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). 

On another note, I am vigorously researching construction methods for the new house, and also chipping away at some concept drawings for it.

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

Some recommend the STACK method also.

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

I’m looking for a structure that would at least allow me to break even, or create capital through something like the BRRRR method to use for future deals.

What alternative method(s) would you recommend for beginners? 

@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.

We did the BRRR method and house hacked. we lived in one unit and rented out the other.

Before Baselane, I was dealing with a mishmash of payment methods, including cash, checks, Venmo, PayPal, and Cash App.
