For the first time in more than 65 years, The Rose Heard House, a 117-year-old manse next to George Washington University, is for sale. The brick Federal-style house is currently the headquarters of Action on Smoking and Health, an antismoking non-profit. But when the company's lease runs out next year, a new owner will move in. We'll let you know who buys it—and if it goes for the asking price of almost $5 million.  

Democratic lobbyist Julie Domenick, a veteran of the Investment Company Institute and The Loeffler Group who recently announced she is opening a lobbying shop called Multiple Strategies, moved across town to be closer to clients.

Domenick collected $1.6 million for a four-bedroom Burleith row house on Ivy Terrace Court and moved to a three-bedroom, four-bathroom Victorian row house on Capitol Hill. The new house, which she got for its list price of $1.15 million, has more than 3,200 square feet and a master bedroom with sitting room and atrium.

On the 300 block of C St., NE, the house is steps from the Hart Senate Office Building—a convenient perk.

Every Thursday we're going to offer a round-up of some appealing open houses for the coming weekend. We scoured real estate web sites and classifieds to produce this weekend's list—a mix of prices and styles in the District, Maryland, and Virginia. A caveat: We haven't visited any of these houses ourselves, so we're working off the same information you'd read in the ads. 

If you stop by any of them, let us know how it went—leave a comment over the weekend or send an email. Was the house better than you expected? Worse? We'll keep your comments in mind for next week's list. And if you are a real estate agent or homeowner hosting an open house next weekend and think you have something special, please let us know about it: mfleury AT washingtonian DOT com. 

A new cell phone version of Monopoly says the White House is worth $3.2 million.

Glu Mobile, a California-based company that creates mobile entertainment for cell phones, is about to launch Monopoly Here & Now, a cell phone version of the famous board game. A company press release says the program "brings a classic game into the modern era with new properties, a set of animated tokens, and current real estate prices." 

In this new, high-tech version of Monopoly, the White House has its own square with the "current real estate price" of $3.2 million. Considering three-bedroom townhouses in Georgetown can go for more than $3 million, the figure seems low. 

According to DC tax records, which split the property into three parcels, the assessed value of the White House and grounds is about $935,000,000.

Nosy neighbors were thrilled last February when Zillow.com launched. Founded by Rich Barton and Lloyd Frink, the duo that created Expedia.com, Zillow.com uses square footage and recent comparable sales prices to provide free home-value estimates.

Zillow's success has led to copycat ventures, all of which have enormous voyeuristic appeal. Whereas real estate used to be a private matter, it's now possible to anonymously peak at the house values of neighbors, bosses, relatives, friends, and ex-boyfriends (not that I would EVER do such a thing).
