The Short Answer

What Is the Cost of Living in Sussex County, Delaware?

Sussex County is approximately 3% above the national average cost of living (Redfin, 2024) — significantly below comparable coastal resort markets. Its most notable advantage: no sales tax, low property taxes, and 100% Social Security income exemption.

The median home price of $397,800 (census-based) and a typical property tax bill of $1,216/year put Sussex County in an accessible range for retirees and families relocating from higher-cost Northeast markets. Coupled with Delaware's lack of a sales tax and favorable income tax treatment, the effective cost of living is lower than the sticker price suggests.

What Each Major Cost Category Looks Like in Sussex County

Housing, taxes, utilities, healthcare, and transportation — the full picture for 2026.

Housing — $397,800 Census Median

The census-based median ($397,800) includes older transaction data. Active market median is $485,000 as of January 2026. Rental market ranges from approximately $1,400–$2,200/month for a 2BR inland to $2,800–$4,500+ for coastal units. Seasonal rentals skew the rental market significantly in beach communities.

Utilities — Delmarva Power Electric

Most of Sussex County is served by Delmarva Power (an Exelon company) for electricity. The majority of rural properties in Sussex County are on private well and septic — no public water/sewer bill. Natural gas is limited to populated areas; propane is common for heat and cooking in rural areas.

Transportation — Car-Dependent Outside Rehoboth

Sussex County is largely car-dependent. Fuel costs track national averages. The DART First State bus system serves Lewes, Rehoboth, and Georgetown. The Junction & Breakwater Trail and Lewes-to-Rehoboth trail are popular but are recreational routes, not commute infrastructure.

Healthcare — Beebe Medical Center

Beebe Medical Center in Lewes is the primary hospital for coastal Sussex County. Nemours Children's and ChristianaCare have locations in the county. Healthcare costs track national averages for outpatient care. Long-term and specialist care may require travel to Wilmington or Philadelphia.

Groceries & Retail — No Sales Tax Advantage

Delaware's 0% sales tax means groceries, clothing, electronics, and household goods are all purchased at face price. Households moving from Maryland (6%), New Jersey (6.625%), or Pennsylvania (6%) save meaningfully every year on routine purchases.

Seasonal Premium vs. Year-Round Living

Coastal communities carry a significant premium over inland Sussex County. Year-round residents in communities like Georgetown, Seaford, and Milford have materially lower housing costs than those in Rehoboth Beach, Lewes, or Bethany. The choice between coastal and inland is the single biggest cost-of-living variable in Sussex County.
Population Growth Context

Sussex County Has Grown More Than 25% Since 2000

The 65+ population is projected to grow an additional 41% by 2040 — Sussex County is the fastest-growing county in Delaware.

Sussex County has added more than 25% to its population since 2000, driven by retiree migration from the Northeast corridor and remote-work relocation. That growth has pushed housing costs upward — but Sussex County remains substantially more affordable than comparable coastal markets in New Jersey, Connecticut, and the Maryland/Delaware beaches to the north.

The 65+ population is projected to grow 41% through 2040 (U.S. Census Bureau projections). Infrastructure — healthcare, schools, utilities, roads — is actively expanding to meet demand, which creates both opportunity (new construction, development) and constraint (traffic, permitting backlogs).

Common Questions

Cost of Living FAQ

For many Northeast retirees, yes. Social Security income is fully exempt from Delaware state income tax. Property taxes are low ($1,216/year typical). The absence of a sales tax eliminates ongoing friction costs. Delaware also offers a senior property tax credit. The biggest variable is housing cost — coastal Sussex is not affordable on Social Security alone, but inland communities like Georgetown, Seaford, and Milford are within range.
Yes — Delaware has a graduated state income tax ranging from 2.2% to 6.6% on income above $60,000. However, significant exemptions apply: Social Security is fully exempt, pension income has a substantial exclusion, and the standard deduction provides meaningful relief. Most retirees with Social Security and pension income pay little to no Delaware income tax.
Sussex County's last county-wide property reassessment was in 1974, meaning assessed values are dramatically below market values. The effective property tax rate is approximately 0.47% of market value — one of the lowest in the nation. A home worth $485,000 at market value typically pays around $2,280/year in total property taxes (county, school, and municipal where applicable).
