+1 that hdb and old condo is much more spacious and better for HT hehe. Old condo some are freehold or 999 yo, can consider.
Bro jag, being a fellow parent w young kids, my suggestion is get a 4 bedroom unit with good layout as msg-ed. Won’t regret.
More space for whole family. The extra room makes a day n night difference. It can be used for kids own room (1 kid 1 rm) , future family expansion, grandparents stayover when they care for your child, or helpers room.
Or in future, best still, u can have 1 rm for ht now, and got potential to combine 2 rms into a bigger ht room later on. Or vice versa.
So much flexibility to play with.
Typically, hdb w 4 bedrooms are easy to sell too as they are rare. Most are considered 5-room flat so u pay the same maintenance fees as 5rm flat.
