It may be, depending on the "date" you are measuring against. Like they say, it ain't over till the fat lady sings

An example.
We purchased our last home in 1979. By the mid-80's, we were (in today's term) almost "underwater", but not by much since we put 20% down - which was the minimum for a conventional note/mortgage in those days.
When we sold it in 2004, 15 years later it was for twice the price of our orignial purchase price. Long term? It worked out well.
In 2004, we had our current (retirement) home built. Over the go-go years, it had increased in "perceived value" greatly.
Today? It is "worth" less than it was during the good times. However (and for us, the most important), it is still valued at 50% more than the build price.
It's a bit like a buy/hold investor (which I/DW are). What happens today, or even for a few years, means little. What does it mean in the long term?
