Let’s say you don’t need your dining room, so you’ve turned it into a home office. That might work well for you, but if you keep it looking like an office when you are trying to sell your house, you’re going to turn off a lot of buyers.
They won’t be able to visualize your house having a dining room, even though it’s right next to the kitchen and has a crystal chandelier hanging right over your copy machine.
You are much better off reverting your rooms back to their original purpose before trying to sell your house — or you just might confuse some potentially unimaginative buyers.
This goes for any room you’re using for an unexpected purpose. For example, if you’re using a bedroom as an office, consider adding a futon or daybed to the room, just to give buyers the signal that yes, this room really, truly is a bedroom.
This also goes for your garage. As tempting as it is to park all your boxes and extraneous items in this precious space, you’re better off moving them to a storage closet when your house is for sale, and using your garage for the luxurious purpose of parking your cars.
