To extend on Chish's post:

UK: Prime Minister traditionally (and officially) lives at 10 downing street

Canada: Prime minister official residence is 24 Sussex Drive

Venezuela: Though the current regime breaks the trend (probably because he's a crazed dictator who people want dead), the president traditionally lives at Miraflores palace

Australia: Prime minister lives at The Lodge (official name)

France: Élysée Palace

Ireland: Áras an Uachtaráin

Russia: Has several designated presidential residences, Putin lives at Novo-Ogarevo

It is EXTREMELY common in western society for leaders (elected or otherwise) to reside in a specific, pre-determined location; both for ease of access and security.

They don't just magically stop owning whatever residences they had prior to getting the job. When their replacement is elected, they simply move back into their old place.
