ZIP codes with high concentrations of originators who misreported mortgage information experienced a 75% larger relative increase in house prices from 2003 to 2006 and a 90% larger relative decrease from 2007 to 2012 compared to other ZIP codes. Several causality tests show that high fractions of dubious originators in a ZIP code lead to large price distortions. Originators with high misreporting gave credit to borrowers with high ex-ante risk, yet further understated the borrowers' true risk. Overall, excess credit facilitated through dubious origination practices explain much of the regional variation in house prices over a decade.
