@David Cherkowsky reach back out to us, we can help you make these decisions! 

Moving forward in my  commercial leases I will now include language making the placement of thermostats the landlords decision with additional language prohibiting the relocation. 

Cashflow, ability to build a team, landlord tenant laws, price to rent ratio etc.......were all factors in the decision making process almost a decade ago.Now,  I wonder why your approach is an either or view? 

Option 1 - NOI = Rent - (maintenance, vacancy, management, property tax, insurance)or Option 2NOI = Rent - (property tax, insurance)in both cases i assume DSCR = monthly payment/NOI

The problem is that they are not knowledgable enough to understand that the analysis is inaccurate, but start making investment decisions based on the analysis anyway.That is one of the main problems I wanted to solve with DealCheck by providing a tool that takes most of the guess work out of running analysis calculations and evaluating rentals/flips/wholesale deals that will satisfy 80%+ of investors out there.But going further, I think that tools like DealCheck are perfectly viable even for more experienced investors.

They each have different stories about what is going on that are pretty different - how do I find out what is really going on in order to make this decision?

Quote from @Shakthi Kamal: If you don't know the answer, choose the umbrella insurance.

First, Are you licensed and insured to manage other people's properties?

I look for cashflow to service the debt, repairs, cap ex, taxes, and insurance while the equity grows, my taxes are decreased, and rents are increased to make more cashflow. 

You will have to gather more accurate operating costs (vacancy loss, taxes, utilities, insurance, mgmt fees, maintenance, HOA) to best determine potential future performance.
