This would be a VERY inefficient method and leaves me wanting to just send that list out to a different mailer service.What is everyone's thoughts?

I'm not 100% sure about each one's different benefits and cons, but which method would you recommend to use if you were in my position?

Currently I view real estate investing (REI) as a method of generating additional income apart from my 9-5.

I ended up going with a market I had already been to, Huntsville, and learned to do long distance real estate investing as well as the BRRRR method.

Also, do you have any idea what you'd like to do in terms of the method of investing? 

I know very little about legal precedent but I'd expect the major meter manufactures (selling into the utility space) to be well incentived to challenge these items best they can, and they have money.Here are the issues, and the reasons that the difference between an air forced system and a boiler/hydronic system are not meaningful for this discussion (ie efficacy issues of sub metering exist for either when method of measurement is measuring heat at point of delivery):In either case, the blower (or pump for a boiler) is the method of 'moving' either air (central air) or water/glycol or equivalent (boiler etc). 

@Spenser Harding you are right on the money, and speak from the perspective of someone who has invested using a variety of methods + gotten in the trenches with a BRRR.

Some recommend the STACK method also.

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

I understand that BRRRR would provide more cash flow, but from what I've read this method also requires more time and investment.
