Cap Rate Basics

Understand capitalization rates and their role in commercial real estate

What is Cap Rate?

In the last lesson, you learned how to calculate Net Operating Income (NOI). Now let's discover what that NOI means for property value using the Capitalization Rate (Cap Rate), also known as the unlevered return.

The Basic Formula:

Cap Rate = NOI ÷ Property Price

This gives you the annual return percentage if you paid cash

Real Estate Example:

Property Price: $1,000,000 • Annual NOI: $80,000 • Cap Rate: 8.0%
Just like earning $80,000 per year on a $1,000,000 investment

Why Cap Rates Matter

1

Comparing Properties

“Should I buy Property A with a 6% cap rate or Property B with an 8% cap rate?” Cap rates let you compare different properties on equal footing.

2

Understanding Risk

Higher cap rates usually mean higher risk. A 10% cap rate might offer more money but with more risk, while a 5% cap rate may offer a more stable return.

3

Calculating Value

If you know the NOI and cap rate, you can find property value. This helps you determine if a property is priced fairly.

The Simple Formula

The cap rate formula is actually three formulas in one. You can rearrange it to find different pieces of information depending on what you know:

Finding the Return
Cap Rate =
NOI ÷ Price

“What return will I get?”

Finding the Price
Price =
NOI ÷ Cap Rate

“What should I pay?”

Finding the NOI
NOI =
Cap Rate × Price

“How much income do I need?”

Why “Unlevered” Return?

Cap rate is called the “unlevered return” because it excludes the effects of financing (leverage). It shows the return based purely on the property's performance, as if you paid 100% cash. This makes it perfect for comparing different properties regardless of how they're financed.

Continued Example

Let's continue with our Tuna's Tower Apartments from the NOI lesson. We calculated the NOI, now let's see what cap rate this property offers and what that means.

🏢 Tuna's Tower Apartments - Cap Rate Analysis

Property Details:
  • Purchase Price: $3,200,000
  • 20 units at $1,500/month each
  • 5.0% vacancy rate
  • Year 1 NOI: $231,460 (from NOI lesson)
Cap Rate Calculation:
Cap Rate = NOI ÷ Property Price
Cap Rate = $231,460 ÷ $3,200,000
Cap Rate = 7.2%
What Does 7.2% Mean?
  • • If you paid $3,200,000 cash, you'd earn 7.2% annually from NOI
  • • That's like earning $231,460 per year on your $3,200,000 investment
How Investors Make Money: NOI Growth = Value Growth

Cap rates are market metrics determined by what similar properties sell for in your area. As rents increase over time or expenses decrease, NOI grows. If the market cap rate stays the same (7.2%), the property value increases. This is how investors build wealth - by increasing income and controlling expenses, not by arbitrarily deciding what cap rate their property deserves.

Year 1:
$231,460 NOI ÷ 7.2% = $3,200,000 value
Year 2:
$238,404 NOI ÷ 7.2% = $3,296,000 value
Year 3:
$245,556 NOI ÷ 7.2% = $3,394,880 value
Value Growth: $194,880 over 3 years
This wealth building happens even if you never sell the property!

Key Insights

  • • Cap rate connects a property's NOI to its price, showing how much income you earn relative to what you pay
  • • It's an easy way for investors to understand how much money a property makes compared to its purchase price
  • • Beware of sellers using pro forma (projected) rates instead of actual current NOI
  • • Cap rates differ significantly across locations and property types - urban vs rural, office vs retail
  • • Higher cap rates indicate higher returns but potentially higher risk or lower quality assets

Reading the Market

Cap rates vary by property type, location, and market conditions.

Understanding Pro Forma vs. Actual Numbers

Sellers sometimes advertise cap rates based on projected income rather than actual income. A property listed as “6% cap rate” might actually be 3% based on current, actual rents.

Pro forma: Uses projected or market rents (what rents could be)
Actual: Uses current rent rolls (what rents actually are)
Best practice: Always verify actual rent rolls and operating statements
Tuna's Tower Apartments Analysis:

At 7.2%, Tuna's Tower Apartments falls in the “value-add or secondary market” range. This suggests it might be in a smaller city or need some improvements, but offers good income potential. Remember: this 7.2% cap rate comes from researching what similar 20-unit apartment buildings actually sold for in the same market, not from wishful thinking.

Key Takeaways

What You've Learned:

  • Cap Rate = NOI ÷ Property Price - This tells you the unlevered return (as if you paid cash)
  • Cap rates are “unlevered” returns - They exclude financing effects, showing pure property performance
  • Higher cap rates usually mean higher risk - A 10% property isn't always better than a 5% property
  • Cap rates help you compare properties - They put different properties on equal footing regardless of financing
  • Cap rates differ across locations and property types - Different markets and property types (office, retail, multifamily) trade at different cap rate ranges based on their risk profiles
  • You can rearrange the formula - Find cap rate, property value, or NOI depending on what you know
