I had a friend whose house had major structural issues as an underground pipe wasn't sealed off. 

One of the restroom water pipes broke over the weekend and flooded the whole office that would need a major renovation.

The only thing that occurs to me is to check the pipe under the sidewalk that goes from the meter to our shutoff valve.  

You need him out ASAP or squatter starts removing the copper pipe, the mantle, the stove, the HVAC is probably gone.

We decided to buy up to the bigger 4/3 fixer house in the cornfields, and the leaky pipes (and now 4 kids total!)

Pipe was fine..

Because I run a business and Uncle Sam is up my tail-pipe with a microscpe BUT also because the state and commerce dept/ require great records to assure our client's are being fairly treated and legally served.

The drain pipes were fitted into the main clay pipe and concrete was poured around the edge of it to seal it.

We don't want to hand it over to the ones we did not like, as it may become more of a headache.If someone could advice what can be done next, would really appreciate it, feels like our options exhausted, but i don't want for the house just hang in there, eating interest.

It is a very protracted and complex case, but I shall summarize best I can:- husband caused the fire and committed suicide- insurance claim denied due to arson- wife filed bad faith claim against insuror under innocent spousal relief argument- insuror still refused to pay claim- wife exhausted all resources; abandoned further claims against insuror- city deemed property uninhabitable and issued demo order (lien)- property demolished along with the solar panels- husband was the sole lessee of record on the solar lease- wife submitted death cert to solar lease co.- bank just recently issued cancellation of debt to wife for 1st mortgage- wife wants to wash hands of it all and sell vacant lot to meMy discussions with the public adjuster I brought on the case was that since the property no longer exists, the solar lien is wiped out, but I'm not sure.
