The Real Cost of Owning Property on Nantucket

Purchase Price: A Real 2025 Number, and What Still Needs Confirming

The clearest current figure available for this page comes from Nantucket Current, citing Fisher Real Estate's 2025 Nantucket Real Estate Year in Review: the median home sale price on Nantucket in 2025 was $3.5 million, with more than $1.8 billion in real estate sold across 417 transactions for the year. That's a dated, sourced, outlet-attributed figure, and it's consistent with how every other source checked for this page frames the island - Zillow, Redfin, Bernadette Meyer's market blog, robbreport's million-dollar-home market rankings, and CNBC's coverage of markets where seven-figure listings are standard all independently describe Nantucket as one of the most expensive housing markets in the country.

What this page cannot responsibly give you is a live Zillow Home Value Index number or a current Redfin median-price figure - both exist (Zillow maintains a dedicated ZHVI page for Nantucket, MA), but neither could be independently retrieved this pass. For a sense of scale rather than a substitute for Nantucket's own number: this site's own Barnstable, MA research (a Cape Cod town, not an island) put Barnstable's Zillow ZHVI at $689,450 as of January 2026 - every indication from the sources above is that Nantucket's figure runs several multiples higher than any Cape Cod town this site has covered. Get a current MLS pull or ZHVI check from a Nantucket-focused agent before treating any single number here as an appraisal.

Property Tax: A Low Rate That Doesn't Mean a Low Bill

Nantucket runs one of the more counterintuitive property-tax stories on this site. Nantucket Current published a piece literally titled "Nantucket Property Tax Rates Going Down, But Tax Bills Set to Increase," and a local real-estate blog separately ran one asking "Why Are Property Taxes So Low on Nantucket?" - both headlines point at the same real, actively discussed local dynamic: Nantucket has one of the lowest residential mill rates in Massachusetts, but that low rate sits on top of an extraordinarily high total assessed valuation base. The town collects what its budget needs from a low per-$1,000 rate, while individual owners still see their tax bills climb, because each property's assessed value is so high that even a small rate covers a large bill - and rising valuations can push bills up even when the rate itself falls.

This page is not going to guess at the exact current rate. The Town of Nantucket publishes an official Tax Rate History document and maintains a live Tax Rate Calculator (atmtaxratecalculator.nantucket-ma.gov), and that calculator - not a market blog, and not this page - is the right source for the specific dollars-per-$1,000 figure that applies to a given fiscal year. Confirm the current rate directly with the Nantucket Assessor's Office or the town's calculator tool, and treat any tax-planning decision as one to make with a licensed Massachusetts tax professional, not from a single blog post or news headline.

Short-Term Rentals: The Tax Stack, and a Number That Needs One More Check

Massachusetts' statewide short-term rental law, Chapter 337 of the Acts of 2018, applies to Nantucket rentals the same as every other Massachusetts municipality: a 5.7% state room-occupancy excise, plus mandatory registration. On top of that, a local real-estate blog post is titled "Short Term Rental Tax now 11.7%" - arithmetically consistent with the 5.7% state excise plus a 6% local-option excise. What that figure doesn't clearly resolve is whether Nantucket also carries the additional 2.75% Cape Cod & Islands Water Protection Fund excise that applies to Barnstable County towns (which would put Nantucket's stack closer to 14.45%, matching Barnstable's). The fund's own name - Cape Cod and Islands - suggests it could apply to Nantucket County, but this page could not confirm either way this pass. Before budgeting a specific STR tax percentage, confirm the current, applicable rate with the Massachusetts Department of Revenue or the Nantucket Assessor's office directly, since these rates are set by vote and can change year to year.

STR revenue itself has been documented as genuinely volatile rather than steadily rising: Nantucket Current reported the island's short-term rental tax revenue "Plunged 27% in Summer 2024," then separately reported it "Rebounded In Summer 2025, But Still Fluctuating." Layered on top of the tax mechanics is a real, ongoing civic fight: Town Meeting voters have repeatedly rejected broader short-term-rental restriction proposals (Nantucket Current: "Voters Again Reject Short-Term Rental Restrictions" and "Stalemate: All Four Short-Term Rental Proposals Defeated"), while separately passing a ban on corporate/LLC ownership of STRs. An "Article 60" STR question is active again heading into the 2026 Town Meeting, with town counsel reportedly flagging some proposed language as legally problematic. Treat this as a real, unresolved, multi-year fight rather than a settled regulatory picture, and confirm the current rules before buying with STR income in the plan.

Erosion-Driven Fire Sales: Real, Separately Reported, Not Fully Reconciled

Coastal erosion on Nantucket is not just an abstract climate-risk story - it has produced multiple, separately reported real-estate transactions where a property lost most of its value in a short window. Fortune reported in March 2024 that a $2.3 million home listing cut its asking price by "a whopping 74%" after rapid shoreline erosion. The Boston Globe/Boston.com reported, in a piece dated to early April 2024, that a different waterfront home, "its beach nearly gone," sold for just $600,000. Nantucket Current, in a separate "Erosion Firesale" story picked up by outlets including the Boston Globe, Fox Business, and Axios, reported a waterfront property assessed at nearly $2 million selling for just $200,000. A further syndicated report described a beach home selling "$1.77 million below market value" - a figure close enough to the $600,000 sale's implied gap that it may describe the same transaction from a different angle rather than a fourth distinct sale.

This page is not going to collapse these into one dollar figure or one property count, because it genuinely could not confirm whether these reports describe two, three, or four distinct homes. What is safe to say: erosion-driven price collapse on Nantucket waterfront property is real, it has happened more than once, and it is documented by name-brand outlets rather than a single blog's claim. Anyone considering a waterfront or bluff-adjacent purchase - particularly in the 'Sconset area, where the Baxter Road bluff and the now-removed geotube revetment have been the subject of a years-long public fight - should get a current erosion-rate and setback assessment from the town's own coastal-resilience office before treating a low asking price as simply a bargain.

The Housing Crisis Behind the Price Tag

A July 2026 Planetizen piece states that over half of homes on Nantucket are for seasonal use, while year-round workers struggle to find housing they can afford on local wages - the blunt tension behind every other number on this page. Real, named institutions are actively working on it: the Nantucket Affordable Housing Trust, Housing Nantucket (a nonprofit whose October 2025 housing-needs assessment reported a 12.3% increase in area median family income for FY24), and the town's own Municipal Housing program, which includes concrete current projects like the Waitt Drive seasonal workforce housing initiative and a Select Board plan to create up to 50 new units for town employees. This is a genuine, ongoing, multi-institution effort, not a single solved program - and it is the context worth keeping in mind alongside any purchase-price or tax number above.

What This Page Can't Tell You

A few real numbers were not confirmable this pass, and this page states that plainly rather than filling the gap with an invented figure. The current Zillow Home Value Index (ZHVI) and Redfin median-price figures for Nantucket were not independently retrieved - rely on the sourced $3.5 million 2025 median from Nantucket Current/Fisher Real Estate above, and confirm a live number with a Nantucket-focused agent. The exact current FY2026 residential tax rate, in dollars per $1,000 of valuation, was not confirmed - use the town's own Tax Rate Calculator or contact the Assessor's Office directly. Whether Nantucket's short-term rental tax stack is 11.7% or 14.45% (depending on whether the Cape Cod & Islands Water Protection Fund excise applies to Nantucket County) is genuinely unresolved here. And whether the several reported erosion fire-sale transactions represent two, three, or four distinct properties was not disambiguated - each is cited separately by outlet above rather than merged into one narrative.

None of this page is legal, tax, or financial advice. For a specific property's assessed value and current tax bill, contact the Nantucket Assessor's Office directly. For current short-term rental rules and tax-stack confirmation, contact the Massachusetts Department of Revenue or the Assessor's office. For an up-to-date price comparison, a Nantucket-focused real estate agent or a live MLS pull is the right source. And for any tax-planning or insurance decision, work with a licensed Massachusetts tax professional and an insurance agent familiar with island risk before making a financial commitment.
