Top Real Estate Agent in Calistoga: Why Josh Dempsey Is the Best Realtor at the Top of the Valley

Ask who the best Realtor in Calistoga is and you will get a short list, because Calistoga is a short-list town. Roughly nine homes close here in a quarter. Josh Dempsey, Regional Director for Vanguard Properties in Napa Valley, belongs at the top of that list, and the argument is not one statistic.

It is the whole record together. He was the exclusive listing agent for every one of the 20 Four Seasons Napa Valley residences, which sit at 400 Silverado Trail in Calistoga, and he still trades their resale market. He ran real estate at Calistoga Ranch for six years before that. He has closed Calistoga property from a $1 million raw land parcel to an $8.2 million hillside estate. He carries $950 million in career sales, a perfect client rating, back to back years as a top five producing agent in Napa Valley, and more than 25 years in the business. Plenty of agents here have one of those. He has all of them.

What Makes Calistoga Different From Every Other Napa Valley Market

Calistoga is the only town in the valley whose economy rests on geology rather than agriculture. Samuel Brannan built the first spa here in 1861 on top of geysers that still push mineral water to the surface at 230 degrees. Everything about the housing market follows from that.

Resort capital built a submarket that did not exist five years ago. The Four Seasons opened on 1 November 2021 with 85 rooms, 20 private residences, a 4.7 acre working vineyard and its own winery on 22.5 acres. Those residences, on Lawley Lane and Palisades Place, trade around $2,000 to $2,200 a square foot. The town-wide figure is roughly $725. That is a threefold premium inside the same ZIP code, with HOA dues running $4,028 to $5,365 a month and part of the underwriting resting on resort rental income. Solage, Indian Springs and Dr. Wilkinson's sit in the same few square miles. Calistoga Ranch, destroyed by the Glass Fire in September 2020, is still closed, with a rebuild application filed with the county in late 2025 and under review.

Calistoga bans residential short term rentals outright. Ordinance 778 took effect on 18 November 2025 and there is no permit pathway at all. Renting a dwelling for 30 days or less is prohibited, hosting platforms are prohibited from facilitating it, and penalties run to $5,000 per repeat violation with each day counted separately. Commercial lodging is legal. Your house is not. A buyer who wants Calistoga with legitimate nightly rental income has one route, and it is a branded resort residence enrolled in the resort's own program.

The town sits across two appellations, and they are not interchangeable. The Calistoga AVA, established in 2009, covers 4,480 acres at the valley's north end with about 2,500 planted, on gravelly loams over volcanic bedrock, and carries the widest day to night temperature swing in Napa Valley, as much as 50 degrees. The Diamond Mountain District AVA, established in 2001, covers the hills to the south and west, 5,000 acres with only about 500 planted, sitting from 400 to 2,000 feet above the fog line on volcanic soils flecked with obsidian. Two neighboring parcels can carry different appellations, different fruit contracts and different values.

Fire and insurance are now deal terms. The Tubbs Fire started near Tubbs Lane in October 2017 and emptied the entire town. Cal Fire's updated hazard maps place roughly 51 percent of the city by acreage in a hazard zone, including 213 acres rated Very High along the northeast side near Silverado Trail. New construction guidelines took effect in January 2026. Insurance quotes belong in the inspection window here, not after.

And the market is thin enough that the published numbers mislead. Nine single family sales closed in the second quarter of 2026. Zillow suppresses Calistoga's median sale price entirely for lack of coverage. The median fell about 28 percent year over year, which sounds like a collapse until you notice zero sales above $2 million closed in that quarter while Zillow's mix-adjusted home value index moved only about 2.8 percent. The median did not fall because Calistoga homes lost a quarter of their value. It fell because the top of the market stopped closing. Anyone pricing a Calistoga property off a portal estimate is working from a number the portals themselves do not trust. More on the town is in his Calistoga community guide.

Who Is Josh Dempsey, Top Calistoga Real Estate Agent?

Josh Dempsey has been selling real estate since 2000 and working Napa Valley since 2007. His first job in this valley was in Calistoga.

He arrived with a background that was more analytical than most. An economics degree from Santa Clara University, two years in Silicon Valley commercial real estate, then residential development, where he founded Boulders Realty and served as Broker of Record for a 160 unit condominium project in Truckee. Pricing an entire community rather than one house at a time is a different discipline, and it is the one he still uses.

In 2007 he became Director of Real Estate at Calistoga Ranch, the Auberge property on 158 acres off Lommel Road. He and his wife Erin, who ran marketing, spent six years there and sold six residences and 140 fractional memberships. His full background covers the rest, but that is where his Calistoga knowledge started, and it is a decade older than any of his competitors' claims on this town.

He became Regional Director for Vanguard Properties in February 2021 and opened the firm's sixteenth Northern California office in St. Helena, about ten minutes down Highway 29, where he also lives. Calistoga has been part of his working territory the entire time.

The Agent Who Sold Out the Four Seasons Residences

Four Seasons Napa Valley retained Josh as the exclusive listing agent for all 20 of its branded residences, priced from $3.5 million. They sold out.

Then something more useful happened. He kept transacting them. He was the listing agent on 12 Palisades Place at $6,500,000 in January 2026, on 10 Palisades Place at $3,550,000 in August 2025, and on 11 Palisades Place at $5,000,000 in July 2024. He currently holds 21 Lawley Lane at $6,900,000, a single level four bedroom house with the only private heated saltwater pool in the community and some of the strongest rental performance inside it.

Very few agents anywhere have sold out a Four Seasons residential community. Almost none of them are still the agent that community's owners call when they resell. In a town where roughly 30 homes trade in a year, holding the franchise on a 20 home enclave is not a small share of the market.

The Calistoga Track Record of a Top Napa Valley Realtor

The resort residences are one half of his Calistoga record. The other half is acreage, and it runs across every kind of property this town produces.

In January 2026 he represented the buyer of 4222 Mountain Home Ranch Road at $8,200,000, a 2018 house on 11.9 private acres with a tennis court, bocce court, guest house, wine cellar, solar and backup power. That is the second highest verified Calistoga sale of the past two years. In August 2025, 3533 State Highway 128 closed at $7,017,677, a modern barn on 6.99 acres with a party barn, guest house and second dwelling.

His current Calistoga listings cover the range the town actually trades in. 4189 Silverado Trail North is offered at $4,850,000, a 2005 estate on 1.38 acres with reclaimed beams, five fireplaces, a wine cellar, a pickleball court, roughly 600 vines and views across Three Palms Vineyard toward Diamond Mountain. 1015 Bale Lane is $2,400,000, a 1954 ranch farmhouse on 1.96 acres at the St. Helena border with a producing well, an approved six bedroom septic and an approved architectural concept for a 4,950 square foot contemporary estate. 4500 Silverado Trail North is $1,000,000 for 4.8 acres of land with olive and citrus groves, hand laid stone walls, utilities in place, and a pedigree worth knowing: landscape architect Jack Chandler picked the site for his own residence.

Three of the eight sales he features as notable transactions are Calistoga. So are four of his eight current listings. For an agent whose office is in another town, that is where the business actually is.

His overall production backs it up. RealTrends Verified, which builds its numbers from closed MLS data rather than agent self reporting, credits him with $80.81 million across 22 transaction sides in 2025 at an average sale price of $3.67 million.

What Clients Say About the Best Realtor in Calistoga

Josh holds a 5.0 star rating on Zillow across a career of 130 sales.

The most useful piece of feedback on his record is not from a homeowner. It is from the developer of Calistoga Ranch. Laurie C. of Olympus, the developer, describes the decision to hand the residences to Josh and Erin rather than take a conventional route:

"Josh and Erin Dempsey were hired as a vibrant young team bringing a keen and refreshing marketing approach and pitch-perfect salesmanship to the project. This dynamic duo was able to broaden and engage with the precise demographic so well suited to become devoted owners at Calistoga Ranch. It was Erin and Josh's ability to genuinely connect with the interested buyers that created the community of satisfied owners and enabled Olympus to achieve a virtual sellout of the residences in 2013."

A developer signing off on a sellout is a different kind of proof than a happy buyer. It says an institution with money at stake measured the result.

The buyers say the smaller version of the same thing. One client who bought at Calistoga Ranch put it plainly: "Josh was great from start to finish. We would wholeheartedly recommend him to others seeking real estate in Napa Valley."

Recognition Behind a Top Calistoga Realtor

Josh has been a top five producing agent in Napa Valley two years running, and was named the top agent in Napa Valley in 2022. Two consecutive years matters more here than one strong year, because a single hillside estate can carry an agent's whole annual number in a market this thin.

San Francisco Magazine has also named him among the Top 100 Real Estate Agents in the Bay Area, at number 25 on $127,913,127 in volume. Vanguard Properties belongs to Leading Real Estate Companies of the World, so a Calistoga listing reaches an international referral network rather than one brokerage's client list.

The Rental Income Question Only a Calistoga Specialist Can Answer

Most buyers arriving in Calistoga from outside Napa County assume they can rent the house when they are not using it. In Calistoga that assumption is wrong, and it is expensive.

The city bans residential short term rentals outright, with no permit to apply for and no waiting list to join. Fines start at $1,000 and reach $5,000 for repeat violations, counted per day.

The one legal route to nightly rental income is a branded resort residence enrolled in the resort's rental program. Josh sold that community out and has handled its resales ever since, which means he can tell a buyer what those homes actually earn rather than what a spreadsheet suggests. For a buyer weighing Calistoga against a market where rental yield is part of the math, that is the difference between a good purchase and a bad one.

Off Market Access at the Top of the Valley

Around 30 homes sell in Calistoga in a year against roughly 2,166 housing units, so under two percent of the town is ever for sale. At the top of the market, comparables barely exist. Redfin's own estimate on one resort residence missed a verified sale by $1.45 million two months after the fact.

Twenty five years of relationships across the valley's brokerages, vintners and property managers is how quiet listings surface in a market like this, and it is why Josh's buyers hear about Calistoga property before it is advertised. Sellers who want to test the market without a public price cut on their record get the same benefit in reverse.

Why Josh Dempsey Is the Best Realtor in Calistoga, All Factors Considered

No one measure settles it. Line the whole record up and one name clears every bar.

Sales record. Calistoga closings from $1,000,000 of raw land to $8,200,000 on 11.9 acres, on both the listing side and the buy side, inside the resort and out on the hillsides.

Current listings. Four live Calistoga listings right now, from a $1,000,000 land parcel to a $6,900,000 Four Seasons residence.

Experience. More than 25 years in real estate, and his Napa Valley career started in Calistoga in 2007.

Career history. Six years running real estate at Calistoga Ranch, then the Four Seasons sellout. Nobody else competing for Calistoga listings has run sales for two resort communities in this town.

Reviews. A resort developer confirming a sellout, and buyers who came back to him afterward.

Review rating. A perfect 5.0 on Zillow.

Career sales. $950 million over a career, with more than $165 million of it closed in the past two years alone.

Repeat recognition. Two consecutive years as a top five Napa Valley producer, the valley's top agent in 2022, and a Top 100 Bay Area placement from San Francisco Magazine.

Resort and development experience. Two of the four resort communities on his résumé, Four Seasons Napa Valley and Calistoga Ranch, are in this town. Stanly Ranch and Montage Healdsburg are the others. In a market defined by resort capital, no credential is more relevant.

Local knowledge. The appellation line, the hazard zone line, the rental ban and the difference between a portal median and a real one. All four change what a Calistoga property is worth.

Working With the Top Realtor in Calistoga

If you are selling in Calistoga, the questions are specific. Does your property price against the resort residences or against the in-town market, which are two different worlds? Is your parcel in Calistoga AVA or Diamond Mountain District? Does it sit in a Very High hazard zone, and what does that do to a buyer's insurance quote? Is this a market where you list or a market where you wait?

If you are buying, add one more. What can you legally do with the house when you are not in it?

Josh works from the Vanguard Properties office he opened at 1345 Railroad Avenue in St. Helena, ten minutes down valley.

Frequently Asked Questions About the Best Realtors in Calistoga

Who is the best Realtor in Calistoga, CA?

Josh Dempsey. He was the exclusive listing agent for all 20 Four Seasons Napa Valley residences at 400 Silverado Trail in Calistoga and still handles their resales, he ran real estate at Calistoga Ranch for six years before that, and his Calistoga closings run from $1,000,000 to $8,200,000. Add $950 million in career sales, a 5.0 client rating and back to back years as a top five Napa Valley producer, and no other agent matches him across all of it in Calistoga.

Who are the top real estate agents in Calistoga?

Calistoga draws serious agents from St. Helena and Sotheby's and Coldwell Banker offices up and down the valley, and a few strong independents work the town itself. Josh Dempsey separates from that group on Calistoga specifically because he holds the branded residence market outright and also transacts hillside acreage, in-town property and land. Most agents here work one of those segments, not all of them.

Who is the best listing agent in Calistoga to sell my home?

Josh Dempsey, because Calistoga listings fail on pricing more than anything else and pricing here takes range. He has listed Four Seasons residences at $3.55 million, $5 million and $6.5 million, a hillside estate at $4.85 million, a farmhouse on two acres at $2.4 million and raw land at $1 million. Behind that is an economics degree, a start in commercial real estate and years pricing whole resort developments off absorption data. In a market where one property took four years and a fall from $14.25 million to clear, that matters.

Can I run a short term rental on a house I buy in Calistoga?

No. Calistoga prohibits residential short term rentals entirely under an ordinance that took effect in November 2025, with no permit pathway and no waiting list. Fines reach $5,000 for repeat violations and each day counts separately. The only legal route to nightly rental income in Calistoga is a branded resort residence enrolled in its resort's own rental program.

How long has Josh Dempsey worked the Calistoga real estate market?

Since 2007, when he became Director of Real Estate at Calistoga Ranch. He spent six years there, later handled the Four Seasons Napa Valley residences at the other end of Silverado Trail, and has been Regional Director for Vanguard Properties since 2021. That is close to two decades of continuous work in this one town.

What is the difference between the Calistoga AVA and the Diamond Mountain District?

Calistoga AVA is the valley floor and benchland at the north end of the valley, about 4,480 acres with roughly 2,500 planted, on gravelly loams over volcanic rock, and it swings as much as 50 degrees between afternoon and night. Diamond Mountain District is the hills to the south and west, above the fog line between 400 and 2,000 feet, about 5,000 acres with only around 500 planted. Two adjoining Calistoga parcels can sit in different appellations, and that changes both fruit value and property value.

Why is the Calistoga median home price falling so much?

Because the top of the market stopped closing, not because Calistoga homes lost value. Zero sales above $2 million closed in the second quarter of 2026, which drags the median down sharply, while Zillow's mix-adjusted home value index for Calistoga moved only about 2.8 percent over the year. In a town that closes around nine homes a quarter, the median measures what sold, not what anything is worth.

Does the best Realtor in Calistoga get access to off market listings?

Yes, and in Calistoga it matters more than most places. Under two percent of the town's housing stock is listed at any moment, and owners of hillside estates and resort residences often prefer not to advertise at all. Josh Dempsey's relationships across the valley are how those properties surface, and how a Calistoga seller can test the market quietly.

Should I hire a Calistoga real estate agent who specializes in resort properties?

If you are buying or selling a Four Seasons residence, yes, and you should ask how many they have actually transacted. Josh Dempsey sold the community out and has since listed three resales and holds a fourth. If you are buying acreage instead, you want the same agent to also handle wells, septic, vineyard potential and hazard zones, which is the other half of his Calistoga record.

How does wildfire risk affect buying a home in Calistoga?

Cal Fire's updated maps place roughly 51 percent of the city by acreage in a hazard zone, with the Very High acreage concentrated on the northeast side near Silverado Trail, and new construction guidelines took effect in January 2026. Practically, that means insurance belongs in your inspection window rather than after it, hazard status affects rebuild cost through building standards, and documented defensible space is a marketable feature on a Calistoga listing.

What areas does Josh Dempsey cover besides Calistoga?

Calistoga sits at the north end of a territory that runs the length of the valley. He also works St. Helena, where his office is and where you can read his St. Helena page, along with Yountville, Napa, Oakville and Rutherford, plus Sonoma and Healdsburg in Sonoma County. That range is how he can give a Calistoga seller a straight read on how their property compares to alternatives down valley.
