I'm actually taking a vacation to Phoenix X on the Floribama line in June and part of the reason for that is to check out the property/area.

As far as why it takes time to scale - the most common slow down I see is the time it takes to find the next property that checks all of the boxes to be a successful BRRR with numbers that will work. 

Most sensors need to be connected to wifi and checked on every once and a blue moon.Is the best move to mandate in the contract that the tenant maintain those connected sensors and connect them to the wifi they pay for?

A downfall of this process is the lack of tenant screening (background, credit, eviction checks) as far as I'm aware of.

I’d start with checking on their compliance requirements.  

@Shubham Aggarwal I am not a100% positive, I would double check with your broker!
