I am in th industry of getting homes ready for market and I also buy older homes and renovate them for resale... Go tiles through.. here is the reason, very clean, closet are the worst for dust because things sit in there collecting it. Tile floor you'll sweep through with your vacuum and mop much easier... Go carpet and you have to stop and change the setting or the head of the vacuum for that small area, pain in the butt.... You'll love the look of tile it will make both areas look bigger.
