Driving for dollars, collected addresses, what to do next ?

[Raheem Mentor]

Hello to everyone who views and replies to this post. I've recently been very active in my newly real estate investing journey, and I've came across a bump... I drove around neighborhoods (driving for dollars) and collected a good amount of addresses. the problem i am having is finding the owner of these properties. What source/site is best used for finding owners of properties ? I have heard of skip tracing and some good sites for that but when going to those sites, they need you to upload list with the owners name and information already on it, i need to find a good source to find who is ever has ownership of a certain property.. any suggestions would be great, thank you.
