Short answer: There is no single right number, but many analysts treat roughly 5% to 10% as a normal range. FirstDoor flags 6% or higher as healthy for a first rental because it leaves more room for financing costs and surprises.
What cap rate tells you
Cap rate is the yearly return a property would earn if you paid all cash. It ignores your mortgage, which makes it a clean way to compare one building with another.
Cap rate = annual NOI ÷ purchase priceNOI (net operating income) is rent minus operating costs: taxes, insurance, HOA, vacancy, maintenance and management. Not the mortgage. See the glossary if that's new.
What range is "good"?
There's no universal number. Investopedia notes that many analysts consider roughly 5% to 10% a reasonable range, and that higher cap rates generally come with higher risk while lower ones mean lower returns but lower risk. Location, property condition and your goals all move the target.
For a first rental, FirstDoor treats 6% or higher as a healthy sign, because it usually leaves room for financing costs and surprises. It's a beginner rule of thumb, not a law.
Tip: Compare cap rates within the same neighborhood and property type. A 5% in a prime area and a 9% across town aren't the same kind of deal.
Why price changes everything
The same income is a better or worse deal depending on what you pay. Here's the example property's NOI of $13,824/yr at different prices:
| Price $150,000 | 9.2% |
| Price $180,000 | 7.7% |
| Price $220,000 | 6.3% |
| Price $260,000 | 5.3% |
That's why negotiating price is often the fastest way to fix a weak cap rate.
Cap rate traps
Red flag: A listing's "cap rate" that leaves out vacancy, maintenance or management. Recalculate it yourself with realistic expenses.
A very high cap rate can mean a rough area, deferred repairs or rents that won't last. And because cap rate ignores financing, a good cap rate can still produce negative cash flow at today's rates. Always check cash-on-cash return and DSCR too.
Worked example
A $180,000 house renting for $1,800/mo, with $2,160/yr tax, $1,080/yr insurance, 5% vacancy, 8% maintenance and 8% management.
| Rent | $1,800 |
| Operating costs | −$648 |
| NOI per month | $1,152 |
| NOI per year | $13,824 |
Frequently asked questions
What is a good cap rate for a beginner?
There is no single right number, but many analysts treat roughly 5% to 10% as a normal range. FirstDoor flags 6% or higher as healthy for a first rental because it leaves more room for financing costs and surprises.
Does cap rate include the mortgage?
No. Cap rate uses net operating income, which excludes mortgage payments. That is why you also need cash flow, cash-on-cash return and DSCR.
Is a higher cap rate always better?
No. Higher cap rates often come with more risk, such as weaker locations, older buildings or less reliable rent.
