- In 2021, O'Mara and Adam Dunnigan bought a 120-year-old chapel, saving it from demolition.
- The church, topped with a 65-foot steeple, was basically a rotting "birdhouse" when they bought it.
- The couple spent a year turning it into a $250-a-night Airbnb and have just put it up for sale.
O'Mara and Adam Dunnigan were golfing in Detroit Lakes, Minnesota, in the summer of 2021 when they noticed a tiny white chapel perched on a two-acre plot between rolling green hills.
"We were like, 'Oh, look at that cute little church," O'Mara, a 39-year-old real-estate agent, told Business Insider.
