Thinking about buying a beach-area home and renting it short term when you are not here? The numbers can work, but only if you underwrite the deal with clear eyes. In Manatee County, the right property, calendar fit, and compliance plan will make or break returns. In this guide, you’ll learn a practical, step-by-step way to estimate income, model expenses, evaluate rules, and plan for risk so you can compare opportunities with confidence. Let’s dive in.
What AMI means in this post
Locally, many people say “AMI” to mean Anna Maria Island. In this post, AMI means Average Monthly Income, or your projected gross short-term rental income. You will estimate AMI by season using comparable ADR (average daily rate) and realistic occupied nights per month. Then you will subtract expenses to see true cash flow.
Start with market and calendar fit
Your revenue lives and dies by the calendar. Manatee County’s coastal market has strong winter demand and softer summer and early fall. Break the year into at least two bands: a higher-demand season from around November through April and a shoulder or low season for the warmer months. Some properties justify three bands if your data supports it.
Think about what drives stays near your target home. Beach access and island amenities are big draws. Proximity to Sarasota’s cultural venues and airports matters. Local events, tournaments, and festivals can create short bursts of premium ADR. Check competing listings to see minimum night rules, rate strategies, and calendar gaps, and talk with local vacation rental managers for real booking trends.
To build AMI:
- Pull recent ADR and occupancy from true comparables, segmented by season.
- For each month: Projected gross = ADR x occupied nights (occupancy rate x nights in month).
- Build two cases: a conservative version and an optimistic version based on market averages and how well the property fits peak demand.
- Validate with recent booking calendars from comparable listings, not just asking rates.
Know the rules where the property sits
Manatee County contains multiple municipalities. Each city can have its own short-term rental rules in addition to county regulations, so you must confirm both county and city codes for the specific address. A home on Anna Maria Island may face a different set of rules than a home in unincorporated Manatee County or in the City of Bradenton.
What to verify before you buy:
- Registration and permits. Some jurisdictions require a short-term rental or business registration and an annual fee.
- Zoning and use. Confirm that short-term rentals are allowed in the zoning district. Some areas restrict or prohibit them.
- Operating rules. Check occupancy limits, minimum stays, parking standards, and noise or quiet hours.
- Safety features. Smoke and carbon monoxide detectors, egress, and fire extinguishers are typical requirements.
- HOA and deed restrictions. Community covenants can prohibit or limit short-term rentals even if the city or county allows them. Get the governing documents in hand.
- Taxes and remittance. Florida short-term rentals are subject to state sales tax and local transient or tourist development taxes. Hosts typically register and remit taxes to state and county authorities. Confirm current rates and processes with the Manatee County Tax Collector and the Florida Department of Revenue.
Rules can change. Municipalities in Florida update short-term rental policies from time to time, and enforcement can include fines or permit revocation. Always check current codes before you close.
Model expenses with care
Gross income is only the starting point. Short-term rentals have higher operating costs than long-term rentals, especially near the coast. Use line items that reflect how guests actually use the home.
Core operating expenses to include:
- Platform and payment fees. Account for the host side of platform and processing fees.
- Management fees. Full-service managers commonly charge 15 to 35 percent of gross revenue. Self-managing can reduce cost but increases your time commitment and need for local presence.
- Cleaning and turnover. Beach-area 2–4 bedroom homes often run about 100 to 300 dollars per turnover depending on size and amenities. Model expected turnover frequency to estimate a per-booked-night cleaning cost.
- Utilities. Electricity, water, cable or internet, and streaming services run higher than long-term rentals. Air conditioning use can spike in summer and storm season.
- Insurance. You will need homeowner or landlord coverage and, if applicable, wind or hurricane coverage and flood insurance. Coastal premiums can be materially higher and vary by carrier.
- Property taxes and licenses. Include property taxes, local surtaxes, licensing or registration fees, and tourist development taxes. Account for any tax you retain versus taxes you remit on guest charges.
- Supplies and services. Linens, consumables, small replacements, landscaping, pool service, and pest control.
- Maintenance and reserves. As a planning range, consider 5 to 10 percent of gross revenue for ongoing maintenance. Add a capital reserve of about 1 to 3 percent of property value per year for larger items like roof, HVAC, and appliances. Adjust for age and condition.
- HOA dues. Include HOA fees and any community facility costs.
Run your Net Operating Income (NOI) like this:
- Start with seasonal gross revenue (your AMI projections).
- Subtract platform fees, management, cleaning, utilities, insurance, property taxes, transient and sales taxes, HOA, maintenance, reserves, and marketing or other costs.
- The result is NOI. From NOI subtract debt service and income taxes to see cash flow.
Understand financing and taxes
Financing terms depend on how you will use the property and the lender’s program. Many traditional lenders treat short-term rentals as investments, not second homes. That affects loan-to-value, rate, reserves, and underwriting.
What to ask lenders:
- Will this be viewed as a second home or an investment property? Owner-occupied second-home loans typically require you to occupy the home for part of the year. Rules vary by lender.
- Does the lender use a debt service coverage ratio? Some specialty lenders use DSCR tests and may haircut your income assumptions.
- What pro forma will they accept? Expect conservative occupancy and ADR in underwriting.
Tax basics to keep on your radar:
- Rental income is taxable. You can typically deduct operating expenses, depreciation, mortgage interest, and some capital improvements. Talk with a tax advisor.
- Short versus long-term rental rules and personal use days can change how depreciation and passive loss rules apply.
- Sales and transient rental taxes are generally collected from guests and remitted to authorities. Failure to remit can create liabilities.
Plan for risk and exit options
Regulatory risk. Local governments may tighten short-term rental rules, especially in island or coastal neighborhoods with parking and noise concerns. A change in rules can reduce revenue or require conversion to a long-term rental.
Climate and insurance risk. Coastal Manatee County faces hurricane and flood exposure. If the home is in a Special Flood Hazard Area, flood insurance may be required for a mortgage and premiums can be significant. Florida has also seen insurance market volatility that affects availability and cost. Confirm insurability and quotes early.
Market risk. Travel trends, platform algorithm changes, economic cycles, or local oversupply can affect occupancy and ADR. Stress test your model with a softer season and lower ADR.
Exit flexibility. If you need to convert to a long-term rental, check local long-term rent levels and whether the layout makes sense for tenants. For resale, remember that STR-specific features can help attract investors, while neighborhoods that discourage STRs can reduce the investor buyer pool. Keep optionality in mind.
A simple underwriting workflow you can reuse
Use this checklist to compare listings side by side. A one-page summary for each candidate property keeps your decisions disciplined.
Market and calendar fit
- Identify your true comparables and document your data source and date.
- Set high and shoulder or low season ADRs and expected occupied nights per month.
- Note nearby demand drivers: beach access, event venues, sports facilities, airports, attractions.
- Record typical minimum stays and platform minimums for comps.
Regulatory and compliance
- Confirm jurisdiction: county and city. Check both codes for the exact address.
- Verify whether an STR permit or registration is required, fees, and processing time.
- Confirm zoning allows short-term rentals in that district.
- Pull HOA or deed covenants. Highlight any restrictions.
- List required safety features and any occupancy limits.
- List required tax registrations and current tax rates to remit.
Expenses and operating assumptions
- Build two AMI cases: conservative and optimistic.
- Estimate platform and payment fees, cleaning per turnover, and expected turnovers per month.
- Decide on management approach and fee percentage.
- Estimate utilities based on similar occupied properties.
- Gather insurance quotes, including wind or hurricane and flood if applicable.
- Enter property taxes and HOA dues.
- Set maintenance and capex reserve assumptions.
Financing and tax planning
- Choose your intended financing type: second home or investment loan.
- Note lender requirements, including DSCR and reserves.
- Capture tax considerations: personal use days and occupancy thresholds affecting depreciation.
- Estimate debt service and a preliminary cash-on-cash return under the conservative case.
Physical and hazard checks
- Confirm FEMA flood zone and elevation. Determine whether flood insurance is required.
- Check wind-borne debris region and hurricane vulnerability.
- Do a preliminary systems review: roof, HVAC, plumbing, and electrical.
- Confirm parking and access meet local rules and guest expectations.
Exit planning
- Define likely resale buyer pool and any neighborhood dynamics that affect investor interest.
- Assess feasibility of long-term conversion, including market rent estimates.
- Note any foreseeable regulatory changes or neighborhood pressures.
Local example: same county, different rules
A duplex in Holmes Beach may operate under rules that differ from a similar duplex in unincorporated Manatee County. Minimum stays, occupancy limits, and permitting can diverge across city lines. Always check the city code and the county code for the property’s legal address, and then confirm HOA covenants. This simple step can prevent a costly underwriting error.

FAQs
What does AMI mean in short-term rental underwriting?
- In this context, AMI means Average Monthly Income, your projected gross short-term rental income based on seasonal ADR and occupied nights per month. It is not Anna Maria Island, though the island is part of Manatee County’s market.
Are short-term rentals allowed everywhere in Manatee County?
- No. Manatee County includes municipalities with their own rules, permits, zoning, occupancy limits, and minimum stays. Confirm county and city codes for the specific address, and review HOA or deed restrictions before you buy.
How should I estimate cleaning and management costs?
- Full-service managers often charge 15 to 35 percent of gross revenue. For cleaning, beach-area 2–4 bedroom homes typically run about 100 to 300 dollars per turnover. Model your expected turnovers to estimate a per-booked-night cleaning cost.
What insurance do I need for a coastal short-term rental?
- Plan for homeowner or landlord coverage plus wind or hurricane and, if in a Special Flood Hazard Area, flood insurance. Coastal premiums can be materially higher and vary by carrier, so confirm insurability and quotes early in diligence.
How do I plan for the risk of rule changes?
- Underwrite a conservative case that still works if occupancy or ADR softens or if rules tighten. Have an exit plan to convert to a long-term rental or sell, and confirm that the property’s layout and neighborhood support those options.
