Tenant wants to break lease. How would you proceed?

[Tyler Speelman]

Closing on a property in Ohio in 4 days. Current friend and future tenant has informed me they are moving. The lease with current landlord says 2 months notice must be given before moving. Their current lease expires in 02/19. 

Future tenant states:  "she has had a handshake agreement with current landlord and they let them move out pretty much whenever."

Trying to think win-win to preserve friendship and also benefit rental business. 

How would you proceed?
