Wow! Sounds like you took on a lot of work and have done well with it, Bud.
My family purchased a house that had a LOT of hidden problems. Some of which took almost 30 years to come to light. One was that the septic tank was insufficient (it was put in when this was a one bedroom house and never updated when two more bedrooms were added) and the field lines were done incorrectly. We just had to rectify that a couple of years ago. The plumbing jumble is a mess for a different thread. LOL.
I wish you lived in my area. A friend of mine passed away and now his yard with two houses a workshop, and greenhouse, and some storage sheds is sitting empty and for sale. The real estate agent blows and the market here is terrible though. Its in need of a roof replacement and mold remediation now. Plus there were a few break-ins until I installed an alarm and very loudly announced around town that I was going to be sitting in the house with a shotgun waiting for the next break-in. That seems to have done the trick.
Something I will say that I've learned when shopping for homes is to check the crime rate in the area and talk to people in surrounding areas-- the real estate agent won't want to tell you the dirt. We saw a house that my mother wanted to buy and the price was right, but I wondered what the catch was. Turns out there are TWO Mexican cartels operating in the area, more registered sex offenders than cops, and the crime is so high that Fedex has a standing policy to not deliver there after dark (since a cartel killed one of their drivers and hijacked a truck once). Tip: Stay away from the Meadow Lake neighborhood of Los Lunas in New Mexico.
Is there anything you can do to keep critters off of PEX? I've heard that there are certain bugs that will eat it and that mice will sometimes chew through it. Despite having 14 cats, mice are an issue inside the walls and in the attic.
I forgot to mention that I LOVE the cathedral style raised panel doors on the cabinets you installed.
