Mertens, Texas
Mertens is a small town in Hill County, in the blackland prairie country of North Central Texas, about 38 miles northeast of Waco and a similar distance south of the Dallas-Fort Worth suburbs. It sits amid gently rolling farmland long worked for cotton and grain. The community is a quiet rural settlement of the sort scattered across the region's farming country.
Property here runs through the Hill Central Appraisal District and the county tax office — the homestead exemption, the appraisal cap, protests, and any MUD, PID, or special districts all sit at the parcel level. The Hill County notes below cover the practical details, with the official county directory for the appraisal district and tax office.
