Delaware to Chester County PA: The Honest Financial Picture for 2026

Delaware to Chester County PA: The Honest Financial Picture for 2026

Every year I talk to buyers making the move from Delaware to Chester County PA, and the conversation almost always opens the same way. They have done some reading, they have seen that Pennsylvania has a flat 3.07 percent income tax against Delaware’s rate that climbs toward 6.6 percent, and they want to know how much they are going to save.

I have to tell them the truth, which is that they are probably not going to save anything. In most cases they are going to pay more.

That is not the answer people expect from a mortgage broker who would benefit from them buying a house up here. But it is the honest one, and going into a $600,000 purchase with the wrong assumption about your annual carrying costs is a bad way to start.

I am J.R. Conway, owner and VP of CM Mortgage Services Inc., a second generation, family owned mortgage brokerage at 1240 West Chester Pike in West Chester. I have been financing homes across Chester County for over 20 years and southern Chester County sits close enough to the Delaware line that I work with these buyers regularly. This post covers the real tax picture, the one detail almost nobody explains correctly, what you actually get in exchange for the higher costs, and what the mortgage math looks like when you cross the state line.

Where Delaware Genuinely Beats Pennsylvania

Let me start here, because pretending otherwise would be dishonest.

Delaware has no sales tax. Not a low one. None. Pennsylvania charges 6 percent. On a year of ordinary household spending, appliances, furniture, a car, that difference is real money, and it is money you stop keeping the day you change your address.

Delaware’s property taxes are among the lowest in the Northeast, with an effective rate running around 0.54 to 0.57 percent of home value. A $400,000 home in New Castle County averages somewhere near $2,280 a year in property tax.

Chester County is the other end of that spectrum. The Philadelphia suburbs, including Chester, Montgomery, Delaware, and Bucks Counties, carry effective property tax rates that typically run 1.5 to 2 percent of market value. Chester County’s median property tax bill is the highest in Pennsylvania.

Run that on a real purchase. A $600,000 Chester County home can carry $9,000 to $12,000 a year in property taxes depending on the township and school district. That is $750 to $1,000 a month, compared to roughly $190 a month on that $400,000 Delaware home.

That difference does not show up in a listing price. It shows up in your monthly payment, every month, for as long as you own the house. It is the single biggest financial adjustment a Delaware buyer makes coming into this county, and it is the reason I will not quote a Chester County payment off a county average. I pull the actual millage for the specific parcel.

The Income Tax Detail That Almost Nobody Explains

Here is where the conventional wisdom breaks down, and it is worth reading carefully.

Pennsylvania and Delaware do not have a tax reciprocity agreement. Pennsylvania has reciprocal agreements with Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia. Delaware is not on that list. Neither is New York.

What that means practically: if you move to Chester County but keep your job in Wilmington or anywhere else in Delaware, you are still going to file a Delaware nonresident return and pay Delaware tax on that Delaware sourced income. Pennsylvania will give you a credit for what you paid Delaware, but that credit is capped at the lesser of what Delaware charged or what Pennsylvania would have charged on the same income.

Because Delaware’s rates run higher than Pennsylvania’s flat 3.07 percent, the credit gets capped at the Pennsylvania figure. The practical result is that you end up paying at roughly Delaware’s rate on that income anyway. The Pennsylvania income tax advantage you were counting on does not materialize.

On top of that, Wilmington charges a 1.25 percent wage tax that applies to nonresidents who work in the city, not just residents. Moving across the state line does not get you out of it if your job stays put.

You will also owe a Pennsylvania local earned income tax, which in most Chester County municipalities runs somewhere in the 1 to 1.5 percent range.

The income tax advantage is real, but only for income that is actually sourced in Pennsylvania. If you are fully remote for a Pennsylvania employer, or you change jobs to this side of the line, the flat 3.07 percent works in your favor. If you are commuting back into Delaware every day, plan on the Delaware number.

I want to be clear that I am a mortgage broker, not a tax advisor, and multistate returns get complicated fast depending on your specific employer, your work location, and how your income is structured. Before you make a decision based on any of this, sit down with a CPA who handles Pennsylvania and Delaware returns. What I can tell you with confidence is that assuming an automatic income tax savings is the most common mistake I see Delaware buyers make when they build their budget.

So Why Do People Keep Making This Move?

If the tax picture is worse, and the houses cost more, the obvious question is why anyone does it. The answer is that nobody moves from Delaware to Chester County to save money on taxes. They move for the things taxes pay for and the things money cannot buy back.

The school districts. Chester County’s property taxes are high specifically because the school districts are funded well. Downingtown Area, West Chester Area, Unionville Chadds Ford, Great Valley, and Avon Grove consistently rank among the strongest public districts in Pennsylvania. For a family with school age children, that is the entire argument, and it is why so many buyers accept the higher carrying cost without hesitation.

The land and the housing stock. Southern and western Chester County offers something that is genuinely hard to find in northern New Castle County: acreage, preserved open space, historic stone farmhouses, horse country. Chester Springs, West Grove, and the areas around Unionville and Chadds Ford give you a kind of property that simply is not available in most of Delaware at any price.

The towns. Kennett Square has a walkable downtown, a nationally recognized food scene, and the highest percentage population growth of any Chester County borough between 2020 and 2026. West Chester Borough has the dining and the historic architecture. Phoenixville has Bridge Street. These are places with an identity, not just subdivisions with a zip code.

And then there is I-95.

The I-95 Factor

If you live in northern Delaware, you do not need me to explain this. But it belongs in the honest accounting of why people move, because it comes up in nearly every one of these conversations.

The I-95 corridor through Delaware has been under near continuous construction. The Route 896 interchange in Newark has been a reconstruction project running from 2023 into 2026, with lane restrictions throughout and the final ramp connections opening this spring. The stretch of I-95 northbound between Route 141 and the I-495 split has had bridge redecking work with a lane blocked around the clock into spring of 2026. DelDOT activated an electronic speed enforcement program in the Route 896 construction zone in May, and there is ongoing lane closure work for concrete demolition on the southbound side.

That is on top of the baseline reality that I-95 through Wilmington is one of the busiest stretches of interstate on the East Coast, and it is the default route for an enormous amount of through traffic between Baltimore, Philadelphia, and New York.

Here is what makes Chester County interesting for a Delaware buyer specifically. The routes north into southern Chester County do not use I-95 at all. Route 52 runs from Wilmington up through Greenville and into the Kennett Square area. Route 202 runs north toward West Chester. Route 41 and Route 1 both feed into the southern county. These are surface roads through Brandywine Valley countryside, and for a lot of buyers the commute genuinely improves even as the distance increases.

Kennett Square sits roughly 12 miles from Wilmington. Chadds Ford and Glen Mills are effectively on the border. For someone whose job stays in northern Delaware, that is a very manageable daily drive that never touches the interstate.

Which Chester County Communities Work for Delaware Buyers

Not every part of the county makes sense if your work or your family ties keep you connected to Delaware. These are the ones that do.

Kennett Square is the most natural landing spot. Twelve miles from Wilmington, a genuine downtown, and the strongest appreciation story in southern Chester County. The average home value runs around $569,000 with homes going pending in roughly six days, so it is not a bargain market anymore, but the community is the draw. See our Buying a Home in Kennett Square PA guide and our Kennett Square mortgage page.

Avondale sits just south of Kennett Square and has been drawing Delaware commuters specifically. Route 1 access, newer residential development, and price points meaningfully below Kennett Square. If Kennett Square is the goal but the numbers do not work, this is where to look. Visit our Avondale mortgage page.

West Grove offers the most land per dollar in the county and sits within the Avon Grove School District. For buyers coming from a Delaware townhouse or a smaller lot, this is where the trade starts to feel worth it. See our West Grove mortgage page.

Chadds Ford sits right on the border and carries the Brandywine Valley premium. Larger properties, significant acreage, and Unionville Chadds Ford School District access. This is the higher end of the Delaware relocation market and it frequently pushes into jumbo territory. Visit our Chadds Ford mortgage page.

Glen Mills straddles the Chester and Delaware County line and attracts buyers relocating from northern Delaware who want newer construction and easy Route 202 access. See our Glen Mills mortgage page.

West Chester Borough is the move for buyers who want walkability and are not commuting to Delaware daily. Average sale prices above $700,000 make it the most expensive option on this list. Visit our West Chester mortgage page.

What the Purchase Actually Looks Like

The price gap is the other adjustment Delaware buyers make.

New Castle County’s median sold price was running around $381,000 in early 2026, up 8.5 percent year over year, with homes averaging 40 to 49 days on market. Chester County’s median sits closer to $556,000 with an average home value around $576,000, and homes in the most active communities go pending in five to thirteen days.

So a Delaware buyer is typically trading up in price and trading down in decision time. That combination is why preparation matters more here than it did on the other side of the line. A buyer who is used to having a couple of weeks to think about a house is going to lose the first three they like.

On the financing side, most Chester County transactions for this buyer profile fall within the 2026 conforming loan limit of $832,750, which means conventional financing covers it and positions your offer most competitively. Buyers targeting Chadds Ford or the upper end of West Chester can cross into jumbo territory, which carries higher credit and reserve requirements. Eligible veterans should look hard at VA financing, which eliminates the down payment and the monthly mortgage insurance entirely.

Closing costs in Chester County run 4.5 to 5 percent of the purchase price, which on a $600,000 purchase is $27,000 to $30,000 on top of your down payment. Pennsylvania charges a 1 percent state realty transfer tax and Chester County municipalities typically add another 1 percent, with that combined 2 percent split between buyer and seller by custom.

The Number You Need Before You Write an Offer

Everything in this post comes back to one thing. Your monthly payment in Chester County is going to be driven by a property tax bill that is several times what you are used to, and it varies enormously by township and school district within this county.

Two homes at the same list price a few miles apart can carry monthly payments that differ by hundreds of dollars. A generic estimate built off a county average will not tell you what you actually need to know, and finding out at the closing table is the wrong time.

Before you write an offer on anything up here, you should know the actual annual tax bill for that specific parcel, the school district it sits in, and what the all in monthly payment looks like with taxes and insurance included. That is a short conversation and it is the one I have with every buyer coming from Delaware.

Frequently Asked Questions: Delaware to Chester County PA

Will I save money on taxes moving from Delaware to Chester County PA?
For most buyers, no. Delaware has no sales tax and an effective property tax rate around 0.54 percent. Chester County’s effective property tax rate typically runs 1.5 to 2 percent and the county carries the highest median property tax bill in Pennsylvania. Pennsylvania’s flat 3.07 percent income tax is lower than Delaware’s top rate, but that advantage only applies to Pennsylvania sourced income. Consult a CPA familiar with both states before budgeting around any assumed savings.

Do Pennsylvania and Delaware have a tax reciprocity agreement?
No. Pennsylvania has reciprocity with Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia. Delaware is not included. A Pennsylvania resident working in Delaware files a Delaware nonresident return and pays Delaware tax on Delaware sourced income, then claims a resident credit on the Pennsylvania return limited to the lesser of the two amounts. If you keep a Delaware job after moving, you should not expect Pennsylvania’s lower income tax rate to apply to that income.

How much higher are property taxes in Chester County than in Delaware?
Substantially higher. A $400,000 home in New Castle County averages roughly $2,280 a year in property tax. A $600,000 Chester County home can run $9,000 to $12,000 a year depending on the township and school district. That difference translates to several hundred dollars a month in your mortgage payment and is the single largest financial adjustment for a Delaware buyer.

How far is Kennett Square from Wilmington Delaware?
Roughly 12 miles. Route 52 and Route 1 both connect the Wilmington area to Kennett Square without using I-95. For buyers whose employment stays in northern Delaware, that commute is manageable daily and avoids the interstate construction and congestion entirely.

Which Chester County communities are best for buyers coming from Delaware?
Kennett Square, Avondale, and West Grove are the most common landing spots for buyers who need Delaware access, with Chadds Ford and Glen Mills serving the higher end of the market. All sit in southern or southeastern Chester County with direct surface road connections to northern Delaware that bypass I-95.

What loan programs work for Delaware buyers moving to Chester County?
Conventional financing covers most transactions within the 2026 conforming loan limit of $832,750 and positions offers most competitively in Chester County’s fast markets. Jumbo financing applies above that threshold, which comes up in Chadds Ford and the upper end of West Chester. VA is the strongest option for eligible veterans. The right program depends on your credit, down payment, and target price point.
