The median home price in Preston Hollow, TX sits around $2.41 million as of mid-2026. If you’re buying a home in Preston Hollow, you’ve probably already noticed that buyers tend to narrow their search by postal boundaries – specific streets, specific property styles, specific zip codes.
Knowing the exact postal designations matters more than most buyers expect. It affects how you set up MLS alerts, how you estimate commute times, and what goes on your offer paperwork. Preston Hollow spans a few distinct zones within the broader Dallas-Fort Worth-Arlington metro area, and each one has its own feel and its own inventory mix.
The Primary Zip Codes Serving the Area
Preston Hollow runs primarily on three postal codes: 75225, 75230, and 75220. These cover the core residential blocks and local commercial centers that define the neighborhood, and you’ll see them on the majority of active listings.
The broader area also pulls in portions of 75209, 75229, 75234, 75240, and 75244 – zones that capture properties along the outer edges of the neighborhood boundaries. When you’re setting up automated MLS alerts, add those peripheral codes. You don’t want to miss a house because it landed on the wrong side of an invisible postal line.
Real estate agents use postal maps to help clients get a visual feel for where they actually want to be. A quick look at a boundary map shows how the three main codes cluster together to form the heart of the community.
Understanding the Neighborhood Boundaries
The traditional borders for Preston Hollow are Midway Road, Northwest Highway, Hillcrest Road, and Royal Lane. Homes within that rectangle fall into the most recognized sections of the community.
Worth mapping out those four streets before you tour. A property sitting just outside those lines might carry a different postal code while still giving you easy access to the same local amenities – which is either a plus or a minus depending on what you’re after.
Dallas County and the Broader Metro Market
All of Preston Hollow sits in Dallas County. That designation controls your property tax assessments and local government services, so when you’re building out your monthly carrying costs, you’re working from Dallas County rates.
The neighborhood is part of the Dallas-Fort Worth-Arlington, TX Metro area – often listed simply as the “Dallas Area” metro in demographic sources. Being centrally located within that regional hub is a real practical benefit for commuters.
When you’re filling out change-of-address forms or setting up utilities, you’ll list Dallas as your city and Dallas County as your jurisdiction. Nothing unusual there, but good to know before the paperwork starts.
Finding a Full Nine-Digit Postal Code
A standard five-digit code handles general mail fine, but official real estate documents often require the full ZIP+4 format – the nine-digit sequence that pinpoints a specific block, street segment, or large building.
You can find your exact nine-digit code by entering your new address into the official USPS lookup tool. Title companies and mortgage lenders use that expanded number to make sure all the legal paperwork routes to the correct property.
Sub-Areas and Local Landmarks
The postal codes here cover several distinct pockets: Old Preston Hollow, Preston Hollow East, Bluffview, North Dallas, and Northwest Dallas. Each one offers a different mix of lot sizes, architectural styles, and street layouts – they’re not interchangeable, and experienced buyers treat them that way.
Old Preston Hollow, typically associated with 75225, contains some of the most recognized estates in the region. If you’re looking for larger lots and historic properties, that’s where your search starts. The areas bleeding into Northwest Dallas offer a different inventory profile entirely.
The neighborhood is also home to notable properties like The Crespi/Hicks Estate – historically home to Italian count Pio Crespi and one of the most recognizable landmarks in the area. High-profile properties like that one shape overall values within their respective postal boundaries, and any agent who tells you otherwise isn’t paying attention to the comps.
Local Phone Area Codes
If you’re relocating from out of state and plan to set up a landline or a local business number, you’ll need the overlay codes assigned to the broader Dallas region. Telecommunications providers assign a local number when they set up home internet and phone packages.
Most buyers keep their existing mobile numbers. But if a local landline matters to you, ask your provider about the proper Dallas area code before you finalize your service setup.
Real Estate Prices and Market Activity
As of mid-2026, the median sale price across the Preston Hollow market is roughly $2.41 million. Homes are spending an average of 44 days on the market before going under contract – a steady pace, but well-priced homes aren’t sitting around.
Recent MLS data shows about 130 active listings, which works out to 4.5 months of supply. That’s a balanced market that tilts slightly toward sellers. Sellers are averaging about 96.5% of list price, and roughly 10% of recent sales closed above asking.
If you’re targeting 75225, 75230, or 75220 specifically, pull comparable sales carefully with your agent before you write an offer. The spread between list price and sale price is tight enough that coming in soft can cost you a house.
