How tax sales, foreclosures and probate work in Montgomery County, PA
Montgomery County, called Montco, wraps around the northwest of Philadelphia. It has about 311,000 parcels in 62 municipalities and 22 school districts, which makes it one of the biggest counties in Pennsylvania. It is also one of the most varied. Lower Merion, Cheltenham, Abington and Upper Dublin are older, well-off suburbs, with stone and brick houses, train stations and strong schools. Norristown, the county seat, and Pottstown are old mill towns with row houses, many rentals and a long history of vacant buildings. Lansdale, Souderton, Hatboro and Ambler are historic boroughs with walkable centers. Upper Merion, Conshohocken and Plymouth Meeting are mixed office, apartment and shopping districts around King of Prussia. The north and west (Hatfield, Telford, Green Lane, Boyertown) are more rural, with farms and new developments.
Overview
Not legal advice: check with a local real-estate attorney before you buy at a tax sale or sheriff sale.
The most important fact for a data buyer is this: Montgomery County has no single tax collector. School, township or borough, and county taxes are collected by local tax collectors, one per municipality, so there is no county-wide file of who owes what. What the county does publish is the Tax Claim Bureau's records, which is the list of taxes that went unpaid long enough to be turned over. The Bureau's search page shows one parcel at a time. We have read part of it, so some parcels have a delinquent flag and many do not. A missing flag does not tell you the owner is current.
In LeadCounty about 2.3% of parcels (around 7,200) carry a tax delinquent and lien flag. The property file is otherwise very complete: owner, mailing address, building facts, bedrooms, baths and a last sale price on 91% of parcels.
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 Montgomery 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, care-of and mailing address
An owner name, sometimes a care-of line, and a mailing address on every parcel.
The Board of Assessment Appeals publishes a weekly parcel file with the owner, the care-of line, the mailing address and the property address. The care-of line is useful. It often holds the name of a person who manages the property, or an heir, or a trustee.
- Mailing address = the property: the owner lives there.
- A different Montco address: a landlord or a family member.
- A mailing address in another state: an heir, a retiree or an investor.
- A "c/o" with a law firm or a trust company: an estate or a trust.
Look at the care-of line before you write. The right name may be there.
Owner type and land use
Person, LLC, trust or company, and a land use class.
In Norristown and Pottstown, LLCs are mostly landlords with several row houses. In Lower Merion and Abington, LLCs often belong to builders who buy old houses to rebuild. The county's own parcel codes guide explains each land use, building style, wall type, basement and sale reason, so we use the county's meaning, not a guess.
Sort by land use first. A single-family house, a twin, a row house, a condo and an apartment building are very different deals.
Years owned, last sale and the sale reason
A last transfer date on 99% of parcels and a last sale price on 91%, but a deed type on only 4%.
Montgomery gives a price and a county sale reason code, but the deed type is mostly not published. The monthly assessment change file adds the previous owner and old and new values for recent transfers, and gives a reason. So you can tell a normal sale from a family transfer or a sale between related companies.
- A normal sale code and a price near value: use it to estimate equity.
- A tiny price with a non-sale code: a family transfer. Ignore the price.
- A sale to an LLC at a low price: an owner moving the house into a company.
- A sale in the last two years at a very high price: little equity.
Montgomery's assessments are old, since the county has not reassessed everything in decades. The assessed value is not market value. Use the market value in LeadCounty for equity.
Tax delinquent and tax lien: the Tax Claim Bureau
A delinquent flag and a "delinquent since" year on about 7,200 parcels.
The Bureau's delinquent tax search shows unpaid taxes by year, with penalty and interest, and its yearly upset sale and judicial sale lists show results. These taxes were already returned by the local collector, so they are at least a year old. The search reads one parcel at a time. We have read part of the county, and the flag applies where we have read it. For the rest, the flag is blank, not "paid."
- Landlords of row houses in Norristown and Pottstown.
- Heirs of older owners who have not opened an estate.
- Owners of vacant lots and odd parcels.
- Retirees in older homes with rising tax bills.
- Small commercial owners, such as a closed shop.
- Delinquent + out-of-state mailing + older building: a landlord or heir who has stopped caring.
- Delinquent + resident owner + decades of ownership: a long-time resident in trouble. Mention the payment plan.
- Delinquent on a Lower Merion or Abington home: rare. More often a death, a divorce or a medical problem.
- Delinquent + "Estate of": a title cleanup is likely.
Check the Tax Claim Bureau search for the one property. Then check the school district and municipality for their shares.
The Board's tax estimate
A yearly tax figure on every parcel.
The Board of Assessment Appeals gives its own tax estimate for the county, municipal, school and community college shares. It is a computed figure from the rates, not a bill. The real bill comes from your local collector. The figure is useful for comparing homes, but a real bill may differ if the owner has a homestead or other change.
Bedrooms, baths, living area and year built
Year built, living area, bedrooms and baths on about 87% of parcels.
The county file also holds stories, style and condition. You can size up a house before you call. A Norristown row house with 3 bedrooms and 1 bath is a different project from a Lower Merion stone colonial with 5 bedrooms. Much of Montco was built between 1920 and 1970, so wiring, plumbing and heating are common questions.
Use bedrooms and baths to guess rent and resale. Use year built to guess repairs.
Sheriff sale list
Sheriff sale entries, with dates and status.
The Montgomery County Sheriff publishes sale-day reports and lists (the Law Reporter). A property on the list has a lender judgment and is headed for a sale. The auction runs on the Bid4Assets site, which blocks our collectors, so we read the Sheriff's own lists instead. You can see current sales on the Sheriff's auction page.
Job loss, divorce, an adjustable loan that reset, a reverse mortgage after a death, and landlords who stopped paying a lender.
- 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 flag: two creditors. A title company must sort the order.
Abington and Norristown vacant property registers
Vacant-property markers, service requests and planning reviews in two municipalities.
Abington Township and Norristown publish their own registries. A registered vacant building is one the municipality knows to be empty, and the owner has a duty to keep it up and pay fees. This is a direct signal of an owner who may be ready to let go. Service requests show neighbor complaints.
For these two places, start with the registry. Then check the owner and the tax record.
Monthly assessment changes
Recent transfers with the previous owner, old and new values, a deed book and page, and a reason.
The county's monthly change file shows who sold to whom lately. It gives the seller's name for about 3,000 recent changes. You can see a fast flip or a transfer to a trust within weeks of its recording.
Likely-to-sell score
This score combines long ownership, absentee status, tax flags, estate signs, price and vacancy into one number per parcel. In Montco, it helps you rank a very large file. It is a guide, not a promise.
Useful combinations
- Delinquent + Norristown or Pottstown row house + out-of-state mailing: a tired landlord. The most common workable lead.
- Vacant registry + delinquent + absentee owner: a building the owner may be ready to let go.
- Estate owner + care-of to a law firm + older house: an estate selling. Usually cooperative.
- 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.
- Lower Merion or Abington home + very long ownership + senior owner + no flag: equity and no pressure. Respectful, fair pricing.
- Delinquent + a Pennsylvania school district with a high tax rate + modest value: the debt may be close to what the home is worth.
Step by step: the tax timeline
Here is how one unpaid bill moves through Montgomery County.
- Early in the year. County and municipal bills go out with an early-pay discount. School bills go out in summer.
- After the penalty date. The local tax collector adds a penalty and keeps trying.
- Return to the Tax Claim Bureau. The collector gives the county the unpaid taxes.
- Notices. The Bureau sends certified mail and posts the property. Owners can ask for a payment plan.
- The upset sale. After about two years of unpaid tax, the property goes on the upset sale list. The price is the taxes, interest and costs. The county explains this on its upset sale page.
- The judicial sale. If it does not sell, the county goes to court and sells at a judicial sale.
- Repository. If it still does not sell, it can be sold 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.
Foreclosures and auctions
Montgomery 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 sells the property.
- Sales run through an online auction with a registration step.
- The buyer pays a deposit soon after the sale 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.
A Tax Claim Bureau sale clears most liens, but not all. A Sheriff sale of a first mortgage may leave a tax lien alive. The two sales are run by different offices.
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 Montgomery County go to the Montgomery County Register of Wills in Norristown. The Register gives the executor or administrator letters, and only that person can sign for the dead owner.
Montco has a lot of older housing owned by the same family for decades, especially in the older boroughs. Many children 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 care-of line with a law firm.
- A monthly change file entry showing a recent transfer from an estate.
- 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.

How to use this as an investor or wholesaler
With a partial tax list, stack signals: vacancy, estate, absentee, years owned.
- Spring to summer: 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 Sheriff 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.
Pennsylvania now regulates residential wholesaling (Act 52 of 2024): a real estate license, clear written notice to the seller in the contract, and a seller right to cancel for 30 days. Sign your own contract and do not advertise a home you do not control. See the state guide.
In the wealthy suburbs a lot can be worth more than the house. Know what a builder pays, and be honest with the owner about the lot value.
Watch out for
- The tax flag is partial. We have read part of the Bureau's records. A blank is not paid.
- Many collectors. School and municipal bills are separate. Check each.
- Old assessments. Use market value, not assessed value.
- 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.
- Tenants. Occupied homes stay occupied after a sale.
- Vacant fees. Registered vacant buildings can carry fees and fines.
- 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.
