Home Mortgage Disclosure Adjustment Act This bill amends the Home Mortgage Disclosure Act of 1975 to exempt a depository institution from certain records and disclosure requirements related to the itemization of loan data: (1) with respect to closed-end mortgage loans, if the depository institution originated fewer than 500 such loans in each of the two preceding years; and (2) with respect to open-end lines of credit, if the depository institution originated fewer than 500 such lines of credit in each of the two preceding years.
