From that area, it goes to another very inadequate pipe and flows down to our other neighbors' property.

Burst pipes are not fun! 

For example, lead paint, asbestos, lead pipes, etc.

If you have a dryer get the exhaust vent cleaned out.

It has no HVAC system and no insulation, I would guess the copper piping has been stolen (worst case scenario).

Id like to be able to replace $70k+/yr with REI...Realistic or pipe dream?

Pipe dreams perhaps, but if someone is going to go in there guns a-blazing, maybe it'll be me?

The format is ASCII with a pipe delimiter.

There was water damage from a pipe burst and some of the drywall and flooring has been removed by what the seller is calling a "professional company paid for by the insurance company".
