Talked to my attorney on this one and he said no need to draft up new lease or a lease amendment... just send them a letter saying who to send new payments too and change the lease out when the lease is up.  

I should amend my comment.

The act of April 6, 1951 (P.L.69, No.20), known as The Landlord and Tenant Act of 1951, is amended by adding a section to read:Section 505.1.

We came to an agreement that we would amend the lease and use her security deposit to cover May's rent, if she agreed to leave 6 June (lease was through Oct). 

You need to see what zone, A, AE, V, X...I actually had a property removed from the floodplain via a LOMA - Letter of map amendment.

Put everything on the proper paperwork (PA amendment or whatever your Realtor suggests) and make sure the lender is in the loop (have them review language, etc). 

Yeah he seems nice , amend the lease ..

When they gave us copies of the leases, all he did was change the ending lease date to 2019 but signatures are from 2016 and they don’t have a lease amendment and seller and tenant didn’t initial the change on the lease.I’ve requested and supplied an estoppel form to be fully filled out and signed by tenant and owner and for the leases to be initialed properly for the recent changes.Selling agent says he can’t make tenants fill out estoppel and owner isn’t making much effort to get it filled out either.

So much for that 4th amendment...The Fourth Amendment of the U.S.

Finally it is important to remember that your tenant does not have to agree to the increase so make sure when you sign the contract (which requires a 1 year lease) that there is an amendment in place that if the tenant will not agree, or if the increase is denied, that the lease reverts back to a month to month lease.
