(5) The authority shall require as a condition of each loan to a lending institution that such lending institution, within such period after receipt of the loan proceeds as the authority may prescribe by regulation, shall have entered into written commitments to make and, within such period thereafter as the authority may prescribe by regulation, shall have disbursed the net loan proceeds in mortgage loans on residential housing in an aggregate principal amount equal to the net amount of such loan proceeds. Such mortgage loans shall have such terms and conditions as the authority may prescribe;

(6) The authority shall require each lending institution to which the authority has made a loan to submit evidence satisfactory to the authority of the making of new mortgage loans for residential housing as required by this Code section and in connection therewith may, through its employees or agents, inspect the books and records of any such lending institution;

(7) Compliance by any lending institution with the terms of its agreement with or undertaking to the authority with respect to the making of mortgage loans for residential housing may be enforced by the decree of any court of competent jurisdiction;
