How accurate is this estimate for Alpha Apartments?
Too few sales since Q4 2025 to score the estimate here. Three are the minimum, and this project has not had them.
What the rent says
What this home earns against what it costs, set beside what homes like it earn.
2.26% gross yield
S$76,800 of rent a year against the estimate above · 0.89 points below flats like it
Leases signed here within a quarter of this size run about S$6,400 a month, the middle of 1 of them.
In the rest of the central region, freehold flats yield 3.15%, from 864 projects. Too few share this home's remaining lease to measure that separately.
A yield above the mark means the flat rents well for what it costs, which can point to a keen rental patch or a price the sales alone have not caught up with. Below it, buyers are paying for something a tenant will not, such as the address itself.
