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). 

This is my 1st post and I am so incredibly thankful that a forum like this exists and for any information to help guide me through this tough decision is so immensely appreciated! 

Perhaps they would make more money if STR was an option, however if that's not permitted in their location, no STR demand exists, or no STR PM is willing to take on their property, they may not have that option.

But those basically don't exist anymore.

That way they're not soliciting you w/o a pre-existing relationship, and you still get to look at their work. 

near 0% and 0% options with DPA's exist (down payment assistance) programs.

You want to know the total demand and the existing competition.  

They exist for a reason.

We try to keep good tenants for long term, an dhave several 30 year tenants and a 24 year tenant and average 12.5 years over the portfolio of existing properties.

These 6 items all can require a significant cost to remedy so it's important to be able to identify the existing condition.
