What the posting actually means
A posted foreclosure sale is not a warning shot you can file under “later.” It is the public notice that the trustee is scheduled to sell the house. You still have title until that sale happens. That is the window where you can still sell.
After the sale, the buyer is the lender or a bidder. You are not in the deal. People in denial treat the posting like junk mail. It is the calendar.
If this is your house and you want to sell it, that is a purchase. We are the buyer. How we buy.
