According to EdgeProp, the breakeven cost is $1,837 psf.
After factor in a 15% profit margin, the estimated selling price will be around $2,113 psf.
This is about the same price as the recent transaction (highest record $2,189psf) at Uptown @ Farrer which is a newly TOP project beside Farrer Park MRT station.
In addition, this price tag is around $200-300 psf higher than the last new launch project nearby, Sturdee Residences and it was completed 3 years ago.
Piccadilly Grand is a bigger and newer project in the vicinity as compared to the other two.
In my opinion, in such a decent project in a central location of Singapore, I would recommend you to buy if the price fall below $2,300psf.
