"Subject to" vs "Wraps"

[Gerald David]

I live in an area with a small population. I need to add more "tools" to help make deals happen. With that said, I'd like to add deals like "subject to" and/or "wraps" to my current tools of wholesaling/buy & hold.

My question: what are the differences are between acquiring a property "subject to" vs using a "wrap". Why would I want to do one over the other?
