Just finished driving for dollars. Any tips appreciated

[Ryan Howard]

So I just got done driving around two neighborhoods in one of the best school districts in my area and found 9 vacant properties. My intentions are to wholesale most of them and the best two out of the bunch try and secure financing to fix and flip. I've read multiple posts about finding the owners of vacant properties and have came across a bunch of different methods. Does anyone have any advice on the order in which I should start to try and find the owners of these vacant properties from best to worst? Thanks in advance.
