A couple hasn't paid for flights since 2018 and lives in homes for free. Here's how they quit their corporate jobs for house-sitting gigs all over the world.

• Marco Ilagan, 42, and Fran Cassaniti, 30, left their jobs at Accenture to travel in 2018. 
• The couple live in other people's homes for free in return for looking after their pets. 
• They have saved $50,000 each year in accommodation.

Travel enthusiasts Fran Cassaniti from Buenos Aires, Argentina and Marco Ilagan from Chicago, Illinois were in a long-distance relationship. And while most people in long-distance relationships hop on FaceTime calls, Cassaniti and Ilagan had date nights in all parts of the world. They met in India, Thailand, or Brazil to spend time with each other.
