After too many years of financing Homer's annual Mardi Gras party on home equity loans, Homer and Marge's adjustable-rate mortgage skyrockets and they are forced to put their house up for sale. Flanders does a good deed by outbidding Mr. Burns and purchasing the property, thus becoming Homer and Marge's new landlord. But when Homer publicly accuses Flanders of neglecting the Simpsons' unsafe living conditions, Flanders threatens to throw the family out on the streets. Blackboard: 'I will not have fun with educational toys'.
