In your link to Department Of Numbers, it shows asking prices up 0.9% month-on-month.
Meanwhile, Redfin’s graph at the bottom right of this page shows an 8% increase month-on-month in asking prices.
Both are for San Diego, so it should be an apples to apples comparison. So how can two reputable sources come to such hugely different conclusions. (A 0.9% m-o-m increase is a normal market. An 8% m-o-m increase is a boom. Very different animals).
I don’t know enough to know which one is right. Anecdotally, I don’t see a slow-down.
