Selling a home in Middlesex or Somerset County involves several distinct cost categories: the New Jersey Realty Transfer Fee (a statutory obligation imposed on the seller), a negotiated brokerage commission, real estate attorney fees, title and settlement charges, municipal inspection fees, and any seller credits you agree to at the negotiating table. The RTF is set by state law; everything else is negotiable. Your exact out-of-pocket picture depends on your sale price, your municipality, and the terms you agree to with your buyer — which is exactly why I walk every seller through a personalized analysis before we list.

The cost categories every Central NJ seller needs to understand

The New Jersey Realty Transfer Fee

This is the one cost that isn't negotiable away. According to the New Jersey Division of Taxation, the Realty Transfer Fee (RTF) is imposed on the grantor (seller) at the time the deed is recorded, and it's calculated on a tiered bracket schedule based on the consideration — the sale price — stated in the deed.

A few things sellers in Middlesex and Somerset counties need to know about the RTF:

• The fee scales with your sale price. The statutory schedule has multiple brackets, and as the price climbs, the per-dollar rate at each tier changes. Most homes in towns like Edison, Piscataway, East Brunswick, and Bridgewater fall into mid- and upper-tier brackets — a local attorney or title company will calculate your exact figure from the contract price.
• There's an additional fee for sales over $1,000,000. The Division of Taxation notes a separate "mansion tax" component that applies to higher-value transactions — relevant in parts of Somerset County like Basking Ridge, Bernardsville, and Montgomery where prices routinely cross that threshold.
• Reduced fees exist for qualifying sellers. Senior citizens, blind or disabled persons, and low-and-moderate-income housing transactions qualify for reduced RTF rates under state law.
• It's a seller obligation by statute — but credits are sometimes negotiated. While the RTF is legally imposed on the seller, parties occasionally negotiate cost-sharing credits. That said, the closing agent remits it when the deed records, so confirm how it's handled in your specific contract.

The RTF is also entirely separate from any federal or state capital gains tax you may owe on your profit. The IRS Publication 523 covers federal capital gains exclusions for primary residences — talk to your tax advisor about your specific situation before you close.

Brokerage commission

I'll be direct here: commissions are fully negotiable and not set by law. There is no standard, customary, or fixed rate — not in New Jersey, not anywhere. The New Jersey Real Estate Commission and New Jersey Realtors® are both explicit on this point, and antitrust guidance from the Federal Trade Commission prohibits any suggestion of "going rates."

What you agree to pay is stated in your listing agreement — that's the document that governs the relationship. Any compensation a seller chooses to offer a buyer's agent is optional and separately negotiable; it is not an automatic add-on, and it is not shared on the MLS. If you want to know what a listing arrangement with me would look like for your home, that's a conversation — not a number on a blog.

Real estate attorney fees

New Jersey is an attorney-review state. The standard New Jersey Realtors® contract includes a three-business-day attorney review clause: after an offer is accepted, either party's attorney can disapprove the contract or propose modifications via a rider. This is not just a formality — it's one of the most important consumer protections in the transaction.

While retaining an attorney isn't legally required, it is standard practice in Middlesex and Somerset counties, and the New Jersey State Bar Association strongly recommends it. Your attorney handles contract review, title issue resolution, and closing document sign-off. Attorney fees are set by the individual attorney — get a clear quote upfront, and factor it into your planning.

Title company and settlement fees

In Central New Jersey, a title agency handles the title search, identifies liens and municipal charges, coordinates mortgage payoffs, prepares the closing disclosure, disburses funds, and sends the deed for recording with the county clerk. Per the New Jersey Department of Banking and Insurance, title insurance premiums are filed and regulated statewide, which keeps the premium structure relatively uniform — though ancillary fees (search fees, wire fees, deed preparation) can vary by agency.

On the seller's side, title-related costs typically include:

• Deed preparation
• Mortgage payoff coordination and wiring fees
• Recording fees for the release of your existing mortgage (paid to the Middlesex County Clerk or Somerset County Clerk, depending on your property's location)
• Any outstanding liens or judgments surfaced in the title search

For higher-value transactions — common in parts of Somerset County — expect more stringent title scrutiny, including possible survey requirements, flood certifications, and policy endorsements. Properties near the Raritan River and its tributaries in both counties may trigger flood insurance questions, and sellers may need to provide historical flood information in their disclosure.

Municipal inspection fees and certificates

This is one of the costs that surprises sellers who've never sold in New Jersey before. Many municipalities in Middlesex and Somerset counties require one or more of the following before closing:

• Smoke detector and carbon monoxide certificate — required in virtually all NJ municipalities
• Certificate of Continued Occupancy (CCO) or similar municipal inspection — required in some towns, not others
• Well and/or septic inspections — required where applicable
• Radon test — sometimes negotiated as a buyer contingency, sometimes a seller expense

The specific requirements — and the lead times to schedule them — vary by town. Edison, New Brunswick, Piscataway, and Somerville each have their own process. I typically start coordinating these as soon as we have a closing date on the calendar, because a delayed municipal inspection can push your closing date.

Seller credits and repair negotiations

Once the buyer's inspection report comes back, you'll likely face a choice: make repairs, offer a credit, or push back. In Central NJ's older housing stock — think Highland Park, Bound Brook, New Brunswick, South Plainfield — inspection reports frequently flag roof age, electrical panel updates, radon mitigation, and basement moisture. Rather than completing every repair before closing, many sellers negotiate a seller credit at closing, which the buyer uses toward their closing costs or post-closing repairs.

Here's what I tell every seller I work with: a few smart must-do fixes before listing will earn you far more than an over-the-top staging overhaul — but not every inspection item needs to be a full repair. In competitive markets around commuter hubs like Metuchen and Edison, sellers with limited inventory on their side sometimes hold firm on credits for cosmetic issues while addressing lender-required or safety items. Every situation is different, and the right strategy depends on your price point, your buyer's financing, and what the market will bear right now.

Seller credits are fully negotiable and must be reflected on the closing statement. They directly affect your net proceeds — which is why I run through this math with every client before we accept an offer.

What the market looks like heading into the second half of 2026

As of July 30, 2026, the most recent publicly available county-level data comes from New Jersey Realtors® Monthly Housing Market Statistics for 2025. That data shows Middlesex and Somerset counties with median sale prices placing most transactions firmly in the mid- and upper-tier RTF brackets — and some Somerset County properties well above the $1 million threshold that triggers the additional RTF component.

According to New Jersey Realtors®, the county dashboard tracks median sales price, closed sales, days on market, and percent of list price by property type. Even with 2025 as the latest full dataset, the pattern is consistent: Central NJ sellers are transacting at price points where every bracket of the RTF schedule matters, and where seller credits and repair negotiations can meaningfully move your net number.

The Seller's Property Condition Disclosure Statement

This isn't a direct cost — but it carries real financial risk if handled carelessly. New Jersey sellers of one- to four-family residential properties are expected to complete a Seller's Property Condition Disclosure Statement, the standardized form used by New Jersey Realtors® and required by local MLS rules in Central NJ. It covers structural systems, mechanicals, roof, basement, environmental conditions, water/sewer, and known defects.

One thing I emphasize with every seller: "as-is" listings do not waive your disclosure obligations. You still must disclose known material defects — prior water intrusion, past repairs, environmental remediation. Incomplete or misleading disclosure is one of the most common sources of post-closing disputes in New Jersey, and the legal exposure under common-law fraud and consumer protection statutes is real. Fill it out completely and accurately, and loop in your attorney if you have questions about a specific item.

Selling a home in Central New Jersey involves more moving parts than most sellers expect — and the difference between a well-prepared seller and one who's surprised at the closing table often comes down to one conversation before the listing goes live. Real estate remains a powerful financial asset, and protecting your equity starts with understanding exactly what comes off the top.

I walk every seller through a personalized review of their cost categories, their net proceeds picture, and their pricing strategy before we ever sign a listing agreement. If you're thinking about selling a home in Piscataway, Metuchen, South Plainfield, Edison, East Brunswick, or anywhere else in Middlesex or Somerset County, let's talk through the numbers specific to your home.
