Well - Ofcourse you can find things in lower price as well but since he mentioned his budget was 9-10 K so I told him he should be prepared to give this rent for a 3 bed room apartment as he got 4 kids.
So if he would want to live in a decent area, thats how he will be paying and he should be prepared.
Other than providing him some information, I did not have any intentions at all :)
