A New Real Estate Investor’s Guide to Cap Rates

If you’re diving into the world of real estate investing, you may have heard the term cap rate. Understanding capitalization rates is one of the first steps toward evaluating whether an investment property makes financial sense.

This metric helps you compare properties, assess potential returns, and make better decisions about where to put your money.

In this guide, you'll learn what a cap rate is and how to calculate it. You'll also explore what makes a good cap rate, how it relates to your mortgage, and some limitations to keep in mind.

Cap Rate Definition

A cap rate, or capitalization rate, measures the expected annual return on a real estate investment based on the income the property generates.

It tells you what percentage of the property's value you can expect to earn back each year from rental income, excluding mortgage costs. Investors use cap rates to quickly compare different properties and gauge potential profitability.

How to Calculate Cap Rate

To calculate cap rate, you need two pieces of information: your net operating income and the property's current market value.

The cap rate formula divides your annual net operating income by the property's value, then multiplies by 100 to get a percentage. This percentage represents your potential return on the property before accounting for financing costs.

Here's the formula:

Cap Rate = (Net Operating Income / Current Market Value) * 100

Here’s an example so you can see how to calculate cap rate in action.

1. Determine the net operating income (NOI): Your NOI is your gross rental income minus operating expenses like insurance, property taxes, and maintenance. Mortgage payments are not included in this calculation. For example, if your property generates $36,000 in annual rent and costs $11,000 per year to operate, your NOI is $25,000.
2. Find the current market value or purchase price: You can use the price you paid for the property, a recent appraisal, or comparable sales in your area to determine the current market value. For this example, let's say the property's market value is $300,000.
3. Divide NOI by current market value: Take your $25,000 NOI and divide it by the $300,000 market value. This gives you 0.0833.
4. Multiply by 100: Multiply 0.0833 by 100 to convert it to a percentage. Your cap rate is 8.33%.

What to Know About Cap Rates and Mortgages

Cap rates and mortgage interest rates have an inverse relationship.

When interest rates are low, investors can borrow money cheaply, which often drives up property prices and pushes cap rates down. But when mortgage rates rise, property values tend to stabilize or decrease, and cap rates typically increase.

This is why capitalization rates help you time your purchases and evaluate whether securing a mortgage for an investment property makes sense in the current market.

Why Mortgages Are Excluded from Cap Rate Calculations

Mortgages aren't factored into cap rate calculations because this metric measures the property's performance independent of how you finance it. The idea is to compare properties on equal footing, regardless of whether you're paying cash or financing it with a loan.

It also introduces the concept of leverage. Positive leverage is when your cap rate exceeds your mortgage interest rate, and negative leverage is when your interest rate is higher than your cap rate. For a rental property, this relationship helps you assess whether borrowing money will increase or decrease your overall returns.

Understanding Positive Leverage in Cap Rates

Positive leverage means you're earning more from the property than you're paying in interest on your loan. For example, if your rental property has an 8% cap rate but your mortgage interest rate is only 5%, you're generating a 3% gain on borrowed money.

This advantage makes it easier to compare properties and determine which investments will give you better returns.

What Is a Good Cap Rate?

What one considers a good cap rate depends on the current interest rate environment and the type of property you're considering.

A 4% cap rate might be attractive in a low-interest-rate market where mortgage rates are around 3%, giving you positive leverage. But that same 4% cap rate becomes less appealing when mortgage rates climb to 6% or 7%, creating negative leverage that eats into your returns.

Factors That Influence Cap Rates

There are a few different factors that influence cap rates, including property location, asset class, growth potential, and more.

• Property location: Properties in stable, high-demand urban areas typically have lower cap rates because they're considered safer investments.
• Asset class: Single-family homes generally have lower cap rates than multi-unit buildings and commercial properties because they're easier to manage and sell.
• Market interest rates: Rising interest rates typically push cap rates higher as borrowing becomes more expensive.
• Economic trends: Strong job growth and rising wages tend to lower cap rates as more investors compete for properties, and economic downturns push cap rates higher.
• Property condition: Well-maintained properties often have lower cap rates because they need less immediate investment and attract reliable tenants more easily.
• Growth potential: Properties in developing neighborhoods usually have lower cap rates because investors accept smaller immediate returns in exchange for future appreciation.

Why Do Investors Use Cap Rates?

Cap rates give you a quick and standardized way to evaluate investment properties and make smarter decisions. You can use them for:

• Comparing similar investment opportunities: A property with a 7% cap rate is generating more income relative to its value than one with a 5% cap rate, making it easier to spot which investment offers better returns.
• Identifying potential risk levels: If you see a property with an unusually high cap rate compared to similar properties in the area, it's worth investigating what additional risks might be driving that number up.
• Tracking property performance: If your cap rate is declining because expenses are rising faster than rents, it signals that you may need to adjust your management strategy or consider selling.

Capitalization Rate Limitations

Cap rates are helpful, but they don't tell the full story about an investment property's potential. Here are some important limitations to keep in mind:

• They don’t include mortgages and leverage. Cap rates don't factor in financing costs, so if you're using a mortgage or considering investment property refinances, you'll need additional metrics to understand your true returns.
• They don’t account for future capital expenditures. Cap rates only reflect current operating expenses, not upcoming major costs like roof replacements or HVAC systems that could impact your returns.
• They’re snapshots in time. Your cap rate reflects a specific moment and doesn't account for future rent growth, vacancy changes, or shifting market conditions that will change your returns over time.

Final Thoughts: Capitalization Rate

Cap rates can be a powerful tool for evaluating investment properties, comparing opportunities, and assessing ROI. While they exclude financing costs, future expenses, and market changes, they can still serve as a solid starting point.

Ultimately, a strong cap rate is just one piece of the puzzle. You'll also want to secure financing that works in your favor. Ready to take the next step? Get prequalified today to see what you can afford and start building your investment portfolio with confidence.
