How tax sales, foreclosures and probate work in Delaware County, PA

Overview

Not legal advice: check with a local real-estate attorney before you buy at a tax sale or sheriff sale.

Delaware County stands out in LeadCounty for two reasons. First, the property file is unusually complete. Every parcel has an owner, a mailing address, a last sale, and nearly all have year built, living area, bedrooms, baths and a school district. A last sale price is on 96% of parcels, which is much more than most counties. Second, about 3.7% of parcels (around 7,000) carry a tax delinquent and tax lien flag. That is the Tax Claim Bureau's list, and it is a big group.

About 59% of parcels carry a homestead flag, which means the owner has claimed the home as a main residence. That makes it easy to split owner-occupants from landlords.

Please read the Pennsylvania state rules first for how the Tax Claim Bureau, the upset sale, the sheriff sale and probate work. This guide covers what is different in Delaware County.

Reading the records: what you will see and what it means

Each small section starts with what you see in LeadCounty, then what it means, the usual reasons, and what to do.

Owner name, mailing address and owner history

• Mailing address = the property: the owner lives there.
• A mailing address in another Delco town: a landlord or a family member.
• An out-of-state mailing address: an heir, a retiree who moved south, or an investor. Florida and the Carolinas are common.
• A care-of line, a bank or a law firm: an estate, a trust or a servicer.

Homestead flag

• Homestead on, long ownership: a resident owner, usually with the most equity. Slow, respectful work.
• Homestead off, mailing address elsewhere: a rental or a second home.
• Homestead on, "Estate of" in the name: the owner has died. The exemption has not been removed yet.

Tax delinquent, tax lien and tax owed

• Small (under a thousand dollars): often a forgotten bill, a wrong mailing address or a small part-payment.
• Medium (a few thousand): one or two years behind. The owner may be able to catch up with a payment plan.
• Large: several years, with interest and costs. The upset sale is near.

• Delinquent + out-of-state mailing + a house older than 1950: a landlord or heir who has stopped caring.
• Delinquent + homestead on + very long ownership: a resident in trouble. Mention the payment plan.
• Delinquent + "Estate of": a title cleanup is likely.
• Delinquent + a lien from the borough or school district: more than one creditor.

Upset, judicial and repository sale lists

Last sale price and years owned

• A price of $1 to a few thousand dollars: a family or related-party transfer. The county does not publish the deed type on sales, so a low price is a flag, not an answer.
• A series of fast resales: a flipper chain. The price steps show the spread.
• Market value is the county's number. Use it for equity, but remember it is a guide.

School district

Foreclosure and Sheriff sale list

• Sheriff sale + long ownership + a low last price: probably high equity. A quick sale could leave cash.
• Sheriff sale + recent high-price purchase: likely underwater.
• Sheriff sale + Tax Claim list: two creditors. A title company must sort the order.

Recorder of Deeds

The County Recorder's index (on Delaware County's public search) shows deeds, mortgages, releases and assignments. In LeadCounty it is a recent addition, with records from mid-2026. For older records, use the public search directly.

Likely-to-sell score

This score combines long ownership, absentee status, tax list flags, estate signs, price and homestead into one number per parcel. In Delco, with so many tax-list flags, it helps you rank. It is a guide, not a promise.

Useful combinations

• Tax Claim list + out-of-state mailing + twin or row house older than 1950: a tired landlord or an heir. The most common workable lead.
• Upset sale list + homestead on + long ownership: a resident owner near a sale. Time is short, and a payment plan may save the home.
• Estate owner + no homestead + a delinquent tax: a title cleanup, likely with several heirs.
• Repository list + Chester + blight flag: a distressed building. Walk it first.
• Sheriff sale + high equity + long ownership: the owner can leave with cash.
• Quick resales + a new LLC + no homestead: a flipper. May sell again at a retail price.
• Radnor or Haverford home + very long ownership + senior owner + no lien: equity and no pressure. Respectful, fair pricing.

Step by step: the tax timeline

Here is how one unpaid bill moves through Delaware County.

1. Early in the year. County and municipal taxes are billed, with a discount for early payment. School taxes are billed in summer.
2. After the penalty date. The tax collector adds a penalty and keeps trying. Later, the collector returns the unpaid taxes to the county.
3. The Tax Claim Bureau. The Bureau takes over, adds interest and costs, and sends notices by certified mail and posting.
4. A payment plan. Owners can often agree to monthly payments and stop the sale.
5. The upset sale. If the taxes are still unpaid after about two years, the property is on the upset sale list. The price is the taxes, interest and costs.
6. The judicial sale. If the upset sale does not sell the property, the county goes to court and sells at a judicial sale.
7. Repository. If it still does not sell, the property goes on the repository list and can sell at any price.

The owner's last chance to pay is before the sale. There is no redemption afterward. The rules are in the Pennsylvania guide, and the county explains its process on the upset sale page.

Foreclosures and auctions

Delaware County foreclosures go through the Court of Common Pleas. The lender sends an Act 91 notice, files a complaint, wins a judgment and gets a writ. The Sheriff then lists and sells the property.

• The Sheriff's lists are published as documents, by sale date, on its real estate page.
• The buyer usually pays a deposit on the day and the balance within a set period. Read the terms on the notice.
• Sales are often postponed. A date is a possibility.
• There is no redemption after the sale. The owner's last chance is before the sale.
• Many homes are occupied. Eviction is a separate court step.
• Unpaid taxes, municipal liens and some other debts can stay with the property. Use a title company.

What this means for you:

• Before the judgment: the owner has the most options. A direct sale can leave cash in hand.
• After the judgment, before the sale: you need the lender's payoff letter and a fast closing.
• At the sale: you buy as is, usually without seeing the inside.

Inherited homes and probate

Estates in Delaware County go to the Delaware County Register of Wills in Media. The Register gives the executor or administrator letters, and only that person can sign for the dead owner.

Delco has many families who bought a twin or a bungalow in the 1960s or 1970s and stayed. Their children often moved away. Some homes sit in a dead owner's name for years.

What to look for:

• "Estate of" or "Heirs of" in the owner name.
• A homestead flag that is still on after the owner's death.
• A mailing address that points to a relative or a law office.
• A tax claim flag on a house with the same owner for 40 years.

Pennsylvania's inheritance tax is 0% for a spouse, 4.5% for children and grandchildren, 12% for siblings and 15% for others. Siblings and non-relatives may sell quickly. See the state guide. Deal only with the person who holds the letters.

Who publishes what (with links)

Not published in Delaware County: deed types on sales, school and municipal tax shares per bill, permits, and a rental or vacancy registry.

How to use this as an investor or wholesaler

• Spring to summer: county and municipal bills are due or late. Owners feel the pressure.
• Summer before the upset sale: the owner's last months. A payment plan may still work.
• After the sale list is posted: weeks remain.
• After a death: wait a few weeks, then write gently.

• Say who you are and what you offer. No pressure lines.
• Tell owners about payment plans and HEMAP when they apply.
• Pay what you say, and put every promise in the contract.
• Be kind to grieving or ill owners.

Watch out for

• The tax owed is the county share only. School and municipal bills may add more.
• No redemption after a sale. The owner's last chance is before the sale.
• Free-and-clear is not total. Some claims can stay. Use a title company.
• Low prices are not sales. The deed type is not published, so $1 can mean a family transfer.
• Blight and fire. Check code orders and structure.
• Tenants. Occupied homes stay occupied after a sale.
• Sheriff dates move. Plan for postponements.
• Wrong person. Estates may have several heirs.
• Other liens. Municipal liens and judgment liens may survive. Use a title company.
