I think location is the main concern. U can see the house over 40yrs old in the peak still worth over $10000/sq.ft so don't worry about the age of the house. LOCATION is the main concern. Of course, u need to put a lot of money to change all those wire n pipe but it is worth. Even my friends live in new building but after 4/5 yrs also have water pipe problems, so if u change all b4 u move in,that shouldn't be a problem. School net is also a good point too. That's why I am living in 28yrs old building but new renovated already. Everything is fine.
