I went to one posted by @Darren Sager here on BP and it was excellent.

That cracked me up and I said ok you win, I'll take one third and you take two thirds of the difference.

First, I recommend you concentrate on properties that YOU find attractive as an Investor, rather than trying to work out why other Buyers might like to pay you more than you Contracted, for a property that hasn't particularly appealed to the Investor-in-you in the first place.Consequently, finding a Lender who will "cover" you by lending the money to you IF you can't track down another cash Buyer before "closing" time, becomes a win-win for both Plan A (Wholesale) and Plan B (Buy)! 

A win-win example I had to share.  

Thank you, Micah, that's an excellent strategy. 

I had also prepared to offer the occupant cash after moving out rather than have to go through the eviction process to create a sort of win-win, rather than a loose-loose (where the angry occupant is forced out and destroys the house along the way).

Win-win. 

You're right, my response rate is excellent as a percentage of my mailers.

Tenant will prove dirty apartment at move in with pictures ,call the tenant apologize for the misunderstanding, return the money and move on; Tenant  will most likely win in court and you will most likely pay deposit plus penalties x3, plus your lawyer's inflated fees good luck
