Foreclosure
They are two different stages with two different sets of options, and confusing them costs homeowners money every year.
Here is what separates them, what you can still do at each point, and what happens to any money left over once a property sells.
Stage one
Pre-foreclosure begins when you fall far enough behind that the lender records a formal notice, usually a Notice of Default. In most states that filing is a public record, which is why homeowners in default suddenly receive a great deal of mail.
You still own the property. You can still sell it, refinance it, reinstate the loan by clearing the arrears, negotiate a modification, or arrange a short sale. Nothing has been taken from you yet.
Timelines vary by state. In California, for example, this stage runs at least three months before a Notice of Trustee Sale can be recorded, and that notice sets an auction date roughly three weeks out. Judicial-foreclosure states move differently and usually more slowly.
Stage two
Foreclosure is the sale itself. In non-judicial states it happens through a trustee rather than a courtroom and moves faster than most people expect; in judicial states it runs through the court.
At the auction the property is sold to the highest bidder. Ownership transfers. The proceeds pay the lender, then any junior liens, in order of priority.
And here is the part almost nobody is told: if the property sells for more than the total owed, that leftover money does not belong to the lender or to the county. It belongs to the former owner.
What to do
The part people miss
A lender forecloses to recover what it is owed, not to make a profit. If the debt was $310,000 and the property sold for $375,000, the extra $65,000 is surplus. After junior liens are satisfied, whatever remains is held for the former owner.
It sits with the trustee or the county. Nobody is strongly motivated to find you, and if you have moved since the sale, the notice they mail may never arrive. Left long enough, in many jurisdictions it reverts to the government permanently.
If a foreclosure or tax sale has already happened, there may be money left over that belongs to you. The search is free and you owe nothing unless we recover funds.
