U.S. Housing Market in 2021
2021 was the absolute speed peak of the U.S. housing market. Existing-home sales hit 6.12 million, the highest since 2006; median prices jumped 17.5% YoY to $357,100 — the largest single-year price increase on record; and 30-year mortgage rates bottomed at 2.96%, the lowest annual average in the 50-year PMMS history.
Three forces compounded. The Fed held rates near zero and continued $120B/month in MBS purchases through November. Pandemic savings remained elevated. Remote work permanently shifted housing-location preferences for an estimated 30M U.S. workers. By year-end, the median home cost 5.1× median household income — a stretch that would only intensify as 2022 brought 5%+ mortgage rates without commensurate price relief.
Macroeconomic Context
The U.S. economy rebounded explosively in 2021. GDP grew approximately 5.9 percent — the fastest calendar-year growth since 1984 — propelled by vaccination-enabled reopening, massive fiscal stimulus (the American Rescue Plan added another $1.9 trillion in March), and the release of pent-up consumer demand. Unemployment fell from 6.7 percent to 3.9 percent over the year. But the recovery's speed created problems: global supply chains buckled under simultaneous demand surges across every category of goods, and inflation that policymakers initially labeled "transitory" proved anything but.
Consumer price inflation reached 7.0 percent in December on a year-over-year basis — the highest reading since 1982. Supply chains for semiconductors, automobiles, lumber, and appliances were severely disrupted. Lumber prices tripled at their 2021 peak, adding $36,000 to the cost of an average new single-family home according to the National Association of Home Builders. The Federal Reserve kept rates near zero through the year, insisting that inflation would subside as supply chains normalized — a judgment that would prove costly and require dramatic correction in 2022.
Housing supply and demand were catastrophically mismatched. The combination of pandemic-driven demand, record-low mortgage rates that began the year at 2.65 percent, and years of underbuilding since the financial crisis left available inventory at all-time lows. Months' supply of existing homes fell below 2.0 months at points — half the level considered balanced. Median existing-home prices surged roughly 15 percent for the full year, the largest annual increase on record. Markets that had seemed sleepy — Boise, Idaho; Austin, Texas; Raleigh, North Carolina — saw bidding wars and cash offers above asking price become routine.
