Would you rather buy sale of balance flat for $150,000 and potentially upgrade later or buy $400,000 resale with better location?

Maybe you want to share which is the area of SBF and mature location?

A lot would also depend on the development of the area, which would contribute to the upside of property value. Digital Hub coming up in Punggol would probably add value to the flats there.Serangoon area has limited upside due to the stability of infrastructures.

I think you should consider the sale of balance flat - you can always upgrade later. :)
