Why do service charges catch Dubai property buyers off guard?

Buyers budget the purchase price but forget annual service charges, billed per square foot through the Mollak system (commonly AED 10-30/sq ft, higher for luxury towers with pools, concierge and chillers). On a large apartment that is tens of thousands of dirhams yearly, payable whether occupied or empty. Unpaid charges can block your sale. Check the building's rate first.
