Miami Short-Term Rental Investment: How to Analyze an Airbnb Deal with DSCR Financing
The STR Opportunity in Miami
Miami sees over 25 million tourists annually. The city's year-round warm climate means there's no true off-season — just peak season (October–April) and shoulder season (May–September). Properties in the right locations can generate $4,000–$8,000/month in STR income versus $2,200–$3,200/month for long-term tenants.
That 2–3x multiplier is the reason sophisticated investors are building entire STR portfolios in Miami.
Miami Neighborhoods Where STR Works (Legally)
This is the critical filter most beginners skip. Miami-Dade has strict STR regulations, and many municipalities have banned or heavily restricted short-term rentals.
STR-Friendly Zones (as of 2026): - Unincorporated Miami-Dade: With license, STR allowed - Miami Beach (specific zones): Allowed with city license — check exact address - Brickell (certain condo buildings): Building must allow STR in their docs - Edgewater / Wynwood: Mixed — check zoning per address - Homestead area: Allowed — less competition, lower yields but lower prices
STR-Restricted (effectively banned): - Coral Gables - Pinecrest - Miami Shores - Most HOA-governed condo buildings
Before you analyze any deal for STR income, verify the legal status at that exact address. One wrong assumption destroys the entire investment thesis.
How to Analyze a Miami STR Deal
The analysis is similar to long-term rental but with different income numbers and higher expense ratios.
Revenue projection: - Annual occupancy rate for Miami STR: 65–75% (year-round market) - Average daily rate in Brickell: $180–$280/night - Monthly revenue estimate: $3,800–$6,500 depending on size and location
STR Expense ratio (higher than LTR): - Cleaning fees (pass to guest, but vacancy between stays affects occupancy) - Platform fees: 3% host fee on Airbnb - Supplies, linens, toiletries: $100–$200/month - Utilities (STR hosts typically pay): $200–$400/month - STR license: varies by municipality - Management (if outsourced): 20–30% of revenue
Rule of thumb for Miami STR: Use 55–60% expense ratio vs 40–45% for LTR.
Financing a Miami STR Property with a DSCR Loan
Most conventional lenders won't touch STR properties. DSCR lenders have caught up with the market.
In 2026, most DSCR lenders will: - Accept documented Airbnb/VRBO income history (12 months of statements) - Use 75% of average monthly STR income to calculate DSCR - Finance STR properties up to 75% LTV - Require the property to be in an STR-legal zone
The documentation requirement is the key difference: you need to show your Airbnb earning history, not just projected income.
For first-time STR investors who don't have Airbnb history on the property, some lenders will use a professional STR income analysis (available from companies like AirDNA) as a substitute.
STR vs LTR: When Does the Premium Justify the Work?
STR requires active management or a 20–30% management fee. Long-term rentals are passive by comparison. The STR premium only makes sense when:
- The legal zone allows it
- The price-to-rent ratio for LTR doesn't pencil (common in Brickell / Wynwood)
- You have systems in place (or a PM) to manage turnover
If the property would cash flow on LTR at the numbers you're buying at — that's your floor. Any STR upside is gravy, not the thesis.
