How much more does a condo cost than a 4-room HDB flat?
From $735,000 in Yishun to $1.66 million in Bishan, here's what it takes to move from a 4-room flat to a 3-bedroom condo in the same town.

A 4-room flat sells for about $550,000 in Woodlands and just over $1 million in Queenstown. Yet in neither town does that cover even half the price of a nearby 3-bedroom condo.
We compared a year of recorded sales across 20 towns to find out how big the upgrade gap really is, and how much more you might need to pay.
The gap between your flat and a condo
Where you live makes a difference to how much you could get from selling your flat. But even in towns where resale prices are higher, moving to a private condo can mean a substantial jump in price.
To understand the difference, we compared recorded resale transactions for 4-room HDB flats with recorded sales of nearby 3-bedroom private condos over the same 12-month period.
Rather than comparing the cheapest flat with the most expensive condo, we looked at typical sale prices in each area. This gives a more useful starting point for homeowners considering an upgrade.

Typical = median resale price, September 2025 to August 2026. Condos are 3-bedroom units of 900 to 1,300 sq ft in the same URA planning area as the HDB town; bedroom counts come from URA rental records. Six towns with too few sales are left out. Download the data.
The difference is the upgrade gap: how much more the condo costs than the flat, before accounting for the costs of selling and buying.
Why the gap matters
Suppose your 4-room flat sells for $700,000 and the condo you want costs $1.4 million.
The difference is $700,000. But that does not automatically mean you need to come up with another $700,000 in cash.
What matters is how much money you have left from selling your flat, after settling your outstanding housing loan and accounting for the CPF savings that must be refunded to your CPF account, including accrued interest where applicable.
You will also need to budget for the costs of buying the condo, including Buyer’s Stamp Duty, legal fees and any Additional Buyer’s Stamp Duty (ABSD) that applies. Your loan eligibility and the amount of cash you must pay will also affect how much you need to fund the purchase.
In other words, the difference between two property prices is only the beginning of the calculation.
What does this mean for your upgrade?
The town-level comparison helps you understand the broad price difference. But your own situation could look quite different.
A homeowner who bought their flat many years ago may have a different outstanding loan and amount of equity from someone who bought more recently. The condo they choose also matters: even within the same area, prices can vary considerably between developments and units.
This is why it helps to work backwards from the home you want to buy.
Take Treasure at Tampines, Riverfront Residences or Parc Esta, for example. Instead of asking only whether a condo is more expensive than your flat, ask three questions:
- How much could you realistically sell your flat for?
- After settling your loan and accounting for CPF refunds, how much would be available for your next purchase?
- After including buying costs and financing, can you afford the condo you have in mind?
These are the questions that turn a broad price comparison into a decision you can act on.
Reva's sell-and-buy check is designed to help you work through that calculation using your current home and the property you are considering.
Before you make the move
Upgrading from an HDB flat to a condo is not simply a matter of finding a property that costs more than your flat. The real question is whether the sale of your current home, your available funds and your borrowing capacity can support the next purchase.
The price gap across Singapore's towns gives you a useful starting point. Your own numbers tell you whether the move is realistic.
Before shortlisting condos, work out what your flat could contribute and how much more you would need to fund the upgrade.
