Then I always have something scheduled to do like cleaning or installing blinds just in case there's any down time.

My drywall guy stays busier with more work than he can do but still found time to send a guy in to get the addition done at my house this spring, because not only do I keep him in work, I don't tend to have hard deadlines and let him work jobs in the down times when he has a day or two free here and there.

I've got random downtime at work and in the evenings. 

I would create too much down time in between mailings. 

With any down time , I do mentor others agents (for free ) if they’re truly open minded.

This way you never have to worry about what to do during your down time, because you wont have any, you can really focus on RE on your off days and when you find there isnt enough time to accomplish your RE tasks, you can start to devote more time to it. 

Will reduce downtime and produce faster renovation of property.

However, with the difference in rate you can charge being turnkey in most cases it makes up for the possible downtime.

Maximize your downtime. 

One way to get started is to attend some of the networking groups when you have downtime and are in the area.Here is a list of some in the area.Please note I am not affiliated in any way with any of the groups other than that I have attended some of their meetings/presentations.NTAREI- https://ntarei.com/ Normally meets about 2x a month in North Dallas at the Holiday Inn at Preston and LBJ NE corner.
