The previous Landlord created the problem, you accepted it, and now it's going to cost you thousands to clean it up.I hope you got this property for a good price.

There's no real 'fair' way to truly separately meter the natural gas used for the different units, unless you get into rabbit hole land of re-inventing a wheel and a series of sensors measuring heat and air flow within separate ducts, on your (customer) side.I'll comment on each option individually and your decision will be numbers driven. 

Most of all, I want the freedom of creating my own destiny a la "Rich Dad". 

Create your own listings. 

(interior at hot water heater)$55 + 57 for the meter(S) and 900 for the 3g data logger, which is 20-30 per months for 3g service. 150 setup fee for customer billing management and a kick back from the tenant of 5-10 for convenience fees.

You have to create the cash flow instead of buy the cash flow.

I don't want to have 2 separate loans on each park under 1 entity because it just seems messy especially when filing taxes..So my question is would it make sense to create a new entity to own the park that I am refinancing and keep my existing entity with the park I am keeping with existing loan?

Kind of interesting looking at a larger scope of properties.For those not aware, MRIS, the MLS system in DC/MD/VA, which was already the largest MLS in the country, combined with about 10 other MLS systems to create an even larger MLS system.
