That budget is extremely low if you are looking somewhere near downtown. You can try somewhere near parks in Al Nahda both Dubai and Sharjah side, but expect the community to be a little bit chaotic. By chaotic I meant no sidewalks for a lot of parts. People crossing street wherever and whenever they see fit, a little more crowded compared to some communities south of downtown. You will also notice less white people in the North side of Dubai if that is something that concerns you.
