That’s a good question and one everyone should be asking of themselves occasionally.
I am heavily into real estate in a weak area economically, but have done OK mainly because of the low interest rate environment. Have regularly refinanced into lower interest rate loans over the past 6 years. So cash flow is good because interest costs have been cut in half. Appreciation in values, not so good.
I am not at all into the stock market and wish I had been, since it is 2 1/2 times its low of about six years ago. Now it is so overvalued that I cannot imagine jumping in, which is exactly what I have thought for each of the past few years as it has gone up.
