When Barack Obama moved into the White House, he brought with him lots of experts, strategists, and friends. Some were insiders who had lived here for years; others were transplants who had to scramble to find a place to live.

Here’s a look at the homes of President Obama’s brain trust.

Observatory Circle

Cost (2000): $2.9 million.

Assessed value: $4.9 million.

The President’s former rival sleeps and entertains in this brick Georgian just off DC’s Embassy Row. A stone’s throw from the Vice President’s residence, the six-bedroom house is on a secluded street that’s also home to businessman and Republican fundraiser Wayne Berman and architect Leo Daly. Clinton and husband Bill also own a five-bedroom Dutch Colonial in Chappaqua, New York, which they bought in 1999 for $1.7 million.

Dupont Circle

Cost (2009): $395,000.

Assessed value: Not available; individual units aren’t assessed in cooperative buildings.

The President’s 28-year-old wordsmith bought a one-bedroom, one-bath unit in the Chastleton, an eight-story Gothic-style building at 16th and R streets, Northwest. Homeownership is a big change for the heartthrob, who shared a house in Chicago’s Lincoln Park neighborhood with six Obama campaign staffers before moving to Washington.
