The volume is in the beach towns, Rehoboth, Lewes, Bethany, and Dewey, with Wilmington and Dover as smaller urban markets. It is seasonal and coastal, with rental cottages clustered close to the boardwalk and the bay. Demand is summer-heavy and turnover is high.
Beach wind and floodThe defining Delaware peril is coastal: nor’easter and hurricane wind with tidal and storm-surge flooding along the beaches and bays. Standard policies treat flood as a separate matter, so a property a few blocks from the ocean can be exposed in the exact storm that defines the market. High summer turnover also raises guest-liability frequency.
Delaware claims most often fail on the flood line, carried separately if at all, and on the wind-versus-flood split after a coastal storm. High guest turnover compounds liability exposure. Confirm flood coverage, your named-storm deductible, and your liability limits before the season.
Delaware is a small, beach-driven market, and the rules concentrate in Sussex County. The state has no general sales tax but applies an accommodations tax to transient lodging and added a new statewide lodging tax on short-term rentals at the start of 2025. The beach towns run annual rental-license programs: Rehoboth Beach charges a fee plus a local lodging tax, sets occupancy limits, and requires an annual life-safety self-inspection and pool or hot-tub safety certification, while Lewes and the others run their own licenses and inspections. Liability insurance is widely expected by the towns and the platforms. Confirm the town license and inspection rules, and put the coverage in place, before you buy.
