Here's a strategy.
Use leverage. For a time your Portfolio of investments and real estate equity is down.
If you get mortgage loan forebearance (or refi-cash out), use that money, to buy more stock at current lower prices.
Anybody that sold real estate and investments following the 2008-2009 crash, missed the increase when they returned to well above their prevvious highs.
That presumes of course you don't panic. That retirement is awhile in the future, or you are already financially stable.
Think long term. Warren Buffett didn't trade short term. He bought (and held) long term.
Have faith in America. Have faith in our economy & investing.
