Cap rate is one of the first numbers any owner hears when they start thinking about selling, and it's also one of the most misunderstood. It's not a single citywide figure. It moves by property type, by neighborhood, and by market conditions, and it directly sets what your income-producing property is worth.
A quick refresher
Capitalization rate (cap rate) is net operating income (NOI) divided by property value, expressed as a percentage. Flip the formula around and it becomes a valuation tool: value equals NOI divided by the market cap rate. Multifamily, office, retail, and industrial properties are typically valued this way, which is why "how to value a multifamily property" so often comes back to finding the right cap rate.
Why cap rates differ by property type
Buyers price risk and growth expectations into a cap rate. Stabilized multifamily buildings in strong neighborhoods tend to trade at lower cap rates (higher prices per dollar of income) because that income is seen as dependable. Office and certain retail assets, facing more uncertain demand, often trade at higher cap rates. The specific numbers move with the market, but the ranking, and the reasons behind it, tend to hold.
Why cap rates differ by neighborhood
The same property type can trade at very different cap rates in different submarkets, reflecting differences in rent growth expectations, tenant demand, and how much competing supply is nearby. This is why "average cap rate by city" numbers are only a starting point. What matters for your building is the cap rate for your specific property type in your specific neighborhood.
What rising cap rates mean for your income value
Cap rates and property values move in opposite directions. When cap rates rise (often alongside rising interest rates or softer demand), the value of a given income stream falls, since buyers now require a higher return for the same NOI. This is exactly the environment where a property's land value can pull ahead of its income value, since zoning-based value isn't driven by the same interest-rate-sensitive math.
Where land value comes in
If your building's income value has been squeezed by a rising cap rate environment, it's worth checking whether your land value has held up better, particularly if you're sitting on an under-built lot. That comparison, income value against land value, is often the difference between an owner who feels stuck and an owner who realizes they have a strong sale on their hands.
