Nine of the top 10 most cost-effective remodeling projects involve exterior replacement work, according to the annual Cost vs. Value survey.

 According to the report, replacement projects usually outperform remodel and addition projects in resale value because they are among the least expensive and contribute to curb appeal. Various types of siding and window replacement projects were expected to return more than 70 percent of costs. Upscale fiber-cement siding replacement was judged by REALTORS® the most cost effective among siding projects, recouping 80 percent of costs. Among the window replacement projects covered, upscale vinyl window replacements were expected to recoup the most, 72.6 percent upon resale. Another exterior project, a wood deck addition, tied with a minor kitchen remodel for the fourth most profitable project recouping an estimated 72.8 percent of costs.

The top interior projects for resale value included an attic bedroom and a basement remodel. Both add living space without extending the footprint of the house. An attic bedroom addition costs more than $51,000 and recoups an estimated 72.2 percent nationally upon resale; a basement remodel costs more than $64,000 and recoups an estimated 70 percent. Improvement projects that are expected to return the least are a midrange home office remodel, recouping an estimated 45.8 percent; a backup power generator, recouping 48.5 percent; and a sunroom addition, recouping 48.6 percent of costs.
