Introduction to Short-Term Rentals in Key West

Key West, the southernmost point of the continental United States, represents one of the most unique and lucrative—yet restrictive—short-term rental markets in the country. This tropical paradise, famous for its stunning sunsets, vibrant nightlife, and rich literary history, attracts millions of visitors annually seeking the ultimate Caribbean experience without leaving the U.S.

What makes Key West’s STR market truly exceptional is its extreme scarcity. Unlike most destinations where new short-term rental permits are available for purchase, Key West stopped issuing new transient licenses years ago and grandfathered only existing operations. This has created an incredibly exclusive market where transient licenses trade on the secondary market for $400,000 to $500,000 or more.

The result is a market that offers extraordinary returns for those lucky enough to own a transient-licensed property—with average revenue potential reaching $118,500 annually according to recent data—but creates nearly insurmountable barriers to entry for new investors. Key West’s approach represents one of the most aggressive STR limitation strategies in the United States, prioritizing housing preservation for locals over tourism expansion.

This comprehensive guide breaks down everything you need to know about Key West’s complex STR regulatory landscape, from the two-tiered licensing system to enforcement mechanisms and investment opportunities in 2025.

Advice from Successful Key West STR Operators

Insights from experienced Key West vacation rental professionals:

“The transient license premium is enormous, but the returns justify it if you buy the right property. Location is everything—Old Town proximity and unique character command the highest rates.” – Maria S., owner of 3 transient-licensed properties

“Enforcement is real and swift. We’ve seen neighbors call code enforcement on unlicensed operations, and those operators face serious consequences. Always verify license status before purchasing.” – Robert K., Key West property manager

“Monthly rentals are underestimated. We focus on snowbirds and remote workers who want to stay 1-3 months. It’s steady income without the operational intensity of nightly rentals.” – Jennifer P., non-transient rental specialist

“The Key West market rewards authenticity. Properties with genuine local character, historic significance, or unique amenities can charge premium rates that justify the high acquisition costs.” – David L., luxury vacation rental operator

“Insurance and maintenance costs are high here due to hurricane risk and salt air corrosion. Factor in 15-20% higher operating costs than mainland Florida properties.” – Amanda T., Key West real estate investor

The consensus among successful operators is that Key West’s extreme market restrictions create extraordinary opportunities for those who can navigate the barriers to entry, but requires sophisticated understanding of the local regulatory and economic landscape.
