Built For Your Industry

Property owner data powers workflows across mortgage, insurance, real estate, and more

Mortgage Marketing

Build targeted outreach lists for refinance and home equity campaigns. Identify high-equity homeowners and reach them with relevant offers. For marketing outreach only — not for underwriting or credit decisions.

Home Services

Target homeowners by property characteristics — roof type, year built, pool, lot size — for roofing, solar, HVAC, and landscaping outreach campaigns.

Direct Mail and Marketing

Build targeted mailing lists with verified owner addresses. The mailing address field captures where absentee owners actually receive mail, not just the property address.

Real Estate Platforms

Embed owner lookup directly in your PropTech product. Give your users property intelligence and owner contacts without building the data layer yourself.

Real Estate Investment

Find motivated sellers, absentee owners, and distressed properties. Look up ownership details and contact info for acquisition outreach campaigns.

Frequently Asked Questions

Common questions about the Property Owner Lookup API

No charge. You only pay for hits -- if the API cannot find owner data for the address you submit, zero credits are deducted. The response will indicate a miss so your application can handle it accordingly.

Phone numbers are skip traced on demand with DNC, TCPA, and carrier flags included on every number. Each lookup triggers a new query — not pulled from a generic pre-built file. For additional compliance, you can run phone lists through our DNC Scrubbing service.

The API is primarily designed for residential properties. Commercial property data is limited and may not include full owner contact information. For best results, use it with single-family homes, condos, townhouses, and small multi-family properties.

Rate limits are documented per endpoint in the API documentation. Limits are designed to be generous for production use cases while preventing abuse. If you need higher throughput for enterprise-scale integrations, contact support and we can adjust your limits.

This page focuses on owner contact data -- looking up who owns a property and how to reach them. The full Lead Builder API adds 90+ property filters, AI-powered natural language search, and batch list building for finding properties you don't already have addresses for. Both use the same endpoints and credit balance.
