About Duval County land
Duval County sits in the heart of the South Texas Brush Country, with San Diego as its county seat and Freer a key hunting and oilfield town. Freer is about 125 miles south of San Antonio and 80-some miles west of Corpus Christi, putting the markets within a 2–3-hour drive. The terrain is nearly level to undulating (250–800 feet), dominated by mesquite, brush, and prickly pear.
The climate is semi-arid (about 24 inches of rain), with water drawn largely from the Gulf Coast Aquifer plus stock tanks. The county is legendary for hunting — the South Texas Plains are known for mature whitetail bucks and above-average antler quality, alongside bobwhite quail, dove, javelina, hog, and nilgai. Roots run through cattle ranching, a historic oil boom, and a deep deer- and quail-hunting culture — home of Freer's renowned Muy Grande Deer Contest.
What to know before buying in Duval County
Owner financing, no bank
We finance Duval County tracts directly — a down payment and monthly payments to us, with no bank qualification. Down payment, rate, and term are set per tract, so ask for current figures.
Surveyed, with deeded access
Every tract is surveyed with deeded access on graded ranch roads, so boundaries and entry are settled before you buy.
Light restrictions
Sensible restrictions protect value while keeping recreational, hunting, and homestead use open — no heavy HOA-style rules.
Ag & wildlife tax valuation
Much rural land here carries an agricultural or wildlife-management property-tax valuation that keeps annual taxes low. Confirm the current use and exemptions for any tract with the county appraisal district.

Ag valuation (1-d-1 open space)
Land in agricultural use for five of the last seven years can be appraised on its productivity value instead of market value, which is what keeps rural taxes low. The use has to be the land's primary use, to the degree of intensity typical for the county. You apply once with the appraisal district (state form 50-129) and it stays until the use changes.
Wildlife management
A tract already under ag valuation can switch to wildlife-management use and keep the same low valuation by managing for native wildlife: habitat control, supplemental water or food, predator control, census counts, with a written plan on the state form. Popular with hunters who don't run cattle. The minimum acreage after a subdivision is set county by county.
Rollback tax
Taking ag-valued land out of agricultural use triggers a rollback: the difference between taxes paid on productivity value and taxes on market value for the previous three years, plus interest. Building a home on part of a tract does not by itself end the ag use on the rest.
Protest deadline
The appraisal district mails notices of appraised value in spring. A protest to the Appraisal Review Board is due by May 15 or 30 days after the notice is delivered, whichever is later.
When taxes are due
Bills go out in October and are due by January 31 of the next year; penalty and interest start February 1. Our tracts are surveyed and platted, so each tract gets its own account and its own bill once the deed is on record.
Homestead on a rural tract
If you build and live on the tract as your principal residence you can claim the residence homestead exemption on the home and up to 20 acres; the rest of the tract can stay under ag or wildlife valuation.
Tax rates, appraised values and minimum acreages change every year; confirm current figures for any tract with the county appraisal district.
