The direct answer
There is no universal good cap rate. A cap rate is NOI divided by property value or price, so a useful benchmark must be interpreted against comparable assets, location, lease and operating risk, growth expectations, property condition and the NOI convention used.
Start with a consistent NOI
A cap rate is only comparable when the numerator is defined consistently. Confirm whether the NOI is trailing, forward-looking or stabilized, whether vacancy and management are included, and whether unusual income or expenses have been normalized. A seemingly attractive rate can be created by an overstated NOI rather than a genuinely better price.

Treat the market rate as context, not a pass-fail rule
Cap rates vary with asset quality, market conditions and perceived risk. A lower rate can accompany stronger expected growth or lower perceived risk, while a higher rate can reflect weaker demand, capital needs or uncertainty. Compare like with like and document the date and evidence behind any market benchmark.
Stress the assumptions before deciding
Recalculate the rate with lower rent, higher vacancy or normalized expenses, then review the dollar cash flow and financing separately. Cap rate ignores debt structure and does not measure the full multi-year return. It should be one lens in an underwriting process, not a standalone investment recommendation.
Worked example
A property priced at $500,000 with $35,000 NOI has a 7.0% cap rate. If normalized expenses reduce NOI to $30,000, the same price implies 6.0%. The one-point difference comes entirely from the operating assumption, illustrating why the NOI basis matters before comparing the result with a market benchmark.
Common mistakes and limitations
Do not label a fixed percentage as good for every property. A benchmark without a comparable market, asset type, date and consistent NOI basis can be misleading.
Cap rate depends on the quality and stabilization of the NOI assumption and does not by itself measure leveraged investor return.
Frequently asked questions
Is a higher cap rate always better?
No. It can indicate more income per dollar of price, but it can also reflect higher perceived risk, weaker growth or property-specific problems.
Does cap rate include the mortgage?
No. Cap rate is a property-level relationship based on NOI and value or price, before debt service.
