Older homes south of the highway in Southampton sell primarily as land, and their prices follow the finished houses that will replace or surround them rather than the cottages and ranch homes currently standing. Across 11968, the sample compiled for this report found 16 pre 1981 homes, of which builders acquired 13, and the average older home traded at 23.3 percent of the price of a new build on a comparable lot (Frontier Capitals, 2026). Applied to the local finished range, that ratio is informative: new construction on standard lots has sold from 3,500,000 to 8,000,000 dollars depending on village versus south of the highway location, ocean proximity, and lot size (Redfin, 2026), and the south of the highway area occupies the ocean side of that range. Where a finished house supports 4,500,000 dollars, the worked example in the research puts the older home trade near 1,049,000 dollars (Frontier Capitals, 2026), while the residual a builder can pay for the lot itself runs higher, at 2,000,000 to 2,300,000 dollars before site preparation on the same illustration. No published figure splits 11968 into a north and south percentage, and this report does not invent one; the south side premium is documented qualitatively, through ocean proximity ranking first among the value drivers, and it is priced parcel by parcel.
Key Findings
- Builders bought 13 of the 16 older homes in the 11968 sample, so the typical older home sale in this market is a land transaction in substance (Frontier Capitals, 2026).
- Older homes averaged 23.3 percent of a comparable new build price, putting a 4,500,000 dollar finished house alongside an older home trade near 1,049,000 dollars (Frontier Capitals, 2026).
- Finished prices on standard lots run to 8,000,000 dollars at the ocean influenced end of the range (Redfin, 2026), which is the segment the south of the highway area belongs to.
- The residual land value inside a 4,500,000 dollar finished sale is illustrated at 2,000,000 to 2,300,000 dollars before site preparation, well above the average older home trade (Frontier Capitals, 2026).
- The research publishes no north versus south percentage split for 11968, so any exact premium figure for this area would be invented; the premium is documented by driver ranking and by street level sales instead.
Why does location south of the highway change what an older home is?
The highway is the informal dividing line of Southampton pricing because it separates the ocean side streets from the inland ones. South of it, every parcel is measured by its distance to the water, and the research ranks ocean proximity first among the drivers of the residual, ahead of lot size and ahead of the Manhattan second home bid. An older house on the south side therefore sits on the most contested ground in the ZIP, regardless of the condition of the house itself. North side parcels can be excellent building sites, but they compete with more substitutes; south side parcels compete with almost none.
That scarcity shows in the finished product. New shingle style builds south of the highway fill their lots nearly to the setback lines and sell at the top of the 3,500,000 to 8,000,000 dollar range (Redfin, 2026). It also shows in who buys the older stock. The 81.2 percent builder acquisition rate in the sample (Frontier Capitals, 2026) is a ZIP wide figure, yet the economic logic behind it strengthens toward the ocean, because the spread between the older home price and the finished price is widest where finished prices are highest. A household buyer for a south side cottage faces the same arithmetic from the other direction: the purchase price plus a serious renovation approaches the cost territory of newer houses, which pushes many households out and leaves the field to builders.
Parcel records are the grounding evidence for any individual address. The assessor records dimensions and zoning for each lot (Town of Southampton Assessor, 2026), and assessment records show how the tax authorities distribute value between land and improvement on the south side (Suffolk County Real Property Tax Service Agency, 2026). On many older south side parcels the assessed land share is already the dominant share, which is the official record quietly confirming what the builder bids say openly. The north south comparison itself is examined head on in the report on values in the two halves of Southampton.
How should a south side price be built from the evidence?
Start from the street, not from the ZIP. Southampton value changes block by block, so the first step is identifying finished sales on the same street or the nearest comparable ocean side streets (Redfin, 2026). Automated estimates are a weak substitute here, because a radius based figure averages ocean side and inland sales into a single number that describes neither market (Zillow, 2026). With a defensible finished price in hand, run the residual: subtract construction costs illustrated at roughly 1,600,000 dollars and a builder margin near 20 percent from the finished price, then subtract site preparation of 40,000 to 60,000 dollars, and the remainder is the land value a builder can pay while still earning the margin (Frontier Capitals, 2026).
Then place the standing house honestly in the calculation. For a redevelopment buyer, the house contributes nothing beyond the seller occupancy until closing, and the research quantifies the point through renovation: a 200,000 dollar update to a 1960s cottage might add 140,000 to 180,000 dollars if the buyer lives in the home, and returns 0 dollars if the buyer redevelops (Frontier Capitals, 2026). For a household buyer, the house contributes its value as a residence, which on the south side must be weighed against the carrying reality of the area: property taxes counted among the highest in the country, insurance, and maintenance on an older structure, within a full year carrying range of 80,000 to 150,000 dollars at the 2,000,000 dollar level (Frontier Capitals, 2026). The higher of the two buyer valuations, land residual or residence value net of costs, is the realistic selling range for the property.
Deed records close the loop. Recorded deeds in the county system show what builder entities paid for older homes on specific south side streets (Suffolk County Clerk, 2026), and those closed trades, adjusted for lot size, are more persuasive than any asking price. Background on the town owner base, heavily weighted toward seasonal and second home ownership, comes from the Census town profile (U.S. Census Bureau, 2025) and helps explain why demand on the ocean side persists through slow national quarters. The lot size side of the same calculation is treated in the study of larger lots in 11968.
What separates a strong south side result from a weak one?
Three things, in the experience documented in this research. The first is timing within the season. The Southampton resale market clears overwhelmingly between Memorial Day and Labor Day, and while builder bids are less seasonal than household demand, the competitive tension that produces the best land prices is strongest when several builders are actively assembling their next projects. An older home listed in October that sits through winter can absorb a full year of carrying costs before it trades. The second is lot readiness. A parcel with clear dimensions, a known zoning picture, and a documented certificate of occupancy history for the existing house is easier for a builder to underwrite than a parcel with open questions (Town of Southampton Assessor, 2026). Sellers who assemble the parcel file before going to market remove the discounts buyers apply for uncertainty.
The third is competition. A single builder offer is a data point; two or three bids on identical parcel information are a market. Because the buyer pool for south side older homes is overwhelmingly builders, soliciting bids on the same data, the same closing window, and the same as is terms makes the offers directly comparable, and the highest bid then reflects the street residual rather than one builder margin policy. National figures offer a caution from the household side of the market: in late 2025 the median time on market was 51 days and roughly 15 percent of pending sales fell out of contract (Redfin, 2025), frictions that a competitive builder process largely avoids. The typical sold home nationally spent 46 days on market in the 2026 update (Redfin, 2026), a timeline that says nothing about Southampton season risk but underlines how much slower the ordinary route is than a direct closing.
What do the sampled trades say about the range a south side seller should expect?
Sampled trades describe a market with a wide honest range, and a south side seller should expect an outcome inside it rather than a single ZIP wide number. At the center of the distribution sits the documented average: an older home at 23.3 percent of the finished price of a comparable new build (Frontier Capitals, 2026). Around that center, the variables that move a specific property are all visible in the parcel record and the street record. A larger lot moves the outcome up, because the finished house and grounds it supports are larger; the sample minimum of 10,890 square feet (Frontier Capitals, 2026) is a floor that many south side parcels exceed comfortably, and assessor records confirm the dimensions case by case (Town of Southampton Assessor, 2026). A shorter walk to the water moves the outcome up, because ocean proximity is the first driver. A house that a household could genuinely occupy moves the outcome up in season, because it opens the second buyer pool. A house with open septic, occupancy, or title questions moves the outcome down, because each question becomes a deduction in a builder underwriting.
Sellers sometimes ask whether the high end of the finished range, 8,000,000 dollars (Redfin, 2026), should anchor their expectations. It should anchor only the properties whose streets and lots actually produce finished sales at that level. The discipline that protects a seller from both overpricing and underpricing is the same discipline used throughout this report: build the price from the street, the parcel, and the deeds, in that order (Suffolk County Clerk, 2026). An asking figure built that way can be defended to any buyer, any appraiser, and any family member asking why the house sold for what it did, which in long held south side properties is often a constituency of its own. Where the property is an estate asset, that defensibility has a value beyond the transaction, and it is one more reason to prefer documented bids over hopeful listings.
What does the off market route add up to on the south side?
The five direct sale benefits apply with particular force on the ocean side of the highway. Privacy comes first: no showings, no open houses, no public marketing period, and no sign on a street where a sign is a public event on the village social circuit. For a family that has held a south side house for decades, the sale can stay unannounced until the deed records, which many sellers regard as part of the value. Timing is second: a direct buyer closes in 7 to 21 days on the seller chosen date, or months out with a short leaseback, instead of a full selling season or longer for a listed older home.
Third, no commissions: the typical total commission of 5 to 6 percent is 100,000 to 120,000 dollars on a 2,000,000 dollar sale (National Association of Realtors, 2025), and south side prices frequently exceed that illustration, scaling the saving with the price. Fourth, no seller closing costs beyond what the contract assigns: listed sales add 1 to 2 percent in seller side costs, and commissions plus closing costs together commonly reach 6 to 8 percent, typically 120,000 to 160,000 dollars on a 2,000,000 dollar sale (National Association of Realtors, 2025). The state transfer tax runs at 2 dollars per 500 dollars of consideration (New York State Department of Taxation and Finance, 2026), one of the lines a seller should map before signing any contract. Fifth, no inspections or repairs: the sale is as is, without the 10,000 to 30,000 dollar repair credits a listed older house invites after inspection, and without renovation spending that a redevelopment buyer values at zero. Route and parcel questions can be taken up through the contact page or the coverage summary.
How should a south side seller screen the buyers who bid?
Screening matters more where the numbers are large. Require proof of funds in the buyer name dated within the last 30 days; a pre approval or a lender letter is not evidence of the ability to close a land purchase. Check the entity against recorded deeds in the county records to confirm a history of closed purchases rather than a history of contracts (Suffolk County Clerk, 2026). Insist on earnest money of 1 percent or more, forfeited if the buyer walks, and on a contract with no assignment clause, since an assignment clause with a token deposit is the signature of a contract never meant to close.
Frontier Capitals discloses its position plainly: it is a wholesaler that sources off market deals to builders. A south side seller is entitled to know the ultimate builder, the source of funds, and the closing timeline before signing, and the verification steps above give the seller the means to confirm each one independently.
Methodology and limitations
The figures here come from the 11968 sample of 16 pre 1981 homes, 13 builder acquired, with a minimum lot of 10,890 square feet and an average older home price of 23.3 percent of a comparable new build (Frontier Capitals, 2026). The sample is ZIP wide; it is not broken into a south of the highway subsample, and no north versus south percentage split exists anywhere in the research. The south side premium is therefore stated qualitatively, grounded in the ranking of ocean proximity as the first value driver and in the documented finished price range, and any precise premium percentage would be an invention. The residual numbers come from a simplified worked illustration in the research and vary by parcel.
Conclusion
Older homes south of the highway are selling, in substance, as ocean side building sites with houses on them. Their prices are set by finished values that reach 8,000,000 dollars, by a builder demand rate above 80 percent across the ZIP, and by residuals that can place land value above 2,000,000 dollars on a mid range finished assumption. A seller who prices from the street level evidence, the parcel file, and competing builder bids will land close to the true range; a seller who prices from an automated average or a regional median will not.

Frequently Asked Questions
Is there an exact premium for the south of the highway area?
No exact figure is published in this research. The premium is documented qualitatively: ocean proximity ranks first among the value drivers, and finished prices reach the top of the 3,500,000 to 8,000,000 dollar range on the ocean side (Redfin, 2026). Parcel level residuals and street deeds are the way to price a specific property.
What did older homes average against new builds in the sample?
The average older home traded at 23.3 percent of the price of a new build on a comparable lot, illustrated by an older home near 1,049,000 dollars against a 4,500,000 dollar finished house (Frontier Capitals, 2026). South side finished prices often run higher, which lifts the land side of the comparison. Individual results vary with lot size and street.
Should I renovate a south side cottage before selling it?
The research argues caution. A 200,000 dollar update might add 140,000 to 180,000 dollars for a live in buyer and returns nothing when the buyer redevelops (Frontier Capitals, 2026). Given that builders took 81.2 percent of sampled older homes, redevelopment is the likely outcome. Establish the buyer type before spending.
How quickly can a direct sale close on the south side?
A direct builder buyer typically closes in 7 to 21 days, or months out with a leaseback if the seller prefers (Frontier Capitals, 2026). Once listed, an older home here may still be waiting for its buyer when the season ends, and sometimes well after that. The direct route also removes the commission of 5 to 6 percent (National Association of Realtors, 2025).
Where can I verify what a builder paid for a nearby house?
Recorded deeds are kept in the county records and can be searched by buyer entity and address (Suffolk County Clerk, 2026). Closed deeds on the same street, read alongside lot dimensions from the assessor, give the closest evidence of the local land market. Asking prices and automated estimates are weaker evidence.
