The Complete List of Commercial Property Data Sources for Sales Teams

Every free and paid data source field service sales teams can use to research commercial properties — county records, satellite, permits, and more.

Free Data Sources

County Assessor/Tax Records: Building age, square footage, assessed value, ownership, and sale history. Available online for most US counties. The single best free data source for commercial prospecting.

Google Maps/Earth: Satellite and street-level imagery, nearby businesses, reviews, hours. The go-to for visual property assessment.

Building Permits: Recent permits indicate renovation, expansion, or new construction — all signals of service needs. Check your county's building department website.

FEMA Flood Maps: Properties in flood zones need specialized services. Free at msc.fema.gov.

USDA Web Soil Survey: For landscaping and irrigation companies, soil type data helps estimate project complexity.

Paid Data Sources

CoStar/LoopNet: The gold standard for commercial real estate data. Tenant info, lease rates, vacancy, and ownership. Expensive ($300-1,000+/mo) but comprehensive.

Reonomy: Property intelligence platform with ownership, transaction history, and debt data. Better for one-off lookups than bulk prospecting.

Apollo/ZoomInfo: Contact enrichment platforms. Find the facility manager, property manager, or building owner by company and job title. Essential for reaching decision-makers.

Nearmap/EagleView: High-resolution aerial imagery updated multiple times per year. Better resolution than Google Earth for roof analysis and property measurement.

Permit data aggregators (BuildZoom, ConstructConnect): Consolidated permit data across jurisdictions. Useful for identifying properties with recent construction activity.

Government & Public Records

Business Registrations: Secretary of State databases show which businesses operate at which addresses, who owns them, and when they were registered.

Environmental Records: EPA databases show facilities with environmental permits — useful for pest control, HVAC, and cleaning companies targeting regulated facilities.

Fire Department Inspections: Some cities publish fire inspection records, showing building type, occupancy, and compliance status.

Energy Benchmarking Data: Cities like NYC, Chicago, and Seattle publish building energy consumption data. Gold for HVAC and energy service companies.

How LotusLeads Combines Them

The challenge with all these sources is integration. Pulling data from 6-8 different platforms and manually combining it for each prospect takes hours.

LotusLeads aggregates property data, satellite analysis, contact enrichment, and competitive intelligence into a single profile for every commercial property in your territory. One search replaces hours of manual research across multiple databases.

The data is only valuable if it reaches your sales team in a format they can act on. That's the difference between raw data sources and a sales intelligence platform.
