I acted as the GC on my house when I built it in 1987. I was 30 years old, and didn't know anywhere near what you do, but very successfully hired all of my subs and did as much as I could myself. I was a lineman for the power company, so I was always around new houses being built, which gave me the opportunity to see who was good in each trade and who wasn't. The relationships that I built with those folks made it easy for me to find GOOD subs who would show up when they said they would and do what they were good at doing. From the time the equipment unloaded to dig my basement until I had my CO and perm electric on was 6 months. I saved $26K over my cheapest turn key bid....but remember, it was 1987. I did the same with my detached garage when I built it in 2007 and saved even more. If I could find a good acre or two out of this bright blue county we're in, I'd do it all again at 68 years old....but might die from sticker shock comparison!
Hang in there, the rain will ease up so the wood butchers can start framing!
