  description

  STRunderground analyzes any Zillow listing as a short-term rental investment (ex. Airbnb, VRBO), without leaving the page.
                                                                                               
  Browse Zillow normally. When you land on a property listing, click "Analyze as STR" and get a full deal breakdown in seconds:
  
  • AI Deal Score (1-10) with an honest verdict: strengths, concerns, and a recommendation
  • Real Airbnb comp data: average daily rate, occupancy, and revenue from actual nearby listings
  • Full deal calculator: cash-on-cash return, monthly cash flow, cap rate, DSCR, and total ROI
  • Regulatory check: know if STRs are restricted or require permits in that city
  
  No more copying URLs between tabs. No more building spreadsheets. No more guessing.
  
  How it works:
  
  1. Navigate to any Zillow property listing
  2. Click the "Analyze as STR" button that appears
  3. Get your full analysis in ~15 seconds
  4. Save properties to your pipeline or open the full breakdown on
  strunderground.com
  
  Free users get 3 analyses/month. Pro ($19/mo) and Max ($39/mo) plans available at strunderground.com.
