We show that following the legalization of same-sex marriage across US states, mortgage applications from same-sex borrowers are more likely to be denied relative to a matched sample of different-sex borrowers. Our findings are robust to using a stacked regression design and several approaches to account for compositional changes in the pool of mortgage applicants around same-sex legalization. FinTech lenders, which rely less on human loan officers, experience no change in the denial gap. Our results highlight information frictions between loan officers and same-sex borrowers as one channel for the increased denial gap between same-sex and different-sex applications.

We show that lenders charge higher interest rates for mortgages on properties exposed to a greater risk of sea level rise (SLR). This SLR premium is not evident in short-term loans and is not related to borrowers’ short-term realized default or creditworthiness. Further, the SLR premium is smaller when the consequences of climate change are less salient and in areas with more climate change deniers. Overall, our results suggest that mortgage lenders view the risk of SLR as a long-term risk and that attention and beliefs are potential barriers through which SLR risk is priced in residential mortgage markets.
