A capitalization rate, or cap rate, is the percentage of a rental property's current market value that shows how much money it makes each year. This helps investors figure out how much money they could make.
A capitalization rate is a number that shows how much money a property can make compared to how much it costs. If you're looking at a rental property and want to know if the rent is worth the price, the cap rate will tell you in one simple percentage. This is one of the first things that experienced real estate investors look at before they get into any deal, and it's hard to find an experienced investor who doesn't do it.
The concept itself is straightforward. You take the property's annual net operating income and divide it by the property's current market value. According to CBRE, cap rates have historically served as a primary benchmark for commercial real estate valuation across every major property type. That formula works the same way whether you're looking at a four-unit rental building in Louisville or a 200-unit apartment complex in Dallas. The number you get tells you what percentage of the property's value it earns in income each year.
So, why should this be important to you? Cap rate cuts through a lot of the noise. No matter how you plan to buy the property, it doesn't matter. You can pay in full or put down 20%, and it doesn't matter. It only looks at the difference between how much money the building makes and how much it costs. You can easily put three or four properties next to each other and see which one gives you the most money for each dollar of value.
This is the part that people get mixed up about. The cap rate is a picture. It shows how much money you make in a year compared to the price right now. It doesn't say how much the property might make in five years, and it doesn't take into account big repairs or rising rents. It's a place to begin, not a place to end. You still have to do the work that comes with the number.
The formula is so simple that you can do it on the back of an envelope: Cap Rate = (Net Operating Income / Current Market Value) x 100. Three pieces of information and some division. But you should take a closer look at each part of that formula because if you get any one of them wrong, the whole calculation will be wrong.
Net operating income, or NOI, is the money left over after you collect rent and pay all the costs of running the building. According to the Federal Reserve Bank of St. Louis, real estate income metrics like NOI are essential for measuring the health of property investments at both the local and national level. You start with total rental income for the year. Then you subtract everything it costs to keep the property going: property taxes, insurance, maintenance, management fees, utilities if you're covering them, and a cushion for vacancies.
You can't take your mortgage away. It might not make sense, but there is a good reason for it. Your mortgage is affected by your credit score, down payment, and loan terms. The next buyer might pay for the deal in a way that is very different. The cap rate is meant to show how much money the property can make on its own, without considering how an investor buys it.
Once you have your NOI, divide it by the property's current value on the market. Not what the seller paid for it ten years ago or what the tax assessor says it's worth. You can find out the current market value by looking at recent sales or appraisals of similar properties in the area. This number will change as the market changes, so the same building can have different cap rates from year to year.
Some people who invest like to look at the purchase price instead of the market value. That's fine for looking at a deal you are about to make. When you compare properties in a market, though, market value keeps the comparison the same and gives you a more accurate number.
This just converts your decimal into a percentage so you can read it at a glance. If you divided and got 0.075, that gives you a 7.5% cap rate. Most investors get comfortable with this step quickly because the math is simple once you have the NOI and market value nailed down.
To make the math feel real, let's look at an example. You see a small apartment building with eight units, and each one rents for $1,100 a month. That means you make $8,800 a month in gross rental income, or $105,600 a year.
Now you need to take away your business costs. The average cost of property taxes is $8,400 per year. The cost of insurance is about $3,600. You are putting $6,000 aside for repairs and maintenance. Property management costs another $10,560, which is 10% of the total rents. And you're setting aside 7% of your budget for empty spaces, which comes to about $7,392 a year. Your total yearly costs are $35,952 when you add everything up.
If you take $35,952 away from $105,600, you get a net operating income of $69,648. That's the money the building gives you before you pay your mortgage.
The price of the building is $870,000. When you divide $69,648 by $870,000, you get 0.08005. You get a cap rate of about 8% when you multiply by 100. That means the building makes money equal to about 8% of its value every year.
Is that a good thing? It depends on what you want to do, the area, and how much other homes like yours are selling for in the area. In many markets, an 8% cap rate is a good number for a small multifamily property. Different investors will give you different answers because everyone has a different level of risk tolerance.
This is the question every new investor asks, and the honest answer is that it depends. According to the National Association of REALTORS®, cap rates vary widely by property type, location, and market cycle. A 5% cap rate on a Class A apartment building in a major metro area might be perfectly healthy, while a 5% cap rate on a run-down strip mall in a small town could signal that something is off.
This is a rough idea of what investors usually see in different types of properties. In strong markets, multifamily properties often sell for cap rates of 4% to 6%. The range for retail properties is 6% to 9%. Office buildings, which have been more unstable in the past few years, usually range from 6.5% to 8.5%. As the need for logistics space has grown, the prices of industrial and warehouse properties have dropped to between 5% and 7%.
A coworker of mine in Louisville was interested in a duplex that had a 9.2% cap rate. On paper, that looked great. But the building hadn't had a new roof in twenty years, and one of the units had been empty for months. The number by itself can't give you this kind of context. The high cap rate showed the risk, not a secret deal.
You can think of the cap rate as a temperature reading. It tells you something important, but you need more information to figure out what's going on under the number.
Cap rate isn't just a math exercise. Plenty of real-world forces push it higher or lower, and understanding those forces will help you get a better read on the number.
Properties in neighborhoods with high demand usually have lower cap rates. Why? Because investors are willing to pay more for a location that is safe and stable. Even if rents are high, that higher price lowers the cap rate. On the other hand, a house in a less desirable area might sell for less, which raises the cap rate. More risk means a better chance of making money. The trick is to see if the extra return is worth the extra risk, which means looking more closely at the neighborhood's path.
When interest rates rise, borrowing gets more expensive. That can cool demand from buyers, which puts downward pressure on property prices. At the same time, higher rates mean investors want a bigger return to justify the cost of capital, so cap rates tend to climb. According to JPMorgan, multifamily cap rates nationally held relatively steady between the final quarter of recent annual periods, even as interest rates remained elevated compared to historical lows. Broader economic health matters too. When GDP is growing and unemployment is low, investors will get more comfortable paying premium prices, and they'll accept lower cap rates.
A property that is well taken care of can charge higher rents, which raises NOI and can support a higher cap rate. On the other hand, properties that are well-kept cost more to buy, which can lower the cap rate. Older buildings that need repairs often sell for less, which raises the cap rate. But the money those buildings make might be less, and the chance of costly surprises goes up.
Long-term leases with reliable tenants make a property more predictable. That stability usually means a lower cap rate because the investment carries less risk. Short-term leases or vacant units add uncertainty, and buyers want a higher cap rate to make up for that. If you're evaluating a building where half the leases expire within the next year, that's going to have a very different risk profile than one where tenants are locked in for five or ten years.
When looking at an investment property, the cap rate is helpful, but it's not the only number you should look at. These are some other metrics that show you different sides of the same investment. Knowing how they all fit together can help you make a better choice.
Return on investment (ROI) is a way to figure out how much profit you made compared to how much you spent, including your financing. ROI changes based on how you set up the deal, unlike cap rate. Two investors who buy the same building but put down different amounts of money will get different returns on their investments. This is why ROI is a better measure of how well you are doing as an investor and cap rate is a better measure of how well the property is doing as an asset.
The internal rate of return (IRR) shows how much money a property could make while you own it. It takes into account things that cap rate doesn't, like rent increases, the money you'll make when you sell, and the time value of money. It's harder to figure out IRR, but it gives long-term investors a better idea of the whole picture.
The gross rent multiplier, or GRM, is even easier than the cap rate. You take the property's price and divide it by its gross annual rent, which does not include any costs. It's a quick way to check things out, but if you're not careful, it can give you the wrong idea because it doesn't include operating costs. A low GRM might look good at first, but then you find out that the property takes half of its income in taxes and maintenance. Most investors look at GRM first and then look at cap rate and IRR to get the full picture.
These metrics all have blind spots, which is why experienced investors usually look at all of them before making a choice. The cap rate tells you how much money the property makes. ROI and IRR show you how much money you made. GRM lets you read quickly. When you look at them all together, they give you a much clearer picture than just one number. The AmeriSave team can help you figure out how financing changes each of these calculations for the property you're thinking about.
Cap rate can be hard for even experienced investors to understand. I've heard of a few patterns from coworkers in operations at AmeriSave that can mess up your analysis if you're not careful.
One of the most common problems is using rent estimates that are too high. You might want to use what you think you could charge instead of what the building is currently charging. The cap rate should show how well things are going right now, not how well they could go. Keep the projections for your IRR study.
People also get confused when they don't think about vacancy and maintenance reserves. Your NOI looks better than it really is if you don't set aside money for the months a unit sits empty or the water heater that needs to be replaced. There is a good reason why a vacancy allowance of 5% to 10% of gross rents is standard. You need to learn how to budget for things that haven't happened yet, because they will happen eventually.
You might also go in the wrong direction if you compare cap rates across markets or types of property that are very different. A warehouse outside of Atlanta with a 6% cap rate and a small apartment building in Hawaii with a 6% cap rate are both measuring very different levels of risk. The number is the same, but the situations are very different, and the risks of each investment are almost nothing alike.
People also forget that cap rate doesn't include your debt, which is another thing that catches them off guard. If you're borrowing 80% of the money to buy something, your cash return will be very different from the cap rate. This isn't a problem with the formula. This is just a reminder that the cap rate is for the property, not your deal. If you get a loan from AmeriSave, the loan officer can help you understand how your debt structure affects the return picture.
After you find a property with a cap rate that works for your goals, the next step is to get financing. Loans for investment properties are not the same as the mortgage on your main home. Lenders usually want a bigger down payment, and the interest rates are usually higher because the risk is higher. Before you sign anything, make sure you know exactly how much it will cost you, because those financing costs will affect your actual return.
The AmeriSave team can help you figure out how to finance rental properties, such as through traditional investment property loans and other loan products that might work for you. It's a good idea to talk to someone who does this every day about the numbers because the loan structure you choose will affect your cash-on-cash return.
If you're an investor who is also looking for a new primary home, AmeriSave's prequalification process can help you figure out how much money you can spend on both properties before you start shopping. Knowing how much money you have to spend ahead of time saves you time and keeps you focused on deals that make sense for your budget.
You can quickly and easily figure out how much money a rental property makes compared to how much it costs using the cap rate. It's not perfect. It doesn't take into account how much rent will go up in the future, how much work needs to be done, or how your financing affects your return. It's hard to beat as a first filter for comparing investment properties, though.
Do the math. Take a close look at the NOI. Check out the neighborhood and the property itself to see if it is going up or down in value. Then, before you write a check, use cap rate with ROI, IRR, and GRM to get a full picture. AmeriSave can help you compare loan options and find one that fits your budget if you're ready to look into financing for an investment property.
The cap rate is the amount of money a property makes in net income each year as a percentage of its value. The cap rate is 8% if you buy a building for $500,000 and it makes $40,000 in net operating income. This is a quick way to find out if a rental property is making money.
No, cap rate only looks at the money that comes in and goes out of running a business. Your mortgage payment, which includes both the principal and the interest, is not included in the calculation. That's the plan. Without the mortgage, you can compare properties more fairly because each buyer pays for them in a different way. A loan officer can help you figure out how AmeriSave's mortgage rates might affect your cash flow on a specific deal.
Not all the time. A higher cap rate means more risk, but it can also mean higher returns. The property might be in a bad neighborhood, need expensive repairs, or have tenants who can't be trusted. A lower cap rate usually means the investment is safer and more stable, but it also has less room to grow. The right cap rate for you will depend on what you want from the investment and how much risk you're willing to take. You can use the guides in AmeriSave's Resource Center to help you choose between these choices.
Most investors want cap rates between 4% and 10%. However, what is "good" depends on the type of property, where it is, and what is going on in the market right now. A Class A apartment in a top metro market could sell for 4% to 5% and still be a good investment because it is stable. In a secondary market, a smaller building might need to reach 7% to 9% before it makes sense. Think about your options carefully. Use AmeriSave's prequalification tool to find out how much money you can spend before you start the process.
You can, but it doesn't happen very often. People mostly use cap rates for properties that make money because it's easy to see the difference between operating income and operating costs. For a single-family rental, the numbers can be so small that one empty unit or one big repair can change the cap rate. A lot of people who buy single-family rentals are more interested in cash-on-cash return or total ROI. A quick cap rate on a single-family rental can still help you figure out if the price is fair compared to the rent it gets. AmeriSave's ComeHome can help you find homes and connect your home search with your financing.
It costs more to borrow money when interest rates go up. People may not want to pay a lot for homes if they think they won't be able to sell them later. This lowers prices and raises cap rates. When interest rates go up, investors need a higher return to make the cost of borrowing money worth it. But the connection isn't always clear. In a strong market where rents are going up quickly, cap rates might not change even if interest rates do. AmeriSave keeps an eye on current mortgage rates so you can see how the current market might change the numbers behind your investment.
NOI covers all the costs of owning a property, such as property taxes, insurance, maintenance and repairs, property management fees, utilities that the owner pays, and a reserve for when the property is empty. It doesn't pay for mortgage payments, income taxes, or depreciation. One of the best things you can do to get an accurate cap rate is to make sure your expense estimates are realistic. If you're getting a loan to buy something, AmeriSave can help you figure out how the loan fits in with the other costs of running your business.
The cap rate shows you how much money a property makes based on its full value, not how much you paid for it. ROI tells you how much money you made on a deal based on how much you spent. The cap rate and ROI will be about the same if you pay in full. If you buy the property with a mortgage, though, your return on investment (ROI) could be much higher than the cap rate because you're making money on money you borrowed. Both of these numbers are important. The cap rate is like the property's grade, and the ROI is like your own report card. The AmeriSave Resource Center has articles and tools that can help you learn about both.
