Where to Find List of Landlords

[Sarah Fulton]

Hi guys (and gals)! I started a property management company recently and am looking for a website or resource where I can locate people that own multiple properties. My goal is to get a list to mail-to, although if there’s a way to get phone numbers, that would be better. 

I have access to the MLS and County Assessor page. The title company in our area says they cannot provide any lists for any criteria. I live in a rural town in Oklahoma, if that helps.

Any suggestions greatly appreciated!
