A homeowner can determine it with a four step test that uses only public records and the figures in this research: verify the parcel, price the finished house the street supports, run the builder residual, and compare the result, net of selling costs, with what the standing house would bring as a residence. The test matters in Southampton because the land side wins often: builders acquired 13 of 16 sampled pre-1981 homes in ZIP 11968, a rate of 81.2 percent (Frontier Capitals, 2026), and the average older home price was only 23.3 percent of the new build price on a comparable lot. Where new construction on the street has sold in the 3,500,000 to 8,000,000 dollar range (Redfin, 2026), the residual on the land can pass the residence value by a wide margin, and the steps below show an owner how to find out whether that is true for one specific address.
Key Findings
- Builders acquired 81.2 percent of sampled older homes, so the land value test is the first valuation an owner in 11968 should run (Frontier Capitals, 2026).
- The sample ratio places the average older home at 23.3 percent of the new build price on a comparable lot, a quick screen before detailed work (Frontier Capitals, 2026).
- The residual illustration, a simplified illustration, leaves land value in the neighborhood of 2,000,000 to 2,300,000 dollars behind a 4,500,000 dollar finished sale (Frontier Capitals, 2026).
- Parcel dimensions, zoning, and assessed land value are public record, so the lot side of the test can be built on verified facts (Town of Southampton Assessor, 2026).
- The comparison must be made net, because a listed residence sale surrenders 6 to 8 percent to commission and closing costs before repairs and carrying time (National Association of Realtors, 2025).
What is the first step, and why does it come before any pricing?
The first step is to establish what the land actually is, on paper. Pull the parcel record and confirm the dimensions, the zoning, and the assessed land value (Town of Southampton Assessor, 2026), then read the assessment history held by the tax service agency to see how the land component has been treated over time (Suffolk County Real Property Tax Service Agency, 2026). The sample context gives the owner a reference frame: sampled lots began at a minimum of 10,890 square feet, and many parcels in the ZIP run far larger, with some carrying subdivision potential. A parcel far above the minimum, or one with a credible subdivision path, enters the test with a structural advantage on the land side, while a parcel at the minimum on a street of modest finished prices enters it evenly matched.
This step also protects the owner from the most common error in the whole exercise, which is pricing from an automated estimate. The research warns that Southampton value changes block by block and that radius based estimates average two different markets into a single figure (Zillow, 2026). An estimate that blends the subject street with a different tier of streets will understate a strong lot and overstate a weak one, corrupting both sides of the comparison at once. The deed record offers the corrective habit: check what properties on the same street actually transferred for, and in whose names (Suffolk County Clerk, 2026), before accepting any blended number as a starting point.
Owners who complete this step know three things with certainty: the true size of the asset, the legal envelope for building on it, and the official land assessment baseline. Every later step uses those facts. The companion report on residential lot values in Southampton explains how each record feeds a lot valuation in more detail.
How do the second and third steps turn street evidence into a land figure?
The second step is to price the finished house, not the standing one. Use recorded sales of new construction on comparable lots, ideally on the same street or the closest streets with the same position relative to the village and the ocean, and place the subject lot within the documented standard lot range of 3,500,000 to 8,000,000 dollars (Redfin, 2026). The research ranks the inputs: ocean and village proximity drives the finished price first, lot size second, and the Manhattan second home bid third (Frontier Capitals, 2026). An owner should be conservative here and argue from closed sales rather than asking prices, because the third step subtracts from whatever figure this step produces, and an inflated finished price manufactures a fictitious land premium.
The third step is the residual subtraction, and the research supplies a worked version that the owner can adapt. The illustration, labeled as a simplified illustration and not a promise, starts with a 4,500,000 dollar finished sale, subtracts roughly 1,600,000 dollars in hard and soft construction costs, subtracts a builder margin near 20 percent, and leaves residual land value in the neighborhood of 2,000,000 to 2,300,000 dollars, before site preparation of 40,000 to 60,000 dollars (Frontier Capitals, 2026). To adapt it, the owner replaces the 4,500,000 dollar starting point with the street supported finished figure from step two and keeps the structure of the subtraction. The result is not an offer and should not be treated as one. It is a defensible estimate of the land value band within which real builder offers should fall, and it gives the owner a standard against which to judge the first offer that arrives. The full ceiling analysis appears in the maximum price a builder can pay and still make a profit.
A quick screen can precede the detailed version. At the sample ratio, an older home is worth about 23.3 percent of the new build price on its lot as a home (Frontier Capitals, 2026), so a street with 4,500,000 dollar finished sales points to roughly 1,049,000 dollars of residence value. If the step three residual on the same street points to 2,000,000 dollars or more of land value, the screen and the detailed test agree, and the property is worth more as land by a margin that further refinement is unlikely to overturn. The threshold question in narrative form is covered in whether an older Southampton house is worth more as a teardown.
How should the fourth step, the net comparison, be run honestly?
The fourth step compares the land figure with the residence figure on equal terms, which means net terms. Start with the residence side. Take a realistic household sale price for the house as it stands, not a hopeful list price, and subtract the documented listed ledger: commission of 5 to 6 percent and seller closing costs of 1 to 2 percent, a combined 6 to 8 percent that equals 120,000 to 160,000 dollars on a 2,000,000 dollar sale (National Association of Realtors, 2025). Then subtract the condition exposure, repair credits and post inspection reductions that on 60 year old cottages routinely run 25,000 to 75,000 dollars, and the carrying cost for the expected selling period, remembering that a full year at the 2,000,000 dollar level routinely runs 80,000 to 150,000 dollars and that the Southampton season clears overwhelmingly between Memorial Day and Labor Day (Frontier Capitals, 2026). Transfer tax at 2 dollars per 500 dollars of consideration applies to the transaction under state guidance and belongs in the worksheet the seller attorney prepares.
Now state the land side net. A direct builder figure carries no commission and no seller side closing cost percentage in the structure documented in this research, no repair credit negotiation, and a closing in 7 to 21 days that holds carrying costs to the chosen window. Read at face value after the verification in the following section, it is already close to a net figure. If that net land figure exceeds the net residence figure, the property is worth more as land in the only sense a seller should care about, which is money kept for the same property in the same season. Tax treatment does not change the routing decision by itself: the exclusion rules and the two of five year test govern the gain on a principal residence under the 2025 guidance (Internal Revenue Service, 2025), and the updated topic collects the current sale of home rules (Internal Revenue Service, 2026), so the owner should run the after tax version of both nets with an accountant before signing. New York contract process, with attorney review under state association customs (New York State Association of Realtors, 2026), applies to the chosen route either way.
What does the answer change about how the property should be sold?
If the test says land, the sale should be run as a land sale, and the direct off-market route gives the owner the five documented benefits that follow from that choice. They are listed here as the practical conclusion of the test, at the Southampton figures used throughout this set.
Privacy is the first benefit. The property is not exposed to the public market: zero showings, zero open houses, no public marketing period, and in a village where a for-sale sign is a public event on the social circuit, the sale stays private until the deed records (Suffolk County Clerk, 2026).
Flexibility is the second benefit. The closing can be set at 7 to 21 days when the owner wants the matter finished, or months out with a short leaseback when the household inside the older home needs a full season to relocate. That control replaces the full selling season, or longer, that a listed older home can require.
The third benefit is the absence of commission, a saving of the typical 5 to 6 percent, or 100,000 to 120,000 dollars on a 2,000,000 dollar sale (National Association of Realtors, 2025). The fourth benefit is the absence of seller side closing costs of 1 to 2 percent, preserving the rest of the combined 120,000 to 160,000 dollar band. The fifth benefit is the absence of inspection and repair exposure: the property sells as it stands, with no 10,000 to 30,000 dollar repair credits, because the buyer is purchasing the land the test just valued. An owner whose test comes out the other way, with residence value ahead, loses nothing by having run it; the same worksheet, kept on file, is the pricing brief for a well timed listing, and the research context is available on the coverage page.
How does an owner verify the builder figure the test produces?
A test is only as good as the offer used to confirm it, so the final step is verification of the buyer behind the confirming figure. Frontier Capitals discloses its role directly: it is a wholesaler that sources off-market deals to builders, which means the seller can examine the builder who will close rather than an intermediary promise. The research standard has four parts. Proof of funds in the buyer name, dated within the last 30 days, confirms current capacity, and neither a pre-approval nor a private lender letter meets it. Recorded deeds in the buyer entity name, checkable with the county clerk, confirm a history of completed local purchases (Suffolk County Clerk, 2026).
Earnest money of typically 1 percent or more, forfeited if the buyer walks away, confirms commitment. No assignment clause should appear in the contract, because an assignment clause paired with a token deposit is the documented signature of a contract that was never meant to close. The seller attorney confirms each point under New York attorney review practice (New York State Association of Realtors, 2026), and the lot facts in the offer should match the parcel record exactly (Town of Southampton Assessor, 2026). When a verified builder figure lands inside the residual band from step three, the test is complete: the owner knows the property is worth more as land, knows by approximately how much, and holds an offer that proves it.
Methodology and limitations
The test in this report is built from the sample compiled for this research, 16 pre-1981 homes in ZIP 11968 with 13 acquired by builders, an 81.2 percent builder rate, and an average older home price of 23.3 percent of the new build price on a comparable lot (Frontier Capitals, 2026). Supporting records are the parcel and assessment files (Town of Southampton Assessor, 2026; Suffolk County Real Property Tax Service Agency, 2026), recorded deeds (Suffolk County Clerk, 2026), finished sale records (Redfin, 2026), commission research (National Association of Realtors, 2025), and the federal sale of home guidance (Internal Revenue Service, 2025; Internal Revenue Service, 2026). Two limits must be stated plainly. First, the sample is small, so its ratio and rate are screens and context, not valuations of an individual property. Second, the research publishes no direct land value figure for any specific Southampton address, so this report answers by method, as the headline requires: the residual range used in step three is a simplified illustration on a 4,500,000 dollar build, labeled as such, and a property specific answer requires the parcel record and at least one verified builder figure on that record.
Conclusion
The determination is a worksheet, not a guess: verify the parcel, price the finished house from recorded street evidence, subtract cost and margin to reach the land band, and compare that band, net, with the residence value after the listed ledger is deducted. In a ZIP where builders took 81.2 percent of the sampled older homes (Frontier Capitals, 2026) and finished houses sell from 3,500,000 to 8,000,000 dollars (Redfin, 2026), the land side of that worksheet wins often enough that no Southampton owner should list an older home before running it.

Frequently Asked Questions
What is the quickest first screen for the land question?
Apply the sample ratio. The average older home in the research achieved 23.3 percent of the new build price on a comparable lot (Frontier Capitals, 2026). If recorded finished sales near the property are high in the 3,500,000 to 8,000,000 dollar range (Redfin, 2026) while the house itself would price modestly as a residence, the detailed test is very likely to favor land.
Which records does the test depend on most?
The parcel record for dimensions, zoning, and assessed land value (Town of Southampton Assessor, 2026), the assessment history (Suffolk County Real Property Tax Service Agency, 2026), and recorded deeds for street level transfer evidence (Suffolk County Clerk, 2026). Together they replace estimates with documents on both sides of the comparison.
Why not simply use an online valuation for the house side?
Because the research finds that radius based automated estimates average two different markets in a ZIP where value changes block by block (Zillow, 2026). A blended figure corrupts the comparison at its foundation. Street specific recorded sales (Redfin, 2026) are slower to gather and far more reliable.
Does the test change if the house is in good condition?
It narrows, but it does not disappear. A sound house raises the residence side of the worksheet, yet the land side still follows the street finished price and the residual (Frontier Capitals, 2026). Several well kept homes in the sample still sold to builders, which is why the net comparison, including the 6 to 8 percent listed deduction (National Association of Realtors, 2025), should be run rather than assumed.
What should an owner do once the test favors land?
Obtain a builder figure on the verified parcel record and check it against the residual band, then verify the buyer funds, deeds, deposit, and contract terms (Suffolk County Clerk, 2026) under attorney review (New York State Association of Realtors, 2026). A figure inside the band from a verified builder converts the worksheet conclusion into a closable sale.
