Quick Answer

Cap Rate Calculator estimates cap rate of 7.56% and net operating income (annual) of $26,450 for this scenario.

Key Takeaways

  • Cap Rate Calculator estimates cap rate of 7.56% and net operating income (annual) of $26,450 for this scenario.
  • Cap rate divides a property's net operating income by its price, so it measures income return before any mortgage. This scenario produces $26,450 of NOI ($2,204 per month) from $34,200 of effective rental income after vacancy.
  • It depends on the market and the risk, but many investors look for roughly 5–8% in stable areas and higher where rents are strong relative to prices. This scenario comes out at 7.56%. Very high cap rates usually signal higher risk or understated expenses rather than a free lunch.

How This Estimate Works

  • Cap rate divides a property's net operating income by its price, so it measures income return before any mortgage. This scenario produces $26,450 of NOI ($2,204 per month) from $34,200 of effective rental income after vacancy.
  • That makes the cap rate 7.56% — in the 6–8% range — solid income relative to price for many rental markets, provided the expense figures are complete.
  • Operating expenses total $7,750 per year, or about 22.7% of effective income. Cap-rate comparisons only work when every property counts expenses the same way, so check that taxes, insurance, maintenance, HOA, and management are all included.
  • At a 6% market cap rate, this income supports a value of about $440,833 — roughly $90,833 above the $350,000 price, which suggests the income justifies the price if the expense estimates hold.
  • Cap rate deliberately ignores financing: the same property shows the same cap rate whether you pay cash or borrow. Pair it with a debt-service check so a good cap rate does not hide a payment the rent cannot carry.

FAQ

What is a good cap rate for a rental property?

It depends on the market and the risk, but many investors look for roughly 5–8% in stable areas and higher where rents are strong relative to prices. This scenario comes out at 7.56%. Very high cap rates usually signal higher risk or understated expenses rather than a free lunch.

How is cap rate calculated?

Cap rate = net operating income ÷ property value. NOI is the rent after vacancy minus operating expenses (taxes, insurance, maintenance, HOA, management) — but before any mortgage payment. Here, $26,450 of NOI on the entered price gives 7.56%.

Does cap rate include the mortgage payment?

No. Cap rate is an unleveraged measure — it treats the property as if bought with cash. Your actual cash-on-cash return will differ once a loan is involved, which is why investors check cap rate alongside the debt service coverage ratio (DSCR).

What value does this income support at a 6% cap rate?

Divide NOI by the market cap rate: $26,450 ÷ 6% ≈ $440,833. If similar properties trade around a 6% cap, that is roughly the price this income justifies — pay more and you are betting on rent growth or appreciation.

Why did my cap rate come out negative or near zero?

That happens when operating expenses meet or exceed the rent after vacancy. Recheck that every expense is entered once and the rent is realistic — a near-zero cap rate means the property produces almost no income at its current price.
