Key Takeaways
  • • Sharon Cornelissen, Director of Housing at the Consumer Federation of America, has coined the term "mortgage desert" to describe the 10% of U.S. counties where the smallest portion of homes are purchased using mortgages, creating barriers to homeownership and wealth accumulation for local residents.
  • • Mortgage deserts are not defined by absence of home sales activity; they emerge in areas where institutional real estate investors dominate cash purchases, low home values discourage lender participation, or small-dollar mortgage origination becomes economically unviable for financial institutions.
  • • The concentration of cash-based real estate transactions in these regions directly reduces local homeownership opportunities and diminishes wealth-building capacity within communities, according to research from the Consumer Federation of America.
  • • Mortgage deserts affect both rural and urban geographies, with disinvested neighborhoods and vacation towns particularly susceptible to the phenomenon, as documented in the new CFA research initiative.
Summary
The Consumer Federation of America has introduced "mortgage deserts" as a new analytical framework for understanding geographic disparities in mortgage lending and homeownership access. The term, coined by Sharon Cornelissen, Director of Housing at the CFA, identifies the 10% of counties where mortgages finance the smallest share of home purchases. This research designation reflects a critical gap in residential financing availability that extends beyond traditional lending desert definitions.

Mortgage deserts emerge through multiple mechanisms. In some regions, institutional real estate investors purchasing substantial volumes of properties with cash systematically reduce the relative prevalence of mortgage financing. In others, low home valuations diminish lender incentives to undertake the operational costs associated with originating mortgages, particularly smaller-dollar loans that offer limited revenue relative to underwriting expenses. The phenomenon is not synonymous with dormant housing markets; active home sales and transactions continue in these areas—the distinction lies in the financing methodology and its implications for individual homebuyers.

According to Cornelissen's analysis, the consequences of mortgage deserts extend beyond individual transaction mechanics. These geographic zones experience compressed homeownership opportunities and diminished local wealth accumulation, as mortgage-financed purchases traditionally represent a primary mechanism for building household equity and intergenerational wealth transfer. The research documents that mortgage deserts span both urban and rural jurisdictions, with particular concentration in disinvested neighborhoods and vacation town markets, indicating that the phenomenon crosses traditional geographic and demographic boundaries.

The identification of mortgage deserts carries significant implications for residential real estate market structure and community economic development, suggesting that cash-dominated transaction patterns in specific regions may perpetuate structural disadvantages in wealth creation and property access for local populations.
