I consider him an essential part of my team, and I regularly ask him questions when things get dicey with tenants.

Here are my two cents as a CRE Agent: Often times with off-market opportunities, the seller is not actually signing a listing agreement, but rather waiting for the agent to bring them a prospective buyer or LOI before signing any paperwork.

The attorney did find the paperwork from Wells Fargo with the foreclosure stating they did a good faith investigation to find the heirs back in 2007 and none came forward. 

There was more paperwork involved with this one, but it was all worth it in the end as these are long term investments for me.

Swimming naked essentially.

Someone might want it for parts or even a hunting cabin in South TexasSince you say it is on lots, I am assuming it is real property so it would be sold just like a home with a little extra paperwork(Statement of Location)

That (essentially) means you're leaving money in the deal so no additional down payment.

RE is considered essential business and it's allowed to have people tour the house with PPE and social distancing.

But I do think your post was a little inflammatory:You essentially asked If the pandemic has put you in a bind, "were you even a good landlord in the first place?"

Essentially you cannot move a tenant out unless they are damaging your property and even if they are, it will take months if not years to get them out.
