5 - 10k in CM will get you a veritable mansion... I lived just outside the city (past tesco lotus) and paid 4000bht for a 3 bed house. In the city you will get a nice apartment for 5 - 6000bht. With it being so easy to drive around the place, my honest advice would be just to get there, rent a bike and drive around for a day. You will see plenty of places to ask at.
