What are the tax laws for real estate business?

Within a span of 2-3 months, I am about to start a real estate business in Dubai. Thereby I would like to know, for real estate business what are the tax laws or the tax rates for the earning. One of my friends has suggested me to contact any tax advisor in dubai but as I am completely new in this city I have no known person over here. I will be really thankful if anyone helps me by providing the contact details of any tax advisor.

great information
