What are the best data sources for company owner contact info?

Hi everyone,

I'm on the hunt for a robust data source that can provide a nationwide list of property management companies—complete with owner contact details. I’ve hit a wall with the usual directories and online databases and thought this community might have some hidden gems or insider tips.

If you've come across any software/services with high quality data at a reasonable price, I would love to hear about it..

Additionally, if you have tips on verifying the accuracy of such data or know of any alternative approaches to compile this information, please share! Your insights could save a lot of time and steer me in the right direction.

Thanks in advance for your help and suggestions—I really appreciate the collective knowledge here!

Cheers,

Jason
