Delaware Beaches — Rehoboth to Fenwick, STR Investment Guide

Area Overview

Delaware's coastal corridor runs from Rehoboth Beach south to Fenwick Island — six distinct municipalities with six distinct STR tax rates, building codes, governance structures, and buyer profiles. The unifying event is the 4.5% state STR tax effective January 2025, which added a uniform baseline to municipal rates that already varied from 3% to 7%. Combined burdens now range from 7.5% (Dewey Beach) to 11.5% (Rehoboth Beach, Bethany Beach). Investors who treat 'Delaware beaches' as a single market with a single tax rate are underestimating or overestimating their net yield by $4K-$8K/yr on $200K gross revenue.

What You Need to Know

STR Tax by Municipality. Rehoboth Beach: 7% local + 4.5% state = 11.5%. Bethany Beach: 7% + 4.5% = 11.5%. Dewey Beach: 3% + 4.5% = 7.5%. South Bethany: 5% + 4.5% = 9.5%. Lewes: 5% + 4.5% = 9.5%. Fenwick Island: 5% + 4.5% = 9.5%. Ocean View: 5% + 4.5% = 9.5%. These are current rates as of Q2 2026 — municipalities retain authority to adjust their local rates independently.

2025 Reassessment Impact. Sussex County's 2025 reassessment from 1974 base values produced 300-400% increases in assessed value in some beach communities. Because Sussex's millage rate is low, the dollar impact is less dramatic than the percentage implies. Buyers should request updated 2025 assessed values and model forward-year tax at current millage rates.

Insurance Cost Gradient. Coastal insurance costs vary significantly by proximity to ocean, flood zone designation, and building elevation. Oceanfront barrier-beach properties (Dewey Beach) face the highest combined wind and flood premiums. Bay-front properties face different flood exposure profiles. Buyers should obtain insurance quotes during due diligence.

Licensing Requirements. Each municipality has independent rental licensing requirements. Rehoboth Beach requires an annual $150 rental license plus Building and Health Code Compliance Certificate. Bethany Beach and South Bethany have their own licensing processes.

Frequently Asked Questions

Which Delaware beach town offers the best STR investment return?

There is no single answer — the best STR yield depends on acquisition cost, gross rental revenue potential, STR tax rate, insurance cost, and HOA structure for the specific property. Dewey Beach has the lowest STR tax (7.5%) and highest per-night rates but highest insurance costs and most severe seasonal concentration. Rehoboth has the highest STR tax (11.5%) and highest occupancy brand but highest acquisition costs. Lewes has a 9.5% STR tax with 55+ community appreciation tailwinds. Investors should model each municipality with property-specific inputs.

How does Delaware's coastal STR market compare to Maryland's Ocean City?

Ocean City, MD operates with a 5% lodging tax plus Maryland's 6% sales tax on purchases and services. On $200K gross rental revenue, Ocean City's 5% lodging tax produces $10K in tax vs. Rehoboth's 11.5% producing $23K. But Delaware's 0% sales tax on furnishings, supplies, and renovations creates savings at the acquisition and operating level that partially offset the higher STR tax. Dewey Beach at 7.5% is competitive with Ocean City on STR tax alone.
