"These guys can sell water in the rain"

Laurie Kramer

Seller of 3329 Prospect Street NW Unit 4

"Daniel and his team have been advising my family on our real estate portfolio for years. I cannot imagine working with anyone else. I’ve referred him to all of my fellow MD’s and all of them feel the same way."

Dr. Liz Kim

"I met Danny when he sold me my first condo in 2014. Since then, he’s represented me on 5 more transactions. Danny earned the trust of my parents, sister and my multiple business partners and has evolved into one of my best friends."

Dr. Ehsan Abdeshian

"I’ve been developing homes in Washington for years and have never come across anyone like the HEIDER Team. They’ve sold all of my recent projects in record time at either the very highest price per square foot or the highest sales price on record which is why they’re now my dedicated in-house sales team."

Mike Ardekani

Principal at Ziba Management

"My wife and I are repeat HEIDER clients, and consistently refer their good name to everyone we know looking to make a move. We have felt his unwavering commitment to excellence and our bottom line since the first day we met. We’re on our second purchase with Daniel and both times we beat out competing offers. He’s always out maneuvering the rest of the market."

The Franklin Family

"Danny has become a member of our family after artfully negotiating an excellent deal on behalf of me and my husband on our very first home. He recently sold my mother’s home after her broker couldn’t get the job done. He and his team are designed to win."

The Rahimi Family

"In 2019 alone, they sold my project in Great Falls in 3 days where the average amount of days on market was previously 780 days that house, Chateau de Lune sold for $9.2MM. They sold another one of my projects in Bethesda at 0 days on market for $7MM (roughly a million dollars higher than market value) - both transactions were the highest sales in each respective market in years. They’re winners through and through and I’m proud to have them as my exclusive in-house real estate advisors."

Mike Mafi

Principal of The Building Group LLC

"The best compliment I could give would be that after working with Danny as a client I was inspired to leave my job in medical sales to join his team and blaze a new path as part of HEIDER. When you witness something special you are willing to take risks."

Nicole Terry

Senior Sales Advisor at HEIDER

"The HEIDER Team led by Daniel and Justin approaches the sale of your home with creativity, zeal, and an incredible amount of attention to detail - which has always been critical but is now absolutely necessary as the market evolves into a more challenging one."
