Sachse, Texas
Sachse is a suburban city on the northeastern edge of the Dallas-Fort Worth metroplex, straddling the line between Collin and Dallas counties just beyond Garland and Plano. Once a small cotton-farming settlement on the North Texas blackland prairie, it grew into a residential community as the metroplex expanded outward. The town carries the name of William Sachse, an early landowner whose gift of railroad frontage in the 1880s fixed the town's location and name.

Sachse crosses county lines, so the appraisal district and tax office depend on the parcel address. School, city-limit, MUD, PID, and other special-district lines can be different too. Start with the full county list below instead of treating one county as the answer.
