Irion County, TX Property Records
Irion County is on the Edwards Plateau in West Texas, adjacent to Tom Green County and the city of San Angelo. Its population is approximately 1,409 (2024), declining from 1,599 at the 2020 U.S. Census. The county seat and only incorporated city is Mertzon, with a population of approximately 800. The county was created in 1889 and organized in 1936. It is named for Robert Anderson Irion, who served as Secretary of State of the Republic of Texas.
The economy is based on ranching, oil and gas production, and proximity to San Angelo. The Concho River area ranch market generates significant land transaction activity. The median household income is approximately $70,357, and median home values in the county are approximately $140,000–$200,000 (estimated, reflecting the thin market and ranch land influence).

How to Access Irion County Property Records
You can access Irion County property records online, in person, by phone, and by mail. The process depends on the type of record you need.
Online Access (Free)
Irion County property records are available online through TexasFile, a statewide records portal. Select Irion County from the county list and search by grantor or grantee name, instrument number, document type, or recording date. Most deed, deed of trust, release, and lien instruments recorded in recent decades are indexed and available as scanned images.
Property ownership, valuation, and exemption data are available through the Irion County Appraisal District. The portal allows searches by owner name, property address, and legal description. This is the appropriate resource for assessed values, exemption status, and current ownership; it does not replace the County Clerk's deed records for title research.
In Person
While online portals are often the most convenient option, you can visit the relevant offices directly for certified copies, recording, or research assistance:
The Irion County Clerk remains open through lunch Monday–Thursday, a departure from many rural county offices.

Named for a Republic of Texas Secretary of State: Robert Anderson Irion served as Secretary of State of the Republic of Texas from 1837 to 1838. He was also the brother-in-law of Sam Houston.
Adjacent to San Angelo and Tom Green County: Mertzon is 26 miles southwest of San Angelo. Properties in western Irion County are subject to San Angelo-area market influences, lending relationships, and title company coverage. Some Tom Green County institutions serve Irion County buyers and sellers.
Texas uses a County Clerk, not a Recorder of Deeds: The County Clerk is the statutory custodian of all recorded land instruments under the Texas Local Government Code.
Texas uses deeds of trust, not traditional mortgages: Search for "deed of trust" rather than "mortgage" when examining encumbrances.
Severed mineral estates are common: A deed to the surface does not convey mineral rights unless explicitly stated. Mineral ownership must be traced through a separate chain of instruments.
Texas homestead rights: Both spouses must sign a deed or deed of trust to convey or encumber the homestead.
Community property state: Property acquired during marriage is generally owned equally by both spouses.
Agricultural land exemptions: Land qualifying for ag appraisal is valued on productive capacity rather than market value. Assessed values may be substantially lower than market value.
