Wholesaling Advice - Orlando, FL

[Alex Zynski]

About to begin my journey wholesaling in the Orlando area, preferably south-east to north Orlando. Have a list of cash buyers from cash bought property tax rolls, bandit signs, and the connectedinvestors website. 

Can anyone explain how they began wholesaling with no strong connections and also what kind of marketing for feasible properties(leads) was most successful? Planning on heading to the County Clerk to dig up targeted marketing prospects, any advice? Did you give sellers a non-refundable deposit?

All, harsh constructive criticism is welcome!
