CORRECT ANSWER:
They made the right decision and saved money long term.
They basically broke even financially long term.
Those 90 days cost them thousands more over the long term.

They kicked off on a high note with a $5,000 discount on the home's price. But that's where the good news stopped. As interest rates rose, their monthly payment increased too. Over 20 years, this seemingly small $110 bump in their monthly payment would actually cost them over $20,000 more, even after accounting for the initial discount. So, as you can see, what looks like a small saving can end up being quite costly!
