Outdoor spaces add value. A well maintained deck or patio can create a nice gathering space and make a backyard more appealing. The cost of a deck or patio can vary greatly depending on size and ‘bells and whistles.’ Obviously, keep in mind the more added, the longer is it to recoup. So stay away from the elaborate outdoor kitchen with wood fire pizza oven and granite bar. Always stay on the more modest side, maintain things well, keep clean and organized and this will have maximum appeal to perspective buyers.
