Kallang Riverside

Note that The Sail @ Maina Bay has the highest capital gain of 202%! That's because when The Sail was launched, Marina was not developed.

 

Just like Kallang Riverside, it may not be developed now, but you can see all the plans that are already done up by the government.

 

Furthermore, Kallang Riverside is FREEHOLD, which means your land will not depreciate!
