Mortgage
From Tardis Wiki, the free Doctor Who reference
Having lost the TARDIS on Krop Tor, Rose Tyler teased that the Tenth Doctor would have to get a mortgage to afford a house, now they were stranded. The Doctor was terrified at the prospect. She said that she would have to get a mortgage, too, and suggested she'd like them to live together, and "share". (TV: The Impossible Planet)
In a parallel universe, a family in Leeds got kicked out of number 29 for missing a single mortgage payment. Donna Noble later moved in to their old home, with Wilf and Sylvia, after being relocated from London. (TV: Turn Left)
