This is a typical roof drain.

You tried getting a roofing job from Bob Prisco aka Bob Stevens, or you tried getting a roofing job from Elliott Taylor?

I had one that also did a flat flee for leads but there are other ones that do auction style.

If no, are there photos of each unit and all closets, the basement, the roof, the exterior, and all mechanicals?

Flooring, Drywall, refinish basement, roof, gutters, tuck point around house, and one full bathroom gut all had to be completed. 

It's simple to install over a flat floor.  

You asked about buying older properties and the biggest issues I have found is that roofs need to be replaced, HVAC needs servicing/replaced, and sometimes there are foundational issues (not super common). 

I live in Georgia and the hurricane destroyed the roof.

Most likely because of their attractive flat fees!

As Hurricane Helena went by, both of the roofs got damaged.
