Dun hesitate, just wack lah. I hv made my first million out of this property boom since 2008, and is on my way to make the 2nd million.
Singaporeans in general are few hundred Ks richer bec of this boom, and you just have to realise that paper gain and reinvest the money in other newer properties. Anything new always sell faster and higher than old ones.
Either you take the risk now and push yourself to another level or continue to slog and remain where you are. The world will not wait for you, so do the housing prices.
