Tan noted that the Sales for Affinity at Serangoon was well-spread over one-bedders to four-bedders-plus-study apartments with three out of ten strata houses sold at an average of $2.33m. He said, “Prices for both projects set a new benchmark for the location with Affinity at Serangoon achieving an average selling price of $1,550 psf whilst Garden Residences units were sold at a tad higher at $1,660psf.”

Based on selling prices, if sustained, these translate into a margin of 14% (The Garden Residences) and 19% (Affinity at Serangoon) respectively.
