UPDATE 1/14: You know, after receiving all of this advice, I decided
that certainly getting the plumbing fixed would be a very good idea. I
called my Plumbing company and a journeyman plumber came out this
morning. I paid $313.00 for him to come out, go down all over the
crawl space and check each drain. The entire water system was
pressurized to find NO PRESENT LEAKS!!! So I just paid out over $300
bucks to be told that there was no problem.......I'm pretty fried. The
plumber told me that it wouldn't be ethical of him to suggest fixes
when there aren't any. Despite this information, it looks like the
buyer is going to walk because a: she doesn't belive the licensed
journeyman plumber.....and b. I won't fix the foundation. Which, upon
looking at the inspection report, the foundation was rated as "FAIR",
with settling typical for a home this age!!! Go figure. But she wants
it fixed. Well, take a hike quickly please so I can get my home back
on the market...I had another showing today, despite the fact that the
house is tied up in the contingency phase.
