Eberhart Brothers is a family-run real estate company that owns and manages residential properties in Manhattan. The firm was founded in 1927 by Frank and Walter Eberhart, sons of Frank Eberhart Sr., who served as president of the House and Real Estate Owners' Association of the Twelfth and Nineteenth wards in the early 1900s. The company operates from its office at 312 East 82nd Street, where it has been located for over 50 years. Eberhart Brothers owns and manages more than 1,000 apartments across Manhattan, primarily in low-rise walk-up buildings featuring turn-of-the-century architectural details and high ceilings. The company's portfolio is concentrated on the Upper East Side, with properties clustered between First and Second Avenues. The firm operates with an in-house architectural and construction management staff that handles building design, renovations, and maintenance. Eberhart Brothers offers rental units ranging from studios to four-bedroom apartments and two- to three-story penthouses, with many units featuring garden patios or rooftop terraces. David F. Eberhart currently serves as President. In 2015, the company's portfolio generated over $28 million in total revenue.
