N.M. Stat. § 58-10-40
Any association may pay taxes, assessments, supplemental abstract or title search charges, insurance premiums and other similar charges for the protection of its interests in properties securing its real estate loans, which advances may be carried on its books as an asset of the association and for which it may charge and collect interest, or the advances may be added to the unpaid balance of the loan as of the first day of the month in which the advances are made. All such advances constitute a valid lien against the real estate securing the loan for which they were made. An association may require borrowers to pay monthly, in advance, in addition to interest or interest and principal, the equivalent of one-twelfth of the estimated annual taxes, assessments, insurance premiums and other charges upon the real estate securing any loan, or any of these charges, so as to enable the association to pay them as they become due from the funds so received. The amount of the monthly charges may be increased or decreased as necessary for their payment. An association may carry such funds in trust in an account or may credit them to the indebtedness and advance the money for taxes, insurance and other charges as they come due. Every association shall keep a record of the payment by the association of taxes, assessments and insurance premiums on all real estate securing its loans and on all real and personal property owned by it.
