Best way to find Cash Buyers in Columbus Ohio

[Christa Hegedus]

Hi everyone, I am virtually wholesaling in the Columbus Ohio region. My business is starting out with on-market deals and then using those profits to fund marketing efforts for off market. 
For the initial topic of On market wholesaling; what specific facebook groups, area of craigslist, and any other sources might I find cash buyers for these potential deals?

I've already found a few cash buyers via google ads who will buy on market deals so it is possible in this market (unlike Tampa, FL where I just moved my business away from since its so tough). Just want to get more ideas on where else I can find cash buyers. Thank you :)
