Where to Find Singapore’s Oldest HDB Flats (And What They Cost In 2025)

As an aside, some of the oldest 3-room flats are the ones built in Tiong Bahru by SIT (the predecessor to HDB). These flats can be much larger, with two toilets, a balcony, and a more generous service yard, but they rarely pop up on the market. 

Also note that some of the SIT-era landed projects, which are still HDB projects and very old, are described as being 3-room. We would consider these to be special exceptions, and listings are very rare. 

4-room flats

Many of these were found in Bedok, Kallang/Whampoa, and Toa Payoh, as seen from the consistent resale activity for flats built before 1975. These towns still show regular transactions involving 50-year-old units, unlike newer estates, where none exist 

We would expect a premium for the more famous areas like Marine Parade or Bukit Timah; at least partly because the alternatives there (e.g., condos) are so much pricier. If you really want to live in those areas, the ageing resale flats may be as low as it gets 

5-room flats

Again, we see the largest number of transactions in Bedok, Kallang/Whampoa, and Toa Payoh. 

Despite their age, the prices are still high: even in well-connected central areas like Kallang/Whampoa and Toa Payoh, some of these 50-year-old flats are barely staying under $800,000 on average. We probably don’t need to tell you that the most desirable ones, like DBSS flats at Dawson or at Pinnacle @ Duxton, are famous for breaching the million-dollar mark. 

The main takeaway 

If you’re hunting for an old but central home, your search will likely lead you to Bedok, Kallang/Whampoa, or Toa Payoh; these veteran HDB towns that still see active transactions for older flats, suggesting interested sellers. 

For famous enclaves like Marine Parade, transaction data suggests that listings in these areas will be infrequent, so we wouldn’t count on finding what you want. 

From the above, you can expect to spend roughly:

• Around $400,000 for a 3-room
• $500,000 to $600,000 for a 4-room
• $750,000 – $850,000for a 5-room

These flats may not have much runway left on their leases, but they offer something that most of us couldn’t otherwise afford: size and mature surroundings, at prices below $1 million. And given that we’ve only just heard about the end of SERS, there’s a real likelihood the prices could dip even more if you can wait longer. 

Just be sure that it’s the end point of your property journey, as it’s very possible that you’ll incur a loss if you try to sell them another decade down the road.
