Cash for keys to close on a owner-occupant property?

[Mark Douglas]

Hey BP,

I've got a potential deal I'm considering: 3 units (all 1/1) for a good price (still have to test drive the neighboorhood). All 3 units are rented, but I'm going FHA, so I need to live in one of them.

If the seller can't/won't vacate one of the units before closing, what are my options?  

Side note: This is my 1st property, and I'd love to avoid an eviction this early on :) 

Thanks !
