Assumptions & methodology
  • Cavmir lift defaults: ADR +12%, occupancy +8 pp, direct-booking share lifts to 30% (cuts blended OTA fee drag). Conservative versus what we typically deliver.
  • Gross revenue: ADR × Occupancy × 365.
  • NOI: Gross revenue − operating costs (cleaning, mgmt, utilities, maintenance, lodging tax, property tax, insurance). Excludes debt service.
  • Annual cash flow: NOI − annual debt service.
  • Cap rate: NOI ÷ Purchase price.
  • Cash-on-cash: Annual cash flow ÷ (Down + Closing + Furnishings). Most calculators forget furnishings and overstate COC by 20-30%.
  • DSCR: NOI ÷ Annual debt service. Most lenders want > 1.20.
  • Breakeven occupancy: the occupancy at which annual cash flow = $0, all else held constant.
  • Methodology: we model with medians, not means. AirDNA-style mean forecasts skew high — that's a real-world trust issue we don't repeat.
