PA laws for raising rent?

[Zane Britton]

I currently have a property(duplex) in central Pa under contract and the rents are a good amount below the average for that market. Are there any laws in Pa that say you need to give a certain times notice before raising rent? I plan on raising the rent 10-15%($55-$85) per unit and I was going to give them a 60 day notice prior to doing that. Thanks In advance!

Yeah, I think you just have to honor existing leases
