Should We Remodel Our Current House or Buy Something Bigger?
By Curt Simmons, Broker · WA License 51380 · Keller Williams North Sound
As someone who spent ten years in construction before selling real estate, this is my favorite question, because there is a real answer, and it is not the one the renovation industry wants you to hear.
Start with the ceiling on your street
Before you price a single project, find out what the top of your neighborhood's market looks like. Every street has a ceiling: the most a comparable home has sold for, adjusted for condition. If your home is worth $700,000 and the strongest recent sale on the block is $780,000, a $120,000 addition does not get you to $880,000. It gets you closer to $780,000, if the addition is done well. You do not get to keep the first dollar you spend. You keep the spread between your home's current value and the neighborhood ceiling, minus the cost of getting there.
The two questions that decide it
- How much space do you actually need, and for how long? An addition or a finished basement solves a five-year problem. It rarely solves a fifteen-year one. If the kids are still home for a decade, the math changes.
- What does the move-up home cost versus the remodel? If the bigger house in your area runs $850,000 and your current home is worth $700,000, the gap is $150,000 before moving costs. If the addition runs $120,000 but only adds $60,000 of value, the remodel may still win on monthly cost, because you are not taking on a new mortgage at today's rate.
What remodeling does well
Remodeling keeps your rate, your neighborhood, your schools, and your commute. When rates were 3%, that math was overwhelmingly on the side of staying. At 2026 rates near 7.5%, the comparison is much closer, and the decision comes down to the numbers above: the ceiling on your street and the true cost of the move.
What moving up does well
Moving up buys the layout you want rather than the one you can bolt onto the house you have. Additions inherit the existing floor plan's weaknesses. A bigger house also resets the clock on the roof and the systems, and it puts your equity to work instead of into drywall.
My rule after two decades of this: if the remodel costs meaningfully less than the value it would add against your neighborhood's ceiling, remodeling can win. If the project costs as much as the gap between your home and the move-up home, the move usually wins, because you get the layout you actually want and you stop spending on a house you plan to leave.
Bring me your neighborhood, your floor plan, and the home you are eyeing, and I will show you the ceiling for your street and the true cost of the move. Then the decision stops being a feeling and becomes a line-item comparison.
