I know that's what you started this thread for. 

Tenants save money when using a shared meter, so there's plenty of room for error when calculating how to distribute the charges.

I'm often surprised by the things tenants due to save a quarter.

I wanted to help them out and minimize their loss and saw an opportunity to get a property slightly below market because of my commission savings, immediate mortgage and maintenance relief, in addition to keeping a lower short term interest rate How did you find this deal and how did you negotiate it?

I will add that you definitely do not need to be near your investments, but it makes things a lot easier when you first start off. 

This is where things will start. 

Are they going to start paying down that credit card debt, turn over a new leaf, and avoid bankruptcy for the next decade? 

In one of my markets assessments are performed every 3 years, and the cost of 3rd party appeals will cost 30% of 1 year savings. 

They asked me to empty my savings, max out cards and then finally to take out a loan.

For instance, many tribal lands are exempt from state and local property taxes, which can obviously lead to significant savings.
