HDB transaction activity in 2026 has so far remained concentrated in the more common flat types, particularly 3-room, 4-room and 5-room units. Across both sale and rental transactions, 4-room flats consistently recorded the highest volumes among the main HDB unit types, while activity generally increased from Q1 to Q2.
Figures for 1 July to 27 Aug 2026 so far shows a similar pattern, with 4-room flats continuing to lead transaction activity, followed by 3-room and 5-room units.
HDB Sale Transactions

Sale transactions increased across all unit types from Q1 to Q2.
Among the main flat types, 4-room flats remained the most actively transacted, rising from 2,603 transactions in Q1 to 3,073 in Q2. 5-room flats also saw a noticeable increase, from 1,374 to 1,666 transactions, while 3-room flats rose more moderately from 1,480 to 1,587.
This shows that most sale activity continued to be concentrated in the 3-room, 4-room and 5-room segments, with 4-room flats leading by a clear margin.
Although 1 July to 27 Aug 2026 volumes are currently lower than Q2, this is expected as the quarter has not ended.
So far, 4-room flats have recorded 1,704 sale transactions, while 5-room and 3-room flats have reached 896 and 870 transactions respectively.
The rankings remain largely unchanged, suggesting that buyer activity is still concentrated in the same mainstream flat types.
HDB Rental Transactions

The rental market shows a very similar pattern from Q1 to Q2.
4-room flats recorded the highest rental volume among the main flat types, increasing from 5,102 transactions in Q1 to 5,647 in Q2. 3-room rentals rose from 3,034 to 3,259, while 5-room rentals increased from 2,991 to 3,231.
While rental volumes generally increased from Q1 to Q2, the changes were less pronounced than in the sale market. For example, 2-room rental transactions were almost unchanged at 302 in Q1 and 304 in Q2, while Executive flats increased slightly from 676 to 706.
This points to a relatively stable rental market, with demand continuing to be concentrated in the same unit types.
What Stands Out From the Data?
The clearest trend is the continued dominance of 4-room flats. They recorded the highest transaction volumes among the main flat types in both the sale and rental markets across Q1, Q2 and from 1 July to 27 Aug 2026.
3-room and 5-room flats also remained consistently active, showing that most HDB transaction activity is centred around the unit types commonly used by families and larger households.
Another key trend is that Q2 was stronger than Q1. Transaction volumes increased across almost every category, particularly in the sale market. At the same time, the current numbers for 1 July to 27 Aug 2026 should be viewed as an early indication of Q3 rather than a full-quarter comparison.
One notable takeaway is the difference in scale between the sale and rental markets. Rental volumes are substantially higher across most unit types, especially for 3-room to 5-room flats, while Executive and Multi-Generation units remain relatively niche, although this could be attributed to the smaller number of Executive/Multi-Gen units available compared to the rest.
Despite changes in overall transaction volume between quarters, the mix of activity has stayed broadly consistent, suggesting there has not yet been a major shift in demand towards either smaller or larger HDB unit types in 2026.
