Key West and the Florida Keys represent the most supply-constrained and highest nightly rate short-term rental market in the entire state of Florida — a 120-mile island chain where the Overseas Highway connects a string of unique communities from Key Largo to Key West, where there is literally no buildable land remaining on most islands, where the combination of tropical climate, crystal-clear water, world-class fishing, diving, and a cultural identity built on Hemingway, sunset celebrations, and the southernmost point in the continental United States draws millions of visitors annually, where nightly STR rates routinely exceed $300–$800+ and ultra-premium properties command $1,000–$2,500+/night during peak season, and where the permanent scarcity of island real estate ensures that supply can never meaningfully expand — creating pricing power and appreciation dynamics that reward investors who acquire and hold.
Lendmire is a nationwide mortgage broker with access to the country’s top DSCR lenders. For Florida Keys investors, that means your specific deal — a Key West Old Town cottage, an Islamorada oceanfront villa, a Marathon fishing lodge, a Big Pine Key nature retreat, or a Key Largo dive-corridor condo — gets matched to the lender with the best program for your scenario.

What Is a DSCR Loan and How Does It Work in the Florida Keys?
A DSCR loan qualifies an investment property based on its rental income — not the borrower’s personal income, tax returns, or employment history. For a full breakdown, visit our complete guide on what is a DSCR loan.
The DSCR formula divides the property’s gross monthly rental income by its total monthly debt service — including principal, interest, taxes, insurance, and HOA fees. A ratio of 1.0 means the property breaks even. Above 1.0 means positive cash flow.
The Florida Keys’ DSCR profile is defined by premium nightly rates that are among the highest in the state. While acquisition prices are elevated — reflecting the permanent scarcity of island real estate — STR income of $300–$800+/night for standard properties and $1,000–$2,500+/night for ultra-premium waterfront homes produces annual revenue that supports DSCR qualification for investors who target the right islands, property types, and management strategies.

Why DSCR Loans Work for Florida Keys Investors
- No W-2s or tax returns required — out-of-state investors, self-employed buyers, seasonal residents converting to STR, and LLC borrowers qualify on property income alone
- LLC and entity ownership fully supported — essential for Keys investors managing high-value island properties with significant liability exposure
- Short-term rental income from Airbnb, VRBO, and luxury property management companies accepted in many programs. See our DSCR loans for Airbnb investments guide for details
- Closings in as few as 15 days via DSCR loans in 40 states with 15-day closing — move fast on the Keys’ extremely limited inventory where the best properties sell quickly
- Jumbo DSCR programs up to $6,000,000 — necessary for waterfront estates and premium Old Town Key West properties
- No state income tax — Florida’s tax advantage maximizes net return on the Keys’ premium STR income
- No limit on total financed properties — build a Keys portfolio across multiple islands without conventional caps
Florida Keys DSCR Investment Markets
Key West Old Town — The Crown Jewel of Florida STR
Key West’s Old Town is the cultural, historic, and economic heart of the Florida Keys — a walkable grid of Victorian and Caribbean-style cottages, guesthouses, and historic properties centered around Duval Street, the southernmost point in the continental U.S., Mallory Square’s nightly sunset celebration, and Hemingway’s home and museum. The density of bars, restaurants, galleries, and live music venues creates a nightlife and cultural tourism economy that operates 365 days a year.
Cottages and historic properties in the $700K–$2M+ range command STR rates of $350–$1,000+/night during peak season (December–April) and $200–$500/night during shoulder and summer months. Properties with pools, private parking (extremely scarce in Old Town), and walkable Duval Street proximity command the highest premiums. Key West’s year-round tourism season — unlike seasonal beach markets — produces consistent occupancy across all twelve months.
Important regulatory note: Key West has implemented strict STR regulations including a transient rental license requirement, occupancy limits, and zoning restrictions that vary by district. The city has periodically adjusted these regulations. Investors should verify current STR licensing availability and rules for their specific property location before closing.
New Town Key West / Stock Island — Value Alternative
New Town Key West and adjacent Stock Island offer more accessible entry points to the Key West market. New Town’s residential neighborhoods east of White Street provide proximity to Old Town attractions without Old Town acquisition prices. Stock Island’s working waterfront character, marinas, and the growing restaurant and arts scene around the Safe Harbor Marina have attracted a new wave of visitor interest.
Properties in the $500K–$900K range command STR rates of $200–$500/night. The lower acquisition prices relative to Old Town produce stronger rent-to-price ratios. For DSCR investors seeking Key West market exposure at more accessible price points, New Town and Stock Island deliver.
Islamorada — Sportfishing Capital of the World
Islamorada spans a chain of islands in the Upper Keys and has branded itself the Sportfishing Capital of the World — a designation earned by some of the best bonefishing, tarpon fishing, and offshore fishing in the Western Hemisphere. The village’s collection of waterfront resorts, tiki bars, and seafood restaurants along the Overseas Highway creates a laid-back tropical atmosphere that appeals to fishing enthusiasts, divers, and families seeking a Keys experience without Key West’s party energy.
Waterfront homes and villas in the $600K–$1.5M+ range command STR rates of $300–$800+/night. Properties with private docks, boat access, and canal frontage command significant premiums from the fishing tourism demographic. For DSCR investors targeting the Upper Keys’ most prestigious island community with deep sportfishing and luxury tourism demand, Islamorada delivers.
Marathon — Heart of the Keys and Family Tourism
Marathon sits at the geographic center of the Florida Keys and serves as the practical hub of the island chain. The city’s proximity to the iconic Seven Mile Bridge, Bahia Honda State Park (consistently rated one of the best beaches in the United States), the Turtle Hospital, and Sombrero Beach create family-friendly tourism demand that is broader and more accessible than Key West’s nightlife-driven visitor profile.
Properties in the $450K–$900K range command STR rates of $200–$500/night. Marathon’s more accessible price points relative to Key West and Islamorada produce stronger rent-to-price ratios. The family tourism demographic drives consistent occupancy during school vacation periods and holidays. For DSCR investors seeking the Keys’ most balanced combination of STR income, family appeal, and accessible acquisition prices, Marathon delivers.
Key Largo — Dive Capital and Upper Keys Gateway
Key Largo is the first island in the Florida Keys chain and the gateway to John Pennekamp Coral Reef State Park — the first undersea park in the United States and one of the most popular dive and snorkel destinations in the Western Hemisphere. The Christ of the Abyss underwater statue, glass-bottom boat tours, and the Florida Keys National Marine Sanctuary anchor a marine tourism economy that draws hundreds of thousands of visitors annually.
Properties in the $400K–$800K range command STR rates of $180–$450/night. Key Largo’s proximity to Miami (about an hour south) means it captures both dedicated Keys visitors and day-trip/weekend overflow from the Miami metro. For DSCR investors seeking Upper Keys STR at the corridor’s most accessible price points with the largest drive-to visitor base, Key Largo delivers.
Big Pine Key / Lower Keys — Nature Tourism and Seclusion
Big Pine Key and the surrounding Lower Keys (Sugarloaf Key, Cudjoe Key, Summerland Key) offer the Florida Keys’ most natural and secluded island experience. The National Key Deer Refuge on Big Pine Key, Bahia Honda State Park’s proximity, and the Lower Keys’ quieter character attract a visitor demographic seeking authentic island nature rather than resort amenities or nightlife.
Properties in the $400K–$750K range command STR rates of $180–$400/night. The Lower Keys’ limited commercial development and natural character create a different visitor experience than Key West or Islamorada — attracting nature photographers, kayakers, divers, and families seeking seclusion. For DSCR investors targeting the Keys’ most nature-focused STR niche at moderate acquisition prices, the Lower Keys deliver.
Short-Term Rental Investment in the Florida Keys
The Florida Keys’ STR market is driven by year-round tropical tourism, sportfishing, diving and snorkeling, sunset culture, and special events including Fantasy Fest, Hemingway Days, and fishing tournaments. Lendmire’s access to lenders offering specialized DSCR loans for Airbnb investments gives Keys STR investors financing that accepts Airbnb and VRBO income documentation.
Important regulatory note: STR regulations vary across the Florida Keys. Monroe County, the City of Key West, the Village of Islamorada, and the City of Marathon each maintain separate STR ordinances with different licensing requirements, occupancy limits, and operational rules. Key West in particular has implemented strict transient rental licensing with limited availability. Investors should verify current STR licensing and rules for their specific property location and municipality before closing.
Top Florida Keys short-term rental markets for DSCR investors:
- Key West Old Town — Year-round premium tourism STR with the highest nightly rates in the Keys. $350–$1,000+/night peak season
- Islamorada — Sportfishing and luxury waterfront STR. $300–$800+/night for dock-equipped properties
- Marathon — Family tourism and central Keys positioning. $200–$500/night with broad seasonal demand
- Key Largo — Dive tourism and Miami overflow weekend demand. $180–$450/night
- Big Pine Key / Lower Keys — Nature-focused seclusion STR. $180–$400/night
