What Does It Cost to Maintain a St. George Island Beach House?
Owning a beach house on St. George Island costs more than the mortgage. Insurance, property management, maintenance, taxes, and utilities add up fast. Here''s a realistic annual cost breakdown for every budget level.
The purchase price is the number buyers focus on. The annual cost of ownership is the number that determines whether the investment actually works. On St. George Island, a beach house that costs $800,000 to purchase can cost $40,000–$70,000 per year to own before a single dollar of rental income arrives. Understanding those costs before you buy — not after — is the difference between a sound investment and an expensive surprise.

The Full Cost Stack
1. Insurance: $10,000–$45,000/Year
Insurance is typically the largest single cost of owning a St. George Island beach house. Three separate policies are required:
Wind insurance: $5,000–$30,000/year depending on construction year, roof type, opening protection, and Gulf exposure. Post-2002 construction with a hip roof and impact glass sits at the lower end; pre-2002 gable-roof construction at the high end.
Flood insurance: $1,500–$15,000/year depending on flood zone (AE vs. VE), elevation relative to Base Flood Elevation, and whether the property is in a CBRA zone (which requires private flood insurance rather than NFIP).
Homeowners insurance: $2,000–$5,000/year for fire, liability, and non-wind/non-flood perils.
Total insurance range: $10,000–$45,000/year. Gulf-front VE zone properties with older construction sit at the high end. Post-2002 elevated construction in AE zones with favorable wind mitigation features sit at the lower end.
2. Property Taxes: $5,000–$20,000/Year
Florida property taxes are assessed at the county level. Franklin County's millage rate is relatively low compared to the Emerald Coast counties (Bay, Okaloosa, Walton), but assessed values on Gulf-front properties are high.
Estimated annual property taxes:
- $400,000 property: $4,000–$6,000/year
- $700,000 property: $7,000–$11,000/year
- $1,000,000 property: $10,000–$16,000/year
- $1,500,000 property: $15,000–$22,000/year
Important: Florida's homestead exemption (which reduces assessed value for primary residences) does not apply to vacation homes or investment properties. Your assessed value will reflect the full market value of the property.
Also important: Florida's Save Our Homes cap limits annual assessment increases to 3% for homesteaded properties — but again, this does not apply to vacation homes. Your assessed value can increase significantly in a rising market.
3. Property Management: $12,000–$50,000/Year (If Renting)
If you use a property management company — which most absentee owners do — management fees typically run 20–30% of gross rental revenue.
Example: A 3BR Gulf-front property earning $90,000 in gross annual rental revenue at a 25% management fee generates $22,500 in management fees per year.
What management fees cover: Listing on Airbnb, VRBO, and direct booking platforms; guest communication; check-in/check-out coordination; cleaning coordination; maintenance coordination; tourist development tax collection and remittance; owner reporting.
Cleaning fees are typically charged to guests separately and do not come out of your management fee — but verify this with your management company. Cleaning costs on St. George Island run $150–$400 per turnover depending on property size.
4. Maintenance and Repairs: $5,000–$20,000/Year
The coastal environment is hard on buildings. Salt air accelerates corrosion of metal components, humidity promotes mold and wood rot, and the UV exposure degrades exterior finishes faster than inland properties. Budget for:
Routine maintenance: Exterior washing (2–4x/year), HVAC service (2x/year), pest control, gutter cleaning, deck/porch maintenance. Budget $3,000–$6,000/year for routine maintenance on a typical beach house.
Appliance replacement: Coastal salt air shortens appliance lifespans. Budget for appliance replacement on a 7–10 year cycle rather than the 15–20 year cycle typical of inland properties.
Exterior maintenance: Repainting or re-staining exterior surfaces every 5–7 years. Deck and porch refinishing every 3–5 years. Roof replacement every 15–20 years (sooner for older properties). Budget $2,000–$8,000/year amortized for exterior maintenance.
Piling inspection and maintenance: Elevated beach houses sit on pilings that require periodic inspection for wood rot, termite damage, and structural integrity. Budget $500–$2,000/year for piling maintenance and $15,000–$50,000+ for piling replacement if needed.
Septic system: Most St. George Island properties are on septic systems. Budget $300–$500/year for routine pumping and inspection, plus $8,000–$20,000 for drain field replacement if needed (typically every 20–30 years).
5. Utilities: $3,000–$8,000/Year
Even when the property is unoccupied, utilities run continuously:
- Electric: $150–$400/month depending on size and season. Air conditioning in summer is the largest driver.
- Water/sewer: $50–$150/month for properties on municipal water; septic properties have no sewer bill.
- Internet/cable: $100–$200/month — high-speed internet is essential for vacation rental guests.
- Trash: $50–$100/month.
Annual utility cost for a typical St. George Island beach house: $3,000–$8,000/year.
6. HOA Fees (Plantation Only): $1,800–$4,800/Year
Properties in the Plantation pay HOA fees of $150–$400/month covering gate security, common area maintenance, beach access, tennis courts, and the marina. West End and East End properties outside the Plantation have no HOA fees.
7. Tourist Development Tax and Platform Fees (If Renting)
Franklin County tourist development tax: 5% of gross rental revenue, collected from guests and remitted to the county. On $90,000 in gross revenue, this is $4,500/year — but it's paid by guests, not by you, so it doesn't reduce your net income directly. Your management company handles collection and remittance.
Platform fees: Airbnb charges hosts approximately 3% of the booking subtotal; VRBO charges 5–8% depending on the subscription model. These come out of your gross revenue before you receive it.

FAQ
What is the biggest ongoing cost of owning a St. George Island beach house?
Insurance is typically the largest single ongoing cost, running $10,000–$45,000/year depending on the property's construction, flood zone, and Gulf exposure. Property management fees are the second largest cost for owners who rent their properties.
How much should I budget for maintenance on a coastal beach house?
Budget $5,000–$20,000/year for maintenance and repairs on a St. George Island beach house, depending on the property's age, size, and condition. The coastal environment accelerates wear on exterior surfaces, appliances, and structural components compared to inland properties.
Do St. George Island beach houses cash-flow?
Some do, some don't — it depends on the purchase price, the rental income, and the cost structure. Gulf-front properties with strong rental income and favorable insurance profiles (post-2002 construction, AE zone, well-elevated) can generate meaningful net income before mortgage. Properties with high insurance costs (VE zone, older construction, CBRA zone) are harder to cash-flow. Model all costs before making an offer.
What are property taxes on a $1 million beach house on St. George Island?
A $1,000,000 beach house in Franklin County will typically generate $10,000–$16,000 in annual property taxes. Florida's homestead exemption does not apply to vacation homes or investment properties, so the full assessed value is taxable.
Is a property manager worth the cost on St. George Island?
For absentee owners, yes — a property manager handles everything from listing and guest communication to cleaning coordination, maintenance, and tax remittance. The 20–30% management fee is the cost of not having to manage the property yourself from a distance. Self-management is viable for owners with reliable local contacts and comfort managing remotely.
