Who decided a property rent area vise in Lahore?

There is a lot of frustration in Rental property segment in especially in Lahore. In the same area even in same street i found two or more different Rents amount for same area property. Even dealers are misguiding the people in Lahore city. Most of time property dealers randomly deciding the rent amount even home owner never knows.
Is there any authority in Lahore city which decide property rent in Lahore area vise?
