Mary Lou Mercer

Mary Lou Mercer has been a top-producing Realtor for more than 25 years. Geographically, she specializes in the Park Cities, Preston Hollow, and North Dallas. Financially, her specialty is turning homes into investments.

“No matter the price, I’m always thinking resale,” she says. “It’s all about your money.”

Her clients must appreciate that attitude, because they keep coming back. Ninety percent of her business is from repeat customers or referrals.

Ranked among Dallas’ best Realtors by both D Magazine and the Dallas Business Journal, Mary Lou has also received her company’s two highest distinctions for her consistent annual production and for her total accumulated sales volume.

Mary Lou has a history of service to the Dallas community, donating her time and talents to organizations such as the Salvation Army, Meals on Wheels, the Junior League of Dallas, the Church of the Incarnation, the Park Cities Historic and Preservation Society, and Preservation Dallas.

Her career can be summed up by three key adjectives:

 • Honored: In addition to her media accolades, Mary Lou’s colleagues have selected her to receive the Award of Excellence for professionalism in service to her clients.

Connected: Mary Lou is a member of the Network Council, which allows her to associate with other Realtors who specialize in the upper end of the Dallas residential market.

Educated: Mary Lou is a Graduate of the Realtor Institute (GRI) and a Certified Residential Specialist (CRS). Each designation requires 90 hours of classroom instruction.
