For Sale by Owner is the twenty-fifth episode of Season 4, which was first broadcast on May 16, 1994.
The Banks family is offered a $1 million profit by an unknown wealthy client who wants to buy the family house. Clips are shown of previous memorable occasions. The only person who really doesn't want to move even for the money is Ashley, who shows the most sentimental attachment, a complete opposite to her brother Carlton who'd like to take the money and leave.
The clients are revealed to be Donald Trump and Marla Maples but it turns out that the Trumps were at the wrong address the entire time and leave with Carlton in pursuit. The family is happy that they didn't go through with selling the house.
