Take what you can from something ( a book life music etc ) and use that as brain fuel apply your life and the bigger picture and move the best way possible always expanding don't discard something that someone gives just because they stop talking about what " you" were expecting.

My career is in the music industry and I am constantly on the road because of it.

When you want deeper understanding about contracting, specially paper contracting, types of contract, how to manage a contract, how to read plans, how to compose a scope for subs, how to manage subs, what constitutes a change order, what is a legible CO and what is not, etc, then you are looking for a Construction Management Certificate (this too is a couple of thousand), I would suggest on-site course instead of online since you are new to trade works, this will be your biggest investment, but it will also be your biggest asset, maybe this is a 1-2 year course, be sure to pick everything you need first.

I manage all of my rentals with a regular day job, a regular part-time job, and a fairly active music hobby, and still manage to get in family time, etc.

I've been a music educator and musician for the last 10 years, in which time I've also started a music studio, as a small business.

I play musical chairs with my HELOCs much the way you might with credit card balance transfers.
