Be very careful on the rental returns as many calculate current rental rates and do this before deducting the community and maintenance fees for the unit. Many developers are not telling the buyers about the community fees and only mention maintenance fees to the buyers. Some community fees along with the maintenance fees are around 40-50K per year around the Burj Area So if they tell you that you can expect 150K per year in rental then be sure to see if this rental return is before or after you pay the community fees along with the maintenance fees. When hey hand you the unit they make you pay the maintenance fees up front too

Dubai may be tax free but these community fees and maintenance fees can be worse then taxes. In California Property Taxes are about 1.8% (take or give) which is not cheap and if you are looking at something near the Burj you can basically nearly double to triple that from the community and maintenance fees
