I couldn’t imagine having to deal with calls about them, struggling tk find repair people, finding new these days or arranging to have them delivered.

They are friends and this arrangement has worked out great: I’m not depending on one tenant for the entire rent amount and they have affordable housing.

Property is arranged as a detached 1 bed/bath unit (occupied by inherited tenant) and a duplex: 2 bed/bath owner's unit & a vacant mirror unit.What made you interested in investing in this type of deal?

Most people in the solar industry recommend going with a new roof and traditional solar panel arrangement.

The only challenge with this property was organizing a cash for keys arrangement with the current tenant to give them extra incentive to move out in a timely manner.

If so, sure, if not go with #2.2) Seems like a great option.3) If you are giving notice to the tenant, then you likely don't need the code, they could meet you there or arrange to leave it off.    

With this rent to buy arrangement, will you be able to evict him?

It always happens that the number of listings gained out pace the number of buys simply because the vast majority of people are going to sell traditionally.If you aren't up to outsourcing or mounting your own campaign, you could always work out an arrangement with local wholesalers who talk to a larger number of people who want to sell, as opposed to "needing" to sell. 

If the wholesaler closes on the deal, then maybe seller financing can be arranged with the end buyer, but I don't see how their assignment fee would be included in the transaction.

I have the floor layout that indicates the seating arrangements in my listing as well as photos that clearly show how things are laid out.
