I would simply give notice under your state guidelines, inform tenant and their handler, and let them decide if they are staying or going.

Once you figure that out it should help guide you in your next steps.

I agree with the others on month to month only so things can naturally shake themselves out with those who want to stay and those that don’t without being bound to people who want to make your life hell!  

@Brian Stike  After 6 month you can cash out 75% of appraisal value if its 1 unit but for 2-4 units  stay 70% of appraisal value.

After about a month our servicer made contact and found out the borrower wanted to stay in their home.

The fact they are complaining online might be an indication the property manager dealt with them properly so be sure to ask the manager for their side of the story.I hope this basic guide helps.

@Justin Klepfer glad you have someone that can help guide you through the process.
