When you live in an older home, it's very much like stepping into a time capsule. Our home was built in 1984, and it hadn't been updated much since then when we bought it. From carpet under the oven to a washer/dryer combo in the guest bathroom, it was a wild adjustment.
Your first impulse is to modernize. Usually, this refers to cosmetic upgrades like new flooring, cabinetry and a fresh coat of paint. Oh, and removing the washer/dryer combo from the bath.
