I remodeled a 4 plex with LVP and had one bad tenant put a scratch in the floor after 2 months but the other 4 tenants have had zero problems after the remaining 10 months.

That would be akin to selling your stocks in 2012 after losing your butt for 5 years; which was 5 years shy of the FULL rebound of the stock market to a point about 2x the 2007 highs.Investing in the stock market is not wisely used a short-term investment vehicle and I believe you would be doing yourself a disservice to look up and see the sky falling (due to a very clear cause -- a virus) and dump your depressed stocks so that you could put that money into a (potentially) inflated commodity like investment real estate.   

The market has remained extremely competitive in some areas.

Ironically, this town removed their last remaining pay phone a decade ago...Is this also normal in anyone's experience??

If you have enough tucked away to live 40-50 years on your anticipated budget considering inflation then I don't think there's anything wrong paying down your mortgage early for peace of mind.Assuming that you are going to remain in the home you are talking about, paying down principal has terrible opportunity costs if you assume even a modest return on the savings.

I am currently looking at new construction SFR as an investment north of Seattle area, in a development with one remaining home where framing has just been completed, electrical work to begin soon. 

With the remaining Profit from the Sale of the Commercial property and the Equity Line of Credit and the Tax-free profit from Sale of my Residence I will have enough to "farm" the area where I am moving to and never spend all the money.

Also, I like some of the first tier suburbs where you can still buy some value and prices aren't inflated like other areas.2.

They are making sure they have strong, consistent cash flow today, and with modest rent increases over time, will be able to outpace inflation. 

I could see property values down or up 15% within the next 12 months. 5-10 yrs I remain bullish on All of the Bay area counties due to fundamental lack of supply.
