Operating Expense Ratio

Operating Expense Ratio: a practical Canadian real estate investor guide to definition, deal math, underwriting use, common traps, and Realist.ca implementation.

Definition

Operating expense ratio is operating expenses divided by effective gross income. It shows how much revenue the building consumes before debt.

Example

In underwriting, tag operating expense ratio beside the exact source input and rerun the model when that input changes. The point is not a pretty metric; it is a better buy, hold, refinance, or walk decision.

Why It Matters

operating expense ratio changes what a disciplined buyer can pay, how much debt the asset can safely carry, and whether the return is coming from operations or fragile assumptions.

Investor Interpretation

Use it to kill bad deals quickly. If the back-of-envelope version does not survive conservative assumptions, do not spend five hours making it look alive.

Realist Tie-In

Realist.ca can make operating expense ratio searchable as an encyclopedia entry, link it to property underwriting, and show it beside listings, saved analyses, market pages, and investor lead magnets.
