David Siddons found a reason to write about Miami real estate in a report that irritated him. In 2011, he was reading an assessment of the local market prepared by analysts in Washington, D.C. They could see the numbers. He wondered how much they could see of Miami. A city examined from a distance can look remarkably tidy. Buying a home in it is usually a less orderly experience.
He began producing his own reports in 2012. That small act of professional disagreement became a recurring habit: look more closely, explain the difference, publish the explanation. Today, it connects the neighborhood research, videos, analytics and conversations that surround the David Siddons Group at Douglas Elliman. Before those became parts of a business, there was the question of whether the prevailing explanation was good enough.
The report that bothered him
Siddons had entered real estate in 2008, a year that offered an unusually stern introduction to property optimism. Originally from the United Kingdom, he made his career in South Florida and his home in the Miami area. His public biography places him in Ponce-Davis with his wife and two daughters. The geography of his working life includes Coral Gables, Coconut Grove, Pinecrest, Brickell and Miami Beach.
His answer to that distant report was to bring the observer closer to the subject. He wanted to explain the forces underneath a transaction, including distinctions that an average could smooth away. His own description of the ambition was straightforward: I wanted to write a personal narrative about the market
. The interesting word is personal. He was proposing that experience on the ground belonged alongside the calculations.
A city in the plural
By December 2013, Siddons was working with EWM International, with an office in Brickell and sales production exceeding $20 million. His market reports were already part of his professional identity. Asked about Miami's growth, he discussed its increasing importance as a business center for Latin America, the arrival of companies and employees, and buyers coming from abroad. He saw a place becoming more than a holiday address.
Then he made a distinction that would remain useful throughout his career. Condos and single-family houses had different supply dynamics. More units could arrive in the condo market; the supply of houses in a particular neighborhood was less flexible. A slowdown in sales could therefore require some interpretation. Fewer transactions might reflect fewer available homes. The same headline could conceal different conditions.
“You can’t find what isn’t available.”
David Siddons, 2013
That observation lacks the glamour of a rooftop pool, which is perhaps its virtue. It asks a buyer to think about what is actually available in the relevant market. A useful adviser must be able to move between the broad story of Miami and the stubborn particulars of a building, a street or a household's requirements.
The business behind the byline
Writing on his own eventually required a different organization. By 2015, Siddons says, the business had an operations director and was beginning to assign territory managers to neighborhoods. The structure gave local expertise a place in the daily operation. Someone had to know what was happening within each smaller market and bring that knowledge back into the conversation.
In July 2019, his group moved from EWM Realty to Douglas Elliman. The announcement recorded more than $81 million in team sales for 2018. Siddons explained the decision in terms of Elliman's luxury brand and its national and international reach. Buyers were coming from across the country and overseas; he wanted the organization around his team to support that business.
The same announcement described another application of his research: consulting for Terra's David Martin on digital marketing and market analytics for Park Grove and Eighty Seven Park. His team also represented buyers in those projects, including a $15 million purchase at Eighty Seven Park. The analytical work had become something a developer could commission as well as something a buyer could read.
2025 sales volume recorded by RealTrends for the David Siddons Group, classified as a large team.
A later snapshot shows the scale of the operation: RealTrends records $363.28 million in team sales volume for 2025. Numbers like that measure business completed. They do not settle the harder question of why people choose an adviser. To understand Siddons's proposition, it helps to look at the work offered before a client arrives at a closing.
A spreadsheet meets a sales pitch
The published origin of Condo Geeks begins with another buyer's dissatisfaction. Salil Gupta bought a Miami condo and later felt that a glossy brochure had played too large a part in his decision. For a subsequent purchase, he downloaded years of closed sales and examined the history of buildings and neighborhoods. The exercise was useful, and laborious.
Siddons was assembling reports from spreadsheets. Gupta was interested in making historical information easier to use. Their shared concern was accessibility: how could someone making a substantial purchase inspect the relevant data without first undertaking a private research project? Condo Geeks brought comparisons of buildings and neighborhoods into a tool that could show prices per square foot, sales, discounts and days on market over time.
The practical appeal is easy to understand. A buyer can put an attractive listing beside the history of its building and compare it with alternatives. Desire still gets a vote. It simply has to share the table with evidence. In a business where presentation is part of the product, that is a worthwhile seating arrangement.

An audience with questions
Research also needs readers. Siddons's website, LuxLifeMiamiBlog, won South Florida Agent magazine's Best Agent Website award in 2021. Its combination of property searches and market explanation made publishing a visible part of the practice. The award recognized a piece of the business that customers could examine for themselves, before an appointment or a viewing.
The brokerage work continues alongside the publishing. In July 2026, Siddons represented the seller of a newly built Ponce-Davis mansion that sold for $18.9 million. Its most recent asking price had been $22 million. There is a useful reminder in the gap: an asking price begins a conversation whose outcome still has to be negotiated. Even an expensive house must eventually meet an actual buyer.
He has also explored the other side of real estate's visual appeal. In a conversation with agent and video creator Jason Matouk, Siddons considered how broad video exposure and detailed market knowledge could work together. A property can require both a substantial audience and an explanation of its particular value. Analysis does not relieve a seller of the need to get people interested.
His own public manner allows some room for puncturing the performance. In a TREM Group interview updated in April 2026, he discussed the strange practice of filming podcast-style clips without an actual interviewer. Talking into a camera can manufacture the appearance of a conversation. He also declined an interviewer's attempt to place him among the famous guests of a Miami studio. Professional visibility apparently has its limits, even in Miami.
That conversation also returned to a more practical concern: whether an agent has a meaningful digital presence when a seller entrusts them with a listing. The distinction is between appearing busy and demonstrating work that reaches people. Siddons is a participant in the attention business, with a direct commercial interest in the answer. His interviews are more revealing when that interest stays in view.
More people in the room
The Better Decisions podcast extends his practice of explanation into discussion. A January 2025 episode with Eli Beracha, professor of real estate and finance at Florida International University, examined population growth, supply, migration and market risks. Its chapter list moves from large economic forces to questions for sellers and investors. The format lets a neighborhood adviser bring another kind of expertise into the room.
In November 2025, Siddons took a different microphone as emcee of FIU's REact conference. The program brought together real estate and finance practitioners, with speakers including Miki Naftali, Craig Robins and Stephen Bittel. The conference theme, “Navigating the Unknown,” suited a career built around explanation. It also acknowledged the condition under which every property forecast must operate.
There is a more modest side to his ambition in his own reflections on the work. He has pointed readers toward his earliest real estate video as an example of an imperfect attempt worth making. He writes about learning from mistakes, remaining calm in negotiations and continuing to learn by explaining things. These are his stated working principles, offered by someone whose business depends on clients accepting his judgment.
The resulting portrait contains an adviser, a publisher and a salesman, all occupied with the same city. Each role has something to ask of the others. The publisher needs a reason to keep returning to the subject. The salesman needs people to pay attention. The adviser needs the explanation to remain useful after the excitement of a viewing has passed.
Siddons's career began with a demanding market and acquired direction through a report he thought could be better. The habit that followed is still recognizable. Miami supplies the properties, the pictures and the promise. He keeps making room for the follow-up question.
