How Is Land Valued in Texas? CAD Appraisals vs. Market Value

If you own land in Texas, the value you see on your property tax bill may not be the same number a buyer would actually offer for it — and understanding why is genuinely useful before you sell.

Two different numbers, same parcel

Every Texas county appraisal district (CAD) tracks a market value for each parcel — its assessed worth based on land characteristics, location, and size. But if your land qualifies for an agricultural, wildlife, or open-space use exemption (often called a "1-d-1" exemption), the county taxes it based on a much lower agricultural productivity value instead of that market value. The market value is still recorded — it's just not what shows up on your tax bill.

Why the gap can be enormous

This isn't a small difference. On agricultural-exempt land, the taxable productivity value can run 90% or more below the recorded market value — a parcel with a market value in the millions might be taxed on an assessed value in the tens of thousands. That's by design: it's meant to keep property taxes affordable for working farms and ranches, not to represent what the land is actually worth on the open market.

Where to find your parcel's real market value

Every Texas CAD publishes a public property search tool. Searching your parcel by owner name, address, or account number typically shows both figures — often labeled "Market Value" and "Appraised Value" or "Ag Use Value." The market value, not the taxable one, is the more useful starting point for understanding what your land might be worth in a sale.

Why this matters when you're selling

• An offer based on the taxable value alone (instead of market value) would be dramatically lower than it should be — worth checking which figure any offer is actually anchored to.
• Texas is a non-disclosure state, meaning actual sale prices aren't public record anywhere — so the CAD's market value is often the most reliable public starting point available, even though it's not a guaranteed sale price.
• CAD values are reassessed annually and can shift meaningfully year to year, so it's worth re-checking before relying on a number that's more than a few months old.

The takeaway

If your land has an agricultural exemption, don't judge its value by your tax bill. Pull up your county's CAD record and look for the market value line specifically — it tells a very different, and usually far more accurate, story.
