How to buy a house at a foreclosure auction: a beginner's guide with a pre-bid checklist
Updated · by the LowBaller team
To buy a house at a foreclosure auction, find the sale in county or trustee notices, research title and liens, bring the certified funds the sale requires, and bid only up to a maximum you set beforehand. If you win, you usually get the house as-is, with whatever surviving liens and occupants come with it.
Auctions produce real discounts, which is why they draw experienced cash buyers. Beginners lose money in predictable ways: a senior lien they did not know about, a redemption period, a house that needs twice what they budgeted. This guide covers how sheriff and trustee sales work, what to bring, what survives the sale, and a 10-point checklist to run before every bid.
How does a foreclosure auction work?
When a homeowner stops paying and does not cure the default, the lender forces a sale. The sale is public and announced in advance, through recorded notices, courthouse postings, newspaper ads and, in many places, an online listing. On sale day an auctioneer, a sheriff's deputy or a trustee reads the property, opens the bidding, and sells to the highest bidder.
The lender usually opens with a credit bid, often near what it is owed plus costs, without bringing cash. If nobody bids higher, the lender takes the house and it becomes bank-owned. If you outbid the lender, you buy the house, and the money pays off the foreclosing loan first, then junior liens, with any surplus going to the former owner.
Many sales get postponed or canceled at the last minute because the owner caught up, filed for bankruptcy or sold. Check the status the morning of the sale.
Sheriff sale vs trustee sale
Which one you face depends on your state. Judicial states run foreclosures through the courts, and they usually end in a sheriff's or referee's sale. Nonjudicial states use a deed of trust with a power of sale, so a trustee runs the auction without a lawsuit. Some states allow both.
| Feature | Sheriff sale (judicial) | Trustee sale (nonjudicial) |
|---|---|---|
| Who runs it | The sheriff, a referee or a court officer | A trustee named in the deed of trust |
| Court involvement | A judge orders the sale | No lawsuit, unless the owner sues |
| Typical timeline | Often many months or longer | Often a few months |
| Notice | Court filings plus published notices | Recorded notice of sale, posting and mailing |
| Confirmation after the sale | Some states require a judge to confirm it | Usually final at the auction |
| Owner redemption after the sale | More common | Less common |
What do you need to bring to a foreclosure auction?
Money first. Most foreclosure auctions take cashier's checks or other certified funds, not personal checks or a mortgage. Some want the full bid at the sale. Others take a deposit at the sale, often a percentage of the bid, with the balance due within a set number of hours or days. Online sales usually want a deposit before you can bid. Read the sale terms on the sheriff's, trustee's or auction platform's website.
If the terms allow, bring several cashier's checks in different amounts rather than one large one, so you can match your bid. Bring a photo ID, the exact name you will take title in, and your research file with the max bid for each property written down.
Know the schedule. In Texas, for example, nonjudicial sales happen on the first Tuesday of each month between 10 a.m. and 4 p.m. at the courthouse area the county designates, with notice at least 21 days before, under Texas Property Code section 51.002. Other states run sales weekly, monthly or online.
Check the postponement list that morning
Many sales are postponed or canceled on auction day. Check the trustee's or sheriff's list before you leave so you know which houses will actually sell.
Title risk: which liens survive a foreclosure auction?
A foreclosure generally wipes out liens junior to the loan being foreclosed, if those lienholders got proper notice. It does not wipe out senior liens, and some debts jump the line. Buying at a second-mortgage foreclosure, for example, means you take the house subject to the first mortgage.
| Lien | Usually survives? | Notes |
|---|---|---|
| Property taxes | Yes | Tax liens generally come ahead of mortgages; check what is owed at the tax collector |
| Senior mortgage (when a junior lien forecloses) | Yes | You buy subject to the first loan; read which lien is foreclosing |
| Junior mortgages and HELOCs | No, if properly notified | A missed notice can keep a junior lien alive |
| HOA or condo liens | Varies | Some states give part of an HOA lien priority over the mortgage |
| Federal tax liens | Can be discharged, with a catch | The IRS can redeem for 120 days or the state redemption period, whichever is longer |
| Municipal liens and code fines | Often | Water, demolition and code liens can have special priority under local law |
Redemption: can the old owner get the house back?
In some states, the former owner keeps a right of redemption after the auction. They can buy the house back by repaying the sale price plus interest and certain costs, within a period set by state law. During that window you may not be able to take possession, renovate safely or resell with clean title.
Other states end the owner's rights at the sale. Redemption rules differ between judicial and nonjudicial sales, and between mortgage foreclosures and tax sales. Look up your state on our foreclosure laws by state pages, such as Texas foreclosure law or Michigan foreclosure law, and confirm with a local real estate attorney before your first bid.
The 10-point pre-bid checklist
Run this on every property, every time. If you cannot check an item, lower your max bid or skip the house.
| Check | Where to find it | Why it matters |
|---|---|---|
| 1. Sale terms | Sheriff, trustee or auction site | Deposit size, certified funds and when the balance is due |
| 2. Which lien is foreclosing | Notice of sale and recorded loans | A junior lien sale leaves the first mortgage in place |
| 3. Full title search | County recorder or a title company | Finds every recorded loan, lien and judgment |
| 4. Property taxes owed | County tax collector | Unpaid taxes usually survive the sale |
| 5. HOA and municipal liens | HOA, city and water department | Some have priority under state or local law |
| 6. Federal tax liens | County recorder | Can carry an IRS redemption right |
| 7. Redemption rights | State law and the sale notice | Decides when the house is truly yours |
| 8. Occupancy | Drive-by, utility signs, mail | Occupied houses need a legal possession process |
| 9. Exterior condition and repairs | Drive-by and permit history | You usually cannot see inside, so budget a cushion |
| 10. Sale status that morning | Trustee or sheriff postponement list | Many sales are postponed or canceled |
How to set your max bid
Set the number at home, not in the room. A simple version uses the 70 percent rule: take the after-repair value, multiply by 0.70, then subtract repairs and any liens that survive the sale. Example: a house worth $280,000 after repairs, needing about $40,000 of work, with $6,000 in unpaid property taxes that survive. 70 percent of $280,000 is $196,000. Minus $40,000 is $156,000. Minus $6,000 is a max bid of $150,000. The lowball offer calculator runs this math for you.
If the lender's opening credit bid is already above your max, let it go. There is often a better deal one step earlier: owners with a scheduled auction carry the top weight in LowBaller's ranking model (40 points), and buying from them before the sale gets you an inspection and a normal title search. The pre-foreclosure pages show where those owners are, and how to buy a foreclosed home compares every stage.

How to buy a house at a foreclosure auction, step by step
Attend one or two sales as a spectator first. Then follow these steps for every property you bid on.
- 1
Learn your state's process
Find out whether your state uses sheriff sales, trustee sales or both, and whether owners can redeem after the sale.
- 2
Find upcoming sales
Check the sheriff's sale list, trustee notices recorded at the county, newspaper legal notices and county auction sites.
- 3
Shortlist and drive by
Pick a handful of properties, drive by each one, and note condition and signs of occupancy without entering or disturbing anyone.
- 4
Run the 10-point checklist
Research title, taxes, HOA and municipal liens, federal tax liens and redemption rights. Pay a title company if you are unsure.
- 5
Set a max bid for each house
Use after-repair value, repairs and surviving liens. Write the number down before sale day.
- 6
Get certified funds ready
Get cashier's checks or the required deposit, following the sale terms exactly.
- 7
Confirm the sale is still on
Check the postponement list the morning of the sale.
- 8
Bid, pay and record
Bid up to your max and stop. If you win, pay on time, get the sheriff's or trustee's deed, and record it at the county.
- 9
Take possession legally
If the house is occupied, use your state's legal process. Then change the locks, insure the house and start repairs.
Frequently asked questions
Can a beginner buy a house at a foreclosure auction?
Yes, but beginners should start slowly. Attend a few sales without bidding, learn your state's rules, and run a full title and lien check on every property. Bid only with cash you can afford to tie up, on houses you have driven by, and stop at a maximum you set before sale day.
Do you need cash to buy a house at a foreclosure auction?
Usually, yes. Most foreclosure auctions require cashier's checks or other certified funds, either the full bid at the sale or a deposit with the balance due soon after. Traditional mortgages rarely close fast enough. Many buyers use cash or private money arranged in advance, then refinance after they own the house.
What happens after you win a foreclosure auction?
You pay the balance by the sale's deadline, then receive a sheriff's or trustee's deed, which you record at the county. In some states a judge must confirm the sale first, and some give the former owner a redemption period. If the house is occupied, you follow your state's legal process to take possession.
Can you inspect a house before a foreclosure auction?
Usually not inside. The owner still holds the house until the sale, and entering without permission is trespassing. You can drive by, look at the exterior, check permit and code records, and review old listing photos. Budget a repair cushion for what you cannot see, because the house is sold as-is.
What is the opening bid at a foreclosure auction?
The opening bid is usually the lender's credit bid, which is often close to what the borrower owes plus fees and costs. The lender can bid that amount without bringing cash. If no one bids higher, the lender takes the house and it becomes a bank-owned property listed later with an agent.
Can the previous owner get the house back after a foreclosure auction?
In some states, yes. A statutory right of redemption lets the former owner buy the house back after the sale by repaying the price plus interest and certain costs, within a period set by state law. Other states end the owner's rights at the auction. Check your state's rules with a local attorney.
