How to calculate your maximum bid, avoid overbidding, read the room, and win properties at Allegheny County sheriff auctions without overpaying.
Walk into any Allegheny County sheriff sale without a pre-calculated maximum bid and you'll almost certainly overpay. The auction environment — competing bidders, fast-paced roll call, adrenaline — is designed to push prices up. Your job is to decide your number before you step into that room.
This guide gives you a systematic approach to setting your max bid and the discipline to walk away when the room goes higher.
Maximum Allowable Offer (MAO)
MAO = ARV × 70% − Rehab Costs − Closing/Holding Costs
ARV = After Repair Value (what the property is worth fully fixed up)
Example Calculation
If the bidding exceeds $33,000 in this example — you walk away. The numbers don't change because someone else wants the property.
The county collects delinquent taxes. On Free & Clear properties, the sale wipes prior liens. This is the cream of the crop — you can bid more confidently because title risk is minimal. These are the properties to fight for.
Surviving liens (IRS tax liens, senior mortgages) may not be wiped by the sale. Always run a title search. Discount your max bid by the estimated cost of clearing any surviving liens — or avoid these entirely until you're experienced.
Water, sewer, or code violation liens. Similar to tax liens but less common. Always check for co-existing IRS or senior mortgage liens that could survive.
The opening bid is not a fair market price
The minimum bid covers the plaintiff's costs — taxes owed, attorney fees, filing costs. On a heavily delinquent property this might be $3,000–$8,000. That doesn't mean the property is worth that. Competing bidders will push it to market reality.
Watch for 'phantom bidders'
Sometimes the plaintiff (the bank or county) bids to protect their interest. If a bank bids, they're not paying cash — they're effectively buying their own note back. A third-party investor only wins if they can outbid the plaintiff.
Thin auction days are the best days
A cold February morning with few bidders is where deals get made. High-profile properties with lots of social media attention attract retail buyers who overbid. Target the boring-looking properties in working-class neighborhoods — those have less competition.
Increment bidding strategy
Start low and bid in small increments ($500–$1,000). Don't jump up in large increments — it signals desperation and invites others to push higher. Stay calm and methodical.
Even the best-researched property can become a bad deal overnight. The morning before every auction, run through this list:
The best investors in Allegheny County all say the same thing: the deals you don't make are just as important as the deals you do.
Walk away when:
There is always another auction — the first Monday of next month. Never let FOMO drive you past your number.
