Article Abstract:
A multinomial logit model is developed to aid in determining the causes of default of insured home mortgages. Interest rate risk has been shifted to depository institutions from the borrower. Data from the Mortgage Guaranty Insurance Corporation from 1960 through 1980 show the principle causes of default and prepayment. Default is linked to original loan/value ratios and unemployment.
