Zillow — Zestimate®: $1,684,000 (range $1.58M – $1.80M). The lowest of the three verified headlines by a wide margin — about $158K under the Redfin 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: $1,842,441. Up about $27K 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.
CoreLogic / Cotality AVM
Realtor.com® — RealEstimate℠: $2,099,000
Realtor.com surfaces several professional AVMs under one page. Its core engine traces to CoreLogic — now Cotality — the property-data firm whose models lenders, insurers, and appraisers have used for decades.
Aggregator · Not a standalone model
Homes.com — average of 4 AVMs: $1,994,351 (range $1,916,404 – $2,099,000; values based on Oct 2026). The highest headline; its four components cluster between about $1.92M and $2.10M.
Homes.com does not run its own valuation model — it aggregates four lender-grade AVMs and averages them: Collateral Analytics $2,099,000 · ICE Mortgage Technology $2,026,000 · First American $1,936,000 · Quantarium $1,916,404.
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: $1,904,948.
It is the equal-weight average of the headline estimates verified on this page:
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 · 68 / 100 · Seller's
How the 68 is built — each SDAR 10K Research input is scored 0–100 by band, then weighted:
Months Supply of Inventory — 2.3 mo Score 80 · × 40% = 32
Sales to List Price Ratio — 97.1% Score 60 · × 25% = 15
Days on market — 40 days Score 60 · × 20% = 12
Median price YoY — +4.9% Score 60 · × 15% = 9
Heat = 0.40 × Supply + 0.25 × Sales to List Price Ratio + 0.20 × DOM + 0.15 × Median YoY
Why seller’s? Inventory is the anchor: only 2.3 months of supply, with sellers closing at 97.1% of asking and the median up 4.9% year over year. Days on market (40) scores mid-band — homes are not flying off the shelf — which keeps the score at 68 rather than higher.
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.
