They will be looking for very nice, safe places to live and raise families with a nice vibe for young, healthy, active professional people. 

That doesn't mean they are "updated" but it's in everybody's interest to provide a safe and healthy environment for the tenant buyer.One property I bought in Mesa is a 4 bed 2 bath that I had my guy cleaning and on the second day of filling the dumpster, someone in the neighborhood was walking by, saw the house and two days later was putting $25,000 down and the first month's rent, he chased my guy out of there ;-) and he finished filling the dumpster himself.

People's mental health is going to start suffering.

Hope everyone is staying safe and healthy. 

If her health is so bad, why isn't she moving out immediately? 

:D  Costs you almost nothing, and will pay big dividends in the long run.Stay safe and healthy up there in Seattle (we were just there a few months ago).  

And I believe the demand in the Fresno area will always be healthy. 

What I’m worried about is if we will see some kind of multiplier effect here amongst the healthy sub 50 set.

The downside is that appreciation is less consistent and you could buy at a bad time, and may actually lose money if the market slides.This is why I would stay away from both extremes and aim for something that has a healthy cashflow (enough to at least break even with, after all expenses), and a good potential for future appreciation.

But, I want to be healthy and fit so I can enjoy such things for several decades.
