What is Rental Arbitrage?

Lease a property long-term (e.g., 12 months), then sublet short-term (Airbnb/Vrbo/Booking) with the owner’s written consent. Profit = nightly revenue − (lease + utilities + cleaning + fees).

Key Benefits

  • Lower upfront costs vs. buying
  • Test markets with flexibility
  • High upside in tourist hubs

Key Risks

  • Lease violations if subletting is prohibited
  • Negative cash flow during slow periods
  • Fines for regulatory non-compliance

A–Z Guide

A — Assess Feasibility
  • Demand: Use AirDNA/Airbtics; winter peaks in South Florida; target high-tourism areas.
  • Landlord: Most leases prohibit subletting; negotiate a clear STR addendum.
  • Budget: Typical startup $5k–$15k for furnishings, deposits, and setup.
B — Business Planning
  • Form an LLC, set up banking, bookkeeping, and STR-specific insurance.
  • Target 20–30% net margin after all expenses.
C–F — Choose, Check, Contract, & Furnish
  • Choose Location: Favor STR-friendly zones (see “Where It Works”).
  • Due Diligence: Confirm city/county/HOA rules before signing.
  • Execute Lease: Written permission to sublet, plus STR addendum.
  • Furnish & Setup: Modern, durable furniture; smart lock; noise monitor; cameras (exterior only, disclose).
G–L — Get Licensed, List, Insure, Join, Taxes, Legal
  • Licenses: State DBPR (when applicable) + local permits (CU/Compliance/Business Tax).
  • Listings: Pro photos + dynamic pricing.
  • Insurance: Platform coverage ≠ replacement for STR policy.
  • Network: Local STR groups, cleaners, maintenance pros.
  • Taxes: Collect/remit FL 6% + local tourist taxes; track expenses.
  • Legal: Occupancy limits (e.g., 2/bedroom + 2); comply with safety/notice rules.
M–Z — Marketing → Zoning
  • Marketing: Sell the lifestyle—beaches, nightlife, events.
  • Noise Mgmt: Use monitors (e.g., required in parts of Broward).
  • Ops: Cleaners, automated check-in, SOPs.
  • Pricing: Seasonality; events; fees ≤20% of total.
  • Quality: Aim 4.8★+ for Superhost.
  • Risk: Screen guests; have emergency plans.
  • Scale: Validate unit economics before adding doors.
  • Track: ADR/Occ/RevPAR; adjust weekly.
  • Update: Winter premium pricing.
  • Vendors: Reliable, contracted cleaners.
  • Withdraw: Target $1k–$5k/mo per high-demand unit (after stabilizing).
  • Exit: Pivot to mid/long-term if STR underperforms.
  • Zoning: Verify every address before signing.

Tax Advantages for STR Investors (2025 Overview)

Provision What It Means Why STRs Benefit Practical Notes
100% Bonus Depreciation Immediate expensing of qualified personal property/improvements in Year 1. Combine with cost seg to create large paper losses early. Form 4562; consider opt-out strategy depending on income profile.
Section 179 Expense furniture/appliances/amenities up to the annual limit. Outfit new listings; pull deductions forward. Limited by taxable income; excess can carry forward.
SALT Cap Increase Higher cap can improve itemized deductions for state/local/property taxes. Helps in higher-tax jurisdictions. Applies on Schedule A; see current thresholds.
STR “Loophole” With average stays ≤7 days and material participation, losses may offset active income. Potential to offset W-2/business income without RE Pro status. Track hours (100+ per property or 500 total); maintain documentation.

Tax law is complex and evolving. Consult a CPA to confirm eligibility and filings for your situation.
