The Real Cost of Owning in Avalon, New Jersey
Avalon is a borough of 1,243 residents (2020 census, down 6.8% from 1,334 in 2010) on the northern half of Seven Mile Island in Cape May County, New Jersey, sharing the island with neighboring Stone Harbor to the south. This page does not state a current median home price, active listing count, property tax rate, or rental-rate figure, because none of those numbers were confirmed during this research pass, and inventing them would do a prospective buyer more harm than good. What is confirmed, and worth understanding before budgeting a purchase here, is that Avalon carries a real, independently documented affluent identity: Forbes named Avalon the 65th most expensive ZIP code in the United States in 2007, and the 2010 census recorded a median household income of $88,527, a median family income of $135,781, and a per capita income of $99,655 for the town. Those figures are dated and should not be read as current pricing or current income levels, but they do signal a genuinely upscale market position that shapes every cost category below, from purchase price to insurance to seasonal-rental demand. Avalon is also this site's sixth New Jersey market, and New Jersey's tax structure and coastal rules are treated as genuinely different from the Delaware markets built earlier on this site, nothing is assumed to carry over.

A Sixth New Jersey Market: Still Not Delaware
Avalon is this site's sixth New Jersey market, following Cape May, Wildwood, Wildwood Crest, North Wildwood, and Stone Harbor, and the same caution applies here that applied at each of those: New Jersey's tax structure, coastal-construction customs, and municipal rules are different from Delaware's no-sales-tax system, and nothing about how costs work in a Delaware market should be assumed to carry over to Avalon.
Cape May County and the Borough of Avalon set their own property tax rates and assessment practices under New Jersey law, and New Jersey applies its own state sales tax to purchases made here, a genuinely different structure from Delaware, which has no state sales tax at all. Confirming exactly how those rules apply to a specific property is a job for the Borough of Avalon's own finance office, Cape May County government, and the State of New Jersey directly, not something this page will estimate.
Purchase Price in an Affluent, Historically Documented Market
Avalon's market position is a real, documented data point rather than a marketing claim. Forbes named Avalon the 65th most expensive ZIP code in the United States in 2007, and the 2010 census recorded a median household income of $88,527, a median family income of $135,781, and a per capita income of $99,655 for the town, figures Wikipedia cites in describing Avalon as "one of the most affluent communities along the Jersey Shore" with "some of the most expensive real estate on the East Coast." Washingtonian magazine has also named Avalon the "chicest beach" in the Mid-Atlantic. Those figures are close to two decades old at this point and should not be treated as a current price or income signal, but they do help explain why Avalon functions as a genuinely upscale market, with a year-round population of 1,243 giving way to a summer population as high as 45,000.
This page will not state a current median home price, price-per-square-foot figure, or active listing count, because none was confirmed this research pass. Get current pricing and comparable-sale data from a local real estate agent who works Avalon and Seven Mile Island specifically, since pricing dynamics here can differ meaningfully from neighboring Stone Harbor despite the shared island and shared corporate founding history.
New Jersey Property Tax: A Real Line Item Without an Invented Rate
New Jersey is widely known nationally for comparatively high property tax bills relative to many other states, and any owner in Avalon will pay a property tax bill set through Cape May County and Borough of Avalon assessment practices. That much is structurally certain, and it is likely to be a meaningful line item in a market with Avalon's documented, if dated, affluent-price-tier history. What this page will not do is state a specific current rate or a specific current assessed-value figure for any property, because no such figure was confirmed this research pass.
Before budgeting a purchase, get the current Cape May County and Borough of Avalon property tax rate and the current assessment methodology directly from Cape May County government and the borough's finance office. A local real estate agent who works in Avalon specifically can also walk through recent tax bills on comparable properties.
Insurance and Risk on a Low-Lying Barrier Island
Avalon sits on Seven Mile Island, a barrier island facing the Atlantic Ocean, at just 7 feet of elevation and 4.27 square miles of land — a genuinely low-lying, exposed coastal position shared with Stone Harbor to the south. That geography makes flood insurance and windstorm coverage a real, ongoing cost of ownership rather than an optional add-on, whether the structure in question is a single-family home, a condo, or a small rental property, and a higher-value property carries a correspondingly higher potential loss to insure against.
Avalon also maintains rock jetties and takes part in ongoing beach-replenishment efforts against erosion, a genuine, confirmed piece of the island's coastal-defense picture, though this page does not state a specific current jetty count, project name, cost, or completion date, because none was confirmed this research pass. Get a current flood-zone determination for any specific parcel from FEMA's Flood Map Service Center, and get a current premium quote from a licensed insurance agent familiar with coastal Cape May County property before making an offer.
Maintaining a Barrier-Island Property
Salt air, wind-driven moisture, and a low, storm-exposed elevation put real, ongoing wear on roofing, siding, HVAC, plumbing, and electrical systems in Avalon, whether a property is older beach-cottage stock or a newer, larger build. Regular inspection and more frequent replacement of exterior and mechanical systems than an inland home would need is a structurally reasonable cost category to plan for, even without a confirmed dollar figure, and larger, higher-end homes typically carry proportionally larger maintenance scope.
Avalon's native landscape was originally a juniper forest that has largely disappeared due to development, making hills and native juniper rare in the town today, a genuine before-and-after detail worth knowing about the land itself. This page does not state a specific current renovation-cost figure, permitting timeline, or review process for exterior work, because none was confirmed this research pass. Get a full inspection from someone experienced with older Jersey Shore construction, and ask the Borough of Avalon's building and zoning office directly what review applies to a specific property before buying.
Seasonal-Rental Income Potential in an Upscale Market
Avalon's summer population climbs as high as 45,000 against a year-round population of just 1,243, and that seasonal surge is the demand base behind any short-term or seasonal-rental strategy here. Combined with the town's documented, if dated, affluent-market history and its shared draw with neighboring Stone Harbor on Seven Mile Island, this is a market where seasonal-rental demand appears structurally real, even though this page cannot state a specific occupancy rate or weekly rental figure.
A seasonal-rental strategy in a market like this carries real cost categories worth planning for: property management and turnover between guests, seasonal staffing and cleaning costs, higher wear on furnishings and systems from short-term guest turnover, and insurance or licensing requirements that can differ for rental use versus owner-occupancy, generally scaling with a property's size and finish level. This page does not state a specific rental rate, occupancy percentage, or management-fee figure, because none was confirmed this research pass. Ask a local property manager and a local real estate agent who works short-term rentals in Avalon specifically for current numbers before budgeting a purchase intended for seasonal income.
Adding It Up: What Is Real, and What We Will Not Invent
What is confirmed and real here: Avalon is a borough of 1,243 residents (2020 census, down 6.8% from 1,334 in 2010) on the northern half of Seven Mile Island in Cape May County, with 4.27 square miles of land and an elevation of 7 feet; Forbes named it the 65th most expensive ZIP code in the United States in 2007; the 2010 census recorded a median household income of $88,527, a median family income of $135,781, and a per capita income of $99,655; Washingtonian magazine named Avalon the "chicest beach" in the Mid-Atlantic; its summer population reaches as high as 45,000; and this is this site's sixth New Jersey market, carrying the same different-from-Delaware tax structure flagged at Cape May, Wildwood, Wildwood Crest, North Wildwood, and Stone Harbor.
What we could not find, and will not fill in with an invented figure: a current median home price, active listing count, typical rental rate, current Cape May County or Borough of Avalon property tax rate, or a specific flood-insurance premium. The 2007 Forbes ranking and 2010 census income figures cited above are real but dated, and should not be treated as current pricing or income levels. Get current numbers directly from a local real estate agent who works this specific borough, current tax and assessment information from Cape May County records and the Borough of Avalon finance office, a current flood-zone determination from FEMA, and a current insurance quote from a licensed agent before budgeting a purchase.
