@Jonathan Sachetti you could wait until it goes to auction, but then it will open things up to other investors. Depending on your market this could drive up the price.
If you are the only one negotiating with the seller, and they are obviously motivated to sell, there are options to staying or delaying the foreclosure. There should be contact information for the auction on who the trustee is, and if you can get an executed contract with the seller, this is usually enough to delay the auction. A hard money loan would be best if the auction is only 10 days away, if you don't have the cash on hand.
Another option that is a bit more of a "nuke it from orbit" option, is for the seller to start the paperwork for bankruptcy. This puts an automatic stay on the auction and gives the seller time to complete paper and title work to get to closing, and then the seller can dismiss the bankruptcy. For this tactic, I would talk with your title representative for details that work in your market.
Great find BTW; my recommendation is to not let it go to someone else and act quickly. If you feel in over your head, find a money partner that has more experience in your area.
