What is a pre-foreclosure?
A pre-foreclosure is the period after a lender has filed a public notice of default or lis pendens — indicating the borrower has missed payments — but before the foreclosure sale or auction has occurred.
Foreclosure is a legal process, not a single event. The pre-foreclosure window begins when the lender takes its first formal legal step: in most states, a Notice of Default (NOD) or a lis pendens filing with the county court or recorder. This notice is a public record, which is why it's identifiable in county data.
The length of the pre-foreclosure window varies by state and loan type. In judicial foreclosure states (where the foreclosure goes through the courts), the process can take 18 months or more. In non-judicial states with a power-of-sale clause, it can be as short as 90 to 120 days. This timeline determines how much runway a seller has to cure the default, sell, or refinance.
For buyers and investors, the pre-foreclosure window represents an opportunity to purchase before the property goes to auction — where title complications, deferred maintenance, and competitive bidding can add friction. A homeowner in pre-foreclosure may prefer a direct sale that lets them walk away with some equity and avoid a foreclosure on their credit record.
Identifying pre-foreclosure properties requires access to county court filings (lis pendens) or recorder notices (NOD/NOS — Notice of Trustee's Sale). These are distinct from the parcel record itself. Tracts focuses on the parcel layer — ownership, tax status, and mailing address — which complements pre-foreclosure notice data when you need to reach the owner of a property in default.
