As of early 2026, the most expensive residential property in Rehoboth Beach is generally considered to be the "Sandaway" estate (1 and 3 Cullen Street), which has been valued and listed at various points for nearly $11 million. This massive oceanfront "compound" is unique because it sits on a double lot and includes a primary residence of over 7,000 square feet and a guest house of nearly 3,000 square feet, totaling 12 bedrooms. In the ultra-luxury market of North Indian Beach and Henlopen Acres, homes frequently range from $5 million to $9 million, but oceanfront status without dunes obstructing the view (a rarity in Delaware) pushes prices to the top tier. Other high-value listings in 2026 include new constructions on Laurel Street and oceanfront condos on the Boardwalk that approach the $5 million mark. These properties are prized for their "private beach" access and proximity to the high-end dining of downtown Rehoboth.
