I would pass on a retail (priced) deal, you're overleveraged in terms of your time and energy to new projects.

Here's the 4th quarter economic report for Huntsville.

It's likely best to use that energy to find another deal. 

The small amount of energy used by running the fan when it is not needed is a small price to pay to avoid having a mold issue.  

Surely there is someone out there doing this in a more economical mode...?

I rather put my energy elsewhere like updating the yard etc.

I’m looking for clients and want to know where to put my energy

Don't forget about occupancy inspections, that's $100 per unit pretty much every year you have a turnover.Like Austin also mentioned, what is physical vs. economic occupancy? 

I spent more emotional energy and time on my first 4 units every month than I now do on 65+ units in an entire year and I self-manage!

I know there are incentives or rebates through focus on energy, but with that program we cannot replace any of our heaters since they do not have incentives for electric base boards heaters and you need to replace your heating source with the same heating technology.
