Why Do the Redfin and Realtor.com Sold Medians for Galleria and Tanglewood Differ So Widely? Reading the Large Apartment Buildings, the Renters and the Wide Margins of Error

Why do the Galleria and Tanglewood price figures disagree?

The two pages disagree by a wide margin, and the gap is too large to be a matter of timing. Redfin's median of $857,256, up 45.9%, implies about $587,564 a year earlier. Realtor.com's sold median of $494,900, up 6.18% in a year, implies about $466,095 a year earlier. The Redfin figure is 73.2% above the Realtor.com sold median and 71.6% above the Realtor.com listing median, though the pages cover different months.

The likeliest explanation is that the pages count different sets of homes. The postal area holds 2,914 detached houses and 11,920 units in buildings of five or more, and a median of all sales moves with the mix. If Redfin's three months included more houses and Realtor.com's September month included more condominium sales, the two could diverge in this way. That is an inference and not something either page states, and it should be read as a reason for caution and not as a finding.

Realtor.com's sold median is also volatile. At $494,900, down 14.40% in a month, it implies about $578,154 the month before. The listing median of $499,500, up 0.20% in a month, implies about $498,503 the month before, and up 11.11% in a year, implies about $449,554 a year earlier. The listing median is the steadier of the two. Redfin's $857,256 sold median, up 45.9% in a year, is also out of line with its own per-foot price, which is up 14.5%.

Per-foot prices narrow the gap. Redfin's $287, up 14.5% in a year, implies about $251 a year earlier. Realtor.com's $261, down 2.13% in a year, implies about $267, and down 0.39% in a month implies about $262. Redfin's figure is 10.0% above the Realtor.com figure. Per-foot prices show less spread than the medians, and they point to a market that is flat or slightly up, not one that jumped forty-five percent.

The Census median owner value of $860,900, plus or minus $103,606, is close to the Redfin sold median, and the Redfin figure is 0.4% below it. The Realtor.com listing median is 42.0% below the Census value. The Census value has a wide margin of error, about 12% of the estimate, and covers only the 4,326 owner-occupied homes, so the owners it describes may live in larger homes than the typical unit in the postal area. The Census value is 9.2 times the median household income of $93,499, plus or minus $6,551.

Owners comparing a listing with a direct offer should keep two questions apart. The first is what the typical home in the postal area sells for, which the pages answer with figures from about $495,000 to $860,000 depending on the source and the measure. The second is what a particular home would bring, which depends on its type, size, age, condition and lot, and only the closed sales of the most similar homes can answer it.

How long do Galleria and Tanglewood homes wait, and what do sellers get against asking?

The pages put the wait at about one to two months. Realtor.com shows a median of 63 days on the market, down 0.80% in a month, which implies about 64 days the month before, and down 6.06% in a year, which implies about 67 days a year earlier. Redfin's page shows a median of 44 days against 60 a year before, and says the average home goes pending in around 73 days and hot homes in around 19 days. The median and the average measure different things, and the average includes the homes that wait longest.

Sales settle below asking. Realtor.com puts the sale-to-list ratio at 97%, and says homes sold for 3.23% below the asking price on average in September 2026. Redfin's ratio is 96.7%, up 1.6 points, which implies about 95.1% a year before, and it says the average home sells for about 4% below list and hot homes for about 1% below. Homes sold above list were 8.3% of sales, up 2.0 points, which implies about 6.3% a year before. Homes with price drops were 34.5%, up 0.3 points, which implies about 34.2% a year before.

The sources disagree about who has the advantage. Realtor.com calls the area a cool market and a buyer's market, in which supply is greater than demand. Redfin's compete score is 33 of 100, which it calls somewhat competitive, with some homes getting multiple offers. Realtor.com shows 252 active listings, down 0.38% on the year, which implies about 253 a year earlier, and down 4.35% on the month, which implies about 263. Supply is steady, and Redfin shows 74 homes sold in June, down 6.3% from 79, which agrees with the arithmetic.

Rentals fell sharply. Realtor.com shows 233 rental properties, unchanged on the month and down 55.13% on the year, which implies about 519 a year earlier. A fall of that size is flagged as a possible change in how the page counts listings and not as a market fact. The median rent of $1,900 is up 1.82% on the month, which implies about $1,866, and down 2.56% on the year, which implies about $1,950. The Census median gross rent of $1,840, plus or minus $53, is 3.3% below the Realtor.com figure.

A market with sales at about 3% to 4% below list, and about a third of homes cutting their price, rewards a price set close to recent sales of comparable homes. It punishes a price set well above them, and the figure that matters is the one that comparable homes closed at.

A wait of one to two months is an average, and the spread around it matters to a seller with a fixed date. Some homes sell in weeks, and others sit for several months and then cut their price. The pages report medians and not the spread, so an owner who needs to close by a given date can ask for the days on market of homes sold in the last few months, which gives a better guide to the risk of a long wait than the postal area median.

Who lives in Galleria and Tanglewood, and how heavy is the cost of housing?

Renters are two thirds of households. Of 12,929 occupied homes, 4,326 are owner-occupied, 33.5%, and 8,603 are renter-occupied, 66.5%. Of 15,768 units, 2,839 are vacant, 18.0%, including 1,552 for rent, 165 for sale only, 392 rented and not yet occupied, 178 sold and not yet occupied, 193 for seasonal, recreational or occasional use, and 359 other vacant units. Vacant units for rent alone are 9.8% of all units.

Owners are mixed in tenure. Of 4,326 owner households, 183 moved in during 2023 or later, 4.2%, 490 between 2020 and 2022, 11.3%, 1,925 in the 2010s, 44.5%, 873 in the 2000s, 20.2%, 529 in the 1990s, 12.2%, and 326 before 1990, 7.5%. Owners who moved in before 2010 are 39.9%. Renters are newer: of 8,603, 1,889 moved in during 2023 or later, 22.0%, 3,580 between 2020 and 2022, 41.6%, 2,938 in the 2010s, 34.2%, and 196 earlier, 2.3%.

The population is working-age. Of 22,877 people counted, 2,333 are under 18, 10.2%, 1,641 are 18 to 24, 7.2%, 4,628 are 25 to 34, 20.2%, 3,421 are 35 to 44, 15.0%, 5,191 are 45 to 64, 22.7%, and 5,663 are 65 or older, 24.8%. Owner homes are mixed in size: of 4,326, 1,307 have three bedrooms, 30.2%, 1,018 have four, 23.5%, 943 have two, 21.8%, 548 have five or more, 475 have one and 35 have none. Renter homes lean to one bedroom: of 8,603, 4,181 have one, 48.6%, 3,185 have two, 37.0%, 772 have none, 284 have three, 118 have five or more and 63 have four.

Owners with a mortgage carry a real burden. Of 4,326 owners, 1,972 have a mortgage, 45.6%, and 2,354 do not, 54.4%. Among the 1,951 mortgage holders with a computed figure, 840 spent 30% or more of income on housing costs, 43.1%, and 512 spent 50% or more, 26.2%. Among the 2,301 owners without a mortgage and with a computed figure, 587 spent 30% or more, 25.5%, and 396 spent 50% or more, 17.2%. About one owner in six without a mortgage above the 50% mark is a notable figure, and the table does not say why. It is probably related to taxes, insurance and association fees, but that is an inference.

Renters carry a heavy burden too. Of 8,603 renters, 8,288 with a computed figure, 3,986 spent 30% or more of income on rent, 48.1%, and 2,132 spent 50% or more, 25.7%. About one renter household in two is above the 30% mark, and about one in four is above 50%. An owner who rents out a home is dealing with tenants who are often stretched, which matters to anyone comparing a rental income with a sale.

How old is the Galleria and Tanglewood stock, and how many units are in large buildings?

The stock is mixed in age, with a recent peak. Of 15,768 units, 131, or 0.8%, were built before 1940, 9, or 0.1%, in the 1940s, 771, or 4.9%, in the 1950s, 2,018, or 12.8%, in the 1960s, 1,547, or 9.8%, in the 1970s, and 1,901, or 12.1%, in the 1980s. After that, 1,738, or 11.0%, were built in the 1990s, 3,715, or 23.6%, in the 2000s, 3,753, or 23.8%, in the 2010s and 185, or 1.2%, in 2020 or later. The 2000s and 2010s together hold 7,468, or 47.4%, and homes built before 1980 total 4,476, or 28.4%.

The building types are heavily weighted to large buildings. Of 15,768 units, 2,914 are detached, 18.5%, 599 are attached, 3.8%, 138 are in two-unit buildings, 147 are in buildings of three or four units, 305 in buildings of 5 to 9, 668 in buildings of 10 to 19, 1,239 in buildings of 20 to 49, 9,708 in buildings of 50 or more, and 50 are mobile homes. Buildings of five or more units hold 11,920, or 75.6%, and buildings of 50 or more alone hold 61.6%.

For a seller of a house or a townhome, this means the postal area medians are mostly set by other kinds of homes. A house is a different product from a unit in a large building, with its own lot, its own roof and its own buyers. The apartment and condominium counts also move the sold median from month to month, because each building sells in different numbers. A fair price for a house comes from the sales of houses nearby, and not from the postal area figure.

A home built before 1990 is now thirty-five years old or more. Roofs, windows, heating and cooling systems, wiring and plumbing may all be near the end of their lives unless they have been replaced, and a buyer's inspector will note each item. The sources do not say which items apply to any home. These are general points and not figures from the sources.

A seller who would rather not have an inspector's list negotiated can choose a private sale, in which a buyer buys the home as it stands. That is the fifth benefit of Maison Off-Market, avoiding inspections and repairs, and it is not a claim that a private sale always yields a higher price. Readers comparing markets can also read the Highland Village brief and the Memorial Villages brief.

What should a Galleria or Tanglewood owner ask before choosing a listing or a private sale?

Five questions are worth asking. Is my price based on closed sales of homes like mine, of the same type, size and age, and not on one median? How many weeks might a listing take, and how far below the first ask are sales settling? What will inspections and repairs cost me on a home of this age? Who will see the home during showings, and who will hear about the sale? And what date do I need to close, given where I plan to live next?

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. At 3%, those sales cost $13,500, $21,750 and $36,000, and at 5% they cost $22,500, $36,250 and $60,000. At the Realtor.com listing median of $499,500, 1% is $4,995 and 5% is $24,975. Maison Off-Market does not charge commissions or closing costs.

A private sale has no showings and no neighbors talking about it, which is the first benefit. The second benefit is a closing date the owner can set, which gives time to find a new home. The third is no commission costs, the fourth is no closing costs and the fifth is avoiding inspections and repairs. In a market where sales settle a few points below list and about a third of homes cut their price, an owner may value a sale that does not depend on showings.

A fair comparison puts the commission, the closing costs, the repairs a buyer may ask for, the weeks of carrying costs and the preparation for showings next to the privacy given up. It also puts a realistic listing result, and not the best case, next to a direct offer. With a wide gap between the published medians, a realistic listing result for a particular home is hard to read from the data, and a direct offer gives a number to compare.

Maison Off-Market buys luxury homes and estates directly from their owners and speaks only to sellers. It does not say that every private sale beats a listing. An owner who wants to see what a direct purchase would look like, with no public listing and no showings, can use the contact form below and ask for an offer before deciding.

Methodology and limitations

Each page's date, title and place were read before use. The Redfin page covers the three months ending June 2026 and is the older of the two, and the Realtor.com page has key indicators as of September 2026 and is the newest. The two sold medians differ by about $362,000, and the Redfin figure, up 45.9% in a year, does not fit its own per-foot price, which is up 14.5%. Both are flagged as likely to reflect the mix of homes sold. The Realtor.com sold median, down 14.40% in a month, and the drop of 55.13% in rental listings are flagged as volatile. Realtor.com calls the area a buyer's market, while Redfin calls it somewhat competitive. No Zillow postal-area page was found, so no Zillow figure is used. The Realtor.com neighborhood tables list other places and were not relied on. The Census figures are five-year survey estimates with margins of error, wide for owner value. Earlier values are computed from published percentages and are approximate. No figure here is a forecast.

Conclusion

The record for Galleria and Tanglewood, as far as the pages allow, is a market of large apartment buildings where two published sold medians differ by about $362,000, where sales settle a few points below list, where a third of homes cut their price, and where two thirds of households rent. For an owner, the practical step is to ask for the closed sales of comparable homes of the same type, compare the cost and risk of a listing with a direct offer, and decide how much of the showing, inspection and timing risk to carry.
