Underwriting Course

Master the Art of Underwriting Short-Term Rental Investments

FIBI’s CEO, Trevor Scelso, has been an active short-term rental (STR) investor for over five years and has worked in real estate finance and mortgage banking since 2018. He has personally purchased multiple high-performing vacation rentals with his own capital, as well as through joint ventures, syndications, and a real estate investment fund where he serves as Key Sponsor and Chief Investment Officer.

In this free short-term rental underwriting course, Trevor reveals the exact methods and formulas he uses to evaluate, acquire, and optimize profitable STR properties. These are the same techniques that have consistently produced cash-flowing assets in markets across the U.S.

What You’ll Learn

Inside this course, Trevor breaks down the step-by-step underwriting process that successful STR investors use to separate winners from losers before buying a property. You’ll learn how to:

  • Identify a property’s maximum profit potential using proven data-driven methods.
  • Estimate the material and design requirements needed to reach that potential.
  • Accurately calculate operating expenses and determine the resulting Net Operating Income (NOI).
  • Assess a property’s debt service coverage to understand how much leverage it can safely support.
  • Calculate ROI, cash-on-cash returns, and break-even occupancy to determine if the deal truly pencils out.

Instead of the all-too-common approach—“throw money at it and see what happens”—you’ll gain the clarity and confidence to make informed investment decisions before spending a dollar.

Why This Course Matters

Trevor’s underwriting system has helped countless investors avoid costly mistakes and identify the most profitable STR opportunities in any market. These methods not only reveal where the money is made—but also where it’s lost—empowering you to avoid high-risk properties and focus on those that deliver consistent, scalable income.

This course is raw, unfiltered, and practical—straight from the playbook of one of the industry’s most experienced STR operators.

Whether you’re a new investor looking to buy your first Airbnb or a seasoned operator wanting to improve your underwriting accuracy, this course will help you analyze short-term rentals like a professional and maximize your returns.
