What Does It Actually Cost to Sell a House Here? (PA vs. NJ vs. DE)
Oct 30, 2026 · @William Holder
Selling a house around here usually costs a seller somewhere between 6% and 9% of the sale price, once you add up the commission, transfer taxes, and closing fees. But the biggest swing isn't the commission — it's which state you're selling in.
On the same $400,000 home, the transfer tax alone costs a seller roughly $4,000 in Delaware County, Pennsylvania, and about $8,000 just across the line in Delaware. Here's the real breakdown for all three markets we work.
The big picture: what a seller actually pays
When people ask what it costs to sell, they usually think about the commission and stop there. The commission is the biggest single line, but it's only part of the bill. Here are the buckets every seller should plan for:
Agent commission — the largest cost, and negotiable
Transfer tax — the wild card, because it changes a lot by state and town
Settlement and closing fees — title/settlement charges, deed prep, recording; an attorney in New Jersey and Delaware
Everything else — prorated property taxes, your mortgage payoff, any repairs or prep, and any concessions you give the buyer
Add it all up and most sellers land somewhere between 6% and 9% of the sale price. Where you fall in that range depends heavily on which state the house is in — which is exactly where the next section comes in.
The one that changes everything: transfer tax by state
This is where selling in Pennsylvania, New Jersey, and Delaware stop looking alike. Same price, very different bill — and the rules for who pays differ too.
Put a $400,000 sale through each one and the seller's transfer-tax cost looks like this:
Delaware County, PA: about $4,000 (your ~1% half of the 2% total)
South Jersey, NJ: roughly 3,000–4,000, and you pay all of it
New Castle County, DE: about $8,000 (your 2% half of the 4% total)
Same house, and Delaware costs the seller roughly double what Pennsylvania does. A couple of important wrinkles: in New Jersey, homes over $1 million now trigger an extra graduated fee that — since mid-2025 — the seller pays; and in Delaware, first-time buyers can be exempt from the county portion, which can come up in negotiation.
Commissions and the rest of the costs
Commission is still the biggest line. Since the industry changes that took effect in 2024, commission is clearly negotiable and the buyer's-agent portion is now negotiated deal by deal rather than preset. Total commission commonly lands in the 5%–6% range, but it's a conversation, not a fixed number — and what you get for it matters as much as the rate.
Settlement costs cover the title/settlement work, deed preparation, and recording. In Pennsylvania this usually runs through a title company (no attorney required) — which, full disclosure, is a business I'm in through Classic Settlements. In New Jersey and Delaware, an attorney typically handles the closing, adding roughly 1,000–2,500.
One New Jersey-specific item: if you're selling a New Jersey home and moving out of state, the state withholds an estimated tax at closing — the so-called "exit tax." It's not an extra tax, just a prepayment you reconcile on your return, but it reduces the cash you walk away with, so plan for it.
How to keep more of your money
A few of these costs are fixed, but several are not:
Negotiate the commission and what it buys. Rate matters, but so does the marketing, pricing strategy, and negotiation you're getting for it. Cheapest isn't the same as nets-you-the-most.
Negotiate the transfer-tax split. In Pennsylvania and Delaware the split is customary, not mandatory. In a market where you have leverage, who pays what is fair game.
Know the exemptions. Delaware's first-time-buyer exemption on the county portion can be a real bargaining chip in a deal. Certain transfers are exempt in all three states.
Price it right the first time. The most expensive mistake isn't a line item — it's an overpriced listing that sits, forces price cuts, and costs you carrying expenses. Accurate pricing out of the gate protects your bottom line more than shaving a fee.
Spend prep dollars where they pay back. Targeted cleanup and small fixes return more than big pre-sale renovations.
Frequently asked questions
How much does it cost to sell a house in Delaware County, PA? Plan on roughly 6.5% to 8% of the sale price all in — commission (5%–6%, negotiable), your ~1% half of the transfer tax, plus title, payoff, and prorations. On a $400,000 home that's about 26,000–32,000.
Why is Delaware's transfer tax so much higher? Delaware's combined rate reaches 4% in New Castle County, one of the highest in the country, and it's split 50/50 — so the seller's 2% share is roughly double a Delaware County, PA seller's. It's the single biggest cost difference between the two states.
Who pays the transfer tax in New Jersey? The seller does. New Jersey's Realty Transfer Fee is paid entirely by the seller, and since mid-2025 the extra graduated fee on homes over $1 million falls on the seller too.
Are real estate commissions still 6%? Not automatically. Since the 2024 industry changes, commission is openly negotiable and the buyer's-agent portion is negotiated per deal. Many sales still land in the 5%–6% range, but it's a conversation.
Can I negotiate who pays the transfer tax? In Pennsylvania and Delaware, yes — the 50/50 split is customary, not required, so it can shift with market leverage. In New Jersey it's statutorily the seller's, though the contract can address it.
