A duplex that I bought in 1986 for $315k may have peaked in value at around $400k in 1990, then dropped back to around $300k by 1994. Right now, it would probably sell for $1400k (too bad I don't own it anymore!).
OK, that's a 367% increase from the 1994 low, but it's still a 250% increase from the 1990 high. Even in inflation-adjusted terms, that's still about a 100% increase.
At the 1990 peak, it would have sold for 16 times its annual rental potential. Today, that ratio is about 29.
IOW, things are way out of line with the prior peak.
Hard work often pays off over time,
but laziness always pays off right now.
