4. Railroad Houseboat

Designed By: Unknown 
What It’s Worth: $300,000-$400,000*
Where It’s Docked: Sausalito, California 

One of the more unique houseboats on this list is the Railroad Houseboat, and it was even featured on the HGTV show Extreme Homes. The Railroad Houseboat is part of a huge group of houseboats in Sausalito, California. It was created using an 1800s Pullman railroad car.

The car was converted into a houseboat, but the original features and accoutrements of the car were kept as intact as possible. This means that the Railroad Houseboat truly does look like a floating railroad car. The houseboat is 2,000 square feet, and it stands out among the other 500 houseboats docked in Sausalito.
