When Does Buying Beat Renting in 2026?

The rent-vs-buy decision in 2026 is harder than it's been in decades. Mortgage rates above 6%, plus high home prices and elevated insurance costs, mean monthly rent is often $1,500-2,500 cheaper than monthly ownership cost — even before maintenance and opportunity cost on the down payment. Buying still wins on long horizons, but the break-even has stretched from 4-5 years (2018) to 6-9 years (2026) in most California metros.

How This Calculator Works

This rent vs buy calculator 2026 | when does buying pay off? | tradecalcs uses real contractor pricing data from San Diego County projects completed in 2024-2026. The estimates include materials, labor, permits, and typical waste factors. Results are based on current market rates and adjust for project size, finish level, and location within San Diego County.

What This Calculator Includes

Why Local Pricing Matters

San Diego labor and material costs differ significantly from national averages. Coastal areas (La Jolla, Del Mar, Encinitas, Coronado) typically run 15-25% higher due to permit complexity, parking limitations, and premium material expectations. Inland areas (Escondido, Poway, San Marcos, Vista) are closer to baseline. Always get a specific quote for your project and location.
