Nine of the top ten most cost-effective projects in terms of value recouped are exterior replacement projects, according to the National Association of Realtors 2010–11 Remodeling Cost vs. Value Report.

Among the report’s findings:

  • The steel entry door replacement is the project that returned the most money, with an estimated 102.1 percent of cost recouped when the home is sold.
  • The midrange garage door replacement is expected to recoup 83.9 percent of costs.
  • Upscale fiber-cement siding replacement was deemed the most cost-effective among siding projects, recouping 80 percent of costs.
  • Upscale vinyl window replacements were expected to recoup the most among window replacement projects, at 72.6 percent.
  • Wood decks tied with a minor kitchen remodel for the fourth most profitable project, recouping an estimated 72.8 percent of costs.

Meanwhile, here’s what the study found inside the house:

  • An attic bedroom addition costs more than $51,000 and recoups an estimated 72.2 percent.
  • 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.

In addition, the study found that Texas was among the regions that were consistently estimated to return a higher percentage of remodeling costs when a home is sold.
