When Gabe Claypool was looking for a house, he called on realtor Casey Oakes for assistance. She helped him find and buy a charming two-story cottage in a great neighborhood. In the process, they also found out that they were a great match and decided to get married. When their house was on the market, buyers all noted it's biggest flaw-three nice bedrooms upstairs, but no bathroom. There's a fourth smaller room upstairs without a closet. The obvious idea is to put a bathroom in that space, but most buyers didn't want to tackle adding new plumbing to a 1918 house. Now, with a budget of $20,000, Gabe and Casey are going to take the challenge head on. It's going to take some major plumbing work to get the room ready for a bathroom, but the Claypools think that they can do the rest themselves and not only add equity, but make it much more attractive to any future buyer.
