As we close 2025, we reflect on our transformative year of innovation in luxury real estate transactions. With $5 billion in historic sales and commanding 85 percent market share in the luxury auction segment, we continue to redefine how the world’s most exceptional properties change hands.
Our new Private Auction platform represents a groundbreaking approach that delivers the competitive dynamics, pricing, and time certainty of an auction (typically 60 days to close) with complete discretion. This approach provides sellers with direct access to our Private Client Group—over 16,000 luxury buyers including 250+ billionaires, founders, and family offices—while maintaining absolute privacy. Buyers gain exclusive access to premier, never-listed properties unavailable through traditional channels, and our curated platform ensures exceptional properties only, while the competitive format guarantees transparent pricing and efficient transactions.
Abu Dhabi Collectors’ Week presents an unprecedented convergence of luxury real estate and collectible markets, with live bidding commencing 5 December. For the first time, the world’s finest real estate will auction alongside collector cars, high jewelry, and rare timepieces as Sotheby’s Concierge Auctions joins Sotheby’s and RM Sotheby’s. Featured offerings include Saint-Jean-Cap-Ferrat in French Riviera, France—an extraordinary first-line waterfront estate with 680 square meters of refined living space and spectacular Mediterranean sea views—and Graz, Austria, a four-story contemporary sanctuary featuring ARCUS, an architectural masterpiece by Zaha Hadid within a UNESCO World Heritage city.
Our End-of-Year Sale brings exceptional opportunities across two days in New York City on 17-18 December. Featured properties span diverse markets and property types: Miami, Florida offers a once-in-a-generation development opportunity at a premier Biscayne Boulevard address—a fully entitled 82-story mixed-use tower with luxury residences, hotel, retail, and commercial spaces, currently operating as a hotel with transformative potential. Okeechobee, Near Palm Beach, Florida presents Oasis Ranch, a distinguished Martin County ranches estate embodying sovereign independence with timeless elegance across 20 private acres along Scenic Highway. International offerings include Uvita, Costa Rica, an extraordinary tropical sanctuary where 10 acres of pristine rainforest meet unparalleled luxury just minutes from world-renowned beaches, featuring complete privacy with river and waterfall access. Navasota, College Station Area, Texas delivers a legacy opportunity at Bavista Ranch, a spectacular 642-acre estate with rolling terrain, ponds, and sweeping vistas defining the Texas landscape. Silverleaf, Scottsdale, Arizona showcases an architectural masterpiece in the exclusive Upper Canyon of Silverleaf, representing the pinnacle of desert luxury living.
Consignment opportunities remain available for upcoming sales in Phoenix/Scottsdale during Arizona Car Week, New York City during Sotheby’s ‘Visions of America’, Miami during RM Sotheby’s ModaMiami, Hawaii, and beyond.

For sellers
For luxury property, the buyer pool is limited. This makes selling luxury real estate a challenge that the traditional market alone has not yet solved.
Concierge Auctions eliminates the uncertainty of selling a luxury property by pairing sellers with eligible buyers in an auction process designed for closing in 60 days or less.
For agents
Concierge Auctions is an additional tool for agents to sell unique, high-end listings. Our approach combines the benefits of traditional brokerage with the structured timeline of an auction.
We’re not agents, so agents working with us always keep their listings and receive a full commission. Closings are contingency-free.

Your guide to the world’s finest property platform
From Aspen to the Amalfi Coast, our global platform connects the right buyer to the right home - fast. Here’s how we do it.
Selling with us
Your fast pass to global exposure and a 60-day close.
WHY SELL AT AUCTION?
The world’s finest art, classic cars, yachts, and antiques are sold at auction—so, too, is luxury real estate. Timing is everything and luxury real estate can move slowly. According to our Luxury Homes Index, homes that take over 180 days to sell close at an average of 19% less than their listing price. Our auction model accelerates the process, with global exposure, competitive bidding, and a 60-day start-to-finish timeline. We are an added tool rather than an alternative to selling traditionally, and in all instances, we partner with a listing broker on each sale.
WHY DO I NEED A LISTING AGENT?
We are an auction house and not a brokerage firm. On average, a third of our buyer demand is generated by the local market. Managing local listings requires agents who can operate in specific areas. Over two decades, we have found that local buyers prefer to work directly with the listing agent or a local brokerage community. Having an agent, therefore, increases the chance of successful sale. Buyers appreciate the ability to speak with a local agent to get a professional opinion on the property.
HOW DOES THE PROCESS WORK?
We bring you the market and the competition drives the price. Prior to the auction opening, we promote your property both globally and locally for three weeks with world-class sales, digital, and public relations campaigns. The auction will open for two weeks once a Market Reserve has been set. The sale of your home will be followed by an as-is, contingency-free closing, typically within 1–4 weeks after the auction closes.
Buying through us
The smart way to shop for the world’s most exceptional homes.
WHAT IS THE BIDDING PROCESS LIKE?
Our auctions are fast, fair, and fully transparent. You’ll see all terms up-front and compete only with pre-qualified buyers online, over the phone, or in person at a live sale. It’s the easiest way to name your price on a world-class property. You are empowered to submit a starting bid, and in doing so, unlock up to a 50% rebate on the Buyer’s Premium if you are the winning bidder.
DO I HAVE TO INCLUDE A BID AMOUNT WHEN I REGISTER?
It is not required to submit a bid amount when you register; however, if you are interested in taking advantage of our Starting Bid Incentive to receive a rebate on the Buyer’s Premium, you must submit a Starting Bid prior 5pm, local property time, the day prior to bidding opening. Our platform combines security, speed, and transparency, giving buyers a more streamlined way to compete for the world’s finest properties.
ARE THESE PROPERTIES DISTRESSED?
Not at all. We sell unique properties for clients across a variety of circumstances. The one thing they all have in common is that they chose the auction process after careful consideration and with an eye toward unlocking market value. We only accept the finest properties on our platform and decline 95% of the applications. We have the most extensive database of high-end real estate buyers in the world.
Representing through us
Give your clients the control to sell or buy their luxury property on a set timeline.
HOW DO WE WORK WITH AGENTS?
Born out of the luxury real estate industry, Concierge Auctions is an additional listing and buyer agent tool. We have never auctioned a property without partnering with a listing agent and endeavor to include agents in every step of the process. Commissions are paid according to your listing agreement.
WHAT DOES OUR TEAM HANDLE FOR YOU?
Your auction team will arrange showings, manage leads, network with brokers and potential buyers, and work throughout your property’s exposure period to engage the market. We will screen for suitable buyers and reach out to potential bidder segments from our database around the world. Each buyer is assigned a Bidder Representative, and buyers agents are looped into communications to stay informed every step of the way.
