ZIP 91765 Housing Market & Real Estate Update — February 22, 2026

ZIP 91765 (Diamond Bar, CA) continues to look like a higher-price, slower-moving (but still active) market as we head toward the spring listing season. Today’s quick read is built from the latest ZIP-level dashboards across major portals.

Top takeaways

Inventory is active: Realtor.com shows 113 homes for sale, with a median listing price around $1.18M.
Recent closed-sale pricing is steady: Redfin’s January 2026 snapshot shows a median sale price near $958K (about +0.3% year over year).

Market snapshot (latest available)

Pricing: Realtor.com’s 91765 dashboard pegs the median list price at about $1.18M (about $549 per square foot). Redfin’s ZIP trends (based on MLS/public records) put January’s median sale price at roughly $958K. That gap is a reminder to separate list prices from what’s actually closing.

Supply: With roughly 100+ active listings showing on major portals, buyers generally have more options than in a truly tight market. For sellers, presentation and realistic pricing matter more when shoppers can compare several similar homes in the same school area.

Sales and ‘what’s actually closing’

Looking at recent sold activity feeds for Diamond Bar, sale prices in the ZIP can span a wide range depending on lot size, views, and renovation level. If you’re pricing a listing (or making an offer), pull comps that match your home’s condition and layout, not just the neighborhood name.

Rentals check

On the rental side, Realtor.com lists a median rent around $3.3K for 91765. If you’re deciding between selling and holding as a rental, this is the moment to run a fresh cash-flow check (insurance, taxes, HOA, and maintenance) rather than relying on last year’s numbers.

What’s for sale nearby (no addresses)

Single-family homes in the ‘move-in ready’ bracket tend to cluster near the ZIP’s median list price, while larger upgraded homes often push well above it.
Condos and townhomes can be a relative value play, especially if you screen carefully for HOA level and recent special assessments.
Watch for price-improvement alerts: in a ~70+ day DOM environment, reductions can create the best entry points.
