How much are the total costs of buying a property in Dubai?

Budget roughly 6-8% of the purchase price on top of the price itself. A cash resale runs about 6-7% (4% DLD fee, ~2% agency commission plus VAT, and a few thousand dirhams in trustee, title-deed and NOC fees). Add a mortgage and it rises to about 7-8% once bank and registration charges are included.
