I buy in the 220-260k range.

Look for motivated sellers off market and market via cold calling and or direct mail, geofencing, advertising and the like.A good wholesaler is as @Ericka Parrott mentioned, direct to seller, did good underwriting and can deliver an actual "Deal" whether buy and hold or flip. 

What would I need to do to structure the note in order to have a note buyer come in and buy the note or buy a partial enough to pay off the 215k at closing and still have some difference coming to me or the note revert back to me after the partial was paid for. 

Are the other properties you're buying in/around Macon? 

We ran out of time which caused us to buy a couple properties we probably shouldn't have at the bottom of our exchange list.The better ones were sold before we could buy them. 

One thing you might do is sell your more expensive properties and buy less expensive ones. 

Quote from @Alex Spivey: I want to start renting as soon as I can so does anyone have adviceYou want to find a place to rent and occupy, or you want to buy an investment that you can rent to others?

that OR consider buying a property you could short-term rent to people who literally just want to visit the casino if it's a large/decent one. 

Assuming the area checks out, I’d rather buy in a high price area that has little to no cash flow rather than an area that has cash flow but lower price.  

I've worn three hats in the seller financing world (as a property buyer, as a property seller offering terms, and as an investor that buys seller financed note).
