Looks like a nice example and I wish you the best with your sale but I think you might need to think about the current availability of this game and how that effects what you are asking for it. Like others have mentioned new Pro's can still be bought under 5K with free shipping.
I think you might need to prepare yourself for a bit of a loss with this title since you bought it NIB. I totally understand the priority of using the cash for a house but don't expect many bites at your asking price.
Like I said, best of luck. It's an awesome game and somebody will be happy to buy it from you at the right price.
