How to Avoid Mistakes While Building a New House?

[TomBrown]

Hello everyone, I'm lucky enough to be building my new house soon, and I want to be diligent to avoid the mistakes so many people make in the process. I've heard of projects significantly over budget, delayed, or worse due to minor planning mistakes or miscommunication with contractors. Some friends of mine have recommended doing what is one of the best things to do at the beginning of the process consulting estimation companies in USA is to breakdown accurate costs and material lists before getting underway. That way, you can avoid surprises later about your budget. I'd love to hear back from people: What did you do or wish you had done to not run into expensive issues during your construction? Did you verify contractors work, hire experts, or follow a specific checklist?
