How to Buy a Foreclosure or Tax-Sale Property in Allegheny County
By Luke Petrozza · Pittsburgh investor · 7 min read
Tax sale and foreclosure properties are some of the cheapest entry points in the Pittsburgh real estate market. An Allegheny County tax sale property in McKees Rocks or McKeesport with $8,000 in delinquent taxes can clear at sheriff's sale for under $25,000. The catch is that Allegheny County runs its process differently from most Pennsylvania counties, and buyers who do not know the mechanics before they bid make expensive mistakes.
Here is how it actually works, what to watch for, and what to do before you raise your virtual hand.
How Does Allegheny County Differ From the Rest of Pennsylvania?
Most Pennsylvania counties use a three-stage tax delinquency process: an upset sale (liens survive, minimum bid equals all back taxes), a judicial sale (court-ordered, most liens wiped), and a repository list for anything that still does not sell.
Allegheny County skips the upset sale entirely. Tax-delinquent properties here go directly to sheriff's sale, typically initiated by a mortgage lender or another lienholder seeking to collect on a debt. This distinction matters when you start asking which liens survive the purchase.
What Is the Allegheny County Sheriff's Sale Process?
The Allegheny County Sheriff holds real estate sales monthly, on the first Monday of each month. Sales are conducted virtually via Microsoft Teams. Bidding is live and oral, not a sealed-bid system.
To participate, register on the Allegheny County Sheriff's website at least seven days before the sale date. Submit a copy of your valid state ID or driver's license and allow about two business days to receive your bidder number.
Payment rules are strict and enforced. If you win a bid on Monday, you pay 10% of the purchase price (minimum $75) in cash, certified check, or cashier's check on the day immediately following the sale, between 8:30 AM and 2:30 PM at the Sheriff's Office. The remaining balance is due by Friday of that same week.
Miss the deposit and you are permanently banned from all Allegheny County sheriff's sales. There is no appeal. The county takes this seriously, and so should you.
What Is the Pittsburgh Treasurer's Sale?
Separate from the sheriff's sale, the City of Pittsburgh runs its own Treasurer's Sale for properties with unpaid city, school district, and Allegheny County taxes within city limits. This operates under the Second Class City Treasurer's Sale and Collection Act and is a distinct process from the monthly sheriff's auction.
Properties typically need at least a couple of years of delinquency to reach a Treasurer's Sale. The prior owner or legal heir has a 90-day redemption window after the sale to reclaim the property by paying all outstanding taxes and costs. Build that holding-period risk into your numbers before you plan any renovation timeline.
Sale dates and property lists are published in the Pittsburgh Legal Journal. For current schedule and upcoming inventory, contact the Pittsburgh Treasurer's Office directly at 412-255-2300.
Which Liens Survive? The Most Important Question Investors Get Wrong
This is where most first-time tax-sale buyers get burned. It is worth spending real time on before you ever sit in on an auction.
At a mortgage foreclosure sheriff's sale, whether existing liens survive depends on who initiated the foreclosure and what position they hold. If a first mortgage holder foreclosed, junior liens (second mortgages, judgment liens) are typically wiped out. You receive essentially clear title once the sale closes and the first position is satisfied by the proceeds.
Here is the critical risk: if a junior lienholder initiated the foreclosure, the first mortgage is not extinguished. You buy the property subject to it. That first lender can foreclose on you next. This is not a theoretical risk. It happens, and it wipes out buyers who did not check.
What typically survives any sheriff's sale regardless of who foreclosed:
- Municipal liens (unpaid water, sewer, code violations, demolition orders)
- IRS federal tax liens, unless the IRS received proper notice and failed to respond within the required window
- Ground rents separately taxed or preserved by statute
What typically gets wiped out when a senior position foreclosed:
- Junior mortgages
- Judgment liens from contractors or creditors
Do a full title search before you bid. Visit the Register of Wills, Prothonotary, Recorder of Deeds, Federal Clerk of Courts, County Clerk of Courts, County Treasurer, and the local municipal tax collector. Every office. No shortcuts. The cost of the search is negligible against what you lose if you miss a first mortgage or a federal lien.

There are none. Properties at sheriff's sales sell strictly as-is. No disclosure statements, no inspection contingencies, no interior access before the auction. You can drive by and examine the exterior. That is the extent of your condition due diligence.
What you cannot know from the street:
- Whether the heating system works or has been drained for a vacant winter
- Knob-and-tube wiring, which is common in Pittsburgh's pre-1950 housing stock and expensive to remediate
- Sewer lateral condition: the city dye test required on most residential transfers does not apply to sheriff's sales
- Open permits or unpermitted work from previous owners
- Actual rehab scope beyond what is visible from the sidewalk
This is not a reason to avoid the process. It is a reason to be conservative. For Pittsburgh's old housing stock, add at least 20 to 25 percent to whatever rehab estimate you form from the outside. The surprises run in one direction.
What If Someone Is Still Living in the Property?
If the house is occupied when you win the bid, you cannot simply move in or start work. Legal process is required, and it takes time.
- Former owner still in the house: File an ejectment action, a civil lawsuit. Budget several months and attorney fees, depending on the court docket.
- Tenant in the property: Pennsylvania standard eviction process applies under landlord-tenant law. Different legal standards than ejectment, but also not fast.
Do not plan to start demo the week after closing. Build the occupancy timeline and legal costs into your holding calculation before you decide what to bid.
The Pittsburgh Land Bank: A Cleaner Alternative for City Properties
For vacant and tax-delinquent properties within Pittsburgh city limits, the Pittsburgh Land Bank is worth knowing about. It acquires blighted properties and resells them at negotiated prices to buyers who commit to rehabilitation. The process is slower and inventory is limited compared to the sheriff's sale channel, but you get a documented title chain without the auction-day uncertainty.
It is not a high-volume deal source. But if you find a specific property stuck in the city's tax delinquency system and want a cleaner path to ownership, it is an option. More at pghlandbank.org.
Due Diligence Checklist Before You Bid
Run through this on every Allegheny County tax sale or sheriff's sale property before you compete:
- Pull the full deed, mortgage, and lien history at the Recorder of Deeds.
- Check the Prothonotary for judgment liens against the current owner.
- Check the Federal Clerk of Courts for IRS and federal judgments.
- Identify who initiated the foreclosure and confirm their lien position.
- Call the local municipality for open code violations, permits, or pending demolition orders.
- Drive the property. Note exterior condition, occupancy signs, and the block around it.
- Pull comparable sales and current rental rates in the area.
- Build a conservative rehab estimate, then add 25 percent.
If your numbers still work after all of that, you have a real bid to make. If they do not, the discipline to walk is what keeps your portfolio healthy.
Where Tax Sales Fit in a Pittsburgh Investment Strategy
Sheriff's sales and treasurer's sales are not a shortcut. They reward buyers who have done the work before the auction and can move confidently on properties most buyers will not touch: deferred maintenance, title complexity, occupancy situations. The low prices exist for a reason.
When the math works, the returns can be significant. A $22,000 sheriff's sale acquisition on a McKees Rocks or Wilkinsburg double that rents for $1,400 per month is a deal structure a retail buyer with a conventional mortgage never gets access to. Whether those rental numbers actually pencil depends on the borough's tax millage and the rehab scope. For the full breakdown, see Best Pittsburgh Neighborhoods for Rental Cash Flow and the 1% rule reality in Pittsburgh.
The honest caveat: most of the highest-margin acquisitions never make it to any public auction list at all. Distressed owners often settle directly with buyers before the sheriff's sale notice goes out, sometimes for less than the total tax balance. That is the off-market channel, and it is where the real edge lives for active Pittsburgh investors.
