MLS values are reported for this listing, not prior sales. Observation dates show when our importer saw an asking price, not when the MLS changed it. Up to 24 observations are retained; changes between refreshes may be missed. This is not a complete price or sales history.
Property taxes
Tax history is not available from the imported listing data.
Source: MLS feed. Only supplied tax years are shown, up to 10 years; this is not a county tax archive. Amounts may be corrected and taxes may change after purchase. Verify assessments and current taxes with the county. These values do not automatically fill the payment calculator.
Market trends in Walnut
Active residential homes for sale in Walnut, CA, available through this website's authorized feed. Includes residential subtypes; excludes rentals. Not the entire market or a valuation of this property.
Observed price activity · past 30 days
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 20:30 UTC. Source: this website's authorized MLS inventory. Import progress, freshness rules and coverage affect the figures. Medians exclude missing/invalid values; price per sq ft is the median of individual listing ratios. Price observations are limited to the last 24 per listing and may miss changes between refreshes. This is not a complete 30-day market report, historical inventory trend, appreciation measure, or sold-price analysis.
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.
