Of course, human beings have problems they cannot choose like illness or accidents, but actively choosing the life you want to lead, knowing you are taking on the problems that come with that life choice, can make it much easier to bear the problems that arise like, for me, tenant issues or a delay in closing or down time when you have to save for a down payment on your next rental and it's taking longer than you want.

Managing on My Terms: Being in control of my Airbnb property management allows me to decide when I want to host guests and when I want some downtime.

I work in local government specifically in Parks & Recreation and the job is a lot like the show; very uneventful and there are countless hours of downtime.

Cap rates of course will vary based on how strong the location is ie does this location prosper even during downtimes when other nearby areas suffer more?  

B) More properties more down time for example: if you had 12 properties (12 months) can we reasonably agree that theoretically every month you would have a turn-over; or another example if you 20 properties can we reasonably agree that every year you would be paying for a new roof on a 20year shingled roof.C) there will likely be a snow ball opportunity which will increase and/or speed up projections.

This would be my approach when I have downtime, but I wouldn't be doing it in place of productive activities if my day needs me to get to them. 

Both preventive and predictive are proactive maintenance with the goal of reducing breakdowns and reducing downtime. 

When in a fund you also have "all" your funds lent out all the time earning interest, vs. when you buy "one-off" trust deeds there being down time when you are searching for the next trust deed to buy.  

Having markers out in different areas has worked well for me over the up and down times. 

Do make sure you buy at a discount though, or at least improve value, that will help you in down times.
