Good chances are that if a property is publicly listed, the seller is in the mindset to sell at the right number. 

@Matt DornakWhat is the specifics- If it’s selling a property to buy another there could be programs that work but other than that, no owner occupied loan to delay financing

Want to sell my apartment building by owner best course of action

Buy low and sell high.

Get an attorney to review the claims process typically they expire if they do not pursue them after a period of time2.

We have a small mobile home park in Indiana that we are in the process of stabilizing.

From what I have read, the main benefit is early access to MLS for purchasing homes and saving on commission costs while selling homes.This leads to two questions: - Is simply having early access to new listings worth $600, or is it only worthwhile if I plan on flipping and selling a property on my own?

This will depend on the lender and their model (whether they're selling or holding this loan). 

That's a great question, but it's a loaded one.What aspects of the process are you most interested in?

The wholesaler probably doesn’t believe the deal will close, just wants a contract from you and sellers failure to sell as agreed so he could establish the lost profit due to seller’s non performance and sue for the $15k differential which is easier to win rather than specific performance.
