Best lead source for flip?

[Cody Wirz]

What are the best lead sources to get a rehab to flip (Dallas area)? I am still new to flipping but I have had luck in having my first two deals "fall into my lap". Now I am actively looking for property to rehab/flip, but I can't find ANY distressed properties to rehab. I have reached out to realtors I know, recently signed on for wholesalers newsletter, checked MLS (REO prices are almost market price!), and had no luck at the most recent courthouse steps county auction. Where are other sources I can find good leads? Thanks for any input.
