Plot.
The Simpsons throw a Mardi Gras party, having invited most of the town, and Homer reluctantly invites Ned Flanders at Marge's insistence. As they clean up the house the following morning, Lenny asks how they pay for the huge yearly party. Homer gleefully confesses that he borrows from a home equity line to do so, calling his home a "sucker" for getting stuck with the bill. Marge and Homer visit their mortgage broker, Gil Gunderson, after receiving a letter and find out that their adjustable rate mortgage payment has increased drastically because of Homer's ineptitude. The Simpson home goes up for auction and after seeing the Simpsons' sorrow, Ned outbids Mr. Burns, purchasing the home for $101,000 and then offers to let the Simpsons move back in and rent the property from him. The Simpsons thank Ned with a song and a small celebration, when Marge notices the sink faucet dripping. Ned offers to fix it, as he is now their landlord and the repairs are his responsibility, along with some other items that he is obligated to correct. However, Ned quickly tires of their constant requests for repairs.
Despite Ned's best efforts, Homer gets mad at him and denounces him to the media as a corrupt slumlord. When Homer refuses to apologize for his ingratitude, Ned tells them they must leave at the end of the month. The Simpsons move Grampa into the house with them in order to take advantage of a loophole in the eviction laws, but Grampa decides to live in Ned's house instead due to the better living conditions, automatically evicting the Simpsons, who are forced to sleep at a homeless shelter. While interviewing some potential tenants, Ned sees a picture from the move-in celebration and remembers the Simpsons' happiness and admiration of him. Ned lets the Simpsons move back into their house, ignoring the new tenants' threat of legal action. The rest of the Simpsons' neighbors promptly move away, disgusted at this decision.

The episode received generally positive reviews from television critics. 
Robert Canning of IGN said it can sometimes be difficult for an animated television show to "stay current, what with their lengthy production schedules that start months before the episode actually airs", but with "No Loan Again, Naturally" he felt like "if they wrote and animated everything just a few weeks ago. Well, the initial concept, anyway. With the Simpson family losing their house, it was up to Ned to come in and save the day. But what he couldn't do was keep this episode from feeling very middle-of-the-road." 
Erich Asperschlager of TV Verdict thought the episode delivered on "its deceptively simple premise in spades. Any time you get this much Ned Flanders, good things are bound to happen. Mix in a good deed well-punished and you’ve got a real winner."
Steve Heisler of "The A.V. Club" gave the episode a B+ writing, "This episode's story was actually fairly original, which surprisingly doesn't happen all that often. Yeah, the story was mighty predictable, but what I liked about tonight's "Simpsons" was that it ventured into character-based territory, rather than an oddball, plot-driven direction."
