How much time and energy do you want to devote to it to save the 8-10% of your rental income. 

Let's hope the stars align! 

The Sense Home Energy Monitor is one that connects to each circuit in you main panel so you can tell how many KWh each one is using.

I know this doesn't answer your question, but I'd spend that time and energy finding another deal for myself rather than making the one I have more complicated.  

Thank you that’s what I thought just wanted to make sure before I start spending time energy and money on the process.   

Juice me up and I'm off to the stars...I'm not a sucker, I'M A WINNER!!!"

Did it help you to learn what you were good at and you stuck with that, or were you able to see what worked and what didn't so you could focus your energy on the winning strategy. 

Tough to answers these without knowing a little more.If you don't have the time, energy, or interest in searching for properties on your own, don't want to find your own lenders, attorney, inspector, etc on your own, don't feel comfortable negotiating for yourself, and want someone experienced who has a fiduciary duty to you representing you, then I recommend using a realtor (says the realtor). 

I don’t even think about STR as a strategy here in Boulder anymore, it can still be done but the regulations to comply with (STR license and associated annual fees, taxes, SmartRegs (energy efficiency standards) compliance, must be owner-occupied (even if it’s a duplex you have to occupy the side being rented short term), limits on number of nights it can be rented per year, limits on number of STRs in proximity of each other in a neighborhood, annual inspections, etc.) make it not even worth doing here basically IMO I’d rather just do corporate rentals with 30 day minimum stays or regular term rentals.

They create a tighter building envelope, and allow for a energy efficient home.
