Welcome back Gary. Love new locations and a change of scenery but hate the moving process.
As for new construction, I was at my new house site every day while it was being built and have to say it saved us a ton of headaches. Decisions were made on the spot, improvements were discussed and implemented, and no shortcuts taken. I had an excellent builder and he didn't require that close observation but as the crew quickly discovered it was a good thing for them as well and we got along very well without a hitch. I was the general contractor and the company I had worked for was doing all the mechanicals (HVAC, electrical, and plumbing). I was also able to do a photographic documentation of all of the work. I know where every pipe, wire, and stud is located. May seem excessive but I had just had knee surgery and this kept my mind off of other issues. In fact while the house was under construction a friend of mine and I were busy building the roll off roof observatory for my "other" hobby.
