I agree with both @Tim G. and @Cody L.
The ability to find deals is highly valuable, any investor will tell you that.
I did the same thing as @Cody L., straight out of architecture school, I wanted to go into real estate so I asked someone I knew who flipped houses to throw me on with his crews. I worked alongside professionals as a "helper" With pretty much no construction experience, they put me on the dirty grunt work, cleaning rat poop, removing the old toilets, scrubbing down baseboards, etc. but as I was doing that, I was watching every single thing they did, and pestered them with tons of questions on how to do things and different techniques. I would ask them to try stuff and absorbed everything I could. I worked with literally every single trade.. plumbers, electricians, framers, painters, carpenters, masons, roofers, etc. I learned it all.
6 months later these guys were working for me on my flips.
I find the knowledge in construction to be both highly beneficial but can also be a vice. It helps me manage my rehabs efficiently, identify when a sub is trying to take shortcuts, performing subpar work, or just trying to take advantage of me. The ability to perform the work myself also allows me to absorb unforeseen surprises/expenses by doing it myself. But, It has been a vice for me because I would try to do more than I should myself, and I end up working in the business as opposed to working on the business. I would find myself spending my time installing cabinets and baseboards when I should be out finding more deals.
