Neal .. like your insight! I have a word for the way you operate - it's called "integrity"! Bud, I totally agree with all you said in your response. My house had "upgraded" wiring. The basement and first and part of the second floor had been replaced. The attic wiring (which supplies the second floor lights and receptacles) has knob and tube running everywhere. Also, in the basement, there are a whole bunch of junction boxes. I've discovered that many of the boxes had the ground wire twisted together with the neutral! The upstairs bath had been added after the house was built, and the plumber cut every one of the floor joists to run the drain pipe. I would have never discovered this if we weren't rearranging where the fixtures go. When I was a kid, my dad drove a taxi. He would actually stop at junk piles (back then, you set out "everything" for the weekly trash collection) and pick up old fans, lawnmowers, etc., and fix them. As a kid (10 years old?) he taught me to work on things. I have always viewed anything mechanical as a collection of "nut and bolts" - it's just a matter of "how" they are put together! I am NOT real familiar with construction, but am willing to tackle almost anything and am figuring a lot of this out as I go along.
Unfortunately, a lot of people have no ability whatsoever to even assess if there is something wrong with a house, much less fix it. For example, my wife can "demo" most anything in our house (and has been a great help to me), but if something happened to me, I don't think she could "fix" anything besides paint or wallpaper on her own. The faucet our friend left would not be a problem for me - I would get another one and have it changed in a half hour. It's just the fact that he wanted to hide it. But, whoever bought the house might not have the abilities you and Neal and I have, and would have to PAY someone to fix it. I don't think this would've been discovered in a normal house inspection, either. Not like they're "looking" for glue on anything. I think the least anyone can do is tell a buyer about any problems with a house. Then, they can decide if they want you to fix it, or pay someone to fix it, or move on to another house. It's referred to as "Do unto others ..."
