Ok, I will try and give you a rought guide, it may be a little bit expensive but I do not believe in living in squalour.
Studio Apartment: circa dhs.40-45,000 per year (will include pool, gym, security and undercover parking
1 Bedroom Apartment: circa dhs.50-55,000 per year (ditto)
2 bedroom Apartment: circa dhs.60-65,000 per year (ditto)
None of these will be furnished although there might be one or two kitchen appliances incl.
As above but maybe 10-15% cheaper.
Serviced Apartments (Studios) are not a bad way to start off if you have nowhere to stay, but could set you back dhs.5-6,500 per month.
If I was you, i would try and find someone to share with. if you can do that, then the best thing to do would be to rent a Villa. 3 bed villas can be rented for around 60-65,000 per year.
Prices in Dubai for rented accommodation is going up monthly.
Going to live in Sharja is cheaper, but one hell of a traffic jam to get into Dubai.
To furnish your apartment you will need circa dhs25-30,000 (thats everything, except those womanly touches)
Hope this has helped, and if you find something cheaper, please let me know!
Disclosure: I do not work in the Renting business nor do i work for a letting Agent. I have been looking for 3 months!
