The 35th president was born and raised in Brookline, of course, but when he returned from World War II to run for Congress, he rented Apartment 26 at the old Bellevue Hotel at 21 Beacon Street.

New York City’s mayor was born in Brighton, and grew up in a 3-BR, two-story Colonial in Medford that his mother lived in until she died in 2011 at age 102. Since her death, Bloomberg has visited Medford less and less.

Boston’s mayor-for-life and wife Angela live in a two-story house in Hyde Park’s Readville section, near where Menino was born and raised. Every year, the couple hosts a block party for their Chesterfield Road neighbors. Retail politics, people.

The president leased a basement apartment in Somerville while a student at Harvard Law in the late 1980s. He found the apartment through a newspaper ad (remember doing that?). According to his landlord, who is apparently happy to talk about his old tenant, Obama always paid the rent on time.

The Republican presidential nominee and wife Anne own a 2-BR, 3.5-BA townhouse in Belmont Hill. They bought it for $895,000 in June 2010, after the year before selling the 6,434-square-foot, 6-BR, 6.5-BA Belmont estate that served as the de facto Governor’s Mansion in the middle of the last decade. The Romneys moved to Belmont in 1971, according to The Globe, after buying a house on Winn Street.

The governor and wife Diane have been trying to sell their Milton home of 20 years since 2009, but with no success (they have an estate in the Berkshires, too). They have listed the five-bedroom, 3.5-bathroom, 6,880-square-foot spread for as much as $1.9 million; but it disappeared from the market in December 2010, when listed for $1,725,000. The couple bought the house in April 1989 for $560,000.

The Democratic Senate nominee and husband Bruce Mann bought the three-story, 3,728-square-foot Victorian in September 1995 for $447,000. It’s now assessed by the city at $1,740,700.

The greatest president of the 20th century lived in the 600-square-foot, four-room Adams House suite (with a chum from Groton) from 1900 to 1904, while a Harvard undergrad. It had all the latest accoutrements, including a bathroom, central heat and electricity (bully!). There’s an effort under way to preserve the suite as a museum.

The frontrunner for Massachusetts’ Fourth District moved to this apartment building last winter, fresh off his engagement and his announcement to run for Barney Frank’s congressional seat.
