Property Valuation with AI: How ATTOM Data Gives Your Agent Real Estate Intelligence

ATTOM property data — AVMs, sales history, tax assessments, rental estimates — is now accessible to AI agents through Pipeworx Housing Intel. Metered per query.

ATTOM Data Solutions is one of the largest property data providers in the United States. Their data powers real estate platforms, lending decisions, insurance underwriting, and investment analysis. If you’ve used a tool that gives you a home value estimate, there’s a good chance ATTOM data is behind it.

Accessing ATTOM directly has traditionally required an enterprise contract — annual subscriptions that start in the thousands of dollars. Through Pipeworx Housing Intel, your AI agent can access ATTOM data on a per-query basis. No enterprise contract, no annual commitment. Metered access to institutional-grade property intelligence.

What ATTOM provides

Property detail (attom_property_detail)

Complete property characteristics for any address: bedrooms, bathrooms, square footage, lot size, year built, stories, property type, and more. This is the foundation for any property analysis.

Automated Valuation Model (attom_avm)

ATTOM’s AVM provides an estimated market value for a property based on comparable sales, property characteristics, and local market conditions. This is the same class of valuation model that lenders and institutional investors use for preliminary assessments.

Sales history (attom_sales_history)

Every recorded sale transaction for a property — sale dates, sale prices, buyer/seller information, and transaction types. See what a property sold for in 2015, 2019, and 2023 to understand appreciation patterns.

Tax assessment (attom_assessment)

County tax assessments including assessed value, land value, improvement value, and tax amounts. Assessed value vs. market value gaps can indicate opportunity or risk.

Rental AVM (attom_rental_avm)

Estimated rental value for a property based on local rental market data. Essential for investment analysis — combine with the purchase AVM and you can estimate cap rates and cash flow potential.

Nearby schools with ratings, distance, grade levels, and enrollment. School quality is one of the strongest predictors of property value in residential real estate.

Find properties by address, ZIP code, or geographic area. The starting point for market research and portfolio analysis.

Market-level sales volume and price trends by geography. See whether a market’s transaction volume is increasing or declining and how median prices are moving.
