And I usually presume (far from uniform) that the SFR neighborhoods (all things being equal) are better.  

You presumably don't live there so it doesn't affect your safety.

Don't count those cash flow chickens before they hatch ... you have now a property that you KNOW performs well, meaning it cash flows well, you can presumably manage it fairly easily, rents come in on time, etc. and you plan to sell and buy another property in a different market that you think MAY perform better ... you may be right on that or you may be wrong, but it is by no means a surefire bet.

Often times people are presumed to be wealthy because they live in a big house or drive a fancy car, but I would argue that alone usually doesn't tell you how well the person is really doing financially.

More education for those of you who do not understand medicine/science: the death rate is not inflated, many patients are being diagnosed with COVID-19 clinically, meaning they may not have been tested but are presumed to have the disease based on their clinical presentation.

Be open to pivot: So, I'm presuming that you're looking at SFRs in Nashville, so that train may have left and that is fine.
