How to Buy a Foreclosure: Pre-Foreclosure, Auction, or REO

To buy a foreclosure, you choose one of three purchase channels — pre-foreclosure, public auction, or bank-owned resale — then meet the money, documentation, and due-diligence requirements that apply to that channel. Foreclosed homes can sell below market value, but they carry risks a standard purchase does not: unknown property condition, liens that may survive the sale, and post-sale rights that can let the former owner or the IRS reclaim the property.

The Three Ways You Can Buy

Foreclosures reach buyers at three different stages, and the stage decides almost everything about the transaction.

Pre-foreclosure or short sale. The homeowner has defaulted but the property has not yet gone to auction. You buy directly from the owner, and if the sale price is less than the mortgage balance, the lender has to sign off. That version is called a short sale. The process looks a lot like a normal home purchase, inspection included.

Public auction. A trustee or sheriff sells the property at a courthouse or through an online bidding portal. Auctions are fast, almost always require cash on the spot, and rarely allow an interior look beforehand. The price can be lower, and the risk is higher.

Bank-owned (REO). If no third-party bidder outbids the lender at auction, the lender takes the property and lists it, usually through a real estate agent. REO sales run through a standard escrow closing with inspection contingencies, so they feel closest to a conventional purchase.

Money and Paperwork You Need First

If You Are Paying Cash

You need a proof-of-funds letter from your bank or another financial institution stating your liquid balance and confirming you can cover the purchase price. Sellers and auction officials generally want the letter dated within 30 days of the transaction.

If You Are Financing

A standard mortgage pre-approval may not be enough. Foreclosed homes often need significant repairs, and conventional mortgages typically will not fund a property in poor condition. Three programs are built for this situation.

The FHA Limited 203(k) lets you finance up to $75,000 in repair costs on top of the purchase price and covers non-structural work like flooring, plumbing, or appliances.¹
The FHA Standard 203(k) covers major structural work — additions, foundation repairs, gut renovations — as long as repairs exceed $5,000 and the total property value stays inside FHA mortgage limits for your area.¹
The Fannie Mae HomeStyle Renovation loan is a conventional option that rolls renovations into the mortgage for one- to four-unit primary residences, one-unit second homes, or one-unit investment properties. Renovation costs are capped at the lesser of the cost estimate or a percentage of the completed value, and the total loan cannot exceed Fannie Mae’s maximum mortgage amount for the area.²

Your pre-approval letter should state the maximum loan amount and confirm your credit standing. If you plan to use a renovation loan, ask the lender to name that program in the letter so the seller knows the financing is real.

Payment and Registration at Auction

Foreclosure auctions almost universally require cashier’s checks or cash. Personal checks and credit cards are not accepted. Cashier’s checks are usually made payable to the trustee, the clerk of court, or the entity conducting the sale, so confirm the exact payee before auction day. Bring a valid government-issued photo ID.

Registration rules vary by jurisdiction. Some auctions want forms declaring your intent and eligibility, and a few charge a non-refundable deposit just to bid. Check the specific rules well ahead of the sale date. Showing up unprepared will disqualify you.

Run a Title Search Before You Commit

Order a preliminary title report from a title company. It searches public records for existing claims against the property: unpaid property taxes, secondary mortgages, mechanics’ liens, easements, and other encumbrances.

Not every lien disappears in foreclosure. The rule is priority by recording date. Liens junior to the foreclosing lender’s mortgage are typically wiped out by the sale. Liens senior to it survive and become your responsibility as the new owner.

Federal Tax Liens

Federal tax liens follow the same priority framework with an added wrinkle. If the IRS recorded its lien notice before the foreclosing lender’s mortgage was recorded, the tax lien survives the foreclosure and stays attached to the property.³ A federal tax lien is not valid against a prior recorded mortgage until the IRS files notice, so the recording date of that IRS notice decides priority.⁴

Even when a senior lender’s foreclosure wipes out a junior federal tax lien, the IRS keeps a right to redeem the property for 120 days after the sale, or longer if state law provides.⁵ Inside that window, the IRS can buy the property from you by paying what you paid at the sale. It is uncommon but real, and a thorough title search will surface any recorded IRS lien notices so you can weigh the risk before bidding.

Title Insurance

After the search, a title insurance policy protects you from defects the search did not catch: forged documents in the chain of title, undisclosed heirs, recording errors. It is a one-time cost paid at closing. Title insurance can be harder to arrange for auction purchases because you may not have time to finish the search before the sale, which is one reason auctions carry more risk than REO or pre-foreclosure deals.

Buying in Pre-Foreclosure

A pre-foreclosure purchase happens after the owner has defaulted but before the auction. You negotiate directly with the homeowner. If the agreed price is less than the mortgage balance, the lender also has to approve the sale, which makes it a short sale.

Short sales take longer than other foreclosure purchases. The lender reviews your offer, the owner’s financial hardship, and the property’s appraised value before deciding whether to accept less than what is owed. That can take weeks or months.

The main advantage is access. You can typically walk through the property with an inspector, negotiate on repairs or price, and secure title insurance before closing. The trade-off is the slower timeline and no guarantee the lender will say yes.

Bidding at a Foreclosure Auction

How the Bidding Runs

Public auctions take place at a designated location, often the steps of a county courthouse, or through an online portal. After registering and presenting ID and cashier’s checks, you bid at the increments the auctioneer sets. The lender usually opens with a credit bid: the amount it will accept, which may be the full loan balance plus fees and interest, though lenders sometimes set a lower number to draw third-party bidders. If no one outbids the lender, the property becomes REO.

Each bid is treated as an irrevocable offer. Once the auctioneer announces the sale is final, the winning bidder is under a binding contract. You sign a certificate of sale on-site and hand over the full bid amount, or the required deposit, in cashier’s checks. Any remaining balance is typically due within 24 hours or by a deadline the court or trustee sets.

No Interior Inspection

The biggest risk at auction is that you almost certainly cannot see the inside first. The former owner or a tenant may still be living there, and the selling entity has no obligation to arrange access. You buy as-is, whatever the condition, including damage invisible from the curb. Mold, foundation damage, faulty wiring, and missing fixtures are common in distressed properties and can add tens of thousands of dollars to your costs.

Before bidding, drive by, research the tax and permit history, and pull the preliminary title report. That does not eliminate the risk. It shrinks it.

After You Win

Once your payment clears, the trustee or sheriff prepares a deed, commonly called a trustee’s deed or sheriff’s deed, transferring ownership to you. Recording that deed can take anywhere from about 15 days to several months depending on the jurisdiction. Until it is recorded, your ownership may not appear in public records, so hold onto your certificate of sale and payment receipts.

Buying a Bank-Owned (REO) Home

When no one outbids the lender at auction, the property becomes Real Estate Owned. The lender typically hires a local real estate agent to list it on the MLS or on the lender’s own online platform. To make an offer, you generally work with a real estate agent who submits your bid through the lender’s system.

Once the lender accepts, you sign its purchase addendums. These are lengthy and tend to shift most liability for property condition and title defects onto you. Read the timelines carefully. They set strict deadlines for inspections, financing contingencies, and closing, and missing one can let the lender cancel the contract and keep your earnest money.

Use the Inspection Window

REO contracts typically include an inspection contingency of about 7 to 10 days. The bank will not make repairs — REO properties are sold as-is — but the inspection gives you the information to price the repairs, renegotiate, or walk away before the contingency closes. Always use this window. Skipping inspection on a foreclosure is one of the most expensive mistakes a buyer can make.

Closing

Escrow and closing follow a path similar to a traditional home sale. A neutral escrow company handles the exchange of funds and makes sure both sides meet their contractual obligations. Do a walkthrough before closing to confirm the property’s condition has not changed since your inspection; vandalism and further deterioration happen on vacant homes. Closing ends with the recording of the deed, which officially transfers title from the lender to you.

Redemption Rights and Tenants Already Living There

State Redemption Periods

In roughly half of all states, the former homeowner has a legal right to reclaim the property after the sale by paying the full sale price plus interest, fees, and certain expenses the buyer incurred. This is a statutory right of redemption, and the window runs from as short as three months to as long as one year depending on the state. During that period, your ownership is not fully final. If the former owner comes up with the money, you get yours back but lose the property.

Check whether your state has a redemption period and how long it lasts before you bid. In states with long redemption windows, you may not be able to resell or refinance until the period expires, which ties up your capital.

Federal Redemption

Even in states without a general statutory redemption, the federal government has its own redemption right when a federal tax lien was attached. The IRS can redeem the property within 120 days of the sale, or within any longer period allowed under state law, by paying what you paid at auction.⁵ If it does, the IRS records a certificate of redemption and title transfers to the United States.

Tenant Protections

If tenants are living in the property under a legitimate lease, federal law limits how quickly you can require them to leave. The Protecting Tenants at Foreclosure Act requires the new owner to give bona fide tenants at least 90 days’ written notice before requiring them to vacate.⁶ If the lease extends past those 90 days, you generally have to honor the remaining term, unless you plan to occupy the home as your own primary residence, in which case the 90-day notice applies no matter the lease length.

To qualify, the tenancy has to meet three conditions: the tenant is not the former borrower or an immediate family member of the former borrower, the lease is the result of an arm’s-length transaction, and the rent is at or near fair market value (or reduced because of a government subsidy).⁶ Some states set longer notice periods or add protections on top of the federal minimum.

What You Owe After Closing

Transfer taxes — fees charged by state or local governments when property changes hands — typically run from a fraction of a percent up to about 2% of the sale price, depending on your jurisdiction. You will also pay a recording fee to file the new deed with the county recorder’s office, usually a modest charge.

If the property is occupied by the former owner or by someone who does not qualify as a bona fide tenant under the federal rules above, you have to go through the formal eviction process. You cannot change the locks or shut off utilities to force someone out. That is illegal in every state. Eviction timelines vary by jurisdiction but generally require filing a court action and waiting for a judge to issue an order, which can take anywhere from a few weeks to several months.

Budget for immediate property needs. Foreclosed homes often sit vacant for months, and common issues include winterization damage, plumbing failures, pest infestations, and deferred maintenance. If you financed with an FHA 203(k) or a HomeStyle Renovation loan, the repair funds are built into your mortgage, but the work has to begin promptly and follow the lender’s draw schedule.¹
