Selling a house in Wellesley, MA costs several percent of the sale price, and the largest line item is real estate commission, which is negotiable. On a $2.1 million sale — roughly the town’s median single-family price (MLSPIN, 2025) — the Massachusetts deed excise tax alone is about $9,576, and every 1% of commission equals $21,000. Below is each cost a Wellesley seller should expect, with a worked example, so nothing surprises you at the closing table.
The Short Answer: What Wellesley Sellers Pay
Real estate commission: negotiable, and usually the largest cost of selling.
Massachusetts deed excise tax: $4.56 per $1,000 of the sale price in Norfolk County, where Wellesley is located.
Closing attorney: Massachusetts closings are attorney-led, so the seller pays for legal representation.
Compliance certificates: a smoke and carbon monoxide certificate from the fire department, plus a Title 5 septic inspection if the home has a septic system.
Mortgage payoff and adjustments: payoff of any loan, discharge and recording fees, and prorated taxes and utilities.
Preparing the home: painting, repairs, landscaping, staging, and cleaning — the most variable category.
1. Real Estate Commission
Commissions in Massachusetts are set by agreement between you and your listing agent, not by law. Since the National Association of Realtors settlement changes took effect in August 2024, buyer-agent compensation can no longer be displayed on the MLS, and sellers are not obligated to pay a buyer’s agent. Many sellers still choose to offer compensation privately to attract buyers, and your listing agreement now spells out whether you are doing so and how much. Ask every agent you interview for a written breakdown of both pieces: the listing fee and any compensation offered to the buyer’s agent.
The math is simple but sobering. On a $2.1 million sale, each 1% of total commission is $21,000. That is why it is worth comparing what each agent’s fee actually buys you in pricing strategy, marketing, and negotiation. For a framework, see 12 questions to ask before you hire an agent in Wellesley.
2. Massachusetts Deed Excise Tax
The seller pays a deed excise tax — often called “transfer stamps” — of $4.56 per $1,000 of the sale price in most Massachusetts counties, including Norfolk County. It is collected at closing when the deed is recorded. On a $2.1 million sale, the tax is $9,576. The rate is higher on Cape Cod and the islands, but that does not apply to Wellesley sellers.
3. Closing Attorney Fees
In Massachusetts, an attorney typically manages the title review, the purchase and sale agreement, and the closing itself. Fees for a straightforward residential sale are commonly quoted in the range of roughly $800 to $1,100, and they can run higher for complex situations such as estate sales, trusts, or title issues. Your agent can suggest experienced Wellesley closing attorneys from our Trusted Resources directory.
4. Compliance Items: Smoke/CO Certificate, Title 5, and Lead Paint
Smoke and carbon monoxide certificate. Massachusetts requires a certificate of compliance from the local fire department before closing. Fees are typically modest — often about $50 to $100 depending on the town — but a failed inspection means a repair and a re-inspection, so schedule it early rather than the week of closing.
Title 5 septic inspection. This applies only if the property has a septic system. Inspection costs are commonly around $800, and a failed system can turn into a significant repair or replacement negotiation. Most of Wellesley is on municipal sewer, but some properties are not.
Lead paint. Homes built before 1978 come with federal and Massachusetts lead-paint disclosure requirements. The paperwork is inexpensive, but it must be handled correctly, and your attorney and agent will coordinate it.
5. Mortgage Payoff and Closing Adjustments
Your closing statement will show the payoff of any existing mortgage along with discharge and recording fees. Property taxes are prorated between you and the buyer as of the closing date. In older Wellesley homes, you may also be reimbursed for heating oil left in the tank, and condominium sellers should expect prorated condo fees and a request for the association’s paperwork. Wire, courier, and administrative charges typically add a few hundred dollars.
6. Getting the Home Ready to Sell
Preparation is the most variable category, and the one where good advice saves the most money. Common expenses include fresh paint, minor repairs, landscape cleanup, professional cleaning, staging, and sometimes a pre-listing inspection. The goal is not to renovate; it is to spend where buyers will pay you back and skip what they will not.

These figures are illustrative estimates, not a quote, and they exclude your mortgage payoff, preparation costs, and any taxes on your gain.
Sale price: $2,100,000
Deed excise tax at $4.56 per $1,000: $9,576
Closing attorney (estimate): about $1,000
Smoke/CO certificate (estimate): about $100
Wire, courier, and administrative charges (estimate): about $350
Subtotal, excluding commission and preparation: roughly $11,000
Commission: $21,000 for every 1% agreed
Do Not Forget Taxes on Your Gain
Federal law allows many homeowners to exclude up to $250,000 of gain on the sale of a primary residence, or $500,000 for married couples filing jointly, if they meet the ownership and use tests. Gains above the exclusion can be taxable at federal and Massachusetts rates. Keep records of capital improvements — additions, a kitchen renovation, a new roof — because they can raise your tax basis and reduce the taxable gain.
