$70M Hillsborough's Record 2026 Home Sale
2026 List Last Updated

Hillsborough is a strictly residential town in San Mateo County - no commercial zoning, no sidewalks in most areas, and among the largest average lot sizes on the Peninsula. It's also a market with virtually no agents physically headquartered inside town limits - nearly every agent who serves Hillsborough is based in adjacent Burlingame, San Mateo, or San Carlos, which is normal for this market. The directory below features 20 top-performing agents currently working Hillsborough, each with verified Zillow reviews and a consistent record of closed sales. Every profile links straight back to its original review source, so you can read the unedited feedback yourself.

How We Built This List

Agents qualify on three factors we could actually verify, sourced entirely from Zillow:

📋

Verified Transaction History

Every agent on this list has a documented track record of closed sales in and around Hillsborough - not just active listings or a polished bio.

⭐

Real Client Reviews

Agents qualify on the volume and rating of authentic, Zillow-verified client reviews - real buyers and sellers describing their own experience.

📍

Years of Local Market Specialization

We looked at how long each agent has actively specialized in the Hillsborough market specifically, over broader Bay Area experience.

Every agent below cleared the same bar for the Hillsborough market. This directory is refreshed periodically to reflect new sales activity and new reviews.

Hiring a Realtor in Hillsborough, California: FAQs

Who are the top realtors in Hillsborough, California right now?

There's no single best agent for everyone - the right fit depends on what you're looking for, whether that's sales volume, review rating and count, experience at your price point, or a specific neighborhood. Names that come up frequently in Hillsborough include Jenn Gilson, Casey Sternsmith and David Tapper, along with the other agents featured on this page. Each card links to that agent's original reviews so you can compare them yourself.

What is the most expensive home ever sold in Hillsborough?

As of our research (August 2026), the record is Villa de Verano at 3000 Ralston Avenue - a 12-acre estate that sold for $70,000,000 in 2026, confirmed by ABC7 News, the San Francisco Chronicle, and The Real Deal as the highest sale ever recorded in the town. Jenn Gilson was the listing agent.

How much does it cost to hire a realtor in Hillsborough, CA?

Most Hillsborough agents work on a commission basis, typically negotiated between 2% and 3% per side of the transaction. Since 2024's industry-wide changes to buyer-agent compensation rules, buyers now negotiate their agent's fee directly rather than assuming it's covered automatically - worth clarifying with any agent before signing a buyer's agreement.

What's the difference between a buyer's agent and a listing agent?

A listing agent represents the seller - pricing the home, marketing it, and negotiating the best possible sale price. A buyer's agent represents the purchaser, helping them find the right property and negotiate favorable terms.

How do I verify a realtor's reviews before hiring them in Hillsborough?

Every agent featured on this page links directly to their original Zillow profile, where you can read unedited client reviews straight from the source rather than a testimonial the agent selected themselves.
