You are providing someone with a home so make sure, house numbers are clear in case of emergency, all window and door locks function so you can't get blamed for a robbery, document that the water heater is set at factory setting so no baby gets scalded, document there are no trip hazards, document there is no danger from falling/dead tree limbs, no culverts a child can crawl into, no access to the attic that can cause a fall, that the garage door safety features are working, that there is a fire extinguisher(required by insurance btw), and smoke alarms that work, etc, etc, etcHave tenants sign that they will have and hold renters insurance and document EVERYTHING as far as maintenance, complaints and resolutions etc.

I have talked with her multiple times and did some problem solving, she's a manager at a Dollar Tree.  

I know that we'll need a CPA to get official advice, but I'd like to have a general idea of how it goes before going into that meeting.1) There are a lot of expenses not relating directly to the construction of the home, such as permits, construction of utility lines, tree clearing, surveying, etc..
