it's a tough question to be honest, one that I am not able to answer.
Really depends on your standard of living! If your wife is gonna be working, then perhaps thats not bad as she could suppliment ya income.
Water and electricity are your biggest costs per month, other than your rent. Going out, clothes, food is pretty reasonably priced.
I take it you have no kids, if yes, then you will need to double that salary or else make sure they pay for education.
8500 per month is what, US$1200 per month, not a lot to be honest.
dhs. 15-20,000 per month would be better, but as i said, it all depends on how you wanna live. check out
www.gulf-news.com go into the classifieds and see how much places are for rent.
You may get by on 8500 per month, but for two people you may be stretched, also, you wil need to get the housing increased. Oh, by the way, it's gonna cost you around dhs.10-20,000 just to furnish the place.
