Depends on if you are literally building it mostly yourself and are the GC or if you are having it built for you. The biggest problem we have is that our build got delayed by 6 months because our original bank was a complete cluster F! Timing is everything. We had to constantly tell the subs that we planned on using that we were still delayed, lost a couple of good ones after awhile because we had to keep changing the start date. Now we are trying to finish a house in literally the busiest time of year for us job wise. Our initial "house designer" was a waste of time and money. She was hired to take our rough sketches and layout to a finished draft for our use. She was more interested in putting imaginary digital furniture in house to show us how it looked. In the long run our lumber yard has a couple of guys on staff that could have done the plans in house and saved us a lot of money. We had to eventually due that anyhow as she had made so many mistakes. I originally had a plumber hired, but after he did a terrible job installing the below basement stuff, I fired him and have done the rest of the plumbing myself. Took forever to get a reasonable bid on septic system install and then had to wait 3 months for him to come do the job. Great guy, just a symptom of the lack of enough workers in some blue collar fields. I will put a list together when time permits. Overall though I think things have went pretty smooth. My wife would say the hardest part is picking out the damn paint and tile! Way too many choices and that in itself gets a bit tiresome.
