Maybe it was the mountain-bike heist.

Former first daughter Jenna Bush and her husband, Henry Hager, have moved out of their South Baltimore rowhouse and put it up for sale. The couple bought the two-story, 1880s rowhouse for $440,000 in March 2008 and moved in shortly after their wedding that May.

The 3BR, 3BA end-of-group property, listed this week for $474,900, boasts a private garage, “luxurious sea grass carpeting” and unspecified “security features.” (Not that the security system did much to deter the thieves who swiped two Trek mountain bikes from the couple’s garage in June.)

It’s not clear if Bush and Hager continue to live in Baltimore or the area. Will Runnebaum, a broker with Marcus-Boyd Realty, which is listing the house, was not authorized to say.

Shortly after moving to the area, Bush taught at SEED School of Maryland, a public boarding school in Baltimore. She left this fall, according to Laura O'Connor of the SEED Foundation. 

In August 2009, she also started work as a part-time correspondent for the “Today Show” out of NBC’s Washington bureau. Has her work for NBC prompted a move? A network spokeswoman did not respond to messages seeking comment.

Hager continues to work for Constellation Energy, Constellation spokesman Larry McDonnell confirmed this week. But McDonnell declined to say if Hager is still employed in Baltimore or if he’s working somewhere else for the energy conglomerate.

David Sherzer, a spokesman in former President George W. Bush’s Dallas office, wasn’t talking either.

“Unfortunately, we don’t comment on the girls,” said Sherzer, who grew up in Maryland and volunteered this much: “I’m the only Orioles fan in the [Dallas-Fort Worth] metroplex.”

Wherever she went, Jenna Bush demonstrated some political savvy in the way she moved out. She knew enough not to hire Mayflower, the company some Baltimoreans still blame for relocating the Colts to Indianapolis. A neighbor who spied the movers last week tells me it was an unmarked truck.
