Abu Dhabi rent cap for 2010 remains at 5% according to a WAM report 16 November 2009, and maximum tenancy contract length increased from 4 to 5 years. Oddly, The National in Abu Dhabi says that the Dubai rent cap is also 5%, which conflicts with RERA Dubai information that a variable rent cap applies - from 0% to 20% depending on current market rates in the same area.
