Cohasset, MA Buying Process: Brokerages, Taxes
Cohasset is the smallest, most affluent, and highest-priced town in this stretch of the South Shore -- a compact village built around a historic common, a working harbor, and the offshore Minot's Ledge Light, in Norfolk County rather than the neighboring Plymouth County towns most people lump it in with. Buying here works best when you start with agents who actually work Cohasset regularly, verify pricing directly from current sources rather than secondhand figures, understand how Massachusetts' Proposition 2½ sets the town's tax rate, and take a close look at a live, unresolved local historic-district proposal before you assume you know what the rules will look like for exterior changes in the village core. This page walks through those steps in general terms. It is educational information, not legal or financial advice -- pair it with a Massachusetts-licensed real estate attorney and a local agent before you rely on any of it in an actual transaction.
Start With Cohasset's Named Local Brokerages
Two brokerages have a confirmed dedicated presence in Cohasset. William Raveis Real Estate maintains a dedicated Cohasset office listing (raveis.com/office/ma/cohasset/34803) with its own agent directory. Coldwell Banker Realty lists a Cohasset-area office (coldwellbanker.com/city/ma/cohasset/offices).
Search results also surfaced several smaller, Cohasset-focused independent agents and teams -- names like Frank Neer, Coastal Neighborhoods, Cody Rohland, the Chubb Realty Group, and Lindo Realty Group came up repeatedly. These appear to be individual agent or team websites rather than confirmed brokerage offices with their own physical Cohasset addresses, so this page does not present any of them as an established local brokerage. If an agent from one of these names, or any other firm, approaches you, ask directly whether they operate a local Cohasset office or simply cover the town from elsewhere, and ask how many Cohasset transactions they have closed recently.
Verify Current Zillow and Redfin Figures Yourself
At the time of the research behind this page (a May 31, 2026 data date), Zillow showed 34 homes for sale in Cohasset and a median list price of $1,891,667 -- by a wide margin the highest median list price confirmed for any town in this South Shore cluster's own research. Zillow's own home-value index (ZHVI) stood at $1,474,056, up 5.2% year-over-year, also the highest average home value in the cluster. Unlike Duxbury, Marshfield, and Scituate, which each had a specific "typical days to pending" figure on their own Zillow pages, Cohasset's page showed no figure at all (displayed as "--") at that same data date -- a build agent or buyer should not assume this means homes sit longer, only that the metric was not populated when this page's research was pulled, and should check the live Zillow page directly for a current figure.
Redfin maintains its own Cohasset housing-market page, but a direct median-sale-price or days-on-market figure from Redfin was not successfully pulled during the research behind this page (the page returned a client error on the attempted fetch). Pull both Zillow's current figures and Redfin's median-sale-price and days-on-market data yourself before you set a budget. Treat Census figures (a 2020-2024 ACS median home value of $1,318,900) and Ownwell's own figure (a median home value of $1,098,300, dated April 2026) as reflecting different methodologies and vintages from Zillow's ZHVI, not a single agreed-on number -- three credible sources, three different figures, and none of them should be blended into one unsourced "the Cohasset home value" claim. If you are shopping the premium waterfront micro-market sometimes called the "Gold Coast" (running along Jerusalem Road, Atlantic Avenue, and Nichols Road), expect it to run well above the town-wide figures above -- a real-estate-marketing source put recent listings there in the roughly $1.9 million to $5.3 million range, but treat that as directional, marketing-vintage data rather than an authoritative index.
Understand How Proposition 2½ Sets Cohasset's Tax Rate
Massachusetts does not set a statewide property tax rate. Instead, Proposition 2½ (a 1980 ballot law) caps how much total property-tax revenue a town may raise each year: the levy cannot exceed 2.5% of the town's total assessed value, and year-over-year levy growth is generally capped at 2.5% plus revenue from new construction, unless voters approve an override. Each town's assessors then divide that year's allowed levy by total assessed value to set an annual tax rate per $1,000 of assessed value.
Cohasset's confirmed rate was $11.58 per $1,000 of assessed value in FY2025 -- the highest of any town in this South Shore cluster's own research (compare Duxbury's $10.14, Marshfield's $9.90, and Scituate's $9.99). Combined with Cohasset's high home values, that rate helps explain why one property-tax tracking source put the town's median annual tax bill at roughly $12,718, well above the other towns in this cluster. FY2023, FY2024, and FY2026 Cohasset-specific rates were not confirmed during the research behind this page -- pull them directly from the Town of Cohasset Assessors' Office or the Massachusetts Department of Revenue's Division of Local Services before you budget carrying costs on a specific property, rather than assuming the rate has stayed flat.
The Live Village Local Historic District Proposal, and an Unconfirmed MBTA Communities Question
Before you buy in or near Cohasset Village, it is worth understanding a genuinely unresolved local process. Cohasset's existing Cohasset Common Historic District (National Register-listed in 1996) already covers the town common itself, but it does not cover the village's own commercial and civic core, which has served as the town's business and civic hub since the late 1700s. The town is now studying a proposed "Village Local Historic District" that would extend historic-review protections to that core. A Select Board study committee was formed in 2025, chaired by Woody Chittick, with the Barrett Planning Group engaged as a planning consultant and multiple public forums already held. A potential Town Meeting vote is anticipated for fall 2026, and, as with any Massachusetts local historic district, adoption would require a two-thirds majority. This page cannot tell you how that vote will turn out -- only that it is a live, unresolved process as of this writing, and if you are considering a property in the village core, it is worth asking directly whether it would fall inside the proposed boundary and what that could mean for exterior-modification or renovation rules if the district is adopted.
Separately, Massachusetts law required every community served by the MBTA -- which includes Cohasset, via its own in-town Greenbush Line station -- to address the state's MBTA Communities Act zoning mandate in some fashion. This research pass did not confirm Cohasset's own compliance status one way or the other, unlike Marshfield's well-documented contentious fight (a December 2024 no vote, followed by a lost court challenge) or Scituate's cooperative April 2025 compliance. Do not assume Cohasset's status mirrors either neighbor's -- check directly with the Town of Cohasset's planning office or the state's Executive Office of Housing and Livable Communities for the town's current standing before you factor future housing supply into your decision.
This Is General Information, Not Legal or Financial Advice
Everything on this page is general educational information about how the buying process tends to work in Cohasset, not legal, financial, or tax advice, and it is not a substitute for professional counsel on an actual transaction. Retain a Massachusetts-licensed real estate attorney before you sign a purchase agreement, and work with a licensed local agent who can confirm, for your specific parcel: current listing and comparable-sale prices direct from Zillow and Redfin, the current tax rate, flood-zone status (this research pass could not confirm Cohasset's specific FEMA flood-zone designations or Community Rating System class, so ask directly if the property is anywhere near the water), the current status of the Village Local Historic District proposal and MBTA Communities Act compliance, and the property's permit and deed history at the town's own records office.
Standard buying-process steps -- a home inspection, securing financing, and a closing handled by a real estate attorney -- apply in Cohasset as they do elsewhere in Massachusetts. Cohasset's combination of the cluster's highest home values and tax rate, a real but currently unresolved historic-district proposal for the village core, and an unconfirmed MBTA Communities Act status means the due-diligence questions above are worth working through early -- local agent and verified pricing first, tax mechanics second, and the historic-district and zoning questions third -- rather than skipping ahead to an offer before you have answers.

Local brokerage information (William Raveis Real Estate's dedicated Cohasset office at raveis.com/office/ma/cohasset/34803 and Coldwell Banker Realty's Cohasset-area office at coldwellbanker.com/city/ma/cohasset/offices) reflects this site's own research; several smaller, Cohasset-focused independent agent and team names (Frank Neer, Coastal Neighborhoods, Cody Rohland, Chubb Realty Group, Lindo Realty Group) surfaced during research but could not be confirmed as distinct brokerage offices with their own physical Cohasset addresses, so they are not presented as established local brokerages here. Zillow's snapshot (34 homes for sale, a median list price of $1,891,667, and a ZHVI of $1,474,056 up 5.2% year-over-year) reflects a May 31, 2026 data date fetched directly during this research; Cohasset's "typical days to pending" metric was not populated on the page at that date (shown as "--"), unlike Duxbury, Marshfield, and Scituate, which each had a specific figure per those towns' own research. Redfin's market page for Cohasset returned a client error on the attempted fetch and is not cited here. The Census figure ($1,318,900, 2020-2024 ACS) and Ownwell's figure ($1,098,300, dated April 2026) are cited as separate, differently-sourced figures, not blended with Zillow's ZHVI. The Proposition 2½ mechanism is a matter of Massachusetts law; Cohasset's own FY2025 tax rate ($11.58 per $1,000, per massachusettsalmanac.com's Massachusetts Communities Tax Rate Fiscal Year 2025 table, cross-cited in this cluster's own prior research files) is the only fiscal year confirmed in this research -- FY2023, FY2024, and FY2026 rates were not confirmed and should be pulled directly from the Town of Cohasset Assessors' Office or the Massachusetts Division of Local Services. The median annual tax bill figure (approximately $12,718) is per Ownwell's own property-tax trends page. The proposed Village Local Historic District (Select Board study committee formed 2025, chaired by Woody Chittick, with the Barrett Planning Group as consultant and a potential fall 2026 Town Meeting vote requiring a two-thirds majority) is per South Shore Times reporting dated June 22, 2026; this page does not assert an outcome for that vote. Cohasset's own MBTA Communities Act compliance status was not confirmed during this research and is presented here as an open question worth checking directly, in contrast to Marshfield's documented non-compliance vote and lawsuit or Scituate's documented April 2025 compliance. This page is general educational information, not legal or financial advice -- confirm current prices, tax figures, and historic-district and zoning status directly with the relevant sources, and retain a Massachusetts-licensed real estate attorney before relying on any of it in a transaction.
