The regular numbers you might collect for Cap ex and Maintenance might need more of a contribution than a home without settling issues. 

After refinancing, offer tenants owner finance and wrap my own mortgage, collecting a 10% down payment on the new ARV.

For 10% of the rent per month, they'll usually handle everything from marketing the home, showing it, drawing up lease agreements, extensions, rent collecting, maintenance coordinating, etc. 

Substantial services do not include the furnishing of heat and light, the cleaning of public areas, trash collection, and such.When extraordinary services are provided, the rental is treated as a trade or business and reported on Schedule C regardless of the average rental period.

The SLREIA and Utah REIA meetings have a lot of collective experience.

Just because you can do something does not mean you shouldAs to whether a tenant will actually collect? 

I don't see how they could send a collection agency to you or anything if you didn't sign anything with them.

Every month he sends the payment after collecting their shares of the bill.
