Notes

Missouri collector tax sale: parcels with three or more years of delinquent real estate taxes are offered beginning the fourth Monday in August (2026: August 24). St. Louis County runs a sealed-bid process (not live open outcry) for certificates of purchase — you buy a tax lien certificate, not immediate fee title. First/second/third offering structure applies under RSMo Ch. 140; post-third offerings can later be purchased under separate rules. Nonresidents must appoint a Missouri agent. Notarized bidder registration + photo ID required; $27 recording fee added per parcel at sale. City of St. Louis (independent city, FIPS 29510) runs a separate Sheriff land-tax sale program — do not confuse the two.

Title risk

Liens that survive the sale

First- and second-offering sales generally leave many private liens in place (certificate of purchase). Third-offering/post-third processes can strengthen the path to a collector's deed after statutory notice and waiting periods. Federal tax liens and some municipal charges can survive. Full title search mandatory.

Quiet title

After redemption expires and deed issues, quiet title is commonly used to obtain insurable title on Missouri tax-sale property.
