Rental & Yield

What this block rents for, and the gross rental yield (annual rent ÷ resale price). This block has too few rentals on record, so figures shown are the Yishun average.

Flat type Median rent /mo Gross yield Based on
3-Room $2,650 typically $2,500–$2,800 7.3% Yishun avg · block too thin
4-Room $3,100 typically $2,900–$3,300 6.6% Yishun avg · block too thin
Gross yield is annual rent before maintenance, property tax, and vacancy, so net return is lower. Renting out a whole HDB flat requires meeting the 5-year Minimum Occupation Period and HDB approval. Rents are owner-declared to HDB and unverified.
