The savings is just a math problem that will depend on what kind of lights you are using, what your electric costs are per Kilowatt hour. if the sensors save you 1000 KW per month at an assumed cost of $0.12 cents per kilowatt hour...should save you $120 per month....no clue if those numbers are good assumptions.

I can always do some fun-with-math calculations to see if there would be a nice balance of casho out plus the non-FNMA loan to cover the rest... 

By June 2019 I expect the cash flow would be positive ~$400 but have not actually looked at city wide rent increases in that time (I know all of my tenants got rent increases).The higher appreciating cash flow area will always catch a slower appreciating cash flow area given enough time (it is simple math). 

That is the financial side, but only the math portion. 

WEll your a smart kid  just do the math.. simple as that don't need to ask the internet.. 

The math looks like this.
