Seller guidance · Somerville, Massachusetts
Selling a home in Somerville.
Two things make Somerville sales different. A large share of the stock is two- and three-family houses, so a meaningful number of sellers are selling a building with tenants in it. And the Green Line Extension repriced parts of the city recently enough that older comparables can be actively misleading.

The deed excise is charged to the seller at $2.28 per $500 of the sale price or any fraction of it, rounding up at each step. On a $900,000 sale it is $4,104.
An attorney is required to close in Massachusetts — commonly $750 to $1,250 for a straightforward transaction. A smoke and carbon monoxide alarm certificate from the local fire department is also required before closing, typically $50 to $100. In a multifamily property every unit must comply, which makes the inspection larger than in a single-family sale.
If you are selling a condominium, the association's 6(d) certificate and resale documents add cost and, more significantly, lead time.
Commission is negotiated rather than standard, and this page does not quote a rate. Buyer-agent compensation has been directly negotiable since August 2024.
Somerville at a glance
- Residential exemption
- Not yet set Somerville offers a residential exemption of up to 35% of the average assessed value of all Class One residential parcels, applied to a taxpayer's principal residence as of January 1. It is not automatic: the Mayor and City Council vote on it at the end of each December. The city states plainly that before December 2026 the status of the exemption for fiscal year 2027 is unknown, and lists the amount as to be determined.

What the deed excise actually costs
Massachusetts charges the deed excise at $2.28 per $500 of the sale price or any fraction of it. That wording is the whole point: the charge is calculated in whole $500 brackets and rounds up, so a sale at $750,001 is taxed on 1,501 brackets rather than 1,500.
Most online calculators model it as a flat 0.456%, which is exact only when the price lands on a $500 boundary. Off a boundary it always understates — though by a small amount, typically under two dollars. The reason to get it right is precision rather than magnitude: a net sheet should tie out to the cent, and a figure that is nearly right is the kind of thing that costs an hour at the closing table. Across a range of realistic Somerville prices:
| Sale price | Deed excise | Flat 0.456% estimate | Understated by |
|---|---|---|---|
| $649,900 | $2,964.00 | $2,963.54 | $0.46 |
| $825,750 | $3,766.56 | $3,765.42 | $1.14 |
| $1,012,400 | $4,617.00 | $4,616.54 | $0.46 |
| $1,149,900 | $5,244.00 | $5,243.54 | $0.46 |
| $1,575,100 | $7,184.28 | $7,182.46 | $1.82 |
| $2,040,600 | $9,306.96 | $9,305.14 | $1.82 |
Calculated from M.G.L. c. 64D §1. Barnstable County is charged at a higher rate. The excise is one line among several — an attorney is also required to close, commonly $750 to $1,250, and the smoke and carbon monoxide certificate typically runs $50 to $100.
Selling with tenants in place.
If your property is tenant-occupied, the leases are part of what you are selling and your buyer's lender will want to see them. Have the actual rent roll, lease end dates, and deposit records ready, and make sure the records are accurate rather than approximate.
Massachusetts security deposit rules are strict and the liability transfers with the property. Deposits and last month's rent must be held correctly, and a buyer's attorney will look at this closely. A compliance gap discovered mid-transaction is a real problem, not a formality.
Showings need planning too. Tenants have a right to reasonable notice, and a building where access is difficult shows badly. Agreeing a workable arrangement with tenants before listing is worth more than any staging.
Timing: comparables and the lease calendar.
When pricing, check whether your comparables predate the Green Line Extension station openings. Parts of Somerville that were transit-poor became walkable to a station, and sales from before that shift can understate current value in those pockets.
For tenant-occupied buildings, the September 1 lease cycle matters. A building whose leases run to the end of August presents differently to an investor buyer than one with staggered or expiring tenancies, and it affects both timing and price.
Allow extra time for the fire department inspection on a multifamily — every unit has to comply, so it is a larger job than in a single-family sale.
Questions sellers ask about Somerville
How much is the deed excise on a Somerville sale?
$2.28 per $500 of the sale price or any fraction of it, paid by the seller. On a $900,000 sale that is $4,104. It rounds up at each $500 boundary.
Can I sell with tenants still in the property?
Yes, and it is common in Somerville. The leases transfer with the property, so have the rent roll, lease end dates and deposit records accurate and ready. Tenants also have a right to reasonable notice for showings, which is worth agreeing before listing.
What happens to security deposits when I sell?
Deposit liability follows the property, so the funds and the records need to transfer correctly. Massachusetts rules on holding deposits are strict and a buyer's attorney will examine them. Any gap is far cheaper to fix before listing than mid-transaction.
Does every unit need a smoke certificate?
In a multifamily, yes — the whole property must comply before closing. That makes the fire department inspection a larger job than in a single-family sale, so schedule it with more lead time.
Are older sale comparables still reliable in Somerville?
Check the date against the Green Line Extension openings. Union Square, East Somerville, Gilman Square, Magoun Square and Ball Square all gained stations, and sales predating that in those areas can understate current value.
What commission will I pay to sell?
There is no standard rate. Buyer-agent compensation has been negotiated directly since August 2024 rather than published in the MLS, and what a seller offers toward it is a separate, deliberate decision.
