Most expatriates in Dubai live in rented accommodation. This is perfectly normal, if you plan to work in the emirate for a couple of years and then leave. Still, those who plan to stay for longer should definitely consider buying a property. The investment can keep paying off even after you leave. In addition, given the slump in the Dubai real estate market from a year back, you can readily find an affordably priced property. Getting a home mortgage will also not be a problem, as long as you know what to expect as a borrower.
