When Maggie, 27, and Matt McGaugh, 31, bought a house in Caddo Lake, Texas, they had no idea they'd end up with two homes and an estimated $25,000 in "valuable collectibles and stunning pieces of furniture" that the previous owners of one of the properties had left behind.

The McGaughs first bought a three bedroom, two bathroom house for $350,000 in April, with plans to convert it into an Airbnb. They then learned the property next door was on the market.
