A foreclosure sale is a public auction where a lender sells a borrower’s property to recover an unpaid mortgage balance. How a foreclosure sale works depends first on the state: in about half the country the lender must sue and get a court order before selling, while in the rest the lender (through a trustee) can sell under a “power of sale” clause in the mortgage without going to court. Either way, the sequence is the same at its core — default, required notices, a public auction, payment, and a recorded deed that transfers ownership to the winning bidder.
Judicial and Non-Judicial Sales
In a judicial foreclosure, the lender files a lawsuit, the borrower has a chance to raise defenses, and a judge oversees each step, including confirming the sale afterward. In a non-judicial foreclosure, the lender or a trustee follows a procedure laid out in state law and in the mortgage or deed of trust itself, with no court action.
Roughly half of states primarily use judicial foreclosure and the rest primarily allow non-judicial sales, though many states permit both depending on the circumstances. Non-judicial foreclosures tend to move faster because they skip the court calendar. Judicial foreclosures give borrowers more procedural protections.
Notices Required Before the Auction
Before an auction can happen, the lender or trustee has to give formal notice. For federally related mortgages, the notice must include the property address and legal description, the date the borrower fell behind, the date, time, and location of the sale, and the deposit amount required of bidders.
The notice is usually served in several ways at once:
- Publication in a local newspaper, often once a week for three consecutive weeks before the sale date.
- Recording in county property records so junior lienholders and other interested parties can find it.
- Mailing to the homeowner by certified mail or personal service.
- Posting on the property itself and in a public building such as a courthouse, in many states.
If any of these steps is skipped or done wrong, the sale can be voided. A homeowner facing foreclosure should check that every required notice was properly delivered, because a procedural misstep by the lender may be grounds to challenge the sale in court.
Finding and Registering for the Auction
The list of properties scheduled for sale comes from the county sheriff’s office, the trustee, or an online auction portal. Each listing includes the assessor’s parcel number, which lets you look up the property’s location, size, and tax history.
Auctions run on cash or cash equivalents. Bidders typically bring cashier’s checks or certified funds, and many jurisdictions require a deposit before you can register. You will also need identification and a tax identification number. Registration procedures differ by location, so check the specific requirements published in the notice of sale.
Properties Sell As-Is
Foreclosure properties are sold in current condition with no warranties from the lender or trustee. You generally cannot inspect the interior beforehand, and you have no legal claim against the seller for defects you find later. The one exception is if someone knowingly concealed a material problem. That means the winning bidder can inherit serious repair costs — roof damage, foundation issues, or environmental contamination — with no recourse. Drive by the property if you can and research its permit and code-violation history before bidding.
Liens That Survive the Sale
Not every lien is wiped out at auction. The foreclosure eliminates the mortgage being foreclosed and any junior liens (second mortgages, judgment liens, and other claims recorded after the foreclosed mortgage). Liens senior to the foreclosed mortgage stay attached to the property, and the buyer takes it subject to them. Common survivors include:
- Property tax liens, which almost always take priority over all other liens.
- Special assessment liens for infrastructure improvements like roads or sewers, often at the same priority as property taxes.
- Federal tax liens, which give the IRS a 120-day right to redeem the property after the sale (or longer if state law allows a longer redemption period).
- Code enforcement liens for demolition, debris removal, or environmental cleanup.
Search the county recorder’s office and tax assessor’s records before you bid. Subtract the total of any surviving liens from your maximum bid to find your true cost of acquisition.
How the Bidding Works
The auctioneer opens by reading the property description and the terms of sale. The foreclosing lender then places the opening bid, called a “credit bid.” Instead of putting up cash, the lender bids against the debt it is owed. The lender can credit-bid up to the full amount of the outstanding loan balance plus accrued interest, fees, and foreclosure costs, but it may strategically bid less than that. If the lender bids low and no one else bids, the lender acquires the property at the lower price.
Private bidders then compete by offering higher amounts, usually in increments set by the auctioneer, commonly a few hundred to a thousand dollars per raise. You signal a bid by raising your hand or a numbered paddle. Each verbal bid is a binding commitment to purchase at that price if no one bids higher. The auctioneer repeats the highest bid, gives other bidders a chance to respond, and declares the property sold.
If no outside bidder exceeds the lender’s credit bid, the property reverts to the lender and becomes what the industry calls “real estate owned,” or REO. The lender then typically lists it for sale through a real estate agent like any other property.
Payment, Confirmation, and Deed Transfer
The winning bidder has to present full payment or the required deposit in certified funds right after the sale. An on-site memorandum of sale serves as a receipt and confirms the purchase price.
Court Confirmation in Judicial States
In judicial-foreclosure states, a judge has to confirm the sale before it becomes final. That confirmation period lets the court verify the procedures were followed and gives interested parties a chance to object. The timeline varies widely: roughly 30 days in some states, 60 to 90 days in others, and as long as six months in a few jurisdictions.
The Deed and Recording
Once the sale is confirmed, or immediately in non-judicial states, a deed is drafted. It’s called a trustee’s deed in a non-judicial foreclosure and a sheriff’s deed in a judicial one. The deed is recorded in the county land records, officially transferring ownership. Delivery of the deed terminates the former owner’s legal interest in the property. The buyer pays recording fees and any transfer taxes, which vary by jurisdiction.
Redemption Rights That Can Unwind the Sale
Many states give the former homeowner a statutory right of redemption, a window after the sale in which they can buy the property back by paying the sale price plus the buyer’s costs and interest. This is separate from the equitable right of redemption, which lets a borrower stop a foreclosure before the sale by paying off the entire debt.
The length of the statutory redemption period varies dramatically by state, from none at all to several years. Some states offer a shorter period for abandoned properties. During the redemption period the buyer’s ownership is not fully settled: if the former owner redeems, the sale is effectively reversed. Anyone bidding in a state with a long redemption window should factor that risk into their price.
The federal government also has redemption rights. When a foreclosure eliminates a junior federal tax lien, the IRS has 120 days from the date the deed is recorded, or the state-law redemption period if that’s longer, to redeem the property by paying the buyer the sale price plus certain costs.
Deficiency Judgments and Surplus Funds
When the sale price falls short of what’s owed, the shortfall is called a deficiency. In many states the lender can sue the former homeowner for that amount through a deficiency judgment. Roughly a dozen states, including Arizona, California, Minnesota, Nevada, Oregon, and Washington, have anti-deficiency laws that restrict or prohibit these claims, particularly for purchase-money mortgages on primary residences. Even where deficiency judgments are allowed, the lender usually has to file within two to four years after the sale, and the borrower can sometimes argue that the property’s fair market value was higher than the sale price to reduce the deficiency amount.
When the sale price exceeds the total debt plus foreclosure costs, the excess is called surplus funds, and the former homeowner has a legal right to claim them. Getting them usually means filing a petition or claim with the court or the office holding the funds. A former owner should check with the court clerk or trustee’s office to find out whether surplus funds exist and what paperwork is required. There is usually a deadline; miss it and the money may be forfeited to the state.
What Happens to People Living in the Property
If tenants are living in the foreclosed property, federal law gives them significant protection. The Protecting Tenants at Foreclosure Act requires the new owner to give any legitimate tenant at least 90 days’ written notice before requiring them to move out. A tenant qualifies for protection if the lease was an arm’s-length transaction (not with the former owner’s family), was entered into before the foreclosure notice, and requires rent that is not substantially below market.
Tenants with a lease that extends beyond the 90-day notice period can generally stay through the end of the lease. The exception: if the new owner intends to move into the unit as a primary residence, the owner can terminate the lease with 90 days’ notice even if time remains. The PTFA applies nationwide but does not override state or local laws with longer notice periods or additional protections.
Former owner-occupants don’t have the same federal protections. After the notice-to-vacate period, which varies by state from a few days to 30 days, they must leave or face a formal eviction lawsuit. If they don’t move out, the new owner files an eviction action (sometimes called an unlawful detainer) in court to get an order for removal.
