HDB Dipped, Condos Rose: The HDB and Private Housing Decoupling

In the third quarter of 2026, private home prices rose 1.4% quarter on quarter while HDB resale prices eased 0.2%. That is the HDB and private housing decoupling in one line. If you own a flat and are thinking about a condo, the gap between what you sell and what you buy got a little wider again.

The headline numbers

The HDB Resale Price Index moved from 203.6 in the fourth quarter of 2025 to a flash estimate of 202.4 in the third quarter of 2026. The first dip came in 1Q26 at about 0.1%, the first fall since 2Q19. The second was about 0.3% in 2Q26, and the third, released on 1 October, was 0.2%. Over the first nine months of 2026 that adds up to roughly 0.6% lower. This third dip was smaller than the one before it.

On the private side, URA's flash estimate shows the overall index up 1.4%, after 0.5% in the second quarter. Non landed homes rose 0.9%, reversing a 0.1% dip in 2Q. Landed homes rose 2.8%, after 2.5% in 2Q. URA's full statistics are due on 23 October 2026, so the final figures may differ slightly from the flash.

In plain English: the flat you sell is flat to slightly lower, and the condo you may want to buy is still creeping up. Upgraders feel that gap in their cash and CPF.

Why the gap is widening

No single cause explains it. Three things line up, and each is worth understanding on its own.

1. More flats are reaching MOP

The number of HDB flats reaching the 5 year Minimum Occupation Period was 6,973 in 2025. Figures put it at about 13,480 in 2026, up about 93%, and a secondary source puts 2027 at about 18,939. Definitions vary by source, and one estimate puts 2026 higher at 18,425 if 2021 completions are included. Not every MOP flat gets listed, but a bigger pool of eligible sellers gives buyers more choice. Analysts also link the softer prices to supply from BTO and the Sale of Balance Flats exercise. You can see where MOP flats cluster on our MOP town pages.

2. Private homes held up

The landed and non landed numbers above show private demand has not softened the way HDB has. New private sale volume was reported at about 1,082 in 3Q against 2,141 in 2Q (CBRE, as reported in the press), so fewer new units changed hands, yet the price index still rose. That tells you price and volume do not always move together.

3. Rates have turned up from the low

The 3 month compounded SORA was around 1.05% in mid 2026 and had reached about 1.24% by mid October. In October 2026, HSBC and Citi raised their 1.40% condo fixed packages to 1.80% and 1.90% respectively, leaving the lowest condo fixed rate at about 1.70%. The US Federal Reserve raised its target range to 3.75% to 4.00% on 16 September, its first hike since 2023. Higher rates tend to weigh on buyers who depend on a bigger loan, and an upgrader taking a condo loan is exactly that buyer. For more on timing a refinance, see our note on the SORA refinance window.

What it means in dollars (illustrative only)

Take an upgrader with a flat worth S$650,000 who is eyeing a condo at S$1,600,000. The gap at the start of the quarter is S$950,000. Now apply the quarter's index moves.

So in this example the gap widened by about S$23,700 in a single quarter. That is the combined effect of S$1,300 less on the flat and S$22,400 more on the condo. If the same trend continued for another quarter, the gap could widen again, but that is an "if", not a forecast. Index moves can reverse, and your own flat and your target condo will not track an index.

The other side of the story

It would be wrong to read the numbers as a one way story. Here is what cuts against the decoupling headline.

• HDB resale volume rose. 3Q transactions were 7,528 (as of 29 September), up 17.7% on 2Q and up 5.2% year on year. Buyers are active. A market with rising volume is not a stuck market.
• The dips are small. A cumulative 0.6% over nine months is a rounding error on a S$650,000 flat compared with differences between blocks, floors and conditions.
• Many million dollar flats still transact. 597 HDB flats sold above S$1 million in 3Q26, about 8.5% of transactions. We looked at that split in why the RPI fell as million dollar flats hit a record.
• Not every MOP flat is listed. Many owners stay put, so the supply figure overstates what buyers will actually see.
• One quarter is not a trend. The private index and the HDB index are both flash estimates here, and URA will update on 23 October.

Who this matters for

It matters most if you are an HDB owner past or close to MOP who is thinking about a condo within the next year or two. For that group, the question is less "will HDB fall" and more "how much room is there between my sale proceeds and my target purchase, and how does my loan hold up at today's rates?"

If that is you, two guides are worth reading first. Sell HDB first, buy condo second walks through that order, and sell first or buy first compares the two sequences. For the affordability side, see HDB to condo upgrade affordability.

It may not suit everyone. If the gap between your flat and your target condo is already stretching your budget, or you are happy where you are, a widening gap is a reason to pause, not to rush. Our piece on when not to upgrade covers that case honestly.

A checklist to review with your agent and banker

General information only. These are questions to bring to a conversation, not answers.

• Current flat value: recent transactions for your block or nearby blocks, same flat type and similar floor level, not the island wide index.
• CPF refund: how much CPF used on the flat, plus accrued interest, goes back to your accounts on sale.
• Loan eligibility at today's rates: your bank's assessment of income and commitments at current rates, not the rate you had two years ago.
• ABSD timing: whether owning two properties at once triggers additional buyer's stamp duty, and how the sequence of sale and purchase affects that.
• Overlap window: where you will live and how you will fund the months between selling and completing.
