STR cash flow analysis: how to know whether a deal actually works
Why most STR projections are wrong
The revenue projections that listing agents, property managers, and online tools provide are almost always too optimistic. They cherry-pick peak-season months, ignore vacancy, undercount expenses, and assume occupancy rates that only the top 10% of operators achieve. An investor who underwrites based on these numbers will overpay for the property and underperform the model.
Accurate STR cash flow analysis starts with real comparable data from live bookings, not estimates or averages. BNB Accelerator underwrites every deal this way before it reaches a client.
The full expense stack most investors miss
Revenue is the easy number. A complete STR expense stack includes: mortgage payment, property management fee (20-25% of gross), cleaning costs per turnover, platform fees (3-5%), utilities, supplies, maintenance reserve (5% of gross), HOA fees, STR-specific insurance, and accounting. Miss any of these and the cash flow model is fiction.
BNB Accelerator's underwriting includes every line item, modeled against the specific property and market, before a deal is ever presented to a client.
Cash-on-cash return: the metric that matters
Cash-on-cash return measures annual net cash flow divided by total capital invested. In the markets where BNB Accelerator operates, professionally managed properties typically deliver 12-25% cash-on-cash returns. Every deal we present includes the projected cash-on-cash return with all assumptions visible and pressure-testable.
