Abu Dhabi has an official rent index, and it's easy to check for free. It's part of a tool called the ADREC Interactive Map, run by the Abu Dhabi Real Estate Centre. The map shows the average rent for any area, based on real signed rental contracts, not just online listings. Checking it takes about five minutes, and anyone can use it.
