After staging, it was sold to a retail buyer for a strong profit, demonstrating the potential for significant returns by buying from motivated sellers, renovating strategically, and selling at retail.

The home was then sold for a profit, providing a strong return on investment.

I think you need to find a property that is being sold significantly under retail to build in a lot of equity.

My PM includes any invoices for repairs in the monthly statement as a line item.

Are these the only items we need to document?

However, they should be saavy enough to understand that the valuation of the house is based on what similar properties in the area over the past 6-12mo have sold for. 

I have sold a couple to investors and some to occupants and can't say I have anything to complain about. 

Did you give her written permission to store personal items outside in a common area?

In that case when a rental lease expires or a condo is sold, its rental exception is extinquished.

My advice would be to underwrite as many house hack opportunities as possible and assume 100% vacancy + a large capex item so you stress test your worst possible scenario and can you get through this.
