The Home Improvement Payback Guide
What pays you back when you sell, and what does not
Thinking about a project before you sell, or wondering whether the remodel you want will hold its value? This page collects all 21 guides in one place. Each covers a single project in plain words: what the job includes, what it cost, what came back at resale, and the California rules that change the answer here.
The honest headline first. In the 2025 Cost vs. Value Report for the San Francisco metro, five of the twenty projects this guide covers were credited at resale with more than they cost, and four of those five are on the outside of the house. The report changed how it measures between editions, so read every figure here as a ranking with a year stamp, never a promise for any one house. The smart question is rarely which room. It is which tier: the simple version or the showpiece.
New here? Start with the big picture.
One post walks the whole table: the $30,000 cliff, why outside beats inside, and how the length of time you plan to stay changes the math.
Read the ranked overviewStart at the curb, where the paybacks run highest
The projects a buyer can see from the street held their value best in the study.
Siding, windows, and roofs protect the sale as much as the house
Big ticket exterior work, where insurability and fire rules shape the local answer.
Kitchens sell homes, and the small one keeps the most money
Three tiers of the same room. The smallest project returned the biggest share.
Bathrooms are for the years you live there
Every bathroom remodel in the study returned well under what it cost.
Decks add living space outside, at a price
Wood against composite, and what buyers actually paid back for each.
New square footage costs the most and returns the least
Both returned under half their cost, and the primary suite ranks last of all twenty. Here is when they still make sense.
Cents per dollar is the share of the job cost credited back at resale, from the 2025 Cost vs. Value Report for the San Francisco metro, which takes in Fremont, Newark and Union City. Each figure is an average across that whole metro, so it ranks the projects rather than prices your house.

Before you remodel, know your starting number.
The remodel conversation belongs 6 to 12 months before you list, while every option is still open. Start with what your home is worth today, then decide what, if anything, is worth doing.
