Let me take you on a little tour. I live in a condo with my husband, for the last 11+ years. When faced with the choice between buying something that suited us better or staying here a little while longer, we choose to hang on here and make some changes we could enjoy for the next few years that would also improve resalability.
Primary thing that has been bothersome the entire 11 years is a countertop dividing the kitchen from the dining room. One of the two drawers wouldn't open due to the refrigerator, and one of the cabinets was super deep and that made it super hard to get things out of it! Plus, a large stain on the carpet has always had to be covered because the previous owner couldn't get it out (and an additional stain from spilling coffee since!)
