Cap rate (capitalization rate) is one of the most commonly used metrics in real estate investing. It tells you the annual return you can expect on a property based on its net operating income relative to the purchase price. But what counts as a "good" cap rate depends on the market, property type, and your investment goals.
How Cap Rate Is Calculated
The formula is straightforward:
Cap Rate = (Net Operating Income / Purchase Price) x 100
For example, a property with $15,000 in annual NOI and a $200,000 purchase price has a cap rate of 7.5%. RealixData calculates this automatically for every property analyzed, using estimated rent, vacancy rates, insurance, taxes, and maintenance costs.
Cap Rate Ranges by Market Type
Cap rates vary widely depending on location, risk profile, and property class:
- 3-5% cap rate — Typical in high-demand metros like San Francisco, New York, and Los Angeles. Lower risk, higher appreciation potential, but slim cash flow.
- 5-7% cap rate — Common in strong secondary markets like Tampa, Atlanta, and Charlotte. Balanced risk-return profile. This is where most buy-and-hold investors target.
- 7-10% cap rate — Found in tertiary markets and Midwest cities like Cleveland, Memphis, and Indianapolis. Higher cash flow but potentially slower appreciation.
- 10%+ cap rate — Often signals higher risk: vacancy issues, declining markets, or properties needing significant repairs. Requires thorough due diligence.
What Makes a "Good" Cap Rate in 2026?
For most residential rental investors, a cap rate between 5% and 8% is the sweet spot in 2026. This range typically means:
- The property generates meaningful cash flow after expenses
- The market has stable rental demand and job growth
- The risk-reward balance is favorable for long-term holds
However, a "good" cap rate alone does not make a good deal. A 10% cap rate in a market with 15% vacancy and declining population is worse than a 6% cap rate in a market with 3% vacancy and strong job growth. That is why RealixData's deal scoring algorithm weights cap rate at 20% but also factors in cash flow, 1% rule, price-to-rent ratio, market conditions, and property condition.
Cap Rate vs. Cash-on-Cash Return
Cap rate assumes you paid all cash. If you are using a mortgage (as most investors do), cash-on-cash return is a more accurate measure of your actual return. Cash-on-cash divides your annual pre-tax cash flow by your total cash invested (down payment + closing costs + rehab).
A property with a 6% cap rate might deliver 12% cash-on-cash return with favorable financing. RealixData calculates both metrics for every property so you can compare deals accurately.
Common Mistakes with Cap Rate
- Comparing cap rates across different markets — A 5% cap in Miami is not the same as a 5% cap in Memphis. Factor in appreciation, rent growth, and risk.
- Using listed rent instead of market rent — Cap rate should be based on realistic, achievable rent, not the optimistic number on a listing.
- Ignoring operating expenses — Taxes, insurance, vacancy, and maintenance vary significantly by location and property age.
- Chasing high cap rates — Above 10% usually means higher risk. Always investigate why the cap rate is elevated.
How to Use Cap Rate on RealixData
Every property analysis on RealixData includes an automatically calculated cap rate based on local market data. You can:
- Filter properties by minimum cap rate on the dashboard
- Sort the top deals page by cap rate to find the highest-yield properties
- Compare cap rates across markets using the best rental markets page
Understanding cap rate is essential, but it is just one piece of the puzzle. Use it alongside cash flow, the 1% rule, and the full deal score to make informed investment decisions.
