There's multitasking, and there's chaos...what you just wrote is what I would describe as chaos.
The first thing you need to do is to realize your time is the most valuable asset you have. Don't waste it being a PM, or doing your own rehab. If you want to expand to the next level, it will demand more of your time doing things REI must do at those levels. You are at Level 1 out of at least 10 right now. Your Level 1 may seem higher, but you appear to be just doing a lot of things at Level 1.
Delegate. This will compound your time. Set up systems much like a production line. Take smaller % of more assets. Manage the assets.
I could not agree more with what Joe said. I use to do all the deal hunting, research, swinging the hammer, screening tenants, property management, daily maintenance/inspections ect. In the last few years I started delegating those task and it frees up a lot of time to do stuff that your employees or subcontractors cant do. It takes a little from your profit, however it allows you to get more accomplished faster which in turn can make you about the same or more money in the long run.
