REMODELING COST VS. VALUE FOR SELLERS
Eight of the top 10 projects with the highest cost vs. value ratio are exterior replacement projects. These generally perform better because they are among the least expensive projects to complete and are non discretionary improvements that contribute to curb appeal, a strong subjective factor among home buyers. The projects that recouped the most at resale are: Entry door replacement, garage door replacement, siding, wood deck addition, minor kitchen remodel, window replacement, attic bedroom remodel, and basement remodel. Home office remodels and sun room additions recouped the least. Source –CRS Magazine 2011
