I'm new to taking action with REI and am willing to step forward, fail, learn from failure, and progress that much faster.Edit: Also, if anyone has any recommendations to make the deal analysis more efficient, I'm all ears.

You're waiting on your water to be refilled, as your cup is sitting there empty.

They require additional insulation, only tankless water heaters, only mini-split HVAC, Etc, Etc.

Many local gov't will require a feasibility study, environmental surveys, storm water run off reports, etc... it varies from county to county, state to state, but be aware. 

It's cheaper, more efficient, and leaves a smaller footprint.

I've seen the bad side (although that was 2010-12 or so, so I am old and biased) when inspections was a PITA and at least once cost me more in collective 'inspections fees' than the water tank replacement. 

What is the most efficient way to collect rent?

Unless it's different in Oklahoma, typically, the landlord pays for the water on a duplex, so keep that in mind.I hope this helps and good luck.

We wiped with disinfectant & water but not sure if this was the best way.
