Former Nationals manager Dave Martinez is selling his Arlington home. With a sleek and modern black-and-white exterior, the home at 637 21st St. S. is currently for sale for $2,500,000.
Martinez was fired from the baseball team on July 7, along with general manager Mike Rizzo. According to Zillow price history data, he bought the home in February 2024 for just over $2.2 million.
Built in 2024, the home includes five bedrooms and four and a half bathrooms, with a total interior area of 4,754 square feet and a lot of 0.14 acres. It’s located in the Addison Heights neighborhood.

In the entrance, you’re immediately greeted with 9-foot ceilings, wide-plank hardwood floors, refined architectural details, and curated finishes throughout the house. There is a staircase at the entrance leading upstairs and a long hallway navigating through the office, formal living room, living room and kitchen.

In the living room, dark wood beams on the ceiling add visual interest to the space. It’s steps away from the kitchen and breakfast nook, and it has double doors leading to a screened-in porch.

The kitchen has Wolf/Sub-Zero appliances, quartz countertops, and a waterfall island. The all-wood cabinets and white backslash give the kitchen a modern farmhouse feel. In addition to the large kitchen, the home also includes a butler’s pantry for more food storage.

The primary suite grabs your attention with its wide wood paneling and natural light. The tray ceiling adds dimension to the room, making it look taller. It has an expansive walk-in closet with ample storage space.

The en-suite bathroom takes your breath away with the marble flooring, walk-in shower, and his-and-her sinks.

Outside, you’ll find a screened-in porch with a staircase that leads to the back yard. The porch includes ceiling-mounted heaters and is a prime spot to relax while enjoying the weather.

The back yard is fully fenced to provide privacy. The all-gray patio is perfect for summer barbeques and relaxing on an Adirondack chair.
