Get in writing and not just a verbal confirmation. Last thing you want is a SURPRISE!!!

Good agent/broker will know what to do:

you can buy now and lease back on month to month with firm "exit" date. Some state will allow you to lease back for thirty days without creating a tenant-landlord relationship. Tenant-landlord relationship will put more burden on you. If they decide not to move out then you have to go through the eviction process. Without the relationship, you can just boot them out after the thirty days.

The lease back generally involves some nominal per day rental fee (typically monthly mortgage divided by 30). Again its set so that its not based on monthly rate. This is the norm instead of lowering the selling price. I think there are some legal reason for doing this.

Do check with your agent and broker on how to do this in your state. Milage will vary!!
