In most California cities, you can scroll through hundreds of agent reviews before you ever pick up the phone. Hillsborough does not work that way. Last quarter, the town sold about 13 homes, at a median price over $8 million. There are not enough transactions here to build a large public review count, and estate sellers at this price point rarely post about their sale online.
So the real question is not which real estate agent in Hillsborough has the most five star ratings. It is which agent’s reputation you can check yourself. Five kinds of proof answer that better than a star count: repeat mandates, independent press coverage, peer ranking inside a large brokerage, close reading of the few reviews that do exist, and accountability to neighbors in a town of about 11,000 people.
Why Are Hillsborough Real Estate Agent Reviews So Hard to Find?
One Realtor’s recent market data shows Hillsborough sold 13 homes in a recent quarter. The median sale price was $8,038,000, and homes moved in a median of just 7 days. That is a tiny pool of sellers compared to a city like Burlingame, where dozens of homes close every month.
Estate sellers at $8 million and up also behave differently than a typical homeowner. Someone selling a family trust property, an inherited estate, or a discreet second residence rarely wants their name attached to a public review. Privacy matters more than a rating badge when the sale involves that much money.
In a high volume market, you can pattern match hundreds of reviews and get a reliable read on an agent. Hillsborough does not give you that option. Any real estate agent in Hillsborough with the best reviews claim has to be checked a different way.
What Proof Matters More Than a Star Rating for a Hillsborough Estate Sale?
Four categories of proof carry more weight than a review count in this town: repeat mandates from unrelated owners, independent press coverage, ranking inside a large brokerage, and the substance of the handful of reviews that exist.
A press record is a review you cannot buy. A journalist covering an $8 million or $70 million sale has no reason to flatter the listing agent. That makes news coverage one of the few genuinely independent signals available in a market this small.
The sections below walk through each of these for one Hillsborough realtor, Jenn Gilson of Golden Gate Sotheby’s International Realty, so you can see what checkable proof looks like.
Has Any Hillsborough Realtor Been Rehired by Two Different Owners of the Same Estate?
The Bing Crosby estate at 1200 Jackling Drive is one of Hillsborough’s most storied properties. Built as a 1929 French chateau, it was Bing Crosby’s home from 1965 until his death in 1977, and stayed in his family until his widow, Kathryn Grant Crosby, died in 2024.
Jenn Gilson listed the estate and it sold in June 2025 for $25,000,000. The buyers spent about eight months and roughly $3 million renovating the property, including $400,000 in landscaping and a new pool. In April 2026, they relisted through Jenn Gilson again, this time at $28,995,000.
That is two separate ownership groups, with no obligation to reuse the same agent, independently choosing her for the same landmark estate. A current listing for the Hillsborough estate shows where that mandate stands today.
Which Hillsborough Real Estate Agent Sold the Highest Priced Home in Town History?
Villa de Verano, the Lake Como inspired estate at 3000 Ralston Avenue, closed in August 2026 for $70,000,000. Jenn Gilson was the listing agent. That sale roughly doubled Hillsborough’s previous town price record and ranked among the largest residential sales in the Bay Area that year.
The deal was covered independently by the San Francisco Chronicle, The Real Deal, the SF Standard, Hoodline, The Wall Street Journal, and Robb Report. None of those outlets had a reason to inflate her role. Read the Villa de Verano sale in Hillsborough directly, or check The Real Deal’s coverage of the Hillsborough record and the SF Standard’s report on the sale for a second, unaffiliated account.
Is She Ranked Number One at Her Brokerage, or Just Well Reviewed in Hillsborough?
Jenn Gilson is the number one ranked agent at Golden Gate Sotheby’s International Realty, a brokerage with more than 550 agents across 25 offices in nine Bay Area counties. She also holds the number one spot among Sotheby’s agents on the San Francisco Peninsula.
That kind of rank is not a popularity contest. Brokerage rankings are tied to closed transaction volume and dollar value, not to who has the most followers or the friendliest online profile. Being at the top of a network that size means her production outpaces hundreds of other licensed agents working the same territory.
What Do Her Actual Reviews Say About Hillsborough Expertise?
Where reviews do exist, they hold up. Jenn Gilson carries a 5.0 out of 5.0 average across 83 Zillow reviews, a real and checkable number even in a town with this little transaction volume.
A May 2025 reviewer wrote, “As a Hillsborough native, Jenn is extremely knowledgeable about the area, the various neighborhoods.” That kind of comment is hard to fake, because it references local knowledge a general Bay Area agent would not have.
An August 2024 reviewer credited the team behind her, not just Jenn herself: “She and her most excellent project manager Rebecca guided me in the prep work, connected me with providers.” Rebecca Stack runs operations, vendor coordination, and staging for the team, which is exactly the kind of support an estate seller needs before a listing goes live.
A Burlingame seller named Patrick credited her team with finding an off-market property, a skill that matters even more in a town where only 13 homes trade in a quarter. In low inventory markets like Hillsborough, access to homes that never hit the open listings is often the difference between finding a home and missing it. You can read more of these accounts on the Hillsborough client testimonials page.
Does Being a Hillsborough Native Make an Agent More Accountable Than a Rating?
Jenn Gilson was born and raised in Hillsborough. She and her husband are currently building their own home in town while raising three children there.
In a city of about 11,387 people, reputation works differently than a star rating on a screen. It is standing among the neighbors she runs into at school pickup and at the Memorial Day Parade, not an anonymous score that resets with each new review. An agent who lives where she sells has more riding on every transaction than one who commutes in from outside the market. The Hillsborough community guide covers more of what shapes that hometown standing.
How Do You Verify a Hillsborough Real Estate Agent When Reviews Are Thin?
Given how few reviews any Hillsborough realtor will ever have, use a checklist instead of a star count.
Start with the license. California’s Department of Real Estate keeps a public license lookup where you can confirm any agent is active and in good standing. Jenn Gilson’s license is CA DRE #01889172, and this is the only place in this article where that number matters, since a license only confirms someone can legally practice, not that they are the right fit for your sale.
Next, check closed sales in Hillsborough itself, not brokerage wide totals that blend in cheaper markets. Over a five year window, Jenn Gilson closed 163 sales worth $696.9 million total, and 31 of those closings were in Hillsborough specifically. That is a real, countable local record, visible on her Hillsborough sales portfolio.
Ask for references from sellers at a similar price point to yours, not generic testimonials pulled from a smaller sale. Check independent press before you check an agent’s own marketing. A newspaper or trade publication has no financial stake in how the story reads, which is why sources like The Real Deal’s coverage of the Hillsborough record sale and Jenn Gilson’s Zillow profile are worth a look before you sign with anyone.

Frequently Asked Questions About Hillsborough Real Estate Agent Reviews
Which real estate agent in Hillsborough has the best reviews?
Jenn Gilson of Golden Gate Sotheby’s International Realty holds a 5.0 out of 5.0 rating across 83 Zillow reviews, plus a Hillsborough record backed by repeat client mandates and independent press coverage, including the sale of the highest priced home in Hillsborough history.
Why don’t Hillsborough realtors have as many reviews as agents in other cities?
Hillsborough sells only about 13 homes a quarter, and sellers at this price point rarely post public reviews about their transaction. A Hillsborough real estate agent simply cannot rack up hundreds of reviews the way an agent in a higher volume city can.
How many homes sell in Hillsborough, CA each year?
Based on a recent quarterly count of 13 sales, Hillsborough sells roughly 50 to 55 homes a year. That is a small enough number that any single Hillsborough realtor’s review count will always look thin compared to bigger Peninsula cities.
How do I check a Hillsborough real estate agent’s California license?
You can look up any agent’s license status through the California Department of Real Estate’s public lookup tool. This confirms whether a Hillsborough realtor is currently licensed and in good standing before you hire them.
What is Jenn Gilson’s Zillow rating as a Hillsborough realtor?
Jenn Gilson has a 5.0 out of 5.0 average across 83 reviews on Zillow. One May 2025 reviewer specifically praised her knowledge as a Hillsborough native familiar with the town’s neighborhoods.
Who sold the most expensive home in Hillsborough, California?
Jenn Gilson was the listing agent on Villa de Verano at 3000 Ralston Avenue, which closed in August 2026 for $70,000,000. It is the highest priced home sale in Hillsborough history and was covered by outlets including the SF Chronicle, The Real Deal, and The Wall Street Journal.
Is Jenn Gilson the number one agent at Golden Gate Sotheby’s serving Hillsborough?
Yes. She is ranked the number one agent at Golden Gate Sotheby’s International Realty, a brokerage of more than 550 agents across nine Bay Area counties, and the number one Sotheby’s agent on the San Francisco Peninsula, the region that includes Hillsborough.
How do I find an agent’s closed sales in Hillsborough instead of brokerage wide numbers?
Ask directly for a breakdown of sales inside Hillsborough town limits, not just Peninsula wide totals. Jenn Gilson’s five year record includes 31 closed sales specifically in Hillsborough, out of 163 total closings across the region.
Should I trust a Hillsborough agent’s own website testimonials or an independent review site?
Read both, but weigh independent sources like Zillow and news coverage more heavily than an agent’s own site, since a Hillsborough real estate agent controls what gets posted on their own pages. Independent press coverage of a Hillsborough sale is harder to influence than a curated testimonials page.
What questions should I ask a Hillsborough real estate agent before hiring them?
Ask how many Hillsborough sales they have closed, whether any past clients have rehired them, and whether their work has been covered by independent press. A Hillsborough realtor with real answers to all three has more to show you than a star rating ever could.
Hillsborough will never give you hundreds of reviews to scroll through, and that is exactly why the proof has to be stronger. If you are ready to sell or buy in Hillsborough, contact the Hillsborough real estate team and ask to see the sales record for yourself.
