Dhs 180k is not quite enough for a decent villa, a maate just got a 3 bed in Sas Al Nakeel for 190k and you should be able to get 3-4 bed in Raha Gardens for 200-240k. Prices are all very neg at the moment so you may be lucky at 180......
Managed to get 30% reduction for my villa renewal from the landlord(thief) for 2009/2010.
