The fine folks at Bankrate.com have clocked in with another look at the ROI of home remodeling. Here’s a bit of a summary:

According to the survey, remodeling a bathroom costs an average of $51,374, with 63.6 percent of that being recouped at resale. A major kitchen overhaul costs an average of $109,935 and delivers the same percentage in resale value as a bathroom.
Steel entrance doors, however, cost about $1,162 and deliver 96.6 percent of that when you sell your home. A wood deck addition costs an average of $9,539 and recovers 87.4 percent of that on resale. For siding (fiber-cement) the cost is $13,378, with 87 percent recouped. A garage door costing $2,791 will deliver 82.9 percent.
