Please provide the necessary documentation no later than [DATE/TIME] or confirm your intent to terminate the current lease and vacate no later than [DATE/TIME]"That's a very simple example, but gives you an idea.I also recommend you make tenants responsible for improvements, that they be at tenant cost, and that installation and/or removal be done professionally with receipts as proof.

Obviously, if the tenants fail to timely pay rent, you can enforce their obligations with a notice to pay.Your question is legal in nature, so I recommend that you consult your landlord or FHA attorney in your state about it.

If so, any recommendations?

I would recommend you talk to a landlord-tenant attorney to get the best way to terminate the lease.

While this is not unique to foreclosures, and should be done for EVERY deal, I highly recommend you get full title insurance on a property.  

I am looking for Property Manager recommendations for Evansville, Indiana. 

If possible, I would recommend taping into some groups that could help you accelerate your growth.

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

Any recommendations on trustworthy people?  

As a starter, I recommend reading “Long-Distance Real Estate Investing: How to Buy, Rehab, and Manage Out-of-State Rental Properties”(if you still haven't).
