Cudjoe Key Vacation Rentals: Investment Basics For Buyers

Picture yourself boating out to the reef in the morning and watching the sunset from your dock that night. If you are weighing a vacation-rental purchase on Cudjoe Key in 33042, that vision is within reach, but the numbers and rules matter. In this guide, you will learn the essentials: what to buy, how rentals perform, which permits and taxes apply, and how to underwrite returns the right way. Let’s dive in.

Why 33042 draws vacation renters

Cudjoe Key sits within easy reach of Lower Keys boating, diving, and the energy of Key West. Winter and spring snowbird travel provide strong demand, with peak season running roughly mid-December through April. Reports on the broader Keys show winter months and March often deliver the highest occupancy and average daily rates.

Proxy market snapshots for nearby Keys locations show ADRs in the several-hundred-dollars-per-night range and average occupancies often in the 40 to 50 percent range, with top performers above that. Waterfront homes with dockage and outdoor living tend to command premium ADR. Use a Cudjoe Key–specific data pull before you underwrite, and treat nearby Keys reports as reference points rather than gospel. For context on seasonality and regional travel momentum, see this Lower Keys recap from the area press in Key West Post. For a proxy market data snapshot, review this Duck Key performance report.

What to buy on Cudjoe Key

Common investment options include:

• Single-family waterfront homes with private dockage.
• Inland single-family homes.
• Units in gated resort communities, such as Venture Out Resort, which may have their own rental rules.
• Select condo or cluster-style properties.

Recent market snapshots show a high entry price in 33042. A late-2025 summary placed the median list price near the mid-seven figures, and many top-performing rentals are waterfront with dock access. Work with your agent to pull current MLS comps and rental histories so your offer reflects today’s pricing and the property’s income potential.

Permits and rules you must follow

Before you list a Keys home for short stays, confirm you can legally do so. In unincorporated Monroe County, most vacation rentals require a Special Vacation Rental Permit with an on-site inspection. The permit is annual and does not transfer when the home sells. Review the county’s core rules in the Monroe County vacation-rental code.

Monroe County also requires a Vacation Rental Manager License tied to a manager who lives and is licensed in the same section of the Keys (Upper, Middle, or Lower). That manager must be available 24/7 and respond to complaints within one hour. The county code also treats rentals under 28 days as a vacation-rental use and prohibits them in districts where tourist housing is not allowed. Zoning compliance is essential.

Practical steps you can take now:

• Confirm the parcel’s zoning and jurisdiction status with the county’s planning resources and applications portal on the Monroe County Forms & Applications page.
• Ask the seller for copies of the current Special Vacation Rental Permit, Vacation Rental Manager License, Monroe County Business Tax Receipt, Florida Department of Revenue sales-tax registration, and any applicable state lodging license. Verify they are in good standing per the county vacation-rental code.
• If the home is inside an HOA or gated community, obtain governing documents that address rental frequency, minimum stays, registration, and guest rules. Some communities regulate rentals in ways that affect permitting.

Taxes you must collect and file

Short-term stays in Monroe County are subject to the 5 percent Tourist Development Tax (TDT) on gross rental receipts for rentals of six months or less. This is in addition to State of Florida sales and use tax. The county warns that booking platforms may not remit the 5 percent local TDT for you, so confirm what your platform collects and what you must file directly. See the county’s guidance on the Monroe County TDT page.

Build taxes into your pricing and cash flow. If you collect taxes from guests and pass them through to the state and county, show those as separate line items in your pro forma.

State license and safety

Many Florida vacation rentals meet the state definition of a public lodging establishment and must hold a Florida DBPR Vacation Rental license through the Division of Hotels & Restaurants. Expect life-safety standards and, where applicable, DBPR inspections and balcony or railing documentation. Review forms and checklists on the DBPR Hotels & Restaurants page.

Waterfront, flood, and hurricane checks

Cudjoe Key is low-lying, with flood and hurricane exposure. Verify the property’s FEMA flood zone and obtain an elevation certificate. Flood status can affect insurance costs, renovation requirements, and resilience planning. Start with local planning resources on the Monroe County Forms & Applications page.

If the home has a dock, confirm permits and allowed uses. County rules limit guest watercraft and restrict chartering docks to non-guests. The Florida Keys National Marine Sanctuary also imposes anchoring and mooring restrictions around reefs and protected areas. Review the local rental and dock-use standards in the Monroe County vacation-rental code.

Hurricane season runs June through November. Plan for evacuation protocols, cancellation and refund terms, and a hurricane reserve. For background on evacuation clearance times and planning constraints in the Keys’ Area of Critical State Concern, see this regional planning overview.

Insurance and operating costs

Florida’s coastal insurance market has been volatile, and Monroe County sits among the higher-cost regions for homeowners coverage. Underwriters pay close attention to property age, roof condition, elevation, wind mitigation, and whether you allow short-term rentals. Obtain quotes early for wind, flood, property, liability with short-term rental endorsements, and loss-of-rental income coverage. For context on statewide dynamics, see recent market summaries in industry filings.

Underwrite returns with care

A simple framework helps you stay conservative:

1. Gather comps. Pull monthly ADR and occupancy for Cudjoe Key or the most comparable Lower Keys submarket from a data provider or a local manager. A proxy view is available in this Duck Key market snapshot.
2. Build monthly revenue. Use ADR times nights per month times occupancy, then sum 12 months.
3. Model guest taxes. The Monroe County TDT is 5 percent in addition to state sales tax. Decide whether to show taxes as pass-through or part of gross receipts. See the Monroe County TDT guidance.
4. Subtract operating costs. Include management (often 20 to 35 percent for full service in Florida STR markets), cleaning per turnover, utilities, HOA, routine maintenance, trash/landscaping, local business tax, insurance, property taxes, and a hurricane reserve.
5. Compute NOI and yields. Calculate cap rate, cash-on-cash, and DSCR if financed. Run optimistic, base, and conservative scenarios.

Quick example for a typical home

Here is a simplified, illustrative model based on recent market context for Cudjoe Key pricing and proxy Lower Keys performance:

• Purchase price: $1,449,000.
• Proxy ADR: $600 per night; proxy average occupancy: 45 percent.
• Estimated gross revenue: about $600 × 0.45 × 365 ≈ $98,550.
• Example combined guest taxes withheld and remitted: about 12.5 percent of gross, or roughly $12,319. Net after taxes collected and passed through ≈ $86,231.
• Operating costs vary. A 25 percent management fee would be around $24,000, plus cleaning and supplies near $8,000, with insurance, taxes, HOA, utilities, and maintenance often ranging $25,000 to $45,000 or more in the Keys. Depending on actual ADR, occupancy, and costs, NOI can be modest at this price point.

Takeaway: returns in 33042 often rely on premium pricing power from waterfront, dockage, and well-designed outdoor living, plus disciplined cost control. Always include a hurricane closure reserve.

Offer-ready due diligence checklist

• Confirm jurisdiction and zoning. Verify parcel records and zoning designation with Monroe County resources via the Forms & Applications portal.
• Verify permits and licenses. Request the seller’s Special Vacation Rental Permit, Vacation Rental Manager License, Business Tax Receipt, state tax registrations, and any DBPR public lodging license. Confirm there are no code-enforcement issues per the county code.
• HOA and community rules. Obtain governing documents and rental rules for any HOA or gated community and check enforcement history.
• Docks and shoreline. Confirm dock and seawall permits, permitted uses, and any sanctuary restrictions, using the county vacation-rental standards as a guide.
• Wastewater. Collect septic or system compliance documents if applicable, as required for vacation-rental permitting under county rules.
• Flood and elevation. Request an elevation certificate and pull FEMA map data for the parcel. Get early quotes for NFIP and private flood options via county resources on the Forms & Applications page.
• Insurance. Obtain quotes for property, wind, flood, liability with STR endorsements, and loss-of-rental income. Underwriters will ask about short-term rental use.
• Financials and host history. Request 12 to 24 months of rental revenue, monthly occupancy, platform payout reports, and cleaning and maintenance invoices. Verify who remits state and local taxes per the Monroe County TDT guidance.
• Contractors and resilience. Get bids for impact glass, roof work, and storm-prep upgrades.

Where local experts save you time

The fastest path to a compliant, profitable rental is a small local team:

• Monroe County planning and permitting staff to confirm zoning, permits, and timelines. See county application timelines on the Monroe County EM process page.
• A local short-term rental attorney for title, HOA, and code-enforcement exposure.
• A Monroe County–savvy insurance broker for wind and flood quotes and deductible planning.
• A licensed local vacation-rental manager who meets the county’s residency and response standards.
• A real estate agent experienced in Keys investments to source inventory, analyze comps, and guide inspections.
