Investment Property 101: What "Cap Rate" Actually Means
A plain-English walkthrough of the one number every investment buyer should know cold before making an offer.
If you've spent any time around investment buyers, you've heard the term "cap rate" thrown around like everyone already understands it. In practice, it's a simple ratio — but it's worth knowing exactly what it does and doesn't tell you before you rely on it to evaluate a deal.
The formula
Capitalization rate, or cap rate, is calculated as Net Operating Income divided by the property's current market value, expressed as a percentage. Net Operating Income is your annual rental income minus operating expenses — property taxes, insurance, maintenance, management fees — but before mortgage payments and depreciation. A property generating $60,000 in net operating income on a $1,000,000 purchase price has a 6% cap rate.
What it's useful for
Cap rate is a quick way to compare the income-producing potential of different properties, independent of how each is financed. It's a language investors use to talk to each other about value at a glance, and it's a reasonable first filter when you're screening a list of properties.
What it doesn't tell you
Cap rate says nothing about your actual cash flow after financing, nothing about appreciation potential, and nothing about the condition of the property or the quality of the tenant base. Two properties with identical cap rates can be very different investments once you factor in your specific loan terms, your down payment, and how much capital improvement the property actually needs.
A good cap rate makes a property worth a closer look. It's never the whole decision.
