Tenn. Code Ann. § 66-30-104: Lien against real estate

A residential ground rent shall constitute a lien against the real estate from the time it is recorded, in a like manner as would a deed of trust or mortgage. Any deed of trust or mortgage on the interest of the obligor in the real estate may provide that a default in payment of ground rent shall constitute a material default in such deed of trust or mortgage; that the trustee or beneficiary thereunder may satisfy such obligation for rent, and that the money so advanced, with interest thereon, shall be a part of the debt secured, to be repaid as provided by law, and such trustee or beneficiary shall be subrogated to the rights of the obligee in the real estate to the extent of such advancement and interest.
