Wilmington Island is an unincorporated Chatham County community tucked between the Wilmington River and the Savannah River, roughly 12 miles east of downtown Savannah on the road to Tybee Island. It is not a tourist destination — it is a residential island with deep-water dock access, marsh views, and the kind of coastal proximity that generates both short-term vacation rental demand and strong long-term tenant interest from professionals who want to live near the water without paying Tybee prices. For investors, Wilmington Island offers genuine STR optionality in a county regulatory environment that is meaningfully more permissive than the City of Savannah’s overlay district system.

Why Wilmington Island for Investors

Wilmington Island’s investment case rests on three pillars:

1. Coastal proximity without Tybee pricing. Tybee Island’s median home prices have historically run 30–50 percent above Wilmington Island’s. Investors who cannot justify Tybee acquisition costs can access similar coastal and STR demand drivers at a lower entry price — while still marketing properties to guests who want waterfront access and short Tybee Beach commutes.

2. Unincorporated Chatham County STVR framework. Wilmington Island falls outside the City of Savannah limits and is therefore not subject to Savannah’s restrictive 20% per-ward cap system that governs the Downtown and Victorian Historic Districts. In unincorporated Chatham County, STRs are permitted in most residential zones with a $350/year certificate from the Chatham County Department of Building Safety & Regulatory Services, per Chatham County STVR ordinance data. There is no waitlist and no cap on the total number of certificates issued in unincorporated areas. HOA approval is required if applicable; always verify CC&Rs.

3. Durable long-term rental demand. Wilmington Island is a long-established residential community with direct commute access to Savannah’s medical corridor (Memorial Health, St. Joseph’s/Candler), Port of Savannah logistics operations, and downtown professional employment. Long-term tenants who prefer coastal living without the price premium of Isle of Hope or The Landings are a core demand segment here.

Wilmington Island Market Snapshot

Vacation Rental Revenue Context

VRBO lists over 3,500 properties in the Wilmington Island area, indicating established vacation rental market depth. Waterfront and dock-access properties may command materially higher nightly rates than standard residential rentals. Investors should conduct platform-level revenue analysis (AirDNA, Rabbu, or direct Airbnb comps) for specific properties before underwriting STR income.

Cap Rate Estimates

At a $450,000 acquisition price with a $1,700/month stabilized long-term rent, gross yield is approximately 4.5 percent — thin. Buy-and-hold investors in Wilmington Island are typically underwriting to appreciation and coastal demand durability rather than peak cash flow. STR investors who can achieve $3,500–$5,000/month in gross vacation rental revenue on waterfront or near-waterfront properties may see gross yields in the 9–13 percent range before platform fees, management, and carrying costs.

These are illustrative estimates based on market-level data. Individual results will vary. Use the Savannah Property Calculator to model specific scenarios.

Strategy Fit

Short-Term Rental (Unincorporated Chatham): Viable with Diligence

Wilmington Island’s unincorporated Chatham County status makes it one of the most accessible STR operating environments near Savannah. The $350/year certificate requirement is among the lowest regulatory barriers in coastal Georgia. However, investors must confirm three things before assuming STR viability: (1) the specific parcel’s zoning permits STRs, (2) no HOA restriction prevents short-term rentals, and (3) the property can meet the life safety and insurance requirements of the certificate application. See the full STVR Permit Guide for Chatham County requirements and the Chatham County BSRS application documents.

Note: Chatham County proposed updates to its short-term rental ordinance as of April 2026, per a public meeting notice. Investors should confirm current rules with the county before closing.

Buy-and-Hold: Moderate

Long-term rentals at $1,700/month on a $450,000 acquisition produce thin cash flow in a cash-purchase scenario and may require DSCR financing creativity at current interest rates. The buy-and-hold case here is primarily an appreciation thesis — coastal inventory is constrained by water on three sides, and Wilmington Island has historically tracked Tybee trends with a lag. Investors seeking stronger current cash flow should consider Pooler or Richmond Hill as complements in a diversified portfolio. See the Savannah Investor Hub for portfolio construction logic.

BRRRR: Limited

Distressed inventory in Wilmington Island is limited and typically priced at close to market value even in poor condition. The value-add spread that makes BRRRR compelling in Starland District or Southside Savannah does not regularly exist here. Occasional estate sales and dated properties may offer exceptions — but investors should not build a Wilmington Island acquisition thesis around reliable BRRRR execution.

Permits and Regulations

Wilmington Island is in unincorporated Chatham County — not the City of Savannah. This is a critical distinction for STR investors.

Unincorporated Chatham County STR process: – Obtain a Short-Term Rental Certificate from the Chatham County Department of Building Safety & Regulatory Services – Annual certificate fee: $350 ($175 late renewal fee) – Required documents: completed application, Life Safety Compliance Form, HOA affidavit, proof of homeowners insurance (must specifically cover STR use), proof of trash and fire service – No per-ward cap; no waitlist – Certificate is non-transferable; new owners must apply fresh – Platforms like Airbnb and VRBO collect and remit hotel/motel taxes directly in Georgia

The City of Savannah’s 20% ward cap applies only within Savannah city limits. Investors targeting Wilmington Island explicitly benefit from operating outside that system. See the STVR Permit Guide for a side-by-side comparison of city vs. county rules.

Risks

Flood Zone Exposure

Wilmington Island is a coastal barrier island community with significant FEMA Special Flood Hazard Area (Zone AE) coverage. Many parcels — particularly those with water access or near tidal creeks — carry mandatory flood insurance requirements for federally backed mortgages. Flood insurance in Zone AE can add materially to annual holding costs. Always obtain an elevation certificate and review FEMA mapping before making an offer. The Chatham County Engineering Department provides flood zone determination letters upon written request at no charge. See Team 912’s Flood Zone Insurance Primer for what to budget.

HOA Restrictions

A number of Wilmington Island subdivisions and waterfront communities carry HOA covenants. Some explicitly prohibit short-term rentals; others require minimum lease terms of 30, 60, or 90 days. This is the most common cause of STR investment failure in Chatham County communities with HOAs. Verify CC&Rs before committing to any purchase with STR intent.

Regulatory Evolution

Chatham County’s STVR ordinance is active and has been subject to proposed updates as recently as April 2026. The unincorporated Chatham framework is currently more permissive than Savannah’s city limits — but investors should not assume that will remain unchanged indefinitely. Model scenarios that still produce acceptable returns under a more restrictive future framework before acquiring.

Inventory Thinness

With only 41 active rental listings and a relatively small housing stock for a coastal community, rental comps in Wilmington Island are thin. Long-term rent estimates based on small sample sizes carry more uncertainty than in larger submarkets. Verify rent estimates with active listings on Zillow, Realtor.com, and direct MLS data before committing to an underwriting assumption.

School District Notes

Wilmington Island is served by Savannah-Chatham County Public Schools. The specific schools serving a given address will depend on attendance zone. Investors targeting long-term family tenants should confirm current school assignments with the Savannah-Chatham County Public School System before marketing a property to families.
