How do sustained higher mortgage rates affect home sales and construction?
Core argument: Existing home sales are forecast at 3.8mn in 2024, the fewest annual sales since the early 1990s, as nearly all mortgage borrowers hold rates below current market rates, disincentivizing moving.
Sustained higher mortgage rates will have their most pronounced impact in 2024 on housing turnover. Nearly all mortgage borrowers have interest rates below current market rates, strongly disincentivizing them from moving. As a result, we expect the fewest annual existing home sales since the early 1990s at 3.8mn. Limited available housing supply has kept homebuilding resilient to higher interest rates: despite 3½pp higher mortgage rates today, housing starts were 5% above 2019 levels in September. While vacancy rates remain at historic lows, we expect housing starts to decline by 4% to 1.34mn in 2024, reflecting sharply fewer multifamily starts.
