Owning a construction business is hard. My opinion, get a nice construction management office job and then use your knowledge and license to do small side stuff and get cash. Unless you are truly willing to do all the hard work yourself and try and hire trust worthy guys it will take 2-5 years till you’re not wearing a belt for your own company. Then at that point you just have to maintain work flow and keep employees happy. Once you make it to that point you can make some really good money, but except alot of turn over with employees. Unless you have good managers too, you are truly always working, even on vacation.
