What's a good wholesale profit/PM

[James Phillips]

I looked up what the winning bid for a HUD property was and it was about $131K, they are selling for $157K. The will have owned the property for about 1 month (the auction was 11/28)

They claim its a "clean up and sell" type property (painting too, but no major problems), and if that's the case I'd be willing to buy at $141K, but that still seems like a huge profit margin for 1 month.  I want to make a reasonable counteroffer, but I don't want to sour the deal either.  

Any help would be appreciated!
