Getting Phone Numbers for Owners

[Erica Rome]

Hi,

My husband and I have started a wholesale real estate business and have been successful finding homes that are great opportunities but our biggest struggle is getting accurate phone numbers to contact the owners of the home to try to get them to sell the house and get it under contract. 

What websites or method's have you used that you have found successful? 

We've tried Spokeo.com but it has proved to have very unreliable data and continually asks for more money. 

We are looking for the highest value tool or resourse. Any and all advice welcome!
