Somerville does not want people digging down too deep and using sump pumps to drain the earth around them.Not sure how to answer your question about how the buildings and foundations are connected.

Agree sue the new owner they are trying to slip one by you what do they have to lose nothing.You need to help your lawsuit get an expert to give you estimate with great detail, offer to pay them some money for the report don’t try to play tight wad and get a free estimate that looks weak.The cost may not be earth shattering hard to say.

@Maria Teo Unless it is leaking in front of the inspector I don't see how on earth they could make you re-pipe the whole place.

Seems very personal and down to earth.

What if the seller loses everything and/or drops off the face of the earth or worse, and the new "borrower" needs information on the loan?

Where on Earth is this place?

Or look at Google Earth street view. 

hard to be sure in this crazy era we live in but as a potential/consistent buyer in okc i would love to see prices come back down to earth a bit. 

How on earth are we paying our loans?

Why on earth would a PM even suggest that?
