We're budgeting $400,000 to flip 5 train cars into Airbnbs. It all started with a 1970s caboose we bought on Facebook marketplace.

• Real-estate investors Ray and Karen DeVite weren't sure what to do with land they bought in Xenia, Ohio.
• One night, Karen spotted a historic 1970s caboose on Facebook Marketplace and got inspired. 
• Now, the couple is budgeting at least $400,000 to build an Airbnb park for train enthusiasts.

One Ohio couple is all-in on ambitious project to turn historic train cabooses into short-term rental getaways.

Ray and Karen DeVite spoke to Business Insider about the project, which all began with a fateful Facebook Marketplace scroll. The couple had purchased land in Xenia, Ohio with the intention of developing it. One night, Karen was scrolling Facebook and by chance saw an advertisement for a historic train caboose.
