How do I properly lease a room for a househack

[Jaziel MaldonadoRoman]

Currently in the military and I'm do to close my first single family in the next couple days. I have a fellow member that's I'm going to be renting a room in the house for and would like to set up a proper lease agreement and possibly run a tenant screen (I assume would be necessary for legal purposes). What are some other things I should be doing or setting up to protect myself legally and financially.

*Lease Agreement

* Tenant Screen

*Checking/Saving Account for rent

*Insurance?
