If I had to teach this in one paragraph, I would start here: a cap rate is a yield shortcut, not a valuation model. Core idea: The capitalization rate divides net operating income by price. It tells you what unlevered yield you are buying, but it says nothing about growth, financing cost or exit assumptions. Why it matters: That matters because cap rates are the most common metric in real estate and also the most commonly overinterpreted. In real life: A 6% cap rate in a growing market with stable tenants is very different from a 6% cap rate on a building with deferred maintenance and lease rollover risk. Common slip: The mistake is comparing cap rates across markets and property types without normalizing for risk, growth and capital expenditure needs. Try this: If you had to teach this without jargon, what would you tell someone to monitor first? The point is not to memorize the label. The point is to know what variable is actually doing the work.
