Unless the Fed is going to start buying millions of homes outright, prices are going to fall to what buyers can afford.
There are two generalities that can be applied to all asset bubbles:
1. Bubbles inflate for longer and reach higher levels than most pre-bubble analysts expected
2. All bubbles burst, despite mantra-like claims that "this time it's different"
The bubble burst tends to follow a symmetrical reversal of very similar time durations and magnitudes as the initial rise. If the bubble took four years to inflate and rose by X, the retrace tends to take about the same length of time and tends to retrace much or all of X.
If we look at the chart of the Case-Shiller Housing Index below, this symmetry is visible in Housing Bubble #1 which skyrocketed from 2003-2007 and burst from 2008-2012.
Housing Bubble #1 wasn't allowed to fully retrace the bubble, as the Federal Reserve lowered interest rates to near-zero in 2009 and bought $1+ trillion in sketchy mortgage-backed securities (MBS), essentially turning America's mortgage market into a branch of the central bank and federal agency guarantors of mortgages (Fannie and Freddie, VA, FHA).
These unprecedented measures stopped the bubble decline by instantly making millions of people who previously could not qualify for a privately originated mortgage qualified buyers. This vast expansion of the pool of buyers (expanded by a flood of buyers from China and other hot-money locales) drove sales and prices higher for six years (2012-2018).
As noted on the chart below, this suggests the bubble burst will likely run from 2019-2025, give or take a few quarters.
The question is: what's the likely magnitude of the decline? Scenario 1 (blue line) is a symmetrical repeat of...
