Pros
- you buy at below market price, that's all

Cons
- you don't know the house condition, damages
- owner might won't move out
- owner might holding a grudge against you (happened to me)

The house is empty, I move in after acquire the grant, but the owner came and start creating scene, spit and throw rubbish, we go lepak mamak, belanja him makan, turn out he in deep financial situation, I gave him rm500 and I didn't see him around anymore. That is a few years ago and now house got cctv.
