There are a number of steps/regulations on buying in Dubai, and if you are resident here, the amount of time you have been working in Dubai, and your salary will affect your eligibility to obtain a mortgage. Most banks will now finance from 70-90% of a property. Typically, you should be resident no less than 1 year, and provide 6 months bank statements.

HSBC is, in my experience, one of the more flexible banks - they will offer you 60 times your monthly salary, up to a value of DHS. 5 million.

Hope this helps - I can put you in touch with some good, reputable agents who deal with buying homes if you wish!?
