Cap Rate (Capitalization Rate)
A property's annual net income divided by its purchase price—a quick way to compare the earning power of different real estate investments. Higher cap rates mean higher potential returns, but usually more risk too.
Say you're looking at two rental properties and want a fast way to compare them. That's where cap rate comes in. You take the property's Net Operating Income (NOI)—the rent it brings in minus operating costs—and divide by the purchase price. A building generating $50,000 in annual NOI that costs $500,000 has a 10% cap rate.
Think of cap rate like the P/E ratio for stocks—it helps you gauge whether a property is fairly priced relative to what it earns. Lower cap rates usually mean pricier, more stable markets (investors accept thinner returns for safety). Higher cap rates signal cheaper markets or higher risk.
The numbers vary a lot depending on what and where you're buying. Prime urban office buildings might trade at 4-5% cap rates. Suburban apartments tend to land around 5-7%. Retail properties often sit at 6-9%, and rural or distressed properties can hit 8-12% or more.
One important catch: cap rate assumes you paid all cash—it ignores mortgage financing entirely. Your actual return with a loan will look different. It also doesn't capture appreciation, renovation upside, or tax benefits, so treat it as one useful lens rather than the whole picture.
If you invest in REITs, cap rates help you evaluate whether a trust is buying properties wisely. A REIT consistently acquiring at cap rates above its cost of capital is creating real value for shareholders.
Frequently Asked Questions
▸What's a good cap rate?
It depends on the property type, location, and market conditions. Generally, 5-10% is a common range. Lower cap rates (4-6%) are typical for prime locations with stable income. Higher cap rates (8-12%) may indicate higher risk or less desirable locations. Compare cap rates within the same property type and market.
▸Does cap rate include mortgage payments?
No. Cap rate is based on net operating income before debt service, assuming an all-cash purchase. It measures the property's return independent of how it's financed. Your actual cash-on-cash return with a mortgage will be different (potentially higher due to leverage).
