(b) A note executed by a purchaser under Subsection (a) must be secured by a vendor's lien retained in the deed and in the note on the property sold, and be additionally secured by a deed of trust on the property sold, with the usual provisions for foreclosure and sale on failure to make the payments provided in the deed and the note. (c) At the election of the holder of a note executed by a purchaser under Subsection (a), default in the payment of principal or interest or any part of the payment when due matures the entire debt.
