Rancho Bernardo West attached homes had a strong October on paper: the median price jumped 54.7% year over year and sellers closed at 98.3% of asking, with homes moving in about 29 days. One caution — only 6 attached sales closed in the ZIP in October, so the median swings more than usual; the direction (firm prices, quick sales, 3.6 months of supply) still points to a market that favors sellers.

Zillow — Zestimate®: $413,100 (range $384,000 – $442,000). Well above the $248,000 paid in June 2016 — a decade of appreciation sits behind this figure.
The best-known consumer automated valuation model (AVM) in the U.S., built from public records, MLS data, and user-submitted facts on hundreds of millions of homes.
Published accuracy: median error about 1.77% for on-market homes and about 7% for off-market homes. The wider off-market error is the honest caveat — without a live listing, the model cannot see condition or upgrades.
MLS-driven AVM
Redfin — Redfin Estimate: $415,162. Within about $2K of the Zillow figure — the two consumer and MLS-driven models agree closely here; up about $3K since October.
Redfin is both a brokerage and a portal, so its estimate draws directly on MLS data and hundreds of data points — Redfin cites 500+ — including listing details other portals may not receive as quickly.
Published accuracy: median error about 1.85% on-market and about 7.25% off-market — very close to Zillow, with a different data emphasis.
Aggregator · Not a standalone model
Homes.com — average of 4 AVMs: $450,311 (range $418,243 – $485,000; values based on Sep 2026). Highest of the three verified headlines — its First American component ($485,000) is the top single AVM on this page.
Homes.com does not run its own valuation model — it aggregates four lender-grade AVMs and averages them: Collateral Analytics $435,000 · ICE Mortgage Technology $463,000 · First American $485,000 · Quantarium $418,243.
Collateral Analytics is now part of ICE via Black Knight; ICE Mortgage Technology powers a large share of U.S. mortgage origination; First American is a title-data giant whose records cover 99% of U.S. deeds, mortgages, and foreclosures; Quantarium is an AI-driven model trained on parcel and imagery data.
Our method
United Home Price Estimate: $426,191.
It is the equal-weight average of the headline estimates verified on this page:
($413,100 + $415,162 + $450,311) ÷ 3 = $426,191
No single algorithm sees a home the way an appraiser walking through it would. Averaging independent models — consumer, MLS-driven, and aggregated — smooths out any one model’s blind spots and outliers.
Heat score · 78 / 100 · Strong seller's
How the 78 is built — each SDAR 10K Research input is scored 0–100 by band, then weighted:
Months Supply of Inventory — 3.6 mo Score 80 · × 40% = 32
Sales to List Price Ratio — 98.3% Score 60 · × 25% = 15
Days on market — 29 days Score 80 · × 20% = 16
Median price YoY — +54.7% Score 100 · × 15% = 15
Heat = 0.40 × Supply + 0.25 × Sales to List Price Ratio + 0.20 × DOM + 0.15 × Median YoY
Why strong seller’s? Three of the four inputs score high: prices are up sharply year over year, inventory sits at 3.6 months, and homes sell in about 29 days. The one softer input is the sales-to-list ratio at 98.3% — strong, but not over-asking — which keeps the score at 78 rather than the top of the scale.
Industry anchor (NAR): under 4 months of supply is a seller’s market, 4–6 balanced, over 6 a buyer’s market — which is why supply carries the largest weight.
