Preston Hollow is a good place to buy a house in Dallas if you want acreage inside the city, and it is the one neighborhood in this batch where the median price tells you almost nothing useful. The median sale price was $1,295,000, up 8% year over year, over the trailing twelve months as of August 14, 2026 (Homes.com) — across a sale range running from $429,000 to $64 million.
Why is the median price misleading in Preston Hollow?
Roughly forty homes sell per month across that $429,000-to-$64-million range. A single $20 million closing moves the monthly median materially. That is why portals have published Preston Hollow "gains" of +39% to +68% in recent months — those are mix shifts, not appreciation. A month heavy on estate sales prints a huge median; the next month prints a small one. Nothing about the underlying market changed.
For the record, we discarded several widely-circulating figures for this neighborhood: Zillow's Home Value Index of $581,531 is a clear outlier against a $1.29 million median sale and should not be used, and Redfin returned four mutually inconsistent medians within a single session. The Homes.com figure above is the one we could date and defend.
Ask for the band, not the median. That is the practical instruction, and it is how The Agency Dallas frames the question of whether Preston Hollow is a good place to buy a house in Dallas: identify your band first, then look at comps only inside it.
What are the actual price bands in Preston Hollow?
By lot size (Grey Square, July 23, 2026):
- $1M–$3M — sub-acre lots
- $3M–$10M — one to three acres
- $10M–$50M+ — three or more acres
By sub-area:
- Old Preston Hollow — $3M to $20M+
- East Preston Hollow — $1.5M to $4M
- West Preston Hollow — $1M to $3.5M
- North Preston Hollow — $800K to $3M
Supporting figures: average price per square foot $517 (April 18, 2026), median days on market 63, against 43 a year prior — the market has slowed. New construction runs $300 to $600+ per square foot excluding land, which matters because land is most of the cost here.
Where is Preston Hollow, exactly?
Nowhere official. There is no city-adopted map of Preston Hollow. The area was platted in 1923 by Ira DeLoache on one-acre lots, incorporated as its own town in 1939, and annexed by Dallas in 1945. What people mean by "Preston Hollow" today is a loose region north of Northwest Highway centered on Preston Road, and different brokerages draw the line differently.
That ambiguity is a practical problem. Two listings can both claim Preston Hollow and sit in different school attendance zones, different price bands, and different sub-markets. Always work from the address, never the neighborhood label.
What is the school-district trap in Preston Hollow?
This is the single most expensive thing buyers get wrong here.
Most of Preston Hollow is Dallas ISD: Preston Hollow Elementary (GreatSchools 6/10), Franklin Middle School (5/10), and Hillcrest High School, which rated B in the TEA 2024-25 accountability cycle. Campus-level grades from the 2026 cycle are not yet published.
But a southeastern pocket of Preston Hollow falls inside Highland Park ISD — and that assignment carries a documented premium of roughly $200,000 to $500,000 or more on an otherwise comparable house.
The trap: the district line does not follow street boundaries. It runs through the middle of the neighborhood, and in places it splits blocks. Two houses on the same street can be in different districts. Never take the district from a listing description, a portal school panel, or a seller's claim. Verify the address with both districts in writing during the option period. A misread here is a six-figure error.
Private options are dense: St. Mark's School of Texas, The Hockaday School, Ursuline Academy, Greenhill School, Jesuit College Prep, Episcopal School of Dallas, and Parish Episcopal are all within reach — and a large share of Preston Hollow buyers are on that track, which is why the Dallas ISD ratings do not depress prices the way they otherwise might.
What does it cost to hold a house in Preston Hollow?
Property tax rates in the area run roughly 2.1% to 2.4%. On a $2 million home that is approximately $42,000 to $48,000 per year — before insurance, before maintenance on an older large house, before landscaping an acre.
Carrying cost is the number that surprises buyers moving here from outside Texas, where higher income tax offsets lower property tax. Model the annual carry, not just the mortgage payment.
How much of the original housing stock is left?
Preston Hollow was built as a one-acre ranch-house suburb. About half the original ranch-style homes have been torn down (Advocate, 2015 — the only hard figure available, and now dated). Teardown-and-rebuild remains the dominant activity, and unlike Lakewood and Kessler Park, there is no conservation district governing what replaces them.
That is the essential Preston Hollow trade. You get the largest lots inside the Dallas city limits and near-total freedom to build. You also get no protection against what happens on the lot next door.
Who should buy in Preston Hollow?
Good fit:
- Buyers who want one to three acres without leaving the city
- Anyone building custom who wants minimal design restriction
- Families on a private-school track, or buyers who have verified a Highland Park ISD address
Look elsewhere if:
- You want design protection for your block — Lakewood or Kessler Park have conservation districts, Preston Hollow does not
- A five-figure annual property tax bill does not fit the plan
- You want a defined neighborhood with agreed boundaries and consistent comps
At 63 days on market against 43 a year ago, buyers currently have more leverage in Preston Hollow than they did — which is the most actionable fact in this guide. When someone asks The Agency Dallas whether Preston Hollow is a good place to buy a house in Dallas, that leverage, the district line, and the annual carry are the three things we put on the table before any listing.
FAQ
How much is a house in Preston Hollow?
The median sale price was $1,295,000 over the trailing twelve months as of August 14, 2026, up 8% year over year (Homes.com). Sales range from $429,000 to $64 million, so the median is not a useful planning number. Work from the price band that matches your lot size.
Why do Preston Hollow price statistics vary so much?
Roughly forty homes sell per month across a range spanning more than $60 million. One estate closing can swing the monthly median dramatically, which is why portals have reported +39% to +68% "gains." Those reflect changes in what sold, not appreciation.
Is Preston Hollow in Highland Park ISD?
Mostly no — most of Preston Hollow is Dallas ISD. A southeastern pocket is Highland Park ISD, and that assignment carries a $200,000 to $500,000+ premium. The boundary does not follow streets and can split a block, so verify your exact address in writing with both districts.
What are property taxes in Preston Hollow?
Rates run roughly 2.1% to 2.4%, so a $2 million home carries approximately $42,000 to $48,000 annually. Buyers relocating from higher-income-tax states routinely underestimate this. Model the full annual carrying cost including insurance and maintenance on an older large home.
Is Preston Hollow a good investment?
Land inside the city limits is the durable asset, and about half the original ranch homes have already been replaced. The offsetting factors are no conservation district protecting neighboring lots, high carrying cost, and comps that are thin at every level above $3 million.
