The courthouse steps have minted and broken fortunes. A sheriff sale can hand you a property at 40% below market — or saddle you with a crumbling shell carrying a half-million in undisclosed IRS liens. The difference between those two outcomes is almost entirely pre-auction research.
What a sheriff sale actually is
When a property owner defaults on their mortgage and the lender forecloses, the court orders the property sold at public auction to recover the debt. The local sheriff's office runs the sale. Unlike a tax lien auction — where you're buying a lien — at a sheriff sale you're buying the property outright. Subject to whatever encumbrances survive the sale.
That last phrase is the entire game. "Subject to whatever encumbrances survive" is where money is won and lost.
What gets wiped out at sale
Generally, the foreclosing lien (the mortgage being foreclosed) and all junior liens get wiped out. But "generally" is doing a lot of work in that sentence. What actually survives depends on the state, the type of lien, and the notice procedures the foreclosing party followed.
Liens that commonly survive sheriff sales:
- IRS federal tax liens (subject to the 120-day redemption right)
- State tax liens (varies by state)
- Senior mortgages (if you're buying at a junior foreclosure)
- HOA super-liens in certain states
- Municipal liens for water, sewer, or code enforcement
- Easements and restrictive covenants
If any of those exist and you didn't know, they're now your problem. A $180,000 courthouse win can become a $340,000 loss in one sentence of a title report you didn't pull.
The four-step pre-auction checklist
1. Pull the title report
This is non-negotiable. Order a full title search — not an owner's search, a lender's search. You want every recorded document against the parcel for at least 30 years. If you're bidding at a junior foreclosure, you need to know what's senior and what will survive.
2. Confirm which foreclosure is being prosecuted
Look at the specific filing. What's being foreclosed? First mortgage? Second? HOA? The answer tells you which liens survive. A foreclosure on a $50,000 HOA assessment is a very different deal than a foreclosure on a $380,000 first mortgage.
3. Inspect the property — from the outside
You won't get access to the interior. That's the reality of buying at auction. But you can drive by, pull satellite imagery, check the roof, look for fire damage, verify occupancy. If you can see it from the street, document it. Every surprise reduces your margin.
4. Set your max bid and walk away from anything else
Your max bid should be: conservative ARV minus rehab estimate minus carrying costs minus your required profit margin minus a contingency. Write it down. Don't exceed it — not by a dollar, no matter how many underbidders drop out.
Auction day mechanics
Show up early. Confirm the parcel you want is actually being sold — last-minute withdrawals and bankruptcy stays happen constantly. Bring certified funds in the amount required by your county (typically 10% of the bid, due immediately, with the balance within 30 days).
Stand somewhere you can see the auctioneer and the other bidders. Bid with clear, visible signals. If you win, be ready to pay and sign paperwork on the spot. If you lose, congratulate yourself for sticking to your number — there's another auction next month.
The bidders who consistently profit at sheriff sales have already done 95% of their work before the auction starts. The day itself is just execution.
After you win
Your work isn't done. Depending on the state, you may face a statutory redemption period — a window during which the original owner can redeem the property by paying you back plus statutory interest. During that window, you typically can't take possession or begin major renovations. Plan your rehab timeline accordingly.
You'll also need to address occupancy. If the former owner or a tenant is still in the property, you'll need to pursue a formal eviction — even though you're now the legal owner. Budget time and legal fees for this. It frequently takes 30-90 days.
When sheriff sales make sense
This channel rewards investors who have cash on hand, understand local title law, and can move quickly. It punishes everyone else. If you're still learning the basics of real estate investing, spend six months with pre-foreclosures and short sales first. Build your title-reading muscles. Then come to the courthouse.
When the research is done and the numbers work, a sheriff sale can be the best deal you'll ever make. The discipline is in recognizing that almost none of the listings will clear that bar — and being comfortable leaving empty-handed when they don't.
