They usually grant 10 days for payment, on the 11th day you file possession - then another 10 days and locks are changed. 

The property isn’t guaranteed vacant, so you may need to handle post-sale possession if occupied.

@Isadore Swartz I know they left early they turned over the keys when they were transferred so I had possession.   

- Does the seller need post-close possession?

By chance do you possess formal education in business analytics?  

This serves as an indirect reminder to the tenant that you will be paying attention to what is returning.Prepare if they Go Over: If the tenant is still in possession of the apartment after the deadline, be ready to serve official "Notice to Quit" or "Pay or Quit" documents, as required by statute in the local community.

Honestly this prospective tenant sounds like a nightmare.If they are nitipicking this much just to get IN, you can only imagine how they will be once they have the keys and have possession rights.Turn around and run lol.

If the funds are in your direct possession at any point, you will likely lose the tax deferment.

If you still proceed, use a written agreement, get possession terms in writing, and avoid letting sellers stay without a clear, enforceable exit.

All of these pre-possession payments must be in cash.
