Raising Rent in PA

[Joe Kulbacki]

I know I knew this at one point, but I'd like to get some expert answers. In PA, when raising rent, how many days notice do I need to give the tenant? Also, if the tenant is on a month to month, what is the process to raise their rent? The previous owner just wrote the date and new amount on the old lease. Finally, when moving a tenant from a year to year lease to a month to month, how many days notice needs to be given. The previous owner had a year to year clause at the end of each year.

Thanks in advance!
