HDB flat after selling my condo?

Yes, but you must first refund all CPF monies used for your condo purchase - plus accrued interest - back to your CPF Ordinary Account. You can then use your CPF funds for the HDB purchase, subject to remaining lease requirements and retirement sum obligations.

What is the resale levy and do I need to pay it?

The resale levy applies if you previously purchased a subsidised HDB flat and are now buying a second subsidised flat. Resale levies range from S$15,000 to S$55,000 for HDB flats. If your condo was your first private property and you did not previously own a subsidised HDB flat, the levy may not apply - but verify with HDB. This can also matter if a resale flat bought earlier had any subsidy history, so it is worth checking your past flat purchase record with HDB.

How much should I budget for renovation of a resale HDB flat?

For a standard full renovation, expect S$45,000–S$75,000 for a 3-room flat, S$55,000–S$85,000 for a 4-room flat, and S$70,000–S$120,000 for a 5-room flat. Costs depend on flat age, scope of work, and material choices.

Can I buy a resale HDB flat before selling my condo?

Yes, but you must dispose of your private property within six months after completing the HDB resale flat purchase. You may also face Additional Buyer's Stamp Duty if you own both properties at the same time, and condominium buyers are charged based on their residency status. If you sell very early, Seller's Stamp Duty can reach 16% if the condo is sold within the first year of ownership. If your sale and purchase timelines do not line up, you may need temporary housing solutions such as short-term rentals, staying with family, or negotiated extensions.

Are there any grants available for former condo owners buying resale HDB flats?

Most housing grants - including the Enhanced CPF Housing Grant and Proximity Housing Grant - have income ceiling and property ownership requirements, and HDB loan options can also depend on the resale market and current policy conditions, so former condo owners should verify the latest rules before committing. Former private property owners may not qualify for these grants, and treatment can differ when buying HDB resale flats, but check the latest eligibility criteria on HDB's website as policies can change.
