Thinking about buying a vacation rental home in Key West? It can be an exciting move, but this is not a market where you want to make assumptions. Between transient rental rules, historic-property review, flood considerations, and sharp seasonal swings, the right purchase is usually the one that works on paper and in practice. This guide will help you understand what matters most before you buy, so you can move forward with more clarity and confidence. Let’s dive in.
Key West is not a plug-and-play vacation rental market. The local housing landscape is shaped by high land values, geographic and environmental limits, tourism demand, and controlled supply through local systems like ROGO and BPAS.
That matters because vacation-rental inventory is not easily replaced or expanded. In simple terms, lawful and usable rental properties can carry added value because new permanent and transient residential units face local constraints.
Key West also has a large concentration of historic wooden structures. If you are looking at homes in older parts of the city, preservation rules may affect renovation plans, timelines, and costs.
Vacation-rental performance in Key West is closely tied to tourism. Monroe County’s 2023 travel study says travel generated $172.9 million in local tax revenue, and accommodation and food services produced the largest direct earnings.
Demand is strong, but it is not flat throughout the year. The Florida Keys hotel forecast shows annual occupancy at 72.0% in 2024, with forecasts of 73.3% in 2025 and 74.2% in 2026.
Monthly occupancy can vary a lot. Late winter months can reach the high-80% range, while September 2025 is forecast at 51.5% and October 2025 at 61.1%.
If you are buying for income, annual averages only tell part of the story. A property that performs well in February may look very different in September once slower demand and fixed carrying costs are factored in.
That is why monthly cash-flow modeling matters in Key West. You want to test likely revenue against slower periods, not just peak-season expectations.
Many buyers are drawn to classic Key West homes, including frame vernacular houses, cigar maker’s cottages, eyebrow houses, Bahama houses, and bungalows. These homes can offer character and location appeal that fit the vacation-rental market well.
But older homes come with extra layers. Historic buildings are generally 50 years old or more, and improvements may trigger review by the Historic Architectural Review Commission, known as HARC.
That review process is not only about appearance. It supports preservation and conservation of historic districts and contributing buildings, which can affect what you can change and how you can do it.
Flood compliance can also become more important with older homes. The city notes that some buildings may be grandfathered at older elevations, but substantial improvement can trigger current elevation requirements.
Condos can be appealing because they may be easier to maintain than a detached home. Florida’s DBPR treats vacation condominiums, vacation houses, and apartments as examples of transient public lodging, so condos can be a lawful vacation-rental property type when properly licensed and approved.
Still, you cannot assume every condo is a fit for nightly or short stays. The intended use needs to match the licensing path, local tax receipts, and any applicable association rules.
Waterfront property has obvious appeal in Key West, but flood planning needs to be part of the buying decision from day one. The city maintains flood maps, and its elevation-certificate guidance notes that pre-1975 buildings may need an elevation certificate for insurance and lending.
Monroe County also warns that flooding can worsen during king tides and heavy rainfall. So when you evaluate a waterfront or low-lying property, you need to look beyond views and ask whether elevation, flood zone, and insurance costs still support your income goals.
A Key West vacation rental is not valued by bedroom count alone. Revenue is shaped by a handful of variables that can change the entire investment picture.
The most important point is this: the nightly rate is only the headline. Your actual return depends on what is left after taxes, insurance, upkeep, management, and any property-specific compliance work.
Florida’s Department of Revenue says transient rentals are subject to the state’s 6% sales tax, plus any applicable discretionary sales surtax. Monroe County’s current rate table also lists a 5% local option transient rental tax.
The Monroe County tax collector says owners remain responsible for remitting the local transient rental tax even when bookings come through platforms like Airbnb or VRBO. That means platform convenience does not remove your compliance burden.
For many buyers, this is where underwriting gets more realistic. You need to test gross income against taxes, insurance, maintenance, management, and possible historic or flood-related expenses.
Before you think about décor, pricing, or marketing, verify whether the property can actually be used the way you want. In Key West, this is the non-negotiable part of buying a vacation rental.
The City of Key West says all residential rental properties need a City of Key West Business Tax Receipt. The city separates rentals into two categories:
The city also says businesses operating within city limits need a Monroe County Business Tax Receipt. If you are buying with short stays in mind, both city and county requirements need to be checked before closing.
State licensing is another key layer. Florida DBPR says owners of new public lodging establishments and new owners of existing establishments must obtain a license before operating.
DBPR guidance specifically includes vacation condominiums, vacation houses, and apartments in the transient lodging category. So even if a property looks ideal for guests, that does not mean it is ready for lawful short-term rental use.
Some Key West transient medallion or transient-unit licenses may be transferable when a property is sold, but only through the city’s process and with applicable fees. That detail can have a major impact on value.
This is one reason existing lawful rental inventory often draws strong interest. With BPAS applying to all new permanent and transient residential units, the path to creating new supply is constrained.
If a listing is advertised as a vacation rental, do not rely on marketing language alone. The city specifically warns buyers to verify the validity of advertised vacation rentals because illegal rentals are often promoted online.
In Key West, the order of your research matters. If you start with finishes and projected rates before confirming lawful use, you can waste time on a property that does not fit your goals.
A practical due-diligence sequence looks like this:
This order helps you focus on the issues most likely to change the economics of the deal.
If you are buying a cottage or older home, pre-closing inspection and permit-history review are especially important. A charming property can come with deferred maintenance, unpermitted work, or renovation limits that are not obvious at first glance.
That does not mean older homes are a bad investment. It means you want a clear picture of what you are buying, what may need approval, and what kind of flood or elevation issues could affect future upgrades.
Vacation-rental purchases in Key West often cross multiple layers at once: real estate, licensing, historic review, flood planning, and investment analysis. If you are buying remotely or balancing lifestyle goals with income goals, local verification becomes even more important.
That is where a broker with Key West market experience can help you narrow the field, spot issues early, and evaluate properties based on how they actually function in this market. For many buyers, that can save both time and expensive missteps.
