I am sure the answer is "it depends" hence the term "creative financing" but was hoping people might offer a few examples to help me think more about how i might approach deals where the seller is motivated and the property as been listed for a long time. 

How is general property appreciation there?

He came to me to see if   I would be open to co-owning the property.

I am willing to offer 5% ownership of any properties I purchase with them as co-signers.

Essentially how do we separate from partnering on each property when the time comes? 

BS, those same deals stayed on your marketplace for months after you said they were taken down, and they were not even available anymore (a "principal wholesaler" in your marketplace even told me one of the properties was no longer available, and your team was CC'd on that email!)

Ordering an appraisal for such a small property would be silly. 

When I did underwriting, since a portion of the insurance costs and property taxes are collected at closing, I reduced those from the first year of expenses.

There are different types of investments like residential properties, commercial real estate, or short-term rentals.

Well we'd need a lot more details on the property before anyone can help.
