Most buyers start their Florida Keys home search online, but according to Sandy Tuttle, founder/owner of Island Welcome Real Estate, knowing which part of the Keys to focus on is more important than budget or bedrooms. The four main submarkets—the Lower Keys, Marathon, the Upper Keys, and Key West—offer different personalities, rules, and trade-offs.
Marathon stands out for investment-minded buyers because it is the only community in Monroe County that issues weekly vacation rental licenses to any home with no cap. “If someone is investment-minded and wants a better income return, we are absolutely going to suggest we explore Marathon,” Tuttle said. The trade-off is a more active environment with higher visitor turnover, which some buyers prefer and others avoid.
The Lower Keys, spanning from Big Pine Key to Key West’s edge, retain an old-Keys character with less traffic. Monroe County requires a 30-day minimum rental in most unincorporated areas, reducing constant turnover. “In the Lower Keys, you almost do not know which houses are rentals,” Tuttle said. Improved air access via Key West International Airport, with direct flights from multiple cities, makes the region accessible while maintaining a laid-back feel.
The Upper Keys, anchored by Key Largo, function as an extension of the Miami market, attracting day-trippers and weekend visitors. Proximity to Miami and Fort Lauderdale airports appeals to buyers wanting quick escapes, but higher density and traffic are drawbacks. Key West offers a vibrant mix with nightly and weekly rental licenses attached to properties, though no new licenses are issued, commanding premium prices for those with permits.
Tuttle advises buyers to consider daily lifestyle, boating needs, rental income goals, and long-term plans. “It is not one size fits all,” she said. “Things vary quite a bit, and we have to focus on a case-by-case basis to really identify properties.” Exploring the different communities across the Florida Keys is a useful first step before consulting a local expert.
