Does a Dix Hills Seller Collect the Premium That Bidding Wars Suggest? Reading Redfin, Zillow, Realtor.com and the Census Midcentury Homes

Why do the Dix Hills price figures disagree?

The figures differ by source and by area. Redfin's city median of $1,324,124 is a three-month figure for all home types through August. Realtor.com's $1,487,500 is a single-month median sold price for May, 12.3% above Redfin's, computed here. Zillow's $1,112,431 is an index of typical value across all homes, 16.0% below Redfin's median, computed here. Redfin's postal area median of $949,589 is 28.3% below its own city median, which shows how much the postal area, which takes in neighboring streets, differs from Dix Hills.

The year-earlier values all point up. Redfin's rise of 10.3% implies about $1,200,475 a year earlier. Zillow's rise of 8.4% implies about $1,026,228. Realtor.com's rise of 41.67% implies about $1,050,000, and its three-year rise of 79.76% implies about $827,000 three years earlier. A single-month rise of 41.67% is far larger than the other readings, and since the page shows a listing median that is flat, the likely cause is a small number of large sales, which is an inference. It is reported as printed and not relied on.

Per-foot prices tell a quieter story. Redfin's $436 for the city is up 1.0%, which implies about $432 a year earlier, and its $423 for the postal area is down 2.5%, which implies about $434. Realtor.com's $487 is up 14.32%, which implies about $426. A median price that rose 10.3% with a per-foot price up only 1.0% suggests that larger houses made up more of the sales, which is a plausible mix effect in a town of large lots.

Listings sit near sales. Realtor.com's listing median of $1,399,499 is 5.7% above Redfin's sold median and 5.9% below Realtor.com's own sold median, computed here. Where sold prices are at or above asking prices, the ask is not a ceiling, and a seller who lists low to start a bidding war is taking the risk that it will not happen. Active listings of 114 are down 3.37%, which implies about 118 a year earlier, a stable and small supply.

The Census owner value of $695,200, plus or minus $12,757, is 47.5% below the Redfin city median, computed here, and 4.2 times the Census median household income of $164,589. The gap is not an error. The postal area is large, with 65,747 residents, and the Census figure is an owner's own estimate across all of it, so it should not be read as the value of a Dix Hills house.

The area difference is the main thing to take from these numbers. The postal area that includes Dix Hills reaches into neighboring streets with smaller, older houses, and its sold median is 28.3% below the city median on the same site and in the same months. An owner who reads a postal area figure will underestimate a large house in Dix Hills, and an owner who reads a single-month city figure may overestimate it. The fair comparison is a sale of a house of the same size, age and lot within the last few months, and a buyer will build that comparison before making an offer.

How hot is Dix Hills, and what do bidding wars mean for a seller?

Redfin rates Dix Hills very competitive, with a score of 82 out of 100, and the postal area 88. Many homes get multiple offers, some with waived contingencies. The average home sells about 2% above list and goes pending in around 25 days, and hot homes sell about 7% above list in around 18 days. On a $1,324,124 sale, 2% is about $26,482 and 7% is about $92,689, computed here.

The sale-to-list ratio is above 100%. Redfin shows 102.5%, up 0.4 points, which implies about 102.1% a year earlier, and 103.5% for the postal area. Realtor.com shows 99% for May, a month in which many homes were still being listed, and the two sources can both be right at different dates. More than half of Dix Hills sales, 56.4%, closed above list, and 64.9% in the postal area.

Speed is high. Redfin shows a median of 23 days on market against 21 a year earlier, which is two days slower and still under a month. Zillow's spring reading was around 26 days to pending, and Realtor.com's figure for May is 36 days, up 9.09%, which implies about 33 days a year earlier. A home priced to the market sells within a month, and the small slowing is within normal noise.

Price drops have fallen. Redfin shows 19.1% of listings with price drops, down 8.8 points, which implies about 27.9% a year earlier, and 22.6% for the postal area, down 3.1 points. Fewer cuts and more bids mean that sellers have had the better of the year. Redfin counted 89 sales in August, up 20.6%, so volume is also higher, and 114 active listings are about 1.3 times a month of sales, computed here and an inference.

The practical meaning for a seller is that a bidding war is possible and not guaranteed. In a market where 56.4% of homes sell above list, 43.6% do not, computed here, and the average premium of 2% is small beside the costs of a public sale. A seller who wants certainty can compare a private offer with the expected price from a listing, less fees, less repairs and less the time and disruption of showings.

Seasonality is likely to matter. Spring is the usual time for a family to buy, and many sellers list in the weeks after the winter holidays. The pages do not break out sales by month, so any seasonal pattern here is an inference. What the pages do show is that the season of May and the season of August both produced homes that sold in about a month, which suggests that a well-priced house does not need to wait for a particular month. A seller who has a fixed date can use that fact in deciding whether to list or to ask for a private offer.

What do the midcentury homes of the Dix Hills postal area look like?

The stock is mostly from the postwar boom. Of 22,409 housing units, 5,074, or 22.6%, were built in the 1950s and 5,890, or 26.3%, in the 1960s, so 10,964 units, 48.9%, date from those two decades. Another 1,619, 7.2%, were built before 1940, 1,617, 7.2%, in the 1940s, 3,271, 14.6%, in the 1970s and 2,243, 10.0%, in the 1980s. In all, 17,471 units, 78.0%, were built before 1980. The median build year is 1965.

Little has been built since. The 1990s add 1,187 units, 5.3%, the 2000s 715, 3.2%, the 2010s 668, 3.0% and 2020 or later 125, 0.6%, so 1,508 units, 6.7%, were built since 2000. Land is scarce, and a buyer who wants a new house often buys an old one and rebuilds or renovates. That makes the lot, not the house, a large part of the price, and a private buyer can quote on either basis.

Houses dominate. Of the units, 18,603, or 83.0%, are detached, 1,533, or 6.8%, are attached, 1,262, or 5.6%, are in buildings of two to four units and 866, or 3.9%, are in buildings of five or more. Mobile homes make up 140 units, 0.6%. Vacancy is only 920 units, 4.1%, and of those, 623, or 67.7%, are vacant for reasons outside the usual categories, 94, or 10.2%, are for sale only, 91, or 9.9%, are for rent, 82, or 8.9%, are seasonal and 30, or 3.3%, are sold and not yet occupied.

The homes are large. Of 18,443 owner households, 7,148, or 38.8%, live in a three-bedroom home, 5,700, or 30.9%, in a four-bedroom and 3,192, or 17.3%, in one with five or more bedrooms, so 87.0% have three or more bedrooms and 48.2% have four or more. Only 2,403 owner households, 13.0%, live in a home with two bedrooms or fewer.

Renters are a small group. Of 21,489 occupied homes, 3,046, or 14.2%, are rented, and 928 of those households, 30.5%, moved in since 2020. Of the rented homes, 194, or 6.4%, have no bedroom, 758, or 24.9%, one bedroom, 920, or 30.2%, two bedrooms and 1,174, or 38.5%, three or more bedrooms. Many rentals are houses or parts of houses, and the Census median rent is $2,105.

Midcentury houses have particular features. Many of the 1950s and 1960s homes in the area are split-levels, ranches and colonials on lots of an acre or less, and many have been extended over the decades. A buyer will look at how the additions were built, whether permits were taken out and how the heating and cooling were updated. A seller who has the papers for each project in one place avoids the delays that arise when a buyer's inspector asks for them, and a private buyer can often take the house with the papers as they are.

Who owns the homes, and what do they spend?

Owners are the large majority. Of 21,489 occupied homes, 18,443 are owner-occupied, 85.8%, and 3,046 are rented, 14.2%. The Census median household income is $164,589, and the median owner value is $695,200, 4.2 times income, computed here. Incomes are high, and the owner value reflects the whole postal area, so a household in Dix Hills itself is likely to be wealthier and to own a more valuable house.

Tenure is long. Of 18,443 owner households, 139 moved in during 2023 or later and 1,687 between 2020 and 2022, so 1,826, or 9.9%, moved in since 2020. Another 5,277, 28.6%, moved in between 2010 and 2019, 4,234, 23.0%, between 2000 and 2009, 3,374, 18.3%, in the 1990s and 3,732, 20.2%, before 1990. In all, 7,106 owners, 38.5%, have been in place since before 2000, which is a long hold for a market that has risen so far.

Long tenure means large equity and a low basis. A household that bought in the 1980s has seen the value of its house multiply, and a sale may produce a large taxable gain. This brief gives no tax advice, but owners in that position often want a clean number with no surprise costs before they decide, and they often want to choose the date.

Costs are moderate. Of 18,443 owners, 10,889, or 59.0%, have a mortgage and 7,554, or 41.0%, do not. Among owners with a mortgage, 3,741, or 34.4%, spent 30% or more of income on housing, and 1,583, or 14.5%, spent half or more. Among owners without a mortgage, 1,712, or 22.7%, spent 30% or more, which reflects property taxes on large houses. In all, 5,453 owner households, 29.8% of those with a computed figure, carry a heavy cost.

The population is middle-aged and older. Of 65,747 residents, 12,051, or 18.3%, are under 18, 4,749, or 7.2%, are 18 to 24, 7,321, or 11.1%, are 25 to 34, 8,289, or 12.6%, are 35 to 44, 20,437, or 31.1%, are 45 to 64 and 12,900, or 19.6%, are 65 or older. Sellers here are often empty nesters leaving a large house, or families who have grown, and for each a fixed closing date matters.

Put together, the picture is of a settled community of long-time owners in their middle and later years, with large houses, high incomes and large equity. Such an owner is not forced to sell, and for that reason the decision usually turns on timing and certainty. A seller who is not in a hurry can wait for a bidding war, and one who wants to move on a fixed date, or to avoid a season of showings, has a good reason to ask what a private buyer would pay and on what terms. Readers comparing markets can also read the Sag Harbor brief and the Southampton brief.

What should a Dix Hills owner ask, and what does a private sale change?

Five questions are worth asking. Is my house priced by the city figures or by sales on its own streets? Is the value in the house or in the lot? How likely is a bidding war, and what happens if there is none? What will the fees be? How much of the price survives the buyer's inspection?

Fees are simple arithmetic, and no rate is assumed here. Each 1% of a $450,000 sale is $4,500, of a $725,000 sale is $7,250 and of a $1,200,000 sale is $12,000. Three percent is $13,500, $21,750 and $36,000, and five percent is $22,500, $36,250 and $60,000. A seller can put their own quoted costs into those rows. On the Redfin median of $1,324,124, 1% is $13,241, 3% is $39,724 and 5% is $66,206.

A private sale has no showings and no neighbors talking about it, which is the first benefit. In a quiet residential town, a string of open houses and strangers on the street is not what every owner wants. The second benefit is a closing date that suits the seller, which helps a household that must find a new home before it sells the old one.

The third and fourth benefits are no commission costs and no closing costs, and the fifth is no inspection repairs. In a postal area where 78.0% of homes were built before 1980, an inspector will look at the roof, the heating, the wiring, the plumbing and any older materials, so the fifth is worth pricing. A buyer who takes the house as it stands leaves the seller no repair list.

Maison Off-Market buys luxury homes and estates directly from their owners and speaks only to sellers. It does not say that a private sale always beats a public listing, and in a market where more than half of homes sell above the ask, an owner is right to compare an offer with what the same home would net after costs.

Methodology and limitations

Each page's date, title and place were read before use. The Redfin city and postal area pages are for the three months ending August 2026. The Zillow page was updated April 30, 2026, and the Realtor.com page carries indicators as of May 2026, so both are months old and are used only as references. Realtor.com's sold median, up 41.67% in a year, is out of line with its flat listing median and is reported as printed and not relied on. The Census figures are five-year estimates for the postal area that the sheet lists for Dix Hills; the postal area has 65,747 residents and extends beyond Dix Hills, so its owner value is lower than the city sale figures. Only established data publishers and the Census are cited. Percent changes were taken as printed, and ratios, sums, fee figures and year-earlier values are this brief's arithmetic.

Conclusion

The record for Dix Hills shows a city level of about $1.1M to $1.5M depending on the source, homes that sell about 2% above list in under a month, more than half selling above the ask and a postal area of large midcentury owner-occupied houses. The useful number for an owner is a closed sale of a comparable house on the same streets, and a private buyer can price the house in front of them and close on the owner's schedule.
