Tenant Turnover Situation

[Angela Armstrong]

Hello, I’m sure I do not have a unique situation but it is the first time for me. I had a tenant give the proper 30 day notice that they will be terminating the lease because they will be purchasing a home. I’m the meantime I was able to find a new tenant who has paid the security deposit, first month rent, and has scheduled utilities to be transferred to their name but no lease has been signed yet. A week before the original tenants official move out date was scheduled they informed me that they were “dropped” by the lender and they are starting to work with a new lender. I had 14 days to turn over the property and now they don’t even know when they will be out. My question is how should I proceed and who am I legally obligated to, the old tenant or the new tenant?

I am in Pennsylvania.
