According to a recent study, requiring down payments of at least ten percent is less likely to prevent a mortgage from defaulting than other measures, such as requiring borrower income documentation and prohibiting hybrid adjustable-rate mortgages with “teaser payments”.
Researchers at the University of North Carolina’s Center for Responsible Lending used national level data to examine the effect of various requirements on borrowers’ access to mortgage credit and on the number of defaults they would be likely to prevent.
