re: Self Contract New Home Build.

If you decide to do this, or maybe even during the decision process, talk to as many potential subs that you can, and try to get them on your side before you even start.

Perhaps their confidence/recommendation that you handle it yourself helps their attitude to help you make it successful.

All that said, I hired a GC and his fee was 10%. His foreman's experience, and his relationships with their subs was well worth the 10% to me. Several of the subs had to come back to clean up their own work, or to clean up work that was messed up by subsequent subs, and they may have been more resistant to at my request. I suffered none of that friction.

Best of luck, and enjoy the process whichever route you choose.
