It would tell me how much electricity was consumed by Unit 1 during the month. 

Unfortunately, it's not possible to tell the difference between an insurance agent being whimsical on purpose, or making a genuine error, as a consumer (or mortgage broker, for that matter), but being 1/3 off makes it look like a genuine error to me if I were to place a bet.

It can be very time consuming and very expensive if you make mistakes.

I don't want the properties to depreciate, but I also want a healthy cash flow. 

This is but a few of the major things we look at to be sure we are providing our investors with a solid investment that brings healthy returns.I would recommend starting local if you're just starting out.

People complain about Illinois and there’s plenty to complain about, but rents are pretty healthy.  

This is for investors, not personal consumers of real estate.  

Assignments, MBS, etc Check how that market is doing, if it is healthy or is showing signs of trouble.Prior to the 2008 real estate crises banks were very active on that domain, and I particularly recall Deutsche Bank selling pools of motgages, and doing securitizations all the time.. they got rid of as much loans as they could and then the bubble bursted. 

Well long story short,  the seller got wind of his master plot to rid the property of the healthy vegetables and refused to speak to the buyers agent.  

In Brandon's book, it seems that rental property investing can be a very time-consuming process.
