About Mara Flash

Mara Flash Blum, Associate Broker, Senior Global Real Estate Advisor, has consistently ranked among Sotheby’s International Realty top producers, since rankings began in 2009, as well as The Wall Street Journal/Real Trends annual report. Her challenging work, deep knowledge of the real estate market and tenacious spirit propels her to close deals under any market condition. Expanding her services to her client base, in 2020 she joined forces with her longtime partner, Nikki Field and founded The Flash Collection, the downtown division of The Field Team. Their uptown/downtown partnership has provided their clients with the benefit of two top ranking real estate mavericks. The Field Team is the #1 Ranked Team of Global Portfolio Advisors with Sotheby’s International Realty, servicing referrals from around the world through global partners. Another accomplishment includes the successful sellout of downtown's most distinguished new development prewar condominium, 212 Fifth Avenue with its $80 million penthouse sale. Mara consistently performs for her sellers, positioning their homes in the marketplace to sell at the highest possible sales price. Staging, pricing, negotiating, and closing are her strengths. Recognized as a downtown leading expert, Mara regularly advises developers seeking real-time market intelligence regarding supply/demand and pricing conditions. With a record of sales achievements across a broad array of Manhattan's premier neighborhoods, Mara earns enthusiastic referrals from her loyal client base that buy and sell with her repeatedly. Whether downsizing or upgrading, her joy comes from servicing her clients well and transitioning them to their new homes and new beginnings.
