What tends to hold value

Industry cost-versus-value studies published each year by remodeling trade groups consistently show the same pattern: modest, visible upgrades recover the largest share of their cost. Garage doors, entry doors, siding, manufactured stone veneer and minor kitchen updates lead. Roof and window replacement recover a solid share because buyers expect them to be sound. Large upscale kitchen and bath remodels, additions and home offices recover the least.

How to think about it

A project that returns 60 percent of its cost is still a cost. The best reason to remodel is that you will use and enjoy the result. Resale value is a tiebreaker, and it argues for durable, neutral, mid-priced choices over top-of-the-line ones.

Fix the basics first

Buyers and inspectors flag roofs, water heaters, HVAC and electrical panels near the end of life. Replacing those protects the sale even if they add little visible appeal.

Common questions

What home improvement has the best return?

Exterior projects like garage doors, entry doors and siding usually top cost-versus-value rankings.

Does a new roof add value?

It rarely adds more than it costs, but an old roof can cost you the sale or a price reduction.

Does a kitchen remodel pay for itself?

Minor updates come closest. Upscale remodels recover the smallest share.
