Is it worth upgrading from HDB to condo in 2026?
It can be, but only if the four tests below pass on your own figures, because the extra cost is large and the benefit is mostly lifestyle, tenure and exit flexibility rather than a sure financial gain. This page sets out the numbers and does not tell you what to do. A condo gives you private facilities, a freehold option and a wider buyer pool; an HDB flat gives you lower running costs and an HDB loan option.
What does it cost to upgrade beyond the price?
In the site's illustrative sell then buy case, upgrading adds about S$143,000 on top of the condo price, with renovation the largest line. Substitute your own figures, because every line varies.
| Cost item | Illustrative amount | Basis |
|---|---|---|
| HDB agent commission plus GST | ~S$14,170 | 2% of S$650,000, plus 9% GST on the commission |
| Legal fees, HDB sale | ~S$2,000 | Illustrative. Confirm with your lawyer or HDB |
| Buyer's Stamp Duty, S$1.4m condo | S$40,600 | IRAS schedule |
| ABSD, sell then buy path | S$0 | 0% for a Singapore Citizen buying a sole property |
| Legal fees, condo purchase | ~S$2,800 | Illustrative. Confirm with your lawyer |
| Bank and valuation fees | ~S$700 | Some banks waive this |
| Renovation | ~S$70,000 | S$50 to S$90 per square foot on about 1,000 square feet |
| Interim housing | ~S$12,000 | 4 months at about S$3,000 a month |
| Moving | ~S$1,000 | Packing and movers |
| Illustrative total | ~S$143,000 | Excludes the condo price and loan |
If you must buy before you sell, add 20% ABSD upfront, S$280,000 on a S$1.4m condo, refundable only if the HDB flat is sold inside IRAS's 6 month window. See sell first or buy first and the full cost breakdown.
How do an HDB flat and a condo differ in running costs and loans?
A condo costs more every month to run and is financed by a bank loan only, while an HDB flat has lower running costs and an HDB concessionary loan option. The table compares them using figures already published on the site.
| Dimension | HDB flat | Private condo |
|---|---|---|
| Loan options | HDB concessionary loan at 2.6% p.a. (HDB, as of 2026), or a bank loan | Bank loan only. Typical bank rate about 1.5% p.a. (Winfred Quek market survey, as of 2026), floating with the market |
| Loan limits | MSR 30% of gross income for HDB loans and bank loans on HDB flats; LTV 75% for a first housing loan | TDSR 55% of gross income across all debts; LTV 75% first loan, 45% for a second while a first is outstanding |
| Monthly upkeep | Service and conservancy charges about S$50 to S$100 a month | MCST maintenance fees about S$200 to S$800 or more a month, depending on facilities and unit size |
| Annual property tax, owner occupied | Most HDB owners pay about S$0 to S$500 a year | About S$1,000 to S$5,000 or more a year. First S$12,000 of Annual Value is taxed at 0% |
| Lease | 99 years from the first lease. No freehold HDB exists | Freehold or 99 year leasehold. Freehold typically commands a 15 to 25% premium (market estimate, not an official figure) |
| Selling flexibility | Minimum Occupation Period first; Ethnic Integration Policy quotas apply | No occupation period; Seller's Stamp Duty applies within the holding period; open to foreign buyers |
| Facilities | Void deck and town amenities | Private pool, gym, security |
Does the order of selling and buying change the answer?
Yes, more than any other single factor. If you sell the HDB flat first, a Singapore Citizen pays 0% ABSD on the condo, but you need somewhere to live in the gap. If you buy first, 20% ABSD is payable upfront and refunded only if conditions are met. The comparison is in should I sell first or buy first.
Should I consider an Executive Condominium instead?
An EC is worth testing if your household income is within the ceiling, because ECs typically transact 20 to 30% below a comparable private condo at launch (Winfred Quek analysis of new launch transaction data, as of 2026). The household income ceiling is S$16,000 a month on sale now, and S$18,000 for new units on EC sites tendered from 24 August 2026 (HDB). An EC carries a Minimum Occupation Period before it opens to all buyers. See EC vs condo and HDB to EC vs HDB to condo.
How do I test whether the upgrade is worth it for me?
Run four tests with your own numbers before you commit. First, net proceeds: sale price less loan, less CPF refund with 2.5% accrued interest, less commission and legal fees, which is your actual cash (see can I afford to upgrade). Second, loan: whether your income supports the new loan under TDSR 55%. Third, the gap: months of rent or family stay between handover and move in. Fourth, the carrying cost: monthly maintenance and tax against your cash flow, see the real cashflow check. Winfred runs this on your numbers in a Property Portfolio Analysis, and the upgrade cashflow tool gives a first estimate.
Frequently asked questions
How much does it cost to upgrade from an HDB flat to a condo?
In the site's illustrative case, a S$650,000 HDB sale and a S$1.4m condo purchase add about S$143,000 of costs on top of the price, including S$40,600 Buyer's Stamp Duty and about S$70,000 renovation. Your figures will differ.
Do I pay ABSD when I upgrade from HDB to condo?
Not if you sell the HDB flat first as a Singapore Citizen, because the condo is then your only property. If you buy first, 20% ABSD is payable upfront and is refunded only if IRAS's conditions are met.
Is a condo cheaper to run than an HDB flat?
No. Condo maintenance fees are about S$200 to S$800 or more a month against about S$50 to S$100 a month in HDB service and conservancy charges, and condo property tax is typically higher.
What happens to my CPF when I sell my HDB flat to upgrade?
CPF used for the flat is refunded to your CPF account with accrued interest at 2.5% per annum. That money stays in your CPF Ordinary Account and can be used towards the condo, subject to CPF rules.
Is an Executive Condominium a cheaper way to upgrade?
An EC typically transacts 20 to 30% below a comparable private condo at launch, but it has a household income ceiling and a Minimum Occupation Period. Check your eligibility with HDB.
What are the three key takeaways?
- Upgrading adds large costs on top of the price: about S$143,000 in the site's illustrative case, and renovation is the biggest line.
- Selling the HDB flat first means 0% ABSD on the condo for a Singapore Citizen, while buying first needs 20% ABSD upfront and a refund that depends on IRAS's 6 month window.
- Run four tests on your own numbers before deciding: net cash and CPF, loan under TDSR 55%, the housing gap, and the monthly carrying cost.
