Accurate property owner contact info

[Bridgette Delva]

What data source provides the most accurate phone numbers and addresses for property owners? 

We have a paid BeenVerified subscription and I'm a Realtor so I have access to Forewarn - I have found that BeenVerified's information is grossly outdated and inaccurate when compared to Forewarn.

I can't use Forewarn for skip tracing since it goes against the intended use as a Realtor - is there any data source out there as accurate as Forewarn, that I could subscribe to? 

I'm looking for something that can be used for one-off searches to find investments for our portfolio so we aren't doing batch skip-tracing or wholesaling.  I'm not a wholesaler but I do a lot of research to find buildable lots in our target area (I'm also a GC).

If you’re looking for accuracy closer to Forewarn without using Realtor-restricted tools, most investors and developers rely on real estate–focused data platforms rather than consumer people-search services. Platforms like PropStream, PropertyRadar, and Reonomy are commonly used because they’re built around deed, tax, and ownership records, which generally makes owner names, mailing addresses, and phone numbers more reliable for property research. For buildable lots and targeted investor searches, many GCs and portfolio investors also layer in parcel and land data tools such as LandVision or property intelligence from providers like Data Axle to cross-check ownership and contact details. While no data source is perfect, platforms designed specifically for property intelligence tend to be far more accurate and practical for one-off investment research than general background-check subscriptions.
