I've looked everywhere for a solution and this is the best I found - it's a sub-metering system that can be installed so that you know who is using how much, and you can monitor remotely: http://www.ekmmetering.com/remote-water-and-or-gas...You'll have to find someone savvy enough to install it, but the system is a few hundred bucks, well worth the investment to avoid the headaches.I haven't installed the water sub-meter yet so I can't say how easy or difficult the process is but it looks promising.Good luck.

Any other suggestions on how to prevent these instances from reoccurring short of having them apply before I show the units?

Monitor and Adjust: Continuously monitor the performance of your investments.

I’ve gotten remarried, moved to Michigan and I’m starting a practice here when somehow I receive Freedom Founders Fodder in the mailbox at my new snail mail address.Clearly the result of un-monitored infusion soft-ing as I’m the last person Freedom Founders would be getting to respond to the full color multi-page mail piece.

We were talking about risk-tolerance, and he mentioned he frequently monitors his whole investment portfolio to make sure he doesn't have too much in RE.  

But come late September Jeff will be right beside his team in the trenches 8 hours per day, monitoring, delegating, working, organizing and treating the houses like they are his. 

It can be great investment depending on which types of liens they are, how much are they each and are they reoccurring daily?

That certainly aligns with what I keep repeatedly hearing and reading from experts and others who have found reoccurring success in this.

How do you actively monitor and keep track of the market?

Make sure they throw everything they own away and have them sign something that they will pay for all reoccurring infestations.
