Every year, RealTrends Verified publishes independently audited production data on real estate professionals across the country, and it's one of the only rankings in the industry built entirely on closed transactions rather than self-reported claims or paid placements. We're glad to share that The Zach Zeldner Team at Compass has been named a top-ranked team in the 2026 RealTrends Verified rankings, based on 2025 sales data.
Our 2026 RealTrends Verified Rankings
RealTrends ranks teams using two core metrics: sides (the number of transactions closed) and volume (the total dollar amount of real estate sold). Here's where our team landed this year:
- #1 Medium Team in Colorado by Sales Volume
- #1 Medium Team in Boulder by Sales Volume
- #2 Medium Team in Boulder by Transaction Sides
- #15 Medium Team in Colorado by Transaction Sides
These rankings are based on 93 closed transaction sides and $190.14 million in sales volume in 2025, with an average home price of $2.04 million.
What "Sides" and "Volume" Actually Mean
- Sides counts each transaction a team represents, whether as the buyer's agent or the listing agent. A strong sides ranking points to consistent, current experience across many transactions.
- Volume is the total dollar value of everything a team sold. A strong volume ranking shows a team is trusted to handle high-value homes and complex transactions.
Ranking #1 in Colorado by volume, while also placing in the top two locally by sides, reflects a team that is both highly active and consistently trusted with substantial transactions.
Why This Matters When You're Choosing a Boulder Realtor
Boulder County has no shortage of agents, and it's genuinely difficult to tell from marketing alone who actually closes at a high level. RealTrends rankings are useful precisely because they're built on independently verified, closed transaction data rather than reviews or advertising spend. A team ranking at the top of the state, in a market as competitive as Boulder, is an outside confirmation of results, not a claim we're making about ourselves.
A Track Record Built Over Time
This year's ranking sits on top of a longer history of production in Boulder and Boulder County. The Zach Zeldner Team has closed more than $1.7 billion in sales since 2019, and is independently ranked the #1 real estate team in Boulder and Boulder County by sales volume based on IRES MLS data via BrokerMetrics for 2025.
Boulder Neighborhoods and Boulder County Areas We Know Well
This ranking reflects work across every part of Boulder, not just a handful of streets. Our production spans the full range of Boulder's neighborhoods, from Newlands and Mapleton Hill to Chautauqua and beyond, along with the surrounding Boulder County communities of Niwot, Louisville, Lafayette, Longmont, and Gunbarrel.
Whether you're buying a single-family home on the east side of Boulder or selling one near the foothills, you're working with a team whose results are verified at the state level, backed by neighborhood-specific knowledge across the entire city and county.
