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). 

A couple years back, I had a whole points manufacturing system in place.

Suggestion: AVOID LIKE THE PLAGUE.I never received my order, no eta, and the only response I received was dated 10/21 saying they’d contact the manufacturer for a status.

You probably aren't getting many people to even view it on the MLS, if buyers haven't checked to box to include manufactured homes in the search. 

I just asked a title rep in the area and she says they wont handle a close even as a transaction coordinator unless they write a policy for it which they cant do on a manufactured home on a rented lot.

If I were to apply for a CFO role now, more than likely I have to advantage over a CFO that was in a manufacturing company for a real estate company.EAs specializes specifically in taxationCPAs have a broader knowledge for accounting, auditing, financial planning, and taxation.EA must pass a 3-part IRS exam and do not require a college degreeCPA need a degree in accounting, 150 credit hours of education, must a 4-part CPA exam.EAs often charge a lower fees

A little further from home you'll find some of the value you are looking for in Kentucky, another state that is supportive of manufacturing and in following the state Economic Development you'll see chomping at the bit for more manufacturing. 

Here’s the context:I own a rural property with two rental units:A manufactured home from the 1980s in temporary status with the county (meaning it can’t be replaced), which currently rents for $1,350 per month.A one-bedroom permanent residence that rents for $1,300 per month.My monthly mortgage payment is approximately $1,200, and cash flow is crucial to me right now.

But to mandate or regulate how a auto manufacturer sells there goods is insanity, at best, and I'd argue quazi-communist at worst. 

What I see manufactured for sale is more a promise than reality.
