Nineteen Preston Hollow area homes priced at $5 million or more closed through the MLS in the 12 months ending October 31, 2026, at a median of $6,750,000 and a median of 20 days on market, according to NTREIS data pulled November 7, 2026. Most of those estates sold quickly, but a meaningful minority sat for three months or longer, and the difference usually came down to pricing against the right comparables.
The Agency Dallas, an independently owned and operated brokerage serving North Texas, reviewed every MLS closing at $5 million or more in the City of Dallas portions of the 75225, 75229 and 75230 ZIP codes, which cover most of Preston Hollow. Here is what sold, how fast, and what it means for an estate owner thinking about selling.
What did Preston Hollow estates over $5 million sell for?
Between November 1, 2025 and October 31, 2026, the 19 closings looked like this:
- Median price: $6,750,000, with sales ranging from $5,000,000 to $9,500,000.
- Median home size: about 8,153 square feet.
- Median price per square foot: about $782.
- Median lot: about 0.81 acres.
- Median days on market: 20.
These figures cover MLS-recorded sales only. Some estates in this price range trade privately, so the true number of sales is likely higher than what the MLS shows.
How long do $5 million homes take to sell in Preston Hollow?
The median was 20 days, but the spread is the more useful number for a seller:
- 13 of the 19 sold in 30 days or less.
- 1 took about 51 days.
- 5 took more than 90 days, with the longest at 207 days.
In other words, roughly two out of three estates found a buyer within a month, and about one in four took a season or longer. At this price, there are fewer buyers and fewer true comparables, so a listing that misses the market tends to wait rather than adjust quickly.
Why do some estates sell in days while others sit?
When we review slow sales at the top of the market, a few causes repeat:
- Pricing from the wrong comparables. A sale three streets away on a different lot size can mislead by millions.
- Lot and setting. Frontage, tree canopy, privacy and street position drive value here as much as the house.
- Condition and age of finishes. Buyers at this level compare against new construction.
- Launch strategy. Estates that launch with complete photography, floor plans and disclosures give buyers what they need to act.
- Timing. Relocating executives and families often buy on school and work calendars.
How should a Preston Hollow estate be priced?
The Agency Dallas prices estates by building a narrow set of comparables rather than relying on area medians:
- Closed sales within a similar lot size and street type.
- Homes of similar age and construction quality.
- Adjustments for pools, guest houses, motor courts and outdoor living.
- Active and pending competition at the same price, since buyers compare what is available today.
With a median of about $782 per square foot, a few hundred square feet or a better lot can move value substantially, so this level of detail matters. For buyer-side due diligence on lots and foundations, see buying in Preston Hollow, and for a neighborhood comparison see Preston Hollow or Highland Park.
What should an estate seller prepare?
- A current survey, plus permits and plans for any additions or major work.
- Records for roof, HVAC, foundation and drainage.
- A clear privacy plan for showings, including qualified-buyer requirements.
- Professional photography, video and floor plans ready at launch.

What do the numbers not tell a seller?
Nineteen sales is a small set, and medians at this level can shift with just two or three closings. A few limits are worth keeping in mind when reading the data:
- Private sales are missing. Estates sold without an MLS listing do not appear, and those are often among the largest transactions.
- Days on market can reset. A home withdrawn and relisted may show a shorter count than its true time for sale.
- Square footage varies by source. Appraisal district, plans and listing figures do not always match, which affects price per square foot.
- Land drives a large share of value. Two homes of similar size can differ by millions because of lot size, frontage and street.
For those reasons, we treat the area median as a starting point and build the actual price from a handful of closely matched sales, then test it against the homes a buyer could choose instead today. That last step matters most at the top of the market, where a buyer may be weighing only three or four true alternatives.
Is now a reasonable time to sell a Preston Hollow estate?
The data points to steady demand for well-priced estates: most of the homes above $5 million that sold over the past year went under contract within a month. Sellers who price from close comparables and launch with complete materials are positioned to be in that group. Sellers who need top-of-range pricing should plan for a longer timeline and budget for carrying costs during a season on the market.

What is the median price of a Preston Hollow estate over $5 million?
The median was $6,750,000 across those 19 sales, with prices from $5,000,000 to $9,500,000. The median home had about 8,153 square feet on about 0.81 acres and sold for about $782 per square foot. Individual values vary widely with lot, street and condition.
How long does a $5 million home take to sell in Preston Hollow?
The median was 20 days on market over the past year. Thirteen of 19 estates sold within 30 days, while five took more than 90 days and the longest took 207. Accurate pricing against close comparables and a complete launch are the biggest factors in which group a home falls into.
What ZIP codes cover Preston Hollow?
Preston Hollow falls mostly within 75225, 75229 and 75230 in the City of Dallas. Those ZIP codes also include areas outside the traditional neighborhood boundaries, and 75225 includes part of University Park, so we limited this analysis to City of Dallas addresses within them.
Do all Preston Hollow estates sell on the MLS?
No. Some estates sell privately without appearing in MLS records, so MLS data understates total activity at the top of the market. Sellers considering a private sale should weigh privacy against the wider exposure and price discovery that a full MLS launch can bring.
