Moving to Coastal Delaware: The 2026 Relocation Guide

Sussex County grew 16.8% between 2020 and 2025, reaching about 277,000 residents, more than twice Delaware's 7.1% growth over the same period, according to Census estimates. Delaware overall is now one of the ten fastest-growing states in the country. The newcomers are a mix of retirees, second-home buyers, and remote workers, and that steady demand is what keeps the coastal market moving even when rates climb.

The county-wide median sits around $575,000, with Rehoboth Beach closer to $650,000 and roughly six months of supply, which is a balanced market rather than a frenzy. Mortgage context matters too: the 30-year fixed averaged 7.28% as of October 1, up from 6.34% a year ago, so buyers are leaning on price negotiations and rate buydowns more than they were in 2025. The fall rate breakdown walks through what that means for a monthly payment.

Each town has a distinct personality: Lewes for history and walkability, Rehoboth for boardwalk energy, Bethany for the quiet resort feel, Milton for inland charm that's growing fast, and Long Neck for water access at a more attainable price. The community guides cover Lewes, Rehoboth, Bethany, and Fenwick in depth, and the full communities page compares all ten towns at a glance.

Delaware has no state sales tax, property taxes are among the lowest in the country, and Social Security benefits are not taxed at the state level, which is a big part of why retirees keep coming. Combined with the beach lifestyle and proximity to major East Coast cities, it's a package few other coastal markets can match.
