How do I even value 20 acres in a county where the state doesn't publish sale prices

Question

I'm looking at a rural county and pulled the assessor site expecting to see what parcels sold for. There's acreage, an assessed value, an owner name, and no sale price anywhere. Someone told me a bunch of states just don't disclose that at all, which if true blows up the way I thought I'd be doing comps.

The assessed value on the parcel I'm watching is $14,600 for 20 acres. Is that a usable starting point or is it meaningless? And if I can't see sales, what do people in this niche actually use? I don't want to guess my way into paying retail for something I meant to buy at a discount.

Roughly a dozen states are non-disclosure, meaning sale prices aren't public record, so what you found on the assessor site is normal rather than a gap in the data. In those states you build value from listings and closed activity gathered elsewhere.

The assessed value of $14,600 is a weak starting point and here's why. Assessment methods vary by state and county, some assess at full market value, some at a fixed fraction of it, and rural land often carries a use-based assessment for agriculture or timber that is far below market. A parcel enrolled in a forestry program can be assessed at a few hundred dollars an acre while selling for several thousand. Treat the assessment as a clue about how the county classifies the land, not as a value.

What's usable: active listings on the land marketplaces for the same acreage band in the same and adjoining counties, and sold data from those sites where it exists. Ask a local land agent what similar parcels closed at, because agents in non-disclosure states have access through their board's records and many will share ranges. Look at price per acre, and keep your bands tight, because a 5 acre parcel commonly sells for two or three times the per acre price of an 80 acre parcel in the same township. Road frontage, legal access, and water change the number more than the raw acreage does.

One thing to check before you spend time on this parcel: if it does carry a reduced agricultural or timber assessment, changing the use or splitting the parcel can trigger back taxes or a rollback penalty in many states. That bill lands on whoever owns it at the time, and the rules differ by state, so confirm with the county assessor in writing.

The per acre point caught me off guard. So a 40 is not two twenties?

@juniper it's usually much less than two twenties, because the buyer pool for 40 acres is smaller and the payment is bigger. That gap is where a lot of this niche lives, buy the 40 and sell four tens if the county lets you split. Splitting is its own headache though, minimum lot size, survey cost, sometimes a road standard you have to meet.

Are the marketplace listings even honest, though? Half of what I browse in rural counties looks like it's been sitting at the same asking price for a year.

@wren stale listings still tell you something, they tell you the ceiling nobody paid. I've been keeping a spreadsheet with list price, acreage, days it's been up, and whether it has legal access. After a couple of months the pattern of what disappears fast versus what sits is more useful to me than any single number.

In the low price counties I follow, the assessment being tiny is often the whole story, the county has the land at $300 an acre because it's enrolled in timber and the owner's tax bill is $60. That owner has no pressure to sell at all. My better responses come from parcels where the tax bill is out of line with what the owner thinks the land is worth.

Is calling the local agent for closed ranges something they'll do for a stranger with no listing to give them? I'd assume that call goes badly more often than not.
