Using the confidential Home Mortgage Disclosure Act (HMDA) data from 2018 to 2020, we document the distribution of interest rates on mortgage loans charged to Native American borrowers located inside and outside of Indian country. The largest difference in interest rates between Native borrowers located in Indian country and non-Hispanic Whites is at the top of the interest rate distribution. Observed borrower characteristics, such as credit score and amount paid in discount points and fees, explain little of the premium charged to Native borrowers in Indian country. Rather, the higher mortgage rates are almost entirely attributable to the disproportionate use of chattel loans. A borrower's property interest cannot fully explain why many Native borrowers living in Indian country obtain chattel loans, and, as a result, face higher interest rates on mortgages.
