Hi I live in Philadelphia PA. I have a lease for 1 year on $710/mo rent witch I signed with previous owner. (This is a condo appartment). Lease will end on 2/28/2008. This month my new landlord changed air conditioning-heating unit (this is heated and air conditioner in 1 unit). He wants to increase my rent by $50. Can he increase my rent during 1 year lease agreement?
If he can, under what sircumstances he can do it?
