Agricultural Valuation (Ag Exemption) in Martin County
Martin County has 2,497 parcels carrying a 1-d-1 agricultural valuation in our data. An ag valuation can cut a property’s taxable value sharply — but it does not transfer to a new owner automatically, and if the land’s use changes, Texas can recapture up to three years of the tax savings plus interest (the “rollback” tax, Tax Code §23.55). Confirm the current ag status and any rollback exposure on a specific tract before you buy.

Oil & Gas Activity in Martin County
Martin County has 17,128 oil & gas wells on record with the Railroad Commission of Texas — among the most active oil-and-gas counties in Texas (#6 of 254 counties). That much drilling history usually means an established mineral estate, active operators, and the surface activity that comes with it. If mineral rights matter to your purchase, research the severed mineral estate on any specific tract.
Counts are approximate, drawn from public RRC records, and include active and plugged wells. Not a substitute for a title or mineral search.
