Based on that I don't get the impression he's desperate to sell.Being that this isn't a perfect world, which would you prioritize in this scenario?

Don't rush into a deal out of desperation...  

I do not think any of them desperately need a large check(like they would get from a traditional sale), but I would want to pay them for the house within a year or earlier if possible.

When you focus on one lead at a time it turns into desperation to make that into a deal.

Of course, they ask me to look at the "built-in equity" that I am getting because their seller is desperate.

I'm not desperate, I do have a job.
