This exploration combines and analyzes information from three sources to assess the potential effects the GSEs' underwriting and appraisal guidelines on the funding of loans on properties affordable to lower-income people and in underserved areas, and the impacts automated underwriting and credit scoring technology have on low- to moderate-income and minority borrowers. In addition, it includes information about lenders' perceptions about the effects of the GSEs' guidelines on minority mortgage applicants, since minorities' lower average incomes and wealth mean that underwriting guidelines are likely to disqualify higher proportions of minority applicants.
