A primary home is not an investment, as it's not producing you any return other than appreciation which you have access to only selling or taking out loan.

Like many (most) businesses it requires an investment of capital; money expenditure for ongoing marketing; management of operating, marketing and professional personnel; keeping accounting records and filing tax returns; established sales practices; constant monitoring of goals, budgets, and productivity; establishment and implementation of operational systems; and providing customer service.  

I think if it's vacant 30 days, then a homeowners or landlord policy will deny any claim filed.

(a) Any person offering to redeem must pay to the then holder of the legal title the value of all permanent improvements made on the land since the sale, and if the holder of the legal title cannot be ascertained, payment may be made to the circuit court of the county having jurisdiction of the subject matter when the complaint is filed to redeem.

I wonder if the tax forms would be mailed there, and then that trust company will file to IRS to explain it is tax exempt? 

Since then, she has sent the keys as agreed but hasn't produced the payment as she promised.  

This must produce positive cash flow to protect downside. - Understand the upside of the "rent by the room" strategy- Understand the upside of any repairs that can be made to the main unit. - Understand the cost/value of completing an ADU project- Underwrite mid-term and short-term upside cases as well. 

So I had to file for a dispossessory proceeding, but it was short lived because I received rent from him on the 15th of the July.

I did some digging and they had been operating for a long time and had numerous complaints filed. 

File all receipts in a dedicated Google Drive folder.
