There are individual markets where things are illogical. I know of one, for example, that has had an occupancy slump for years, but the values are starting to rise as outside investors look for a place to park money they pulled out of markets with an obvious unsustainable growth rate. There seems to be a logical disconnect with these investors.
The good news is, these markets are easy to spot. If you imagine the bastions of blue state thought, look at what markets in red states have similar people, and you avoid those markets, you'll be fine.

There are money which fly into U.S. away from political instability or economic troubles in other countries.
They usually get parked at big name cities like LA or NYC. If Chinese economy goes down, a few hundred billions of dollars could pour into U.S.. When Soviet Union collapsed, KGB funneled out $400 billion according to some reports. The same thing could happen to China on its way down. Overseas economic crises spread out over time could provide periodic injection of foreign cash into U.S. markets, especially real estate markets. They could work as a cushion which can buy time for U.S. economy.
This seems to be what is happening to U.S. Other economies fall down before U.S. does, helping U.S. economy with escaped money.
