The county's $6,000 is a tax appraisal. The seller's $15,000 is an ask. Neither one is the price the land will trade for, and a gap that wide is normal in Alabama. The county figure still matters, because it is the only number on that tract that somebody figured the same way for every parcel around it. Here is what it is and how to put it to work.
The County Figure Is an Estimate Made for Tax Purposes
Every parcel in an Alabama county gets a value from the county revenue commissioner (some counties call the office the tax assessor). That value is the appraised value. The office's job is to put a fair market value on every parcel so the tax bill can be figured, and to do it the same way across the whole county. It uses the state's appraisal manual and a mass appraisal process, which means models and land tables. Nobody walked your tract with a clipboard.
The Alabama Department of Revenue's real property section maintains that manual. Each year every county runs a sales ratio study to check how its appraisals line up with the market and whether a reappraisal is due. So the county is trying to track market value. It is just doing it one county at a time, on a schedule, with a formula that has to hold up on thousands of parcels at once. On a single tract the number can lag, and it will almost never carry the premium a seller puts on frontage, a view, or a pond.
Appraised, Assessed, and Market Value Are Three Different Numbers
This is where first-time buyers get tangled, because the tax record shows two values and the seller is quoting a third.
Appraised value is the county's estimate of what the parcel is worth. That is the $6,000 an acre.
Assessed value is the slice of the appraised value that actually gets taxed. Alabama sorts property into classes, and each class has its own percentage. The Department of Revenue's property tax assessment page lays it out. Class III covers "all agricultural, forest, and single-family owner occupied residential property" and is assessed at 10 percent. Class II, everything not otherwise classified, is assessed at 20 percent. The formula is on the same page: appraised value times the class percentage equals assessed value. Most undeveloped land you would look at falls in Class III. So a $6,000 appraised acre has an assessed value of $600, and the tax rate is applied to the $600.
If you ever see a tract on a tax site at $600 an acre and think you found the deal of the decade, that is the assessed number. It is a tax accounting figure, and nobody thinks the land is worth that.
Market value is what a willing buyer pays a willing seller. Nobody in the courthouse decides it. The seller's $15,000 is an opinion about it, and so is whatever you end up offering.
Why You Can't Just Look Up What the Neighbor Paid
In a state that publishes sales, you would settle this argument in ten minutes. Pull the last three sales on the road, divide by acres, and you have your comps. In Alabama the price does get recorded: when land changes hands the deed goes to the probate office with the price or value stated and a recording tax paid on it. But there is no searchable public database of those prices. Finding them means pulling deeds one at a time, and the recorded figure can be the county's appraisal rather than what was paid. The number you can look up in a minute is the county's appraisal. Listing sites that show "sold" prices in Alabama are often showing the asking price at the time the listing closed, or an estimate, and they don't always say which.
This is why the county number carries more weight here than it would elsewhere. It is the one figure that exists for every parcel and was produced the same way for each, and when there are no sales to look at, a consistent estimate beats no estimate. Which raises the next question: consistent compared to what?
Current Use Can Push a Timber Tract's Number Even Lower
Some low county numbers are low for a reason that has nothing to do with the dirt. Alabama lets owners of agricultural and forest land apply to have it valued on its current use, with no regard for what the market might pay. The Department of Revenue's current use page defines it as "the value of eligible taxable property based on the use being made of that property." The state figures it each year from a formula built on capitalization rates, crop data, production costs, and pulpwood prices. The owner applies with the county between October 1 and January 1, and once approved does not have to reapply unless the property changes hands.
Auburn University's College of Agriculture puts the effect plainly on its Alabama Timberland page: "The current use value of timberland may be well below market value, especially near metropolitan areas." That was the point of the law, to keep a family from being taxed off a farm because a subdivision went in next door.
For you, the buyer, it means a 60-acre pine tract in a growing county can carry an appraised value that reflects pulpwood, and no homesites at all. That number answers a different question than the one you are asking. Two more things to know. If you buy the tract and convert it to another use within two years of the sale, the county recalculates the three prior years of taxes at the sale price or market value, whichever is higher, under the rollback rule, and that bill is yours. And current use does not follow the land through a sale. A new owner has to apply again.
What the Shelby County Numbers Look Like
Here is the county figure in practice. LandScout tracks 16,727 undeveloped parcels in Shelby County. These are the median appraised land values per acre by parcel size, from the county's own roll as of September 2026.
| Parcel size | Parcels | Median appraised land value per acre |
|---|---|---|
| Under 5 acres | 2,338 | $14,440 |
| 5 to 20 acres | 2,468 | $8,990 |
| 20 to 50 acres | 1,629 | $6,803 |
| 50 to 100 acres | 578 | $6,422 |
| 100 acres and up | 510 | $5,403 |
Read down the last column and the pattern is the one you would expect. Small parcels appraise high per acre, big ones low. A 3-acre homesite lot and a 150-acre timber tract are priced by different rules, by the county and by everyone else. So when a seller wants $15,000 an acre for 40 acres, the right comparison is the 20-to-50 band at $6,803. That ask is more than double the county median for tracts its size. It might still be worth it. But the seller should be able to say why, in terms of the land itself. The Shelby County page has the rest of the county-wide numbers, including flood, soil, and access.
How to Use the County Figure Without Misreading It
The county number works as a floor, a yardstick, and an alarm. Nobody should write an offer off it alone.
A floor. An ask under the county appraisal is unusual, and when you see one there is usually a story: a landlocked parcel, a flood zone, a title problem, a family that just wants out. If the asking price is under the appraisal, don't celebrate. Ask why.
A yardstick. Because every parcel in the county was appraised by the same office with the same tables, the number is best used sideways, comparing parcels to each other. Pull the appraised value per acre on the tract you like and on five or six of similar size nearby. If yours is at $6,000 and the neighbors sit at $5,500 to $6,500, the county sees them alike. If yours is at $6,000 and the neighbors are at $12,000, something on your tract is dragging it down, and you want to know what before you make an offer.
An alarm. The ratio of asking price to appraisal is a quick test. An ask well above the county median for its size band is normal around a metro. An ask at four or five times needs a reason, especially on a tract with no frontage, no utilities, and a creek through the middle. The county figure is how you know to push back and ask for it.
What the county number cannot do is tell you what to pay. For that you still need the things the appraisal doesn't carry: whether the ground will perk, where the water line ties in, what the FEMA map says, and why the seller is selling. That is the research the person who built LandScout watched his father do the hard way, from the passenger seat of the truck. He sold land for a long time, and his read on a county appraisal was the same every time. It tells you where the conversation starts. The information was public. It just wasn't in the truck.
LandScout pulls the appraised value, the value per acre, and the size-band medians into one parcel file, so the comparison takes minutes. The pricing page lists what the free and paid plans include.
