Bricks and behavior: The repair and maintenance costs of housing for persons with mental illness

Comprehensive data on 153 properties offering independent living for persons with mental illness are used to examine the effects on repair and maintenance (RM) costs of building quality, neighborhood quality, building size, proportion of tenants with mental illness, and management experience with mentally ill tenants. We find an inverted U-shaped relationship between the proportion of mentally ill tenants in a building and its RM costs, which suggests favorable behavioral effects on mentally ill tenants of living in the same building with others who are mentally ill. We also find amenity features are associated with higher RM costs in properties where more tenants are mentally ill.
