No, I would not suggest a master bedroom with a bath in the basement. For your best return, kitchens and baths are the items that bring you back the most return. If these areas need attention, I would put some money into these areas. For the basement a finished family room and some much needed room for storage would be ideal. Contact Team Gardiner and we can give you some ideals. We have a certified Staging Expert as well as contractors on our team that we can recommend as well. Call me for your free pre-listing visit.
