This paper shows that house price fluctuations can have a significant impact on credit availability. Data from, a peer-to-peer lending site that matches borrowers and lenders to provide unsecured consumer loans, indicate that homeowners in states with declining house prices experience higher interest rates, greater credit rationing, and faster delinquency. We find especially large effects for subprime borrowers whose balance sheets are likely most exposed to asset price declines. This evidence suggests that asset price fluctuations can play an important role in determining credit conditions and are thus a potentially significant mechanism for propagating macroeconomic shocks.
