(d) Assignment of mortgages authorized by section 203(q), National Housing Act. Notwithstanding the provisions of paragraph (a) of this section, the Secretary will, upon application by the mortgagee, agree to accept assignment of any mortgage authorized by section 203(q) of the National Housing Act (§ 203.43j of this part) if
(3) The date of default occurs before the mortgagor and the lessor execute a lease renewal or a new lease with a term of not less than five years beyond the maturity date of the mortgage, or with a term established by an arbitration award.
If the default is non-monetary, the date of default occurs prior to an action described in paragraph (d)(3) of this section, the requirements of § 203.666 are satisfied, and the mortgagor has been in default for more than 30 days, the Secretary may in his or her discretion, upon application by the mortgagee, agree to accept an assignment of the mortgage. If the leasehold estate has terminated before the mortgage has been assigned, or title to the property conveyed, to the Secretary, and the mortgage is in default for any reason for more than 30 days, the Secretary will, upon application by the mortgagee, agree to accept an assignment of the mortgage.
(e) Filing assignment for record. Within 30 days of the Secretary's written agreement to accept assignment of a defaulted mortgage, or within such additional time as the Secretary authorizes in writing, the mortgagee must file the assignment for record.
