Thinking about a Folly Beach getaway that pays for itself? Short-term rentals can be a smart way to combine lifestyle and income, but the path is not set-and-forget. Rules change, seasons swing, and coastal costs add up fast. In this guide, you’ll learn how to vet Folly Beach properties for STR eligibility, map seasonality to revenue, and build a clear ROI model that helps you invest with confidence. Let’s dive in.
Start with city rules first
Folly Beach is an incorporated city with its own municipal code and enforcement. City rules govern permits, occupancy limits, parking, safety equipment, and noise. Requirements can change, so you should always verify the latest details on the City of Folly Beach website and in the municipal code before you buy.
Multiple layers may apply to any property. Beyond the city, Charleston County handles certain taxes and business licensing, and the South Carolina Department of Revenue sets sales and accommodations tax guidance. Condominiums and HOAs may also restrict or ban short-term rentals. Confirm every layer for the specific address.
Practical checks for any property
- STR permit or registration required, including documentation, fees, and inspections.
- Zoning rules and whether hosted vs. whole-home STRs are allowed in that zone.
- Minimum and maximum stay requirements, and whether rules change by season.
- Night caps per booking or per year, if any.
- Maximum overnight occupancy rules by bedroom count or square footage.
- Required on-site parking and enforcement details.
- Noise ordinances, quiet hours, and party or event restrictions.
- Local contact or management agent required for 24/7 response.
- Required insurance types and safety equipment like smoke and CO detectors.
- State and local tax registration and remittance procedures.
- Penalties and appeals process for violations.
Seasonality and demand on Folly Beach
Folly Beach is small, popular, and highly seasonal. Summer drives the majority of bookings, tied to family vacations and holiday weeks. Spring break and fall weekends create solid shoulder seasons, helped by Charleston events and milder weather. Winter tends to be slower, though discounted longer stays can help fill the calendar.
Booking patterns typically shift with the calendar. Summer often favors weekly Saturday-to-Saturday stays with higher rates and strong occupancy. Shoulder seasons can support shorter stays, last-minute bookings, and midweek demand. Your minimum-stay rules and pricing should reflect these patterns.
Location and amenities matter. Walkability to the beach, beach access points, decks and outdoor showers, pet-friendly policies, and reliable parking all influence average daily rate and occupancy. In a compact beach town, these details can move the needle on returns.
Operations that shape returns
Understand the difference between occupancy and capacity. Occupancy is the percentage of nights booked each year. Capacity is the maximum number of guests allowed per booking. Capacity is a compliance factor, and occupancy drives revenue, so both matter.
Minimum stays shape the work. Longer minimums reduce turnovers and cleaning frequency, while shorter minimums can increase bookings and cleaning costs. Platform calendars and guest messaging help you control turnover on high-demand weeks.
Plan for a local presence. Many coastal cities require a local contact or manager who can respond quickly to issues. Even if not required, a responsive local manager can protect your permit, your reputation, and your neighbors’ peace.
Secure the right insurance. STR use changes coverage needs and can void standard policies. Coastal properties often need specialized STR endorsements, wind and hail coverage, and sometimes flood insurance. Get quotes and confirm coverage types early in underwriting.
Account for parking and access. Limited on-site parking can affect guest satisfaction and occupancy. Proximity to public beach access and amenities can justify stronger rates.
Build your ROI model
A simple, honest pro forma is your best tool. Start with revenue, then layer in costs, then analyze returns and risk. Use conservative assumptions for winter and realistic peak rates for summer.
Key inputs to gather
- Purchase price and closing costs.
- Renovation and furnishing budget to meet guest expectations.
- Seasonal average daily rate by month, if possible.
- Occupancy rate by season or a blended annual rate.
- Cleaning fees, pet fees, and other ancillary income and who keeps them.
- Platform or host fees and any booking fees.
- Management fee percentage if using a property manager.
- Operating costs: property taxes, insurance, utilities, HOA, maintenance, linens and laundry, supplies, licenses and permits, marketing, accounting, and reserves.
- State and local accommodations or sales taxes and how they are remitted.
- Loan amount, rate, amortization, and annual debt service.
Step-by-step math
- Gross Rental Revenue = ADR × Occupied Nights.
- Effective Gross Revenue = Gross Rental Revenue + Cleaning Fees + Ancillary Revenue − Platform Fees.
- Operating Expenses = total yearly non-debt expenses, including management.
- Net Operating Income (NOI) = Effective Gross Revenue − Operating Expenses.
- Cap Rate = NOI ÷ Purchase Price.
- Cash Flow Before Taxes = NOI − Annual Debt Service.
- Cash-on-Cash Return = Cash Flow Before Taxes ÷ Cash Invested.
- Debt Service Coverage Ratio (DSCR) = NOI ÷ Annual Debt Service. Lenders often look for 1.2 to 1.35 or higher.
Hypothetical example
The numbers below are for illustration only to show how the math works.
- ADR: 300 dollars
- Occupancy: 40 percent, or 146 nights
- Cleaning fees collected: 3,000 dollars
- Platform fees: 3 percent of gross rental revenue
- Management fee: 25 percent of rental revenue
- Operating expenses: 20,000 dollars per year (taxes, insurance, utilities, maintenance, HOA, permits)
- Purchase price: 800,000 dollars
- Down payment: 25 percent, or 200,000 dollars
- Loan: 600,000 dollars
- Annual mortgage payments: 40,000 dollars
Calculations:
- Gross Rental Revenue = 300 × 146 = 43,800 dollars
- Effective Gross Revenue = 43,800 + 3,000 − 1,314 = 45,486 dollars
- Management fee = 25 percent × 43,800 = 10,950 dollars
- Operating expenses total = 20,000 + 10,950 = 30,950 dollars
- NOI = 45,486 − 30,950 = 14,536 dollars
- Cash Flow Before Taxes = 14,536 − 40,000 = −25,464 dollars
- Cap Rate = 14,536 ÷ 800,000 = 1.82 percent
- Cash-on-Cash = −25,464 ÷ 200,000 = −12.7 percent
Interpreting the example
This simple hypothetical shows how sensitive returns are to ADR, occupancy, management fees, and insurance and tax costs. Your underwriting should model conservative, base, and upside cases. A month-by-month cash flow is best, since off-season months can be lean and hurricane season can add surprises.
Stress test and plan for coastal risks
Run multiple scenarios. Use low ADR and occupancy for conservative cases, market rates for base cases, and higher ADR and occupancy for upside. Check your DSCR in slow months and your yearly average.
Budget for higher insurance and storm costs. Coastal wind, hail, and flood coverage can be expensive and deductibles can be high. Set aside a contingency fund for closures, repairs, and deductibles.
Keep an eye on policy changes. New local rules can cap nights or change permit categories. Neighbor complaints can trigger fines or suspensions. Build compliance and good neighbor policies into your operations.
Check lender rules. Some lenders treat STR-heavy properties differently, which can affect rate, down payment, and underwriting. Work with a lender familiar with STRs.
Your underwriting checklist
Use this checklist to organize due diligence before you write an offer or convert a property.
Verify eligibility and compliance
- Confirm City of Folly Beach STR permits, inspections, occupancy, parking, and operational rules.
- Verify zoning and any HOA or condo restrictions for the exact address.
- Determine if a local contact or management agent is required.
Market homework
- Pull live comps on major STR platforms. Record ADRs, minimum nights, cleaning fees, and calendar availability.
- Use market intelligence tools for seasonality and occupancy trends.
- Speak with local STR managers to validate realistic occupancy and cost drivers.
Financial homework
- Build a 24-month, month-by-month pro forma that reflects seasonality.
- Stress test with lower occupancy and higher operating costs.
- Get insurance quotes for STR coverage, wind and hail, and flood before finalizing assumptions.
- Confirm state and county tax registration and remittance steps.
Operational risk management
- Set clear house rules: max occupancy, quiet hours, and no parties.
- Establish a local response plan for guest issues and neighbor concerns.
- Reserve 5 to 10 percent of gross revenue for capital repairs and storm impacts.
- Evaluate professional management and its impact on NOI.
When to consider professional management
Professional STR management can be valuable in a coastal, seasonal market. Typical fees range from 15 to 35 percent depending on services. A good manager can optimize pricing by season, handle compliance and inspections, coordinate cleanings and maintenance, and respond to issues quickly. Compare fee impact to improved occupancy, higher ADR, and fewer headaches.
