Condo Replacement Cost Estimator

Estimate condo replacement cost for HO-6 dwelling coverage using square footage and local rebuild cost per sq ft.

Replacement cost is what it would take to rebuild your unit interior at current construction prices, not your purchase price or market value.

Insurers use rebuild estimates to set dwelling limits on HO-6 policies. Enter local figures from your agent or quote to plan coverage.

Common questions

Is replacement cost the same as purchase price?: No. Replacement cost estimates rebuilding the unit interior at current construction prices. Market value includes land, location, and demand factors your HO-6 dwelling limit should not mirror blindly.
Who provides rebuild cost per square foot?: Your insurance agent, a contractor familiar with local condo finishes, or the insurer's replacement cost estimator. Enter that figure here; we do not look up local indexes.
