Seven Mile Island is a barrier island in Cape May County, New Jersey, home to Avalon (northern borough) and Stone Harbor (southern borough). It spans roughly 7 miles along the Atlantic coast, bordered by Townsends Inlet to the north and Hereford Inlet to the south. It is accessible from the Garden State Parkway and sits approximately 90 minutes from Philadelphia and 2.5 hours from New York City.

The island has approximately 8,709 dwelling units: 5,281 in Avalon and 3,428 in Stone Harbor. Typically only about 6% are on the market at any given time — inventory here is consistently tight, which is part of what makes the market so distinctive and so durable.

Stone Harbor typically commands a slightly higher median due to its smaller inventory and boutique character. Avalon has more new-construction luxury homes and a wider price range, with single-family inventory running from under $500K to over $11.9M. Both markets have their own rhythm — the right answer depends on how you intend to use the home and what you're optimizing for.

The strongest listing window is April through Memorial Day, when buyers begin serious summer shopping and inventory is still manageable. Secondary windows include early fall (September) for buyers targeting the following summer, and discreet off-season listings for motivated sellers willing to work with a smaller but more committed buyer pool. The right timing depends on your situation — we'll advise based on your specific property and goals.

Absolutely — a significant portion of Seven Mile Island's buyers come from the Philadelphia, New York, and Washington D.C. metropolitan areas. We're well-practiced at representing remote buyers through detailed video walkthroughs, comprehensive market briefings, and trusted local vendor networks for inspections, attorney review, and closing coordination. Distance is not a barrier to a well-run transaction.

As a barrier island, every property on Seven Mile Island carries some flood insurance consideration. Zone designations vary considerably by block, elevation, and proximity to the bay or ocean — with meaningful differences in insurance premiums, build requirements, and resale implications. This is an area where we provide specific, property-level guidance rather than generic advice. Elevation certificates and flood zone maps are reviewed for every property we represent.

Yes. Seven Mile Island has one of the most mature and lucrative summer rental markets on the East Coast. Ferguson Dechert has long been the island's #1 brokerage for sales, rentals, and investments. The Dan Bowersock Group manages its own rental portfolio in-house — so investment buyers receive a seamless path from acquisition through cap-rate analysis, revenue projections, and ongoing rental management under one roof.

The most accurate valuation comes from a direct conversation with someone who knows every block on the island. Automated estimates don't account for flood zone premiums, bay vs. ocean positioning, construction quality, or the quiet-market dynamics that affect true Seven Mile pricing.

National platforms aggregate listings. They don't negotiate, they don't know which blocks have drainage issues, and they don't call you back on a Sunday. Kim provides individual representation — active, accountable, and specific to your situation. Backed by the Ferguson Dechert network, her clients gain access to the island's largest buyer database, off-market opportunities, and the kind of local institutional knowledge that a national algorithm simply cannot replicate.
