Ala. Code § 40-5-19 — Sale of Real Property If Personalty Insufficient

(a) When no personal property can be found out of which the taxes of any delinquent taxpayer can be collected, or an amount insufficient to fully satisfy the taxes, the real estate of the delinquent taxpayer or the real estate upon which the delinquent taxpayer’s taxes are a lien shall be sold for the payment of the taxes, or of the balance due thereon, as provided in this chapter.
(b) Notwithstanding subsection (a), the failure of the tax collecting official to exhaust the personal property of the delinquent taxpayer does not invalidate the sale of any real estate.
