Will Upgrading Your Home Help You Sell It?
Big-Ticket Renovations Lose Value Amid Market Slump; Investing in Curb Appeal

If you’re putting your home on the market anytime soon, you may want to rethink those plans to bump out the kitchen or add an extra bath.

During the housing boom, such ambitious projects would recoup as much as 90 cents on the dollar. Not today. The resale value of improvements in general is sliding, according to experts. In a departure from recent trends, homeowners are getting the best payback from relatively mundane improvements, such as sprucing up the exterior of their house or putting in new windows.

After spending $400,000 remodeling the suburban East Greenwich, R.I., home he bought for $820,000 in 2002, Jonathan Salinger learned he probably couldn’t sell it for more than $1.1 million in today’s market. That’s after posh additions that included landscaping, a pool, an outdoor kitchen, first-floor laundry and mud rooms, and custom cabinetry. As a result, the 45-year-old district manager for a mortgage lender recently decided not to list his house for sale and scratched plans to move the family closer to his children’s private school in Providence.

The slumping housing market has made remodeling much trickier. When house prices were climbing ever higher, buyers knew they could spend big bucks to expand their homes and still make a profit when it came time to sell. But today, a buyer who spends unwisely on remodeling may be simply digging a deeper hole when it comes time to move.

Further complicating the equation: Even though housing prices are slumping, construction prices have continued to climb. That means adding that new bath will cost more, even as it contributes less to the resale value.

Nationally, returns for all major home-improvement projects are fetching 70 cents on the dollar, according to a Remodeling magazine survey of real-estate professionals conducted late last year. That’s down from 80 cents in 2004. Back then, a minor kitchen remodel cost an average $15,300 and recovered an estimated 93% if the home was resold within a year. Today, a similar remodel costs $21,100 and would recoup only about 83%.

Some elaborate remodels, though, may actually make your home harder to sell, says New Mexico builder Lonny Rutherford. He notes that lenders are nixing higher-than-normal appraisals, and that many buyers are looking for a deal. Even if someone wanted to pay extra, they “would have a hard time financing the house unless they have a lot of cash,” he says.

Inferior remodeling work may be worse than none at all. Cheap cabinets and poor workmanship won’t fool buyers as they might have a few years ago, when many had to make snap decisions about buying a house, says Anslie Stokes, a real-estate agent in Washington, D.C.

“Buyers can spot shoddy renovations, and they aren’t willing to pay for it anymore,” Ms. Stokes says.
