The agents and brokerages that sell the most expensive homes in Preston Hollow are the ones with a record of closed estate sales in the neighborhood. A logo, a billboard or a list of active listings doesn't tell you that. The best way to find out is to look at closed MLS sales above $5 million in Preston Hollow over the last two to three years and see who represented the sellers and the buyers. Across Dallas-Fort Worth, sales at that level are rare: 15 homes listed above $10 million sold in the region in 2025, according to a Compass ultra-luxury report cited by The Real Deal.
At The Agency Dallas, we work with estate sellers and buyers across Preston Hollow. This guide explains how to find out who is actually doing that business and what to ask them.
How do I find out who sells the most expensive homes in Preston Hollow?
Rankings and advertising are a starting point, but closed sales are the proof. Here is how to build a clear picture:
- Ask for closed sales above your price point. Request a list of Preston Hollow closings above $3 million, $5 million or $10 million over the last 24 to 36 months, with the listing and buyer's agent for each.
- Separate listings from closings. An agent with several expensive active listings has not necessarily sold any of them.
- Check both sides. Agents who represent buyers at the top of the market know where demand is coming from. That is valuable to a seller.
- Account for private sales. Some of the most expensive Preston Hollow transactions never hit the public portals. Ask agents directly which off-market sales they handled, and how they can document them.
- Confirm with public records. Dallas Central Appraisal District records and deed filings can confirm that a property changed hands, even when the price is not disclosed.
Why are Preston Hollow's top sales so hard to track?
Preston Hollow is large and varied. The most expensive estates cluster on a handful of streets, often on lots of two acres or more, while other parts of the neighborhood trade at a fraction of those prices. A few factors make the top end opaque:
- Texas is a non-disclosure state, so sale prices are not published in public records.
- Many ultra-luxury sellers choose private or off-market sales for privacy.
- Sales volume is low. A handful of transactions can swing any annual ranking.
- Team totals are often reported as one agent's results, which can make comparisons misleading.

What should a Preston Hollow estate seller ask an agent?
Once you have a short list, ask each agent the same questions:
- Which Preston Hollow homes above my price point have you sold, and when?
- How did you price them, and how close did they close to list price?
- How long did each one take to sell?
- Who were the buyers, in general terms: local move-up, relocation, out of state or international?
- Will you market my home publicly, privately, or start private and go public?
- What will the marketing campaign include, in writing?

How long do the most expensive Preston Hollow homes take to sell?
Estate homes take longer than typical Dallas homes because the buyer pool is small. A well-priced estate can sell in a few months, while an overpriced one can sit for a year or more. Our guide on how long estate homes take to sell in Dallas covers the timeline in detail.
Does the brokerage matter at the top of the market?
At this price level, the agent matters most, but the brokerage shapes what the agent can do. Look for in-house marketing support, leadership that reviews complex contracts, and a network that reaches buyers outside Texas. Many Preston Hollow estate buyers come from out of state, so reach beyond the local MLS matters.
What separates a good estate agent from a great one in Preston Hollow?
Closed sales get an agent on your short list. A few other qualities usually decide who sells the home well:
- Honest pricing. The best estate agents will tell you when your expectations are above the market, and show you the sales that prove it.
- Buyer knowledge. They know which buyers are actively looking at this level, including relocating executives and out-of-state families, and what those buyers want.
- Preparation. They guide sellers on repairs, staging and documentation before launch, so the home shows well and inspections go smoothly.
- Negotiation. At this price, a few percentage points in negotiation can mean hundreds of thousands of dollars. Ask how the agent handled their last few estate negotiations.
- Communication. Estate sales can take months. Agree on how often you will hear about showings, feedback and market changes.
Sellers who interview with these points in mind usually end up with a clearer plan and fewer surprises once the home is on the market.

Frequently asked questions
Who sells the most expensive homes in Preston Hollow?
The agents with the most closed Preston Hollow sales above $5 million over the last few years. Ask for documented closings, both listing and buyer side, and confirm them with MLS records. Because some top sales are private, ask agents directly about off-market transactions they handled and how they can verify them.
How many homes sell for more than $10 million in Dallas?
Very few. A Compass ultra-luxury report cited by The Real Deal counted 15 homes listed above $10 million that sold in Dallas-Fort Worth in 2025, up from 13 in 2024. Preston Hollow and Highland Park account for a large share of sales at that level.
Are Preston Hollow sale prices public?
No. Texas is a non-disclosure state, so sale prices are not recorded in public records. Prices are available to agents through the MLS when a sale is reported there. Private sales may not be reported at all, which is why top-end rankings can be incomplete.
Should I sell my Preston Hollow estate off market?
It depends on your priorities. A private sale protects privacy and can work when an agent already knows qualified buyers. A public launch usually reaches more buyers and creates competition. Some sellers start privately for a few weeks, then go public if needed.
What questions should I ask a Preston Hollow listing agent?
Ask which homes above your price point they have sold, how close those sales came to list price, how long they took, where the buyers came from, and exactly what marketing they will provide. Ask for answers in writing so you can compare agents fairly.
