What data sources do you use?

We aggregate data from multiple sources including MLS listings, county tax records, permit data, and proprietary market analytics to provide the most comprehensive valuation possible.

How often is data updated?

Our market data is updated daily, and our AI models are retrained weekly to ensure you always have access to the most current valuations.

Our Methodology

Transparency is one of our core principles. Here's exactly how we calculate your home's value.

Data Sources

MLS Listings

Active and historical listing data including list prices, days on market, and price changes.

Public Records

County tax assessments, deed transfers, and property characteristics from assessor databases.

Permit Data

Building permits reveal renovations, additions, and improvements that affect value.

Market Analytics

Real-time market conditions, inventory levels, and price trends at the neighborhood level.

School Ratings

School district boundaries and ratings from GreatSchools, which significantly impact home values.

Neighborhood Data

Demographics, crime statistics, walkability scores, and amenity proximity.

The AI Model

Our valuation model is a gradient-boosted ensemble trained on over 50 million residential sales transactions from the past 10 years. The model learns complex relationships between property features, location factors, and sale prices.

Key model characteristics:

Trained on 50M+ transactions across all 50 states
500+ features including property, location, and market variables
Retrained weekly to capture current market conditions
Separate sub-models for different property types and price tiers

We also use a large language model to generate plain-English explanations of the valuation factors, making the results accessible to non-experts.
