re: Anyone ever been their own GC for a new home build?

Yes. If you’re willing to visit the site daily/frequently and also oversee milestone events like concrete pours and you have flexibility with your job that you can visit during the day if there’s an issue, it’s not bad.

Do you know construction/are you mechanically inclined? Having someone with contacts in your pocket like you said you would have is a plus. Plus you can do some work yourself if you so choose.

I don’t buy into the myth of “contractors won’t work with you” or “contractors will charge you way more.” If that’s the case, you didn’t want them in the first place.
