Caddo Mills, Texas
Caddo Mills is a city in Hunt County at the western edge of Northeast Texas, about 26 miles east of McKinney. It sits in the rolling farmland and prairie of the region, a rural community that has begun to feel the outward growth of the Dallas–Fort Worth metroplex to its west. The city operates the Caddo Mills Municipal Airport, a general-aviation field serving the surrounding area.
Property here runs through the Hunt 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 Hunt County notes below cover the practical details, with the official county directory for the appraisal district and tax office.

What to know around Caddo Mills
Property Tax Basics
Two offices handle your property tax bill
The Hunt County Appraisal District sets your property value; the Hunt County Tax Office sends the bill and collects payment. They are separate offices.
Homestead Exemption
Homestead exemption lowers your taxable value
If Hunt County is your primary residence, a homestead exemption reduces the taxable value on your property tax bill.
OSSF / Septic
Septic systems outside city limits need a permit
A new or replaced septic system in rural Hunt County starts with the Health Department's OSSF permit process.
Private Wells
Private water wells follow state rules in Hunt County
Rural land in Hunt County may rely on a private well, and TWDB records put the county outside a local groundwater district.
Flood Risk
The Sabine River and its forks flood parts of Hunt County
Most of Hunt County drains into the Sabine River basin, and bottomlands along those waterways carry flood risk that FEMA maps track.
Vehicle Registration
Many Hunt County car renewals are simpler now
Most Hunt County cars and light trucks no longer need a safety inspection before renewal. The tax office still handles in-person renewal.
