I'm betting the advice is from his attorney and if I can speak with him/her that will clear up a lot of the questions I have.I'd still prefer a straight up purchase, but if I can get an iron clad option agreement, that may work too.

If there has already been a discussion that I didn't find feel free to post a link for me.My duplex was built in 1951 so I chose to leave the cast iron tubs and refinish them.

I've used 3G Plumbing and Backflow to replace 80ft of cast iron.

Ironically, I found my current home as a Realtor, and paid myself.

This is not current code.With relation to plumbing, the risk is many of the pipes back then were cast iron.  

Seems like cast iron but MUCH lighter and cheaper.

On your situation, it is highly unlikely that a discount will be paid back, quality of work has no words that could even start to describe even on an iron clad contract.

(right now, ironically, I'm reading "Evicted"). 

It's a enameled cast iron sink.

And the data, in some of the specific areas cited in the study, overwhelmingly points to *something* going on, where, say, in a community that is pretty diverse that a bank will somehow wind up making 97% or even 99% of its loans to white people.As to some of the people saying that it’s “poor journalism” (which is kind of funny because a research paper isn’t really journalism) or the study can’t be valid because they didn’t include credit scores, I find that really ironic since it’s the lenders themselves that don’t want that information made available even for academic purposes.
