Key Takeaways
•The Short Answer: On a $950,000 sale (the Cambridge condo median over the past 12 months, per MLS PIN sold data), the model net sheet below shows about $53,537 in selling costs. That leaves $896,463 before you pay off your mortgage.
•The Myth: The Massachusetts deed excise tax is the big bite. At $4.56 per $1,000, it's about $4,332 on that sale.
•The Reality: Commission is the big bite. At 5%, it's $47,500, close to 89% of your total home selling costs.
•The Bottom Line: You can't negotiate the excise rate. You can negotiate commission. Put your energy there.
What Will You Actually Walk Away With?
You list your condo, and an offer lands at $950,000. That's the headline number. It isn't your number.
Your number is whatever reaches your bank account after selling costs — commission, the state deed tax, attorney fees — and after your mortgage gets paid off.
We're using that $950,000 figure because it's the Cambridge condo median over the last 12 months, per MLS PIN sold data. A realistic example, not a luxury outlier.
The excise tax isn't the real problem here. Commission is.
What Goes on a Cambridge Seller Net Sheet?
A seller net sheet is a simple estimate of what you keep after the costs of selling. For that $950,000 sale, the model looks like this:
Cambridge Seller Net Sheet
Compares estimated amount and negotiability for each line item in an October or November Cambridge seller net sheet modeled on a $950,000 condo sale before mortgage payoff.
| Category | Amount | Fixed or negotiable? |
|---|---|---|
| Sale price | $950,000 | Set by the market |
| Commission (5%) | –$47,500 | Negotiable |
| Deed excise (950 × $4.56) | –$4,332 | Fixed by law |
| Seller's attorney (high end) | –$1,500 | Shop around |
| Deed recording fee | –$155 | Fixed |
| Smoke/CO certificate | –$50 | Fixed by town |
| Before mortgage payoff | $896,463 | - |
| Mortgage payoff | Your lender's letter | Fixed |

The deed excise. Statewide seller-cost data lists the deed excise for sellers outside Barnstable County at $2.28 per $500, or 0.456% of the price ($4.56 per $1,000). The same data lists a deed recording fee of $155.00. Some towns also add a Community Preservation Act (CPA) surcharge of $50.00 — a small local fee tacked on at recording, not an accountant's charge.

Your own attorney. Ask whether the attorney running the closing represents you or the buyer's lender. If it's the lender, budget for your own lawyer to review the purchase and sale agreement, help with the deed, and protect your side. Get that quote up front.
Small items that add up. Your condo's management company typically provides a 6(d) certificate, the document showing your condo fees are paid. Your attorney will confirm what's required and any fee attached. Order it early.
You'll also need a smoke and carbon monoxide certificate from the fire department. One nearby city's fee schedule (Melrose) lists about $50 for a single-family home and $100 for a two-family. Check Cambridge's current fee, including for condos, with the fire department directly. The certificate is only good for sixty days, so confirm timing with your agent.

Prorations and payoff. Prorations mean splitting bills like property tax by the closing date. Depending on what you've already paid, you may credit the buyer or receive a credit yourself — your attorney calculates this.
Your mortgage payoff will run higher than your last statement balance, since interest keeps accruing through the payoff date. If you have a home equity line, ask your attorney to confirm it will be formally closed and discharged. Paying it down to zero may not be enough.
The good news: most of these costs come straight out of your sale proceeds at closing. You usually aren't writing separate checks.
Why Does Commission Matter More Than the Excise Tax?
On the model sale, the excise runs about $4,332. Now compare commission:
•At 5.5%: $52,250.
•At 5%: $47,500.
•At 4.5%: $42,750.
Every half-point of commission equals $4,750 on this sale — more than the entire excise tax. The swing between 5.5% and 4.5% comes to $9,500, money that could go toward your next down payment, your move, or just cash reserves.
The excise rate won't budge. Commission can.
Commission is negotiable. Ask your agent how buyer-agent compensation (the pay for the buyer's agent) is handled under current rules. It may be offered by you, requested by the buyer as a concession, or paid by the buyer directly.
The excise is about $4,332 you can't change. Commission is about $47,500 you can.
Fixate on the excise and you'll miss the bigger opportunity sitting right next to it: negotiating commission and buyer-agent pay.
When Does the Standard Net Sheet Break?
Single-family homes. MLS PIN shows a 12-month Cambridge single-family median of $2,505,000. At 5%, commission runs $125,250. The excise comes to $11,423. It grows with price, sure, but commission grows far faster in dollar terms.
Sellers who live out of state. Starting with closings on November 1, 2025, nonresident Massachusetts sellers can face 4% withholding when the sale price hits $1 million or more.

This can catch a professor who moved away but kept a Cambridge unit. If the property sits inside an entity like an LLC, ask a tax advisor whether withholding applies.
On the combined-median sale of $1,102,500, that withholding comes to $44,100. Not necessarily your final tax bill, but a serious cash-flow issue at closing. Talk to a tax advisor early.
What usually doesn't apply. Many Cambridge homes sit on city sewer, so septic inspections often don't come into play — confirm with your attorney. Repair credits are harder to predict and swing widely with the market. Keep a cushion.
What Are the Strongest Arguments Against This Net Sheet?
"5.6% is a generic model, not a real settlement statement."
True. The model's total selling costs come to about 5.6% of the price. Each half-point of commission shifts that total by $4,750, so the percentage is only as good as the commission you actually agree to.
Separate fixed costs from negotiable ones. The excise rate is set in stone. Attorney fees and certificates are small potatoes. Commission and buyer-agent pay are the real moving parts — they vary deal to deal, so treat 5% as a placeholder and swap in your own number.
"Which median should I use?"
MLS PIN shows $1,102,500 for Cambridge homes and condos combined, and $950,000 for condos alone. Medians from different datasets and time windows can differ by well over $100,000, so neither figure is actually your price. Start from recent sold comparables in your neighborhood, ideally from the last few months.
Don't rely on your assessed value either — in Cambridge, it can differ sharply from market value.
"$896K is not what I actually net."
Correct. That $896,463 figure lands before your mortgage payoff and any capital gains tax. Your lender provides the payoff; your tax advisor handles the capital gains piece. A real net sheet has three layers:
1. Selling costs
2. Loan payoff
3. Tax planning
What Should You Do Before Signing a Listing Agreement This Fall?
•Get a written net sheet before you list, not after you accept an offer.
•Interview at least two agents and compare their net sheets side by side.
•Treat the excise as fixed. Negotiate commission and buyer-agent pay instead.
•Line up your timing if you're buying next — your deposit may be due before your proceeds arrive.
Location, condition, and transit access help set your sale price. Closing costs decide how much of it you actually keep.
Could Massachusetts Transfer Taxes Change Later?
Maybe. The Mass. Budget and Policy Center's September 14, 2026 report points to nearby states with tiered fees. Rhode Island doubles its rate above $800,000. Maine more than doubles above $1 million. Connecticut triples above $2.5 million.
The report presents these as examples from other states, not predictions for Massachusetts. Confirm the current state rate with your attorney before you close.
The excise tax is a small, fixed line. Commission is the big, flexible one.
Don't spend your energy fighting a tax you can't change. Focus on the terms you can actually negotiate. If you're thinking about selling in Cambridge, ask for a property-specific net sheet before you list. It's the fastest way to see what you'll really walk away with.
