Question involving time spent at a job site?

[Hunter Harms]

Over the past few months I have been learning and becoming well versed on the rehabbing and flipping of REOs. I am ready to start searching for my first deal and I had a question I can't seem to find the answer to.

When working with a GC who is managing my entire rehab, how much time should I spend at the job site? I want to be hands on and be in control of the deal, but at the same time I want to let them do their job and not be looking over their shoulder the entire time. I was thinking it would be best to show at random times throughout the day and switch it up every day so I am not predictable. Also, when I'm on site what would I need to be doing besides making sure everything is in order? I would definitely want to learn the process hands on by asking questions and observing, since this would be my first flip, but what else needs to be done when at an active rehab site? 

Thanks BP!
