Cost to Sell a Home in Boston: What You'll Actually Net

What you net from a Boston home sale is your sale price minus your mortgage payoff, the broker compensation you negotiated, the Massachusetts deed excise tax ($4.56 per $1,000 of the sale price), your closing attorney's fee, tax and utility prorations, recording fees, and a few required compliance items. Every line depends on your property, your loan, and your contract, which is why a personalized net sheet beats any rule of thumb.

"What will I actually walk away with?" is the right first question when you start thinking about selling. The answer isn't just sale price minus mortgage. There are several layers of costs between your accepted offer and the wire to your account, and several of them are specific to Massachusetts. Here's every line, which ones are fixed and which are negotiable, and how to build your own net sheet before you set a price.

How much does it cost to sell a home in Boston?

Your cost to sell is the sum of your mortgage payoff, the broker compensation you negotiate, the deed excise tax, your attorney's fee, prorations, recording fees and any required compliance items. Only some of those lines are fixed. The deed excise tax, for example, is $4.56 per $1,000 of the sale price, so on a $900,000 sale it's $4,104.

Key Takeaways

The Massachusetts deed excise tax is $4.56 per $1,000 of the sale price everywhere except Barnstable County, and the seller customarily pays it.
Broker compensation is negotiable and not set by law, and since August 17, 2024, offers of compensation to a buyer's broker can no longer be made on the MLS.
Your mortgage payoff includes interest accrued through the payoff date, so it isn't your statement balance.
The Boston Fire Department asks for at least 10 business days' notice for the smoke and CO inspection.
Compare each Offer to Purchase by net, not just price, and check your attorney's settlement statement against your net sheet line by line.

What costs come out of your sale price?

Six lines come out of the price before the money reaches you.

1. Mortgage Payoff and Any Home Equity Line

Usually the biggest line. Your payoff isn't your statement balance: it includes interest accrued through the payoff date and any lender fees, and a home equity line gets paid off and closed at the same time. Your attorney orders a formal payoff statement good through your closing date.

2. Broker Compensation

Broker compensation is negotiable and not set by law. The listing fee is whatever you agree to in your listing agreement. Since August 17, 2024, offers of compensation to a buyer's broker can no longer be made on the MLS, and any compensation a seller chooses to offer a buyer's broker is a separate, optional decision. Talk through both with your agent before you list, and get the structure in writing.

3. Massachusetts Deed Excise Tax

Under M.G.L. c.64D, Massachusetts taxes recorded deeds at $4.56 per $1,000 of the sale price everywhere except Barnstable County, which has its own rate. In Massachusetts the seller customarily pays it, though the Purchase and Sale Agreement controls. It's one of the few lines you can calculate exactly once you know the price:

Sale price	Deed excise tax
$700,000	$3,192
$900,000	$4,104
$1,200,000	$5,472

4. Your Closing Attorney

Sellers in Massachusetts typically hire their own attorney, separate from the buyer's. Yours reviews and negotiates the Purchase and Sale Agreement, clears title issues, prepares the deed, and makes sure your proceeds are disbursed correctly. Fees are set by the attorney, so ask for a flat-fee quote up front.

5. Prorations and Municipal Charges

Real estate taxes, condo fees, fuel, and prepaid rents on a multi-family are adjusted to the exact closing date, so you may see a credit or a debit. Your attorney also gets a municipal lien certificate showing any open taxes or charges, and in Boston a final Boston Water and Sewer Commission reading. Any open balance comes out of your proceeds.

6. Recording Fees

Recording the deed and discharging your mortgage carry registry fees set by state law. They're modest, but they belong on every net sheet.

Which Massachusetts requirements can affect your net?

Four state requirements can add cost or time: the smoke and CO certificate, the lead paint notification, a Title 5 septic inspection and, for condos, the 6(d) certificate. Smoke and CO certificate. When a home is sold, the local fire department inspects the smoke and carbon monoxide alarms under M.G.L. c.148, §26F and §26F½ and issues a certificate of compliance. In Boston, the Fire Department asks for at least 10 business days' notice and recommends applying as soon as the Purchase and Sale Agreement is signed. Fees and how long a certificate stays valid vary by town. If an alarm or wiring needs upgrading, that cost is yours. See the smoke and CO certificate guide.

Lead paint notification (homes built before 1978). Sellers must give the buyer the Massachusetts Property Transfer Lead Paint Notification, plus any existing inspection reports or letters of compliance, before the Purchase and Sale Agreement is signed. Any deleading work is negotiated.

Title 5 septic inspection. Most Boston homes are on city sewer, so this rarely applies. If your property has a private septic system, it generally must be inspected within two years before the transfer (310 CMR 15.301), and a failed system can mean repair costs and a delayed closing. Arrange it before you list.

6(d) certificate for condos. Under M.G.L. c.183A, §6(d), your condo association issues a statement of any unpaid common charges and assessments on your unit. Closings require it, and any unpaid balance comes out of your proceeds. See the 6(d) certificate guide.

Beyond those specific items, disclose any material defect you know about. Ask your attorney what your sale requires.

Which selling costs are fixed and which are negotiable?

The payoff, recording fees and deed excise rate are set; broker compensation and who pays the excise are negotiated. | Line item | Fixed or negotiated? | Applies to | | --- | --- | --- | | Mortgage and home equity payoff | Set by your loan | Sales with a loan | | Listing broker fee | Negotiated in your listing agreement | All sales | | Buyer's broker compensation | Optional and separately negotiated | If you choose to offer it | | Deed excise tax | Rate set by statute; who pays is negotiable | All sales | | Seller's attorney | Set by the attorney | All sales | | Recording fees | Set by state law | All sales | | Tax, fee, and rent prorations | Calculated by closing date | All sales | | Municipal lien and water/sewer balances | Any open balance | All sales | | Smoke and CO certificate | Required; fee set by town | Residential sales | | Lead paint notification | Required; deleading negotiated | Homes built before 1978 | | Title 5 inspection | Required; repairs negotiated | Homes on septic | | 6(d) certificate and condo balance | Required; any balance owed | Condos |

How do you build a net sheet for your home sale?

Build it in three stages: before you set a price, when offers come in, and before closing. 1. Before you set a price: estimate your payoff, agree on broker compensation, and run the deed excise tax at a few price points. Knowing your net at each price makes the pricing conversation concrete. See how to price your home to sell in Boston. 2. When offers come in: compare each Offer to Purchase by net, not just price. Credits, closing date, and any buyer's broker compensation request all change what you keep. See how to choose the best offer. 3. Before closing: your attorney's settlement statement replaces the estimate with exact figures. Check it against your net sheet line by line.

FAQ

What do sellers pay at closing in Massachusetts?

Your mortgage payoff, the broker compensation you negotiated, the deed excise tax ($4.56 per $1,000 of the sale price outside Barnstable County), your attorney's fee, recording fees, prorations, any open municipal or condo balances, and required compliance items like the smoke and CO certificate.

Who pays the Massachusetts deed excise tax?

The seller customarily pays it, deducted from proceeds at closing. It's negotiable, and your Purchase and Sale Agreement controls. On a $900,000 sale it's $4,104.

Do I need my own attorney to sell in Massachusetts?

Sellers typically retain their own closing attorney to review the Purchase and Sale Agreement, prepare the deed, and protect their interests through closing.

Do I have to pay the buyer's agent after the NAR settlement?

No. Offering buyer's broker compensation is optional and separately negotiated, and offers can no longer be made on the MLS. Some sellers still offer it. It's a strategic decision to make with your agent before you list.

When should I schedule the smoke and CO inspection?

As soon as the Purchase and Sale Agreement is signed. Boston asks for at least 10 business days' notice, and validity periods vary by town, so don't leave it to the final week.

What is a 6(d) certificate?

A statement from your condo association of any unpaid common charges and assessments on your unit. Closings require it, and any unpaid balance is settled from your proceeds.

Does Massachusetts require a seller disclosure form?

Specific disclosures are required: lead paint notification for pre-1978 homes, Title 5 results for homes on septic, and the smoke and CO certificate. Beyond those, disclose any material defect you know about, and ask your attorney what applies to your sale.

The bottom line: what you net depends on your payoff, your negotiated terms and a handful of Massachusetts items, so a personalized net sheet is the most reliable way to know your number before you set a price.
