The standard sell it and rent it back for 4 years is probably the best bet.

If the lender contests the funds release and don't choose to release the escrow funds back to you, it can get tied up in litigation and after 3 years will be surrendered to the state by the title company.Your best bet is to go with a legitimate company that will be up front and transparent with you about the terms and costs before you are already committed.Seems like everyone is telling you the exact same thing so I really do hope you make the right decision here.

You can bet they do quality work or these huge companies would not be hiring them. 

A cattle guard was going to be my other suggestion, but I'm betting those are pricy.

The owner pays for all the bills currently 575 per unit, which include water, electricity, internet, and cable.

Your best bet to pricing the unit right is to look at the comps and see how fast they've been renting. 

@Andrew CarlsonSounds like she’s running a business and I bet that’s against your lease agreement.

I have also bought from a neighbor and such but unless you have some boots on the ground, your best bet would be finding a realtor you like and/or search the MLS. 

Your best bet is definitely going to be a small credit union or regional bank in that area. 

I bet the filter is clogged
