Wholesaling Contract: When to Take To Title Company

[JORDAN Z WILEY]

So I know this is a very newbie question, but I was wondering about the logistics of taking the contract to the title company. Once I get an a-b contract signed with a seller do I then take it over to the title company right away, then find a buyer, sign an b-c contract  and take that to the same title company separately? Or do I get both a-b and b-c contracts signed and then take them to the title company at the same time? Thanks in advance.
