20 currently active listings have an observed price-change pair ending in this period. A listing can appear in both counts.
Calculated 2026-11-14 20:09 UTC. Source: this website's authorized MLS inventory. Import progress, freshness rules and coverage affect the figures.

Payment calculator
Explore a fixed-rate loan scenario. The price comes from this listing; a 20% down payment and 30-year term are starting assumptions, not requirements. Enter your own interest rate—not APR—and estimated costs.
Illustration only—not a rate quote, preapproval, lending offer or affordability determination. Assumes equal monthly payments on a fully amortizing fixed-rate loan; no adjustable rates, interest-only periods or balloon payments. Excludes closing costs, utilities, maintenance, special assessments and other unentered costs. Actual payments and escrow can differ. Review a Loan Estimate with your lender.
