A 5% cap rate on a $400,000 rental property means you’re collecting $20,000 a year in net operating income before financing. That one number tells you more about a deal’s risk profile and return potential than almost anything else on the listing sheet. According to CBRE’s H2 2025 Cap Rate Survey, cap rates across every major property type have stabilized after two years of expansion, and nearly three quarters of commercial investors plan to buy more assets in 2026 as pricing firms up (CBRE 2026 Investor Intentions Survey).
So yeah. Cap rate is kind of a big deal right.
But here’s what drives me crazy. I talk to investors every week who either don’t know what a cap rate actually measures, or worse, they use it wrong. They’ll compare a 4% cap rate to a 9% cap rate and assume the 9% is the better deal. That’s like comparing the price of a Honda to the price of a Ferrari and concluding Hondas are a better value because they’re cheaper. The number means nothing without context.
Lets fix that. I’m going to walk you through what cap rate actually is, how to calculate it yourself, what the current benchmarks look like in 2026, and (most importantly) how to actually use it when you’re analyzing deals. If you’re serious about real estate investing, this is one of those foundational concepts you’ll use on every single deal for the rest of your career.
What Is a Cap Rate?
Cap rate is short for capitalization rate. It measures the relationship between a property’s net operating income (NOI) and its value or purchase price. Think of it as the unlevered yield on a property. If you bought a property with all cash (no mortgage), the cap rate is roughly the annual return you’d earn from rental income.
The formula is dead simple:
Cap Rate = Net Operating Income / Property Value
Or if you want to go the other direction:
Property Value = NOI / Cap Rate
That second formula is actually how most commercial properties get priced. Appraisers and investors back into a value by dividing the NOI by whatever cap rate the market says is appropriate for that asset type and location. So when you hear someone say “cap rates compressed,” what they’re really saying is property values went up (assuming NOI stayed flat).
Philip Fisher wrote that the stock market is “filled with individuals who know the price of everything, but the value of nothing.” Real estate investors make the same mistake. Cap rate is one of the few tools that connects price to actual income, which is why it matters so much.
How to Calculate Cap Rate: Step by Step
Lets run through a real example. Say you’re looking at a small multifamily property listed at $500,000.
Step 1: Calculate Gross Rental Income
The property has 4 units renting for $1,200 each per month.
4 units x $1,200/month x 12 months = $57,600 gross annual rent
Step 2: Subtract Vacancy
No property stays 100% occupied forever. Use a realistic vacancy rate. I typically use 5-8% for well-located multifamily in strong markets. Lets use 7%.
$57,600 x 0.07 = $4,032 vacancy allowance
Effective Gross Income = $57,600 – $4,032 = $53,568
Step 3: Subtract Operating Expenses
This is where people mess up. Operating expenses include property taxes, insurance, property management, maintenance, utilities (if landlord-paid), and reserves for capital expenditures. They do NOT include mortgage payments. That’s important. Cap rate is a pre-financing metric.
For this example lets say operating expenses total $21,568 per year.
Step 4: Calculate NOI
Net Operating Income = $53,568 – $21,568 = $32,000
Step 5: Divide by Purchase Price
Cap Rate = $32,000 / $500,000 = 0.064 = 6.4%
That’s it. Not that hard right.
Now you have a number you can compare against other properties, against market benchmarks, and against your own return requirements. If you’re looking at a similar fourplex across town listed at $600,000 but generating $30,000 in NOI, that’s a 5.0% cap rate. Lower return for a higher price. Maybe the location justifies it, maybe it doesn’t. But now you can have that conversation with real numbers instead of gut feelings.
What Is a Good Cap Rate in 2026?
Ok so this is the question everybody asks. And the honest answer is: it depends entirely on the property type, the location, and your risk tolerance. But I can give you real benchmarks.
Premium/Core Markets (Austin, Nashville, Denver, Raleigh): 4-5.5%
These are the markets where institutional money is flowing. Cap rates are compressed because demand is high and perceived risk is low. You’re paying more per dollar of income, but you’re also getting appreciation potential and tenant quality. CBRE’s H2 2025 survey shows multifamily Class A assets nationally averaging 4.74%.
Secondary Markets (San Antonio, Knoxville, Boise): 5.5-7%
Better cash flow, slightly more risk. These markets might not have the same population growth trajectory as the Tier 1 cities but they often deliver stronger current income. A lot of my investor clients end up here because the math actually works for cash flow from day one.
Tertiary/Value-Add Markets: 7-10%+
Higher cap rates mean the market is pricing in more risk. Maybe the property needs work, maybe the tenant base is less stable, maybe the local economy is dependent on one employer. The returns look great on paper but you’re earning that premium through active management and accepting more downside.
Here’s what I tell people at Neuhaus Realty Group. There is no universally “good” cap rate. A 4.5% cap rate on a Class A multifamily in downtown Austin is a totally reasonable deal. A 4.5% cap rate on a Class C duplex in a small rural town would be insane. The cap rate needs to match the risk profile.
Cap Rates by Property Type: 2026 Benchmarks
This is where it gets interesting. Different property types trade at dramatically different cap rates because they carry different levels of risk and income stability. Here’s what the market looks like right now based on CBRE and industry data:
Industrial: 4.8-5.5%
Industrial has been the darling of commercial real estate for years and the cap rates reflect it. Strong tenant demand, long lease terms, low maintenance costs. CBRE projects 5 to 15 basis points of cap rate compression across most property types through 2026 (CBRE 2026 Outlook). If you can find industrial at a 6% cap rate today, you’re probably looking at a value-add deal worth investigating.
Multifamily: 4.7-5.8%
The range is wide here because multifamily covers everything from a garden-style apartment complex in a secondary market to a luxury high-rise downtown. Austin specifically is running around 5.5% on average, though Class A properties are tighter at 4.74%. The overbuilt conditions in Austin (vacancy near 14.5%) might actually create buying opportunities for investors who can ride out the absorption cycle.
Retail: 5.5-7.0%
Retail gets a bad rap but CBRE’s survey found that a plurality of professionals consider retail the most appropriately priced sector given risks and income growth potential. Net lease retail (NNN properties) with credit tenants like Dollar General or Walgreens trade at the tighter end. Strip centers with local tenants are at the wider end.
Office: 7.5-9.0%+
Office is the sector everyone is nervous about and the cap rates show it. Remote work uncertainty and rising vacancy have pushed cap rates higher. Class A office is around 8.4%, Class B at 8.68%. The spread between the best and worst office assets is wider than any other sector. That said, CBRE notes the spread has stopped widening for the first time since 2022, which suggests stabilization.
Single-Family Rentals: 4.5-7.0%
SFR cap rates vary massively by market. In Austin, Austin asking rents declined roughly 4% year-over-year through late 2025 (Rentometer 2025 SFR Report), which has pushed cap rates wider. In Sun Belt growth markets, you’re still seeing 5-6%. The challenge with SFR is that you’re buying one property at a time so there’s less diversification per dollar invested compared to multifamily.
Cap Rate vs. Cash-on-Cash Return vs. ROI
These three metrics confuse people constantly and I get why. They all measure “returns” but they measure different things. Here’s the quick version.
Cap rate ignores financing entirely. It tells you what the property yields if you paid all cash. It’s a property-level metric, not an investor-level metric. Use it to compare properties against each other and against market benchmarks.
Cash-on-cash return includes your mortgage payment. It measures the annual cash flow you actually receive divided by the actual cash you invested (down payment plus closing costs). This is the metric that tells you what YOUR money is earning after debt service.
Total ROI includes everything: cash flow, principal paydown, appreciation, and tax benefits. It’s the most comprehensive but also the hardest to calculate and the most dependent on assumptions.
So when do you use which?
Use cap rate when you’re screening deals and comparing properties. It strips out the financing variable so you’re comparing apples to apples. Two properties can have identical cap rates but wildly different cash-on-cash returns depending on how you finance them.
Use cash-on-cash when you’re making the actual investment decision. This is the number that tells you whether your down payment is working hard enough. I covered the full math on this in my cash-on-cash return guide.
Use total ROI for long-term hold analysis, especially for buy and hold strategies where appreciation and tax benefits are a huge part of the return.
What Drives Cap Rates Up and Down
Cap rates don’t exist in a vacuum. They’re driven by a handful of forces, and understanding these forces is what separates investors who time markets well from investors who just get lucky.
Interest Rates
This is the big one. When interest rates rise, cap rates tend to follow (eventually). The logic is straightforward. If a Treasury bond pays 4.5% risk-free, why would you accept a 4% cap rate on a rental property that requires management, maintenance, and carries vacancy risk? You wouldn’t. So cap rates adjust upward to maintain a reasonable spread over the risk-free rate. The Fed’s current rate sits at 3.5-3.75% with a median dot-plot projection of 3.4% by end of 2026 (FOMC March 2026 projections), which is supporting cap rate compression across most sectors.
Location
Gateway cities (NYC, SF, LA) trade at lower cap rates than secondary and tertiary markets. More demand for properties in those markets drives prices up relative to income. Austin has been moving from a secondary market toward a primary market over the last decade, and our cap rates have compressed accordingly.
Property Type and Tenant Quality
An Amazon distribution warehouse on a 15-year NNN lease with built-in rent escalations will trade at a much lower cap rate than a self-storage facility with month-to-month tenants. The more stable and predictable the income stream, the lower the cap rate.
Lease Term
Longer leases equal lower cap rates (all else being equal). A 10-year lease to a national credit tenant reduces your re-leasing risk to nearly zero for a decade. That certainty is valuable and buyers pay up for it.
Supply and Demand
When there’s more capital chasing deals than there are deals available, cap rates compress. When capital pulls back (like it did in 2023 after rate hikes), cap rates expand. Right now we’re seeing capital slowly return, which is putting mild downward pressure on cap rates.
Cap Rate Compression and Expansion: Understanding the Cycle
If you’ve been investing for more than a couple years you’ve lived through both. And if you understand the cycle, you can use it to your advantage.
2020-2022: Aggressive Compression. Near-zero interest rates, massive stimulus, institutional money flooding into real estate. Cap rates hit historic lows. A lot of people bought properties at 3.5-4% cap rates that, in hindsight, were priced for perfection.
2022-2024: Expansion. The Fed hiked rates aggressively. Borrowing costs doubled. Transaction volume cratered. Cap rates expanded 100-200+ basis points in some sectors (office got hit the hardest). Properties that traded at a 4% cap became available at 5-6%.
2025-2026: Stabilization and Early Compression. Morgan Stanley’s 2026 outlook projects a recovery in CRE fundamentals as rates come down. CBRE data shows cap rates holding steady in H2 2025 with 5-15 basis points of compression expected through 2026. Industrial is leading the compression, office is lagging.
Here’s the thing most people miss about these cycles. Gary Keller’s whole point in The Millionaire Real Estate Investor is that the best time to buy is when most people don’t want to. When cap rates are expanding and everyone is scared, that’s when the best risk-adjusted deals appear. When cap rates are compressed and everybody and their brother wants to be a real estate investor, that’s when you’re paying the most per dollar of income.
I’m not saying you should try to time the market perfectly (nobody can). But understanding where we are in the cycle should absolutely influence how aggressively you bid and what kind of deals you pursue.
How Investors Actually Use Cap Rates
Theory is great but lets talk about how this works in practice.
Comparing Deals
This is the most common use case. You’re looking at three properties in different parts of town. They’re different sizes, different ages, different rents. How do you compare them? Cap rate. It normalizes everything into a single yield number. Property A is a 5.2% cap, Property B is a 6.8% cap, Property C is a 4.9% cap. Now you can have a meaningful conversation about why B has a higher yield (is it the neighborhood? the condition? the tenant mix?) and whether that premium compensates you for the additional risk.
Pricing Properties
If you know the NOI and the market cap rate, you can back into what a property should be worth. A property generating $40,000 in NOI in a market where comparable assets trade at a 6% cap should be worth approximately $667,000 ($40,000 / 0.06). If it’s listed at $800,000, either the seller is dreaming or there’s something about the property that justifies a lower cap rate (maybe it’s a newer build in a premium location).
Identifying Undervalued Properties
This is where it gets fun. If you find a property trading at an 8% cap rate in a market where similar properties trade at 6%, something is going on. Maybe the current owner is managing it poorly and rents are below market. Maybe there’s deferred maintenance scaring off other buyers. Maybe the seller just needs to close fast. If you can fix whatever is depressing the income, you can push the cap rate down toward market and create equity through operations rather than just hoping for appreciation.
I recently worked with an investor who bought a small multifamily property at what looked like a 7.5% cap rate. The previous owner was self-managing, hadn’t raised rents in three years, and had two units below market. After bringing rents to market and tightening operations, the effective cap rate on their purchase price dropped to about 5.8%. On paper, they “created” over $80,000 in equity without spending a dime on renovations. That’s the power of understanding cap rates.
Market Timing (Sort Of)
I said sort of because I don’t believe in timing markets precisely. But if you’re watching cap rates expand in your target market, you know that pricing power is shifting toward buyers. If cap rates are compressing, sellers have more leverage. You should always know the general direction of cap rates in your market even if you’re not trying to pick the exact bottom.
The Inverse Relationship: Lower Cap Rate = Higher Price
This trips people up so lets be really clear about it. Cap rate and price move in opposite directions when NOI stays constant.
Lower cap rate = higher price = lower perceived risk. Investors are willing to accept less current income because they believe the income is more stable, the location is desirable, or appreciation will make up the difference.
Higher cap rate = lower price = higher perceived risk. The market is demanding a higher yield to compensate for uncertainty. Maybe the building needs work, maybe the area is declining, maybe the tenant base is unstable.
So when someone tells you they “only buy high cap rate deals,” what they’re really saying is they buy higher-risk properties. That can absolutely work if they have the skills to manage those risks. But it’s not inherently better than buying a low cap rate deal in a premium market. The best investors I know buy at whatever cap rate makes sense for their strategy and risk tolerance. There’s no magic number.
Limitations of Cap Rate (What It Doesn’t Tell You)
I’d be doing you a disservice if I didn’t talk about what cap rate misses. Because it misses a lot.
It ignores financing. Cap rate treats every purchase as all-cash. But in reality, leverage changes everything. A 5% cap rate property with 75% LTV at a 6.5% interest rate has negative leverage, meaning the debt costs more than the property yields. That matters. A lot. This is why you need cash-on-cash return as a companion metric.
It ignores capital expenditures. The formula uses NOI, which is a normalized number. But real properties need real repairs. A new roof, HVAC replacement, parking lot resurfacing. These costs can destroy your actual returns even if the cap rate looks great on paper. Always model CapEx reserves separately.
It uses a snapshot in time. Cap rate captures one year of income at one moment. It doesn’t account for rent growth, expense escalation, or market changes. A property with a 6% cap rate today might effectively be a 7.5% cap rate in three years if rents grow 8% annually. Or it might be a 4% cap rate if the anchor tenant leaves.
It can be manipulated. Sellers (and their brokers) can present “pro forma” cap rates based on projected rents that haven’t been achieved yet. Always calculate cap rate based on actual, in-place income. If someone shows you a “pro forma 8% cap” and the actual in-place cap is 5%, that 3% gap represents hope, not income.
It doesn’t work well for value-add or development. If a property is 50% occupied or under renovation, the current NOI is meaningless. Cap rate is most useful for stabilized, income-producing properties. For everything else, you need DSCR analysis and more detailed underwriting.
Using Cap Rates to Find Undervalued Properties
Ok so here’s the practical application that actually makes you money. There are really two ways to use cap rates to find value.
Method 1: The Cap Rate Spread
Compare a property’s cap rate to the average cap rate for its submarket and property type. If the property is trading 100+ basis points above the market average, figure out why. Is the reason fixable? If it’s bad management, below-market rents, or cosmetic issues, you might have a value-add opportunity. If it’s structural (contamination, zoning restrictions, declining neighborhood), walk away.
Method 2: The NOI Gap
Look at the property’s current NOI versus its potential NOI. Maybe rents are $200/unit below market. Maybe vacancy is 15% when the submarket average is 6%. Maybe expenses are bloated because the owner is paying retail for every service. If you can close the NOI gap, you’ll compress the cap rate on your purchase price and create value.
Either way, the math is straightforward. Buy at a high cap rate relative to the market, improve operations to increase NOI, and the market reprices your property at a lower cap rate (higher value). That’s the buy and hold wealth creation engine in one sentence.
And look, this isn’t just for big commercial deals. I’ve seen this work on duplexes, fourplexes, even single-family rentals. The principle is universal. Know the market cap rate. Buy below it. Operate better than the previous owner. The math does the rest.

Ready to Run the Numbers on a Real Deal?
Cap rate is the starting line, not the finish line. It gets you to “is this deal even worth looking at” faster than any other metric. But you still need to model the financing, stress-test the assumptions, and walk the property before you write a check.
