Is it better to buy Dubai property in cash or with a mortgage?

Cash means no interest, lower fees, a faster deal and stronger negotiating power - but ties up capital. A mortgage preserves liquidity and can work as positive leverage when Dubai's gross rental yields (often ~6-8%, verify) exceed a ~4-5% mortgage rate, though you pay interest and financing costs. The right choice depends on your liquidity and goals; this isn't investment advice.
