Federal legislation passed in 1974 to ensure that the various financial institutions and other firms engaged in the extension of credit exercise their responsibility to make credit available with fairness and impartiality, and without discrimination on the basis of race, color, religion, national origin, sex or marital status, age, receipt of income from public assistance programs (food stamps, social security), and to ensure good-faith exercise of any right under the Consumer Credit Protection Act (creditor must state reasons for denial of credit). The act applies to all who regularly extend or arrange for the extension of credit. A real estate licensee is considered a creditor if the licensee routinely assists sellers in determining whether a proposed buyer in a land contract or purchase-money mortgage is creditworthy.
