Cash for keys for owner occupied duplex

[Jonathan Boyd]

So I'm closing on a duplex in Northwest Arkansas in a week or so. Both sides leased month to month, and we plan on moving into one side. We're taking the side that is worse off to allow us to fix it up, but I need the guy there to leave. I know I only need to give him 30 days, but my concern is his actually leaving and the condition the unit will be in. He was at the property when I looked at it with my realtor and STRONGLY expressed desire to stay (just shy of begging.) I would never have rented to him in the first place, plus from some of his own admissions, he wouldn't currently qualify for our lease. I don't want a trashed unit, so I considered offering cash for keys, and even a daily incentive (like an extra 10 bucks for every day less than 30 he's there). And of course, returning his deposit if the place is in order. Any thoughts or advice? Thanks.
