There were young guys in peak physical condition that would melt like chocolate in Death Valley the minute bullets start to fly.

They do where they have physical presence, for sure.

So I understand the owner loses right to possession once some body buys the tax certificate?

May need a physical inspection, which is ordinary course for many owners.

Needless to say none of this happened over the phone, I had to physically be there to see the code and explain this to them.

I had to deal with a lot more issues than I've ever had in non-S8 rentals like extensive property damage and also bed bugs, roaches, drain lines completely clogged up by grease (I learned what sewer worms are, look it up), spray paint art on walls and food on ceilings, noise complaints, police at the property, removing dead bodies, etc.  4.

The only way a seller would have that information is if you physically provide it.If you have only disclosed prequalification through Lender A, you would only need to provide a denial letter from that lender.

He was mentally not as sharp as he once had been (but fortunately was still functioning well mentally, his issue was almost all physical which may be even more frustrating). 

First of all, their certification program is NOT accredited by any legal body so it is basically worthless other than it may look good on your wall.

It sounds like you are looking for an employee as defined by most taxing bodies.
