Divergent housing price trajectories in U.S. metropolitan areas
A Substack post by Pete Saunders highlighted a groundbreaking study by Lyons, Shertzer, Gray, and Agorastos that traces housing prices in 30 metropolitan areas across the USA from 1890 to 2006, using over 2.7 million classified ads. [1} The data reveal a profound divergence in urban housing markets, particularly between Midwestern and coastal cities.
Nationally, real housing prices remained mostly flat from 1890 to 1940, with homeownership functioning more as a stable commodity than an appreciating asset. However, post-1970—especially between 1997 and 2006—real capital gains in housing became significant, transforming homes into speculative investments in many regions.
The study documents a dramatic rise in housing prices in West Coast and Sun Belt cities (e.g., Los Angeles, San Francisco, San Diego), in contrast to Midwestern cities (e.g., Detroit, Cleveland, Pittsburgh). For instance, Detroit ranked first in housing prices in 1940 but fell to 26th by 1980, while Los Angeles rose from 25th to second.
A key observation from Saunders is that affordability in the Midwest stems not only from economic stagnation but also from an oversupply of suburban housing built during decades of population decline. Post-WWII suburban expansion continued even as central cities lost residents, leading to devalued urban housing stock and a bifurcated metro housing market.
