How Much Is My Land Worth? Why Online Estimates Are Wrong for Vacant Land

By Jeremy King, Co-founder, King Land Buyers · October 16, 2026 · 9 min read

You have a parcel you are thinking about selling, you typed the address into a home-value site, and nothing came back. Or a number came back that looks nothing like what neighbors have been selling for. Either way you are stuck on the same question: what is this land actually worth?

Vacant land is worth what a buyer will pay for a comparable parcel in the same market right now. That number starts with recent sales of similar acreage nearby, then adjusts for legal road access, zoning, utilities, topography, wetlands or flood exposure, and anything owed against the property. No automated tool produces it for land, which is why your search came back empty.

Why there's no Zestimate for your land

This is not a glitch on your parcel. Zillow's own documentation for the Zestimate says estimates are available only for residential properties, and that large multi-family buildings, vacant land and commercial properties are not eligible. The same page says the estimate is a starting point and "is not an appraisal and can't be used in place of an appraisal."

The reason is the data, not your parcel. An automated model finds dozens of nearby house sales that match on square footage, bedrooms and age, then averages the differences away. Land does not give it that. A county may record only a handful of raw land sales in a year, and no two are interchangeable: one has 300 feet of paved road frontage, the next is reached by an easement across a neighbor, the third is 40 acres with a creek through the middle. Some states do not publicly report sale prices at all, making raw land effectively invisible to national tools.

How a land price actually gets built

Appraisers and buyers use the same method on land: comparable sales. IRS Publication 561 puts the standard plainly. Fair market value is "the price that would be agreed on between a willing buyer and a willing seller, with neither being required to act, and both having reasonable knowledge of the relevant facts." The comparable sales method compares a property with several similar properties that have sold, and those selling prices "after adjustments for differences in date of sale, size, condition, and location" indicate the value.

That publication is unusually specific about unimproved land. It directs the appraiser to compare location, size, and zoning or use restrictions; accessibility, road frontage, and utilities; riparian rights and easements; and soil, vegetation, and mineral rights. If you want the list of what moves a land price, that is it, written down by the IRS.

In practice: find three to five parcels in the same market that sold in the last year or two, confirm each was an arm's-length sale rather than a family transfer, then adjust each for how it differs from yours. What is left is a range, not a single figure. Anyone who gives you a precise number without looking at the parcel is guessing.

What moves the number most

Access is first, and it is not close. A parcel you can legally drive to is in a different price class than one you cannot.

If the parcel has unpaid taxes, the amount owed and the county's timeline both matter, and we walk through that in Behind on Property Taxes on Vacant Land?

Why the county's assessed value isn't your answer

The assessed value on your tax bill exists to spread the tax burden across every parcel in the county. It is produced by mass appraisal — one office valuing tens of thousands of parcels at once, on a reassessment cycle that in many places runs several years between updates. It is not a market price, and not an offer.

On vacant land the gap tends to be wider than on houses, in both directions. A county may still carry raw acreage at a figure set before the last run-up in prices, or carry a lot at a buildable residential value that stopped being realistic once a wetlands determination came back. Treat the assessment as one data point, and the tax on it as a real cost.

Why a neighbor's price per acre can mislead you

Price per acre is the most-quoted number in land and the easiest to misread, because it does not hold steady as parcels get bigger. Smaller parcels almost always sell for more per acre than large ones nearby: the buyer pool for a 2-acre homesite is far larger than the pool for 200 acres, and fixed costs like a survey and closing spread over less ground.

Three other traps:

• A list price is not a sale price. The parcel down the road asking a number for three years shows what one owner hopes for, not what the market pays.
• A split parcel is not your parcel. Land sold off in finished lots, with access and utilities already in, carries the cost and time of that work in its price.
• A letter in your mailbox is not a valuation. The figure in a mailed offer is usually set before anyone has looked closely at your access or title; we explain how to read them in Those 'We Buy Land' Letters: Which Ones Are Real?

Three ways to get a real number

Which fits depends on why you want the number. If you are settling an estate or dividing property among heirs, an appraisal is the document that holds up. If you want the most the market will bear and can wait, list with an agent — we lay out that tradeoff in Selling Land Without a Realtor. If you want to know what you can have in hand soon, a written cash offer answers that, and how long a land sale takes is the other half.

A cash offer and a list price answer different questions. A cash buyer is pricing in the holding time, the closing costs, and the risk that an access or title problem turns up after the contract is signed. That is why a cash number is generally below what the same parcel might eventually bring after months on the market. The difference buys certainty and speed.

What to have ready before you ask anyone

You will get a tighter answer, faster, with four things: the parcel number from your tax bill, the county and state, your best sense of the acreage, and whether anything is owed on it. If you know how the property came to you — bought it, inherited it, got it in a divorce — say so, because that determines who has to sign at closing.

You do not need a survey, a cleared lot, photographs or a corrected deed first — buyers and appraisers work from county records. If the deed is still in a parent's name or the taxes are behind, share that up front; a local attorney or the county can confirm what your situation requires.

Common questions

Why doesn't Zillow show a value for my vacant land?

Because vacant land is excluded. Zillow's documentation says Zestimates are available only for residential properties, and that vacant land and commercial properties are not eligible. There is also often too little comparable sales data on raw land for any automated model to work with.

Is my land worth the county's assessed value?

Not usually. Assessed value is calculated to apportion property tax, using mass appraisal on a multi-year reassessment cycle, so it can sit well above or well below what parcels are actually selling for. Use it as context and as a measure of your annual carrying cost, not as a price.

How do I find what land sold for near me?

Start with your county's property records or GIS site, which in most counties lists recent sales by parcel and is free to search. Filter for vacant parcels of similar acreage within a few miles, sold in the last year or two, and ignore family transfers. In states that do not publicly disclose sale prices, you will need an appraiser or an agent with access to sold data.

Do I need an appraisal to sell my land?

An appraisal is ordered when a buyer is borrowing, because the lender requires one. In a cash sale there is no lender and no appraisal is ordered. You can still hire a licensed appraiser yourself if you want an independent written number, and you would pay for it directly.

Does size change the price per acre?

Yes, and it is one of the biggest reasons owners misjudge their land. Small parcels generally sell for more per acre than large ones in the same area, because far more buyers can afford a few acres than a few hundred. Applying a small-lot per-acre figure to a large tract produces a number no buyer will meet.

What hurts a land value the most?

No legal access, more than anything else. After that: zoning that rules out the use buyers want, mapped wetlands or a high-risk flood zone over the buildable area, and a title problem such as an unresolved estate or a lien. Each shrinks the pool of buyers who can act, and a smaller pool means a lower price.

So what is your parcel worth?

Nobody can tell you from the address alone. What you can do is get a number on the actual parcel. Tell us where the property is and we will research it and come back with a researched cash offer — no fees, no agents, no obligation — and you can close in as little as two weeks.
