Recently I was looking for a rented house. So based on that you atleast need a 6000QR for a decent 2 bedroom unit. If you need gym, swimming pool etc you atleast need 8500QR for a big 2 bed room unit. Again it also depends on your location, the same 2 bedroom unit can cost you about 12 to 18000if you are looking on the porsch areas of Qatar. But for 2500 you can get a studio only and most llikely that will be a partitioned unit of a villa. Cheers.
