Off-market properties in Delaware County, Pennsylvania
Off-market properties in Delaware County, Pennsylvania, give investors, agents and buyers a look at homes before they reach public sites. They include private sales, unlisted homes, FSBO deals and distressed properties, from Chester and Upper Darby rowhomes to single homes in Springfield, Havertown and Newtown Square. The county rewards careful research more than speed.
What counts as off-market in Delaware County
An off-market home is one the owner would sell, but that is not listed on the MLS or advertised to the public.
No single method finds all of them. The strongest approach combines relationships, direct outreach, street-level observation and reliable data, then compares seller motivation, condition, location and likely resale value.
Delaware County’s housing ranges from dense rowhome blocks on the Philadelphia line to large-lot suburbs in the west, so the right method changes from one ZIP code to the next.
- Listed on the MLS
- Advertised to the public
- Every shopper can see it
- Not listed on the MLS
- Not publicly advertised
- Found by buyers who look beyond the portals

Six ways to reach Delaware County sellers first
Each source catches a different kind of seller. Use several together.
Agent and pro networks
Agents, wholesalers, attorneys, contractors and property managers often hear about sales early. Respect agency relationships and disclosure rules.
Top lead types →
Direct-to-seller outreach
Mail, calls and email work when you say who you are, why you are reaching out and that there is no obligation to sell.
Skip tracing →
Probate and inheritance
Estates and heirs may sell eventually. Verify the data and never pressure a family in a hard time.
Inheritance leads →
FSBO and private sales
For-sale-by-owner homes get less exposure. Some circulate only through signs, community groups or referrals.
Off-market homes →
Driving for dollars
Look for vacancy, deferred maintenance, code issues and overgrown lots, which vary block to block in the older boroughs. Log each address, ZIP, condition and follow-up.
Absentee owners →
Foreclosure and data lists
Foreclosure lists and county records flag owners under pressure. The process is legally sensitive and time-bound, so treat any list as a starting point.

Is the deal worth pursuing? Start with after-repair value
After-repair value (ARV) is what the home should sell for once realistic repairs are done. Your margin is the gap between that value and your full cost: purchase price, repairs, holding, closing, financing, resale costs and profit.
Use recent sold comparables, not asking prices. The best comps are close by and similar in size, style, condition, school district, bedrooms and lot. In 19063 or 19064, a few blocks can change what buyers expect, so countywide averages are too blunt.
Say a home has a projected ARV of $300,000. Subtract repairs, transaction costs, holding and financing costs and your profit before you set a maximum offer. That cushion protects you from delays, missed repairs and market shifts. Beginners should be extra conservative.
Phillip Warrick explains his approach in this video, and there is a short clip on evaluating deals.
ARV checklist
- Pick three to six sold comps from the same neighborhood.
- Adjust for square footage, parking, finished basements, additions and finish quality.
- Get repair numbers from a contractor, not from optimism.
- Add acquisition, financing, insurance, taxes, utilities, permits, closing and resale costs.
- Compare total cost with ARV and decide if the spread justifies the risk.
Legal and ethical ground rules in Pennsylvania
Off-market deals must follow Pennsylvania law, federal consumer protection rules, fair housing law, licensing standards and contract disclosure requirements. Talk to a qualified attorney or agent when unsure, especially with estates, foreclosures, distressed sellers or assignment contracts.
Ethics protect both sides. Avoid misleading claims, false urgency, harassment and promises you cannot keep. Use written agreements, clear pricing, proper disclosures and give sellers time to review.
The most effective plan pairs local knowledge with steady lead generation. Whether you are reviewing 19026, 19023, 19083 or another ZIP, careful research separates a good lead from an expensive mistake.

19082 · Upper Darby (north): off-market investor snapshot
The county’s most populous ZIP, centered on 69th Street and the township’s dense rowhome blocks.
Local search demand
Resale demand: About 30 searches a month: buyers exist, though rental investors usually move faster here.
Investor note: More than 41,000 people live here, but only 49% of homes are owner-occupied and the median value is $169,900. Vacancy is 7.8%. This is landlord country, so absentee-owner and tired-landlord leads should come first.
19026 · Drexel Hill: off-market investor snapshot
Twins, rowhomes and single homes in Upper Darby Township’s southern half.
Local search demand
Resale demand: About 130 searches a month put it among the county’s busiest ZIPs, a good sign for a renovated resale.
Investor note: At $271,100 the median value is about 18% below the county, with 65% owner-occupancy and 5.0% vacancy. Only 69% of homes are single-unit structures, so twins and rowhomes dominate. Long-time owners and estates create steady inherited-home opportunities.
19023 · Darby / Colwyn: off-market investor snapshot
A dense borough of rowhomes on the Philadelphia border along Cobbs Creek.
Local search demand
Resale demand: About 40 searches a month: modest retail demand, so a rental or investor exit is often more reliable.
Investor note: The median value is $153,300, less than half the county’s $332,200, and only 53% of homes are owner-occupied. Vacancy is 8.8%. Older rowhomes with deferred maintenance make this a fit for rental buyers and light flips, but price repairs carefully.
19050 · Lansdowne / Yeadon: off-market investor snapshot
Lansdowne and Yeadon boroughs, with Victorian twins and older single homes near the city line.
Local search demand
Resale demand: About 140 searches a month, the second-highest in the county, show strong buyer interest.
Investor note: The median value is $201,900, owner-occupancy 59% and vacancy 4.6%. Only 64% of homes are single-unit, the lowest on this page, which points to conversions and small multifamily. Look for tired landlords and estates with older systems.
19083 · Havertown: off-market investor snapshot
Haverford Township’s main residential area, with single homes and twins on quiet streets.
Local search demand
Resale demand: About 130 searches a month, much of it for houses, signal strong demand from move-up buyers.
Investor note: Vacancy is just 1.9%, the lowest on this page, and 88% of homes are owner-occupied. The $452,100 median value is about 36% above the county. Very few homes sit empty, so inherited and aging-owner leads are the most realistic path.
19063 · Media and Middletown: off-market investor snapshot
The county seat of Media and the surrounding Middletown and Upper Providence townships.
Local search demand
Resale demand: Around 80 searches a month show solid buyer interest in this higher-priced market.
Investor note: The median value is $548,900, about 65% above the county, and income reaches $127,368. Owner-occupancy is 70% and vacancy 4.2%. Court filings are handled in Media, and higher-value estates mean ARV discipline matters more than raw discount.
19064 · Springfield: off-market investor snapshot
A suburban township of mostly single homes between Media and Upper Darby.
Local search demand
Resale demand: With about 360 searches a month, this ZIP has the strongest buyer demand in the county.
Investor note: Springfield has 94% owner-occupancy and 95% single-unit homes, the highest rates on this page, with just 2.6% vacancy. The $414,500 median value is about 25% above the county. Sellers are mainly downsizers and estates; expect neat homes and owners who value a smooth closing.
19081 · Swarthmore: off-market investor snapshot
A college borough with walkable streets and established single homes.
Local search demand
Resale demand: About 40 searches a month: limited but steady demand for a small, sought-after area.
Investor note: The median value is $378,600 and owner-occupancy is 80%, with 4.1% vacancy. Small block-to-block differences shift value, so pull comps from the same streets. Estates and relocations are the usual triggers.
19073 · Newtown Square: off-market investor snapshot
Newtown Township and parts of Edgmont and Marple, with larger lots near the Chester County line.
Local search demand
Resale demand: About 60 searches a month: a smaller pool of buyers for higher-priced homes.
Investor note: Newtown Square has the highest median value on this page at $610,300. Owner-occupancy is 79% and vacancy 3.7%. Deals are fewer but larger; estates and downsizing owners are the main sources, and accurate ARV is critical.
19013 · Chester: off-market investor snapshot
The city of Chester on the Delaware River, the county’s oldest community.
Local search demand
Resale demand: Only about 20 searches a month: plan on investor buyers rather than retail resale.
Investor note: Chester has the county’s lowest median value at $83,700, just 39% owner-occupancy and 16.4% vacancy. Distress is visible, so driving for dollars and foreclosure lists produce leads, but title and code issues are common. Check every file carefully.
19015 · Brookhaven / Upland: off-market investor snapshot
Brookhaven, Upland and nearby parts of Chester Township, just north of Chester.
Local search demand
Resale demand: About 40 searches a month: modest demand, best served by well-priced starter homes.
Investor note: At $246,700 the median value is about 26% below the county, with 75% owner-occupancy and 4.5% vacancy. It is more stable than Chester but still priced for entry-level buyers. Starter-home flips and rentals both work.
19014 · Aston: off-market investor snapshot
Aston Township and part of Upper Chichester, a suburban area of single homes in western Delaware County.
Local search demand
Resale demand: About 40 searches a month suggest steady, mid-market buyer interest.
Investor note: The median value of $329,800 is right at the county figure, owner-occupancy is 88% and vacancy 3.2%. Single-unit homes make up 89% of the stock. This is a balanced market for owner-occupant flips priced near the county median.
U.S. Census Bureau, American Community Survey 2020–2024 5-year estimates. Figures cover the whole ZIP code, which can cross county lines. Home values are medians for owner-occupied homes, not current list prices.
Average monthly U.S. Google searches as of October 2026. Home searches combine “homes for sale”, “houses for sale” and “real estate” for each ZIP code. Seller searches combine “sell my house fast”, “we buy houses” and “cash home buyers” for the nearest city.

Delaware County, PA off-market FAQ
Quick answers for investors working the county.
Have another question? Tell us your target ZIP codes and we will help you choose the right leads.
Which ZIP codes have the most renters?
Chester (19013) and north Upper Darby (19082) have the lowest owner-occupancy on this page, at 39% and 49%. Absentee-owner lists are the natural place to start there.
Are high-value areas like Media and Newtown Square worth targeting?
Yes Yes, but expect fewer, larger deals. Estates and downsizers drive most sales, and an accurate ARV matters more than a deep discount.
Should I treat these ZIP codes as automatic buy zones?
No No. They help you organize research. Every lead still needs its own comps, repair estimate and title check.
Can I contact heirs as soon as a death is recorded?
You can reach out, but be patient and respectful. Families need time, and pressure tactics damage your reputation and may break the law.
Do I need a lawyer for an off-market purchase?
Not always, but it is wise for estates, foreclosures and assignment contracts. Pennsylvania disclosure rules still apply.
