Passive Income Through Short-Term Rentals: The Real Math

A well-bought STR can out-earn a long-term rental two to three times over. Here's the full picture — revenue, costs, and what it takes to run one.

How the cash flow actually works

  1. 1. Revenue: occupancy × rate, honestly modeled

    We underwrite from comparable listing data — seasonality, weekday gaps, and realistic occupancy, not the listing screenshot's best month.

  2. 2. Costs most first-timers miss

    Cleaning turnover, supplies, utilities, platform fees, permits, and a real maintenance reserve. Expect 35–50% of gross before debt service.

  3. 3. Management: self, co-host, or full service

    Full-service management costs 15–25% of revenue but makes the income genuinely passive. Self-managing pays you a second job's wage — decide which you're buying.

  4. 4. The tax layer

    For qualifying owners, cost segregation and bonus depreciation may affect a tax return. See the STR Tax Strategy guide for the mechanics.

Frequently Asked Questions

Is STR income really passive?

Only if you place professional management — and note that hurts the tax angle, which requires material participation. Most of our clients self-manage year one for the tax benefit, then transition.

What returns should I underwrite to?

We look for 8%+ cash-on-cash before tax benefits in today's rate environment, with the depreciation benefit treated as upside rather than the reason the deal works.
