Blk 509B Yishun Ave 4 flats for sale, against recent transactions
No flat here is asking below recent resales of similar-sized flats in this block. We could compare one flat on sale.
We compare each flat on sale with recent sales of similar-sized flats in the same block. A size only counts if there have been at least five sales of it. We don’t compare floors, so a flat lower down can look cheaper than it is.
