I agree with you Uranus. I am saying with 80,000 as an absolute minimum, you can get an older villa, out of town (but still on the island), with old individual A/C units (that will cost a fortune to run). I wouldn't say double though. 110-120,000 and you will get a nice modern villa (not a family home in the Australian sense but a nice villa nonetheless), but you will then need to spend another 20,000 AED a year paying the utilities.
For 65,000 AED a year you can get a nice 3BR apartment in one of the highrise buildings.
