Capitalization Rate (Cap Rate) is the most commonly used metric in real estate investing. It tells you what return you'd earn on a property if you paid all cash—a useful way to compare properties regardless of financing.

The formula is simple: Cap Rate = Net Operating Income (NOI) ÷ Property Value. If a property generates $24,000/year in NOI and is worth $300,000, the cap rate is 8% ($24,000 ÷ $300,000).

What's a good cap rate? It depends on the market and property class. Class A properties (new, prime locations) might have 4-5% cap rates. Class B properties typically run 6-8%. Class C properties (older, more management-intensive) might offer 9-12%. Higher cap rates generally indicate higher risk or more work.

Cap rates also vary by location. Major metros like San Francisco or NYC might see 3-4% cap rates, while smaller markets offer 8-10%. This doesn't mean smaller markets are "better"—appreciation potential and tenant quality differ.

Limitations of cap rate: it doesn't account for financing (your actual returns with a mortgage will differ), it's a snapshot in time (NOI can change), and it assumes current rent levels continue. Use cap rate to screen and compare properties, but dig deeper before making decisions.

While cap rate shows the property's performance, Cash-on-Cash Return shows YOUR performance as an investor. It accounts for financing—crucial since most investors use mortgages.

The formula: Cash-on-Cash Return = Annual Cash Flow ÷ Total Cash Invested. If you put $60,000 down (plus closing costs) and receive $6,000/year in cash flow after all expenses including mortgage, your cash-on-cash return is 10%.

This metric is powerful because it accounts for leverage. A property with 5% cap rate might deliver 12% cash-on-cash if you finance 75% of the purchase. Leverage amplifies your returns (and risks).

Target cash-on-cash returns vary, but many investors seek 8-12% in today's market. Returns below 8% may not justify the work of being a landlord. Returns above 15% often indicate higher risk or significant value-add opportunity (a fixer-upper, for example).

Important: Cash-on-cash only measures annual cash flow. It doesn't capture appreciation, principal paydown (equity building through mortgage payments), or tax benefits. A property with 6% cash-on-cash might still be excellent if it's appreciating 5%/year and you're building equity through loan paydown.

The 1% Rule is a quick screening tool used by real estate investors: a property's monthly rent should be at least 1% of the purchase price. A $200,000 property should rent for at least $2,000/month.

This rule helps quickly filter properties. In many markets, properties that meet the 1% rule will cash flow positively after expenses. Properties far below 1% (like 0.5%) typically won't cash flow and rely entirely on appreciation.

The 1% rule has become harder to achieve in appreciation-focused markets. In cities like San Francisco, Denver, or Austin, properties might rent for 0.4-0.6% of their value. Investors in these markets often accept negative or break-even cash flow, betting on appreciation.

Conversely, some Midwest and Southern markets offer 1.5-2% ratios. These properties cash flow well but may have slower appreciation, older housing stock, or more challenging tenant management.

Use the 1% rule as a first filter, not a final decision maker. A property at 0.9% with excellent appreciation potential and A+ tenants might outperform a 1.2% property with deferred maintenance and tenant turnover. Context matters.
