In this course you will:

  1. Learn about the real estate capital stack, and how debt is an important piece of any capital strategy
  2. Build a mortgage amortization table from scratch
  3. Review various Excel strategies for modeling debt service and loan payoff
  4. Take a look at the most common debt metrics and how to calculate each
  5. Learn to size a real estate loan based on DSCR, Debt Yield, and LTV
  6. Layer debt into development cash flows
  7. Learn techniques for calculating construction interest reserve
  8. Model the levered returns of a real estate investment


You are a member of A.CRE Advisors multifamily underwriting team. You and your team recently signed a letter of intent to purchase Foles Tower – a 300 unit, Class A, multifamily high rise in Center City, Anytown.

Thus far, you’ve put together some basic back-of-the-envelope analysis and run a 10-year discounted cash flow on an unlevered (before debt) basis. Your boss has now asked you to layer in debt to understand the risk and returns of the investment on a levered basis.

You have an investment committee meeting scheduled for the end of the week to seek approval to purchase Foles Tower and you’ll need this analysis completed before then. So you sit down with your boss to discuss how best to model the debt.
