What is the cost of living like in Dubai. And what salary would be reasonable to move there?

By Enthe cost of living in dubai is a bit dearer than living in sharjah, alain except abu dhabi.

the rent in bur dubai one bedroom apartment will be around 1500 dhs. mostly the utiltiy bills (water, electricity) are included in the rent, so don't have to worry about bills. there would be spacious kitcken, washroom. some of these apartments also have a garage and a carpark too.

if u have a good job earning 4500 dhs or over it is ideal for you to move to places like karama, jumeirah, etc. dubai is a good place to live in provided u have a decent salary to fund from.

Well Dubai is quite expensive. Salary starting from 3000USD/month is ok to rent appartment, to have a car loan and to get food whatever you like..
depends on u and ur education.
