Each year, the Texas Chapter of the American Society of Farm Managers and Rural Appraisers publishes a Rural Land Value Trends report. They just released their 2021 edition. Access this website to download: < https://www.txasfmra.com/rural-landtrends>.
This report breaks Texas into seven regions and then each region is broken into smaller sub-regions. The report then offers information regarding land prices and leasing rates for various types of property from irrigated cropland to rangeland to CRP land. Additionally, this is the only publication I am aware of that publishes average hunting lease rates for the Lone Star State.
Here is an example of the data collected for each sub-region. This information is for the Northern Panhandle and South Plains sub-regions.
