We bought a campground in 2016 for $1.6 million—today it's worth $6 million

Mark Lemoine, 53, took a leap of faith in 2016 when he resigned from his state government job to pursue his lifelong dream of owning a campground. He and his wife, Karla, also 53, acquired the Coloma/St. Joseph KOA Campground in southwest Michigan for $1.6 million. After numerous renovations, new additions and dedicated care, their campground's value has skyrocketed to $6 million. Correction: This story has been updated to correct that the campground was 42 years old at the time when it was purchased by the Lemoines.
