Thinking about buying an Islamorada vacation rental? It is easy to get swept up by the turquoise water, boating lifestyle, and strong visitor appeal. But if you are investing for income, the real question is not whether people want to visit Islamorada. It is whether a specific property can legally operate, carry its costs, and perform across a full year. This guide will help you evaluate the numbers, rules, and red flags before you move forward. Let’s dive in.
Islamorada sits in one of the most tourism-driven markets in Florida. Monroe County’s FY2025 Tourist Development Council report says visitors spent about $3.5 billion in the Florida Keys, generated almost $400 million in tax revenue, and supported more than 24,000 local jobs. The same report also noted a record 4.7 million domestic visitors in FY2025.
That demand matters if you are considering a short-term rental. The same county report says 16% of visitors stayed in short-term vacation rentals, while hotel average daily rate reached $348.03. It also reported that short-term vacation rental listings were up 36% since 2018, which means investor interest is rising, but so is competition.
A separate 2023 economic impact study adds more context. It found that about 2,336,400 visitors stayed in a hotel, motel, or short-term vacation rental, spent $406 per day on average, and stayed 3.5 days on average. For investors, that supports the big picture: Islamorada benefits from a visitor economy with meaningful and recurring travel demand.
Strong tourism does not automatically mean every listing is a great investment. In the Keys, performance can shift by season, property type, and submarket. A waterfront home with boat access may attract a different renter profile than a condo with more restrictive rules or fewer amenities.
Monroe County’s monthly lodging reports are helpful because they break out Islamorada as its own submarket. The June 2025 county summary showed hotel demand of 480.1K, ADR of $286.83, and RevPAR of $214.45. That same report said June 2025 hotel demand was up 9.1% year over year, ADR was down 4.5%, and RevPAR was up 2.0%.
The takeaway is simple: underwrite using full-year data and true local comps, not a peak-season snapshot. If a seller shares a strong winter revenue number without showing the slower months, you may end up projecting income too aggressively.
Before you analyze income, make sure the property is actually eligible for short-term use. In Islamorada, vacation rentals are allowed in certain single-family and multi-family residential categories for stays of 28 days or less, as long as code requirements are met. The village also requires annual registration.
That point cannot be skipped. A beautiful property with great nightly-rate potential may still be a poor investment if it does not qualify under the local rules or cannot satisfy licensing requirements.
You also need to confirm whether the parcel is inside the Village of Islamorada or in unincorporated Monroe County. The county has its own special vacation-rental program for eligible parcels, with a separate annual permit process. Jurisdiction matters because the rules, permitting path, and compliance steps can differ.
For 2026, the Village of Islamorada says vacation-rental applications and renewals are handled through its portal only. The listed license fee is $1,325, and the application requires a substantial set of documents and approvals.
Those requirements include:
Florida law also matters here. Under Chapter 509, a transient public lodging establishment includes property rented more than three times in a calendar year for periods of less than 30 consecutive days, or property advertised that way. That license must be in place before operation, and it must be renewed annually.
If you are an out-of-state buyer, the local manager requirement deserves extra attention. You want a clear operating plan in place before closing, not after.
Many investors focus on purchase price and nightly rate, then underestimate the tax burden on rental revenue. In Islamorada and Monroe County, the lodging tax stack is an underwriting item, not a minor line item.
Florida Department of Revenue materials show Monroe County at 5% local option transient rental tax. The state also lists Monroe County’s 1.5% discretionary sales surtax rate, and Florida law allows Monroe County to levy a high-tourism-impact tax as well.
The practical lesson is that you should review county and state requirements together before projecting net operating income. If you only model one tax and miss another required layer, your cash flow estimate may be off from day one.
This is one of the biggest issues in resort markets. Even if a property can qualify under state and village rules, the recorded property regime may still control whether it can be used as a vacation rental.
Islamorada’s application specifically requires a copy of any deed, subdivision, or condominium restriction that applies to the unit. That makes HOA and condo document review one of the first diligence steps, not one of the last.
Florida condominium law says amendments that prohibit rentals or change rental term length or frequency generally apply to owners who consent and to later buyers. Florida HOA law says post-2021 governing document amendments that prohibit or regulate rental agreements generally apply only to later buyers or consenting owners, though some amendments regulating rentals under 6 months and more than three times in a calendar year can apply more broadly.
For you as a buyer, the key point is straightforward: read the governing documents before you rely on income projections. A property’s legal use under local code does not guarantee that the association allows your intended rental strategy.
Islamorada and the Upper Keys operate within a broader growth-control framework. Monroe County says the Florida Keys are an Area of Critical State Concern, with carrying capacity tied to a 24-hour hurricane evacuation model. Its ROGO and NROGO systems use competitive permit allocation to guide growth toward infrastructure and away from velocity zones and environmentally sensitive areas.
For investors, that has two important implications. First, supply is constrained, which can support long-term scarcity. Second, replacement can be difficult, so location, compliance, and resilience matter even more than they might in a more flexible market.
This also means storm readiness is part of the investment story. You should treat flood, wind, insurance, maintenance, and hurricane-prep reserves as core operating costs.
When you review a vacation-rental opportunity, keep your process grounded in facts. Here is a practical checklist based on local requirements and market conditions.
Before you get excited about projected income, confirm:
Ask whether the property already has:
If these items are missing, your timeline and startup costs may look different than expected.
Next, look closely at operating practicality. Confirm:
A listing may look turnkey online but still need work to satisfy compliance requirements.
When estimating revenue, avoid the temptation to use only best-case months. Instead:
This last point matters because village criteria can change annually. For 2026 applications, the village lists $708,000 for RH/MU parcels and $1,062,000 for RC/RL/A parcels in assessed-value criteria on its application page. That is one more reason to avoid relying on old screenshots or outdated assumptions.
The best Islamorada vacation-rental investments usually check several boxes at once. They are not just attractive properties. They are properties with a clear legal path, realistic operating costs, and features that align with actual visitor demand.
In this market, smart investors tend to focus on:
That last point is especially relevant in the Florida Keys, where boating and waterfront access often shape buyer and guest interest. But no lifestyle feature should distract from the basics of compliance and underwriting.
Islamorada can be compelling for vacation-rental investors because it sits in a proven tourism economy with strong visitor spending, limited supply, and year-round appeal. But this is not a market where you can underwrite casually. Local code, licensing, taxes, property restrictions, and storm-related costs all play a major role in whether a listing works on paper and in practice.
If you are serious about buying in Islamorada, your edge comes from asking better questions before you close. A careful review of legal use, association rules, operating costs, and true submarket performance can help you avoid expensive surprises and identify the properties that actually fit your investment goals.
