Thinking about buying a vacation rental on Anna Maria Island but unsure how to judge the numbers? You are not alone. With strong tourist demand and very real coastal costs, getting ROI right takes a clear framework and local data. In this guide, you will learn a simple way to model returns, what to verify locally, and how to stress test your numbers before you buy. Let’s dive in.
Why Anna Maria demand matters
Anna Maria is a small barrier-island market with steady visitor interest from winter snowbirds, families, weekenders from Tampa Bay and Sarasota, and national leisure travelers. That demand supports whole-home and condo rentals with multi-night stays. Local events, spring break, and holiday weekends often lift rates and occupancy.
Seasonality is a big driver. Peak demand typically runs November through April. May and October act as shoulder months. Summer brings heat, humidity, and hurricane season, which usually softens occupancy and average daily rate. Your model should reflect at least three seasonal tiers rather than a single annual average.
Model by season, not averages
Averages hide reality. To build a credible revenue forecast for Anna Maria:
- Set three tiers: high, shoulder, and low season.
- Assign nights available, target occupancy, and ADR for each tier.
- Account for event spikes around holidays and spring break.
- Validate assumptions with market data from providers that track ADR and occupancy and with local property managers who can share booking patterns.
This approach helps you see how much your outcome depends on peak season, and how resilient your numbers are if summer underperforms.
Check rules before you buy
Anna Maria Island includes three municipalities: the City of Anna Maria, Holmes Beach, and Bradenton Beach. Each can have different short-term rental rules. Before you write an offer, confirm the following for the specific address:
- Is short-term renting allowed for the property type and zoning.
- Minimum stay rules, occupancy limits per bedroom, and parking requirements.
- Registration or permit steps, renewal timing, and fines for violations.
- Local noise, trash, and nuisance rules you must include in house rules.
- HOA or condo restrictions that may prohibit or limit short-term rentals.
Also confirm tax and licensing requirements. Florida imposes state sales tax on transient rentals, and Manatee County commonly adds a tourist development tax and possible local portions. Registration and remittance processes can change, so verify current rules with the Florida Department of Revenue and county offices. Use the Manatee County Property Appraiser for a property tax estimate and check FEMA flood maps to understand flood insurance needs.
Build your ROI pro forma
Start with a simple structure you can refine as you collect local data.
- Define availability and season tiers
- High season: November to April. Shoulder: May and October. Low: June to September.
- Set target occupancy and ADR for each tier based on local comps.
- Forecast revenue
- Rented nights = occupancy rate × nights available per tier.
- Gross rental income = sum of rented nights × ADR per tier.
- Estimate expenses
- Fixed annual costs: mortgage debt service (if financed), property taxes, insurance (hazard, wind, flood, liability), HOA or condo dues, management fee, utilities, licenses, and reserves for maintenance and capital items.
- Variable costs: cleanings per booking, consumables, booking platform fees, payment processing, and any compliance devices or safety equipment.
- Calculate key metrics
- ADR = total rental revenue divided by rented nights.
- Occupancy rate = rented nights divided by nights available.
- Net Operating Income (NOI) = gross rental income minus operating expenses (exclude debt service).
- Cap rate = NOI divided by purchase price.
- Cash flow before taxes = NOI minus annual debt service.
- Cash-on-Cash = cash flow before taxes divided by total cash invested.
- Break-even occupancy rate = (operating expenses + annual debt service) divided by ADR, then divided by 365.
- Validate and adjust
- Compare your ADR and occupancy to data from market analytics providers and local managers.
- Update utilities, insurance, and property taxes with real quotes and county records.
- Add a contingency reserve for repairs, storm impacts, or rule changes.
Example: a hypothetical deal
The numbers below are for illustration only. Use local, current data before making decisions.
- Purchase price: $900,000
- Down payment: 25% ($225,000). Loan: $675,000 at an assumed 6.0% interest, 30-year fixed
- Annual debt service: about $48,588
- ADR (annual average): $500
- Occupancy (annual average): 55% → about 201 rented nights
- Gross rental income: 201 × $500 = $100,500
Operating expense estimates (annual, hypothetical)
- Management fee (25%): $25,125
- Cleaning (assume 5-night average stay, about 40 bookings × $200): $8,000
- Utilities and internet: $6,000
- Property taxes (assume about 1.2% of value): $10,800
- Insurance (coastal, wind and flood): $8,000
- HOA or condo fees (if applicable): $6,000
- Maintenance and reserves (about 5% of gross): $5,025
- Total operating expenses: about $69,950
Results
- NOI: $100,500 − $69,950 = $30,550
- Cap rate: $30,550 ÷ $900,000 ≈ 3.4%
- Cash flow before taxes: $30,550 − $48,588 = −$18,038
- Cash-on-Cash: −$18,038 ÷ $225,000 ≈ −8.0%
Break-even
- Break-even nights = ($69,950 + $48,588) ÷ $500 ≈ 236 nights
- Break-even occupancy = 236 ÷ 365 ≈ 64.7%
Takeaway: At these assumptions, you would need a higher ADR, higher occupancy, a lower purchase price, or more favorable financing to achieve positive cash flow.
Run scenarios and break-even
Small changes in ADR and occupancy move the needle. Build three cases using your seasonal model:
- Conservative: lower ADR and occupancy, higher insurance and maintenance.
- Base: your best estimate from verified local comps.
- Optimistic: reasonable upside from renovations or professional revenue management.
In each case, record NOI, cash flow, cash-on-cash, and break-even occupancy. If your break-even rate is above what the market typically supports across seasons, the deal may be too tight.
Key cost drivers to watch
- Insurance: Coastal, wind, and flood coverage can be significant. Work with brokers who understand Manatee County coastal risk and mitigation credits.
- Property taxes: Use the Manatee County Property Appraiser to estimate current taxes and any special assessments.
- Management: Full-service vacation rental managers often charge 18% to 30% of gross booking revenue. Confirm exactly what is included.
- Cleaning and turns: Turnover costs vary with size and guest count. Your average length of stay affects how often you pay these.
- Maintenance and reserves: Budget 5% to 10% of gross revenue, higher for older or waterfront homes.
- Utilities and compliance: Internet, power, and water, plus any safety equipment or noise-monitoring tools required by local rules.
Ways to increase ROI
- Pricing and booking: Use dynamic pricing and professional revenue management to capture peak rates and improve shoulder season bookings.
- Occupancy mix: Target longer stays in shoulder months with weekly or monthly pricing aimed at snowbirds and remote workers.
- Property upgrades: Invest in amenities that lift ADR, such as quality linens, beach gear, outdoor spaces, and professional photography.
- Channel strategy: Use a mix of booking channels and build a repeat base with direct booking to reduce platform fees.
- Cost discipline: Explore hybrid management, energy-efficient upgrades, and hurricane mitigation that may reduce insurance premiums.
Risks and how to plan
- Regulatory change: Confirm legality for the specific address, keep permits current, and monitor city agendas. Have a plan for longer minimum stays or a pivot to midterm or long-term renting if rules change.
- Weather: Maintain adequate reserves, carry appropriate insurance, and document hurricane procedures and guest policies.
- Operations and reputation: Screen guests where allowed, standardize cleaning, and respond quickly to issues to protect reviews and reduce wear and tear.
- Market shifts: Track competing supply and visitor trends through local tourism data and your management team’s reporting.
Your local research checklist
- Market performance: Use a reputable data provider for Anna Maria ADR, occupancy, length of stay, and comps by bedroom count and property type.
- Manager insights: Ask local property managers for booking calendars, rate bands, and typical owner net outcomes for similar homes.
- Taxes and licensing: Confirm Florida transient rental tax requirements and Manatee County tourist development taxes and processes.
- Property taxes: Pull a current estimate from the Manatee County Property Appraiser.
- Flood and insurance: Check FEMA flood maps for the property and get quotes for wind, flood, and liability from coastal-focused brokers.
- City rules: Verify the specific STR ordinance and enforcement practices for City of Anna Maria, Holmes Beach, or Bradenton Beach, depending on the address.
