Title risk

Liens that survive the sale

Tax sale certificate is a lien; investor must petition for tax deed after statutory period (~3 years per county FAQ). Federal liens and certain interests can survive. IL equity/surplus issues after federal court rulings remain an underwriting risk.

Quiet title

Tax deed petition process is required to obtain title; insurers often want additional quiet-title or curative review before insuring for resale/refinance.
