I bought a 1,200 square foot home a few years ago and since the market is hot I’m thinking of selling. When I bought the house the hot water heater and washing machine were in the fairly small kitchen. I moved them up into the attic to create a nice kitchen. I had my construction guys sort of finish out the attic by putting in electric plugs and silverized foam board for walls and ceilings. Although the floors were 70 years old I put down a coat of polyurethane by myself and think it looks pretty good. I built a wall dividing the attic space in half so that I could store my stuff behind a locked door it I rented the place out on Airbnb and wanted to let my guests use the laundry equipment.
So I am using 350 square feet of my attic space as a utility room on a regular basis and 350 square feet just to store stuff. Without question the second-floor space makes the house a whole lot more livable. But what do I need to do to properly claim some or all of this area as square footage? My thinking is to put sheetrock over the foam board. Anything else. Obviously being able to honestly market my house as having 1,550 or 1,900 square feet is going to draw more interest than a 1,200 square foot listing would.
