Key takeaways

  • Underwriting should explain the deal, not merely calculate a return metric.
  • Cost, rent, occupancy, expenses, financing, and exit assumptions all need to be reviewed together.
  • Memo-style output helps investors and lenders understand the risks behind the numbers.

What underwriting should clarify

A good underwriting model clarifies total project cost, financing needs, stabilized income, operating expenses, debt service, investor returns, and downside sensitivity.

Inputs that drive the deal

Land cost, hard cost, soft cost, rents, occupancy, expense ratio, leverage, interest rate, amortization, exit cap rate, and selling costs are all important drivers.

Why memo-style output matters

Investors and lenders need more than a spreadsheet result. A memo-style output helps explain the assumptions, risks, and investment recommendation in plain language.

How to use this in a real review

01

02

Translate rent, occupancy, expenses, and reserves into stabilized NOI.

03

Review debt capacity, exit sensitivity, and investment memo output before moving to committee discussion.

How to apply it

Practical review checklist

  • Build the project cost stack before relying on return outputs.
  • Test rent, vacancy, interest rate, and exit cap assumptions under downside cases.
  • Review DSCR and breakeven resilience before treating a deal as financeable.

Review risks

Common mistakes to avoid

  • Reviewing IRR before validating the cost stack and stabilized NOI.
  • Using one exit cap rate without testing downside value scenarios.
  • Ignoring debt coverage when the project looks attractive on unlevered return metrics.
