The HEIDER Company | TTR Sotheby's International Realty

Customer Experience

The HEIDER Company occupies a renovated two-story grey brick townhouse at 2531 P Street, recognizable by a red lacquered door, a small H monogram above the lintel, and a clean awning reading simply “HEIDER” over a flower-boxed window. It looks like a discreet residential address until you notice the branding — which is intentional. This is a real estate team that operates on the luxury end of the market and signals it through every detail, from the office aesthetic to the concierge-level service model.

The practice is led by Daniel Heider, Executive Vice President at TTR Sotheby’s International Realty — and, per the firm, the youngest EVP in TTR Sotheby’s history. He built the team from a solo practice he started around 2016 after coming up through Washington Fine Properties and TTR Sotheby’s. The operation now numbers roughly sixteen people across sales, operations, and marketing, and its clients — buyers, sellers, and the occasional renter — get a service model that extends well past a standard transaction: curated staging, drone photography, private listing access through the team’s own HEIDER Private platform, and the kind of attention to detail that has made Heider something of a media fixture in Washington luxury real estate.

Claim to Fame

The numbers are hard to argue with. In 2025, The HEIDER Company closed $621 million in sales and pending volume, with $208 million of that through private listings. The team claims 100% market share for all DC residential transactions at or above $20 million for three consecutive years — a run that includes the $28 million sale of Halcyon House in Georgetown to Commanders owner Josh Harris, a reported $25 million sale of the Howard Lutnick estate on Foxhall Road (described at the time as the most expensive DC home sale ever), and the $23 million Mark Zuckerberg property on 30th Street.

Those figures have translated into consistent rankings: #1 team by sales volume at TTR Sotheby’s for six straight years, #1 small team in the Capital Region in the Wall Street Journal’s RealTrends rankings (three years running), and Washington Business Journal Broker of the Year in 2023. Fortune named the team the second-highest performing Sotheby’s team worldwide in early 2026. The Georgetowner, Washingtonian, Axios, and The Wall Street Journal have all covered the team at length.

Preparing for Your Visit

The office doesn’t post walk-in hours — this is a by-appointment practice, and the right way to engage is through the contact form at heidercompany.com or a call to (202) 938-3685. Whether you’re buying, selling, or exploring an off-market listing, the first step is a conversation.

The main TTR Sotheby’s International Realty Georgetown brokerage is at 1206 30th St NW; the HEIDER Company’s dedicated office at 2531 P St is a few blocks east on the same street. Street parking on this stretch of P is limited, but the location is walkable from much of Northwest DC.
