“Real Estate Prices never go down” is sort of like saying “The Chargers are good this season, so they will be good forever”.
Of course real estate prices are actually more predictable than football teams. I’m a Vikings fan, and I don’t know how many years in the past 5-10 where we’ve looked really strong coming into the season and ended up pitifully mediocre. At least the Chargers tend to be boom or bust.
