There are a lot of great spiritual resources out there or therapy to help people address these negative thoughts that can at its worse, ruin someone's spirit and zest for life.Her insecurities and jealousy and her emotions that is on her to work on at the end of the day as well.

Otherwise I recommend you make a schedule and stick to it religiously, while doing your best to unplug, take time away from real estate altogether and pick it back up the next day. As

I've had HVAC fail on move-in day, a furnace go bad on the first cold day of the year, things like that.

Just doesn’t happen every day as @Joe Schmitt can attest.  

If I was a renter I'd take a video of the property on move out day to show its condition - it's also a good idea to do the same on move-in day as well.

We may rotate the day, as well as the time of the meeting to better accommodate the fact that people have varying availability. 

But at the end of the day, as long as you keep paying the mortgage, they won't care much. 

One day a surge of supply may happen.  

One thing to remember is what cost x amount 5 - 10 years ago isn't going to be the same amount.I would say reviewing your insurance and your property values on a yearly basis is extremely important especially if you don't insure them for replacement cost.At the time of a loss it would be very frustrating for an investor to not have the purchasing power for a similar property in present day as they did 5 years ago due to the value of real estate increasing in the location. 

But it's only been on the market for a day as of today, and my understanding is that Memphis is a pretty hot market right now.I see your refi loan amount is $56k, or 80% of the ARV.
