“Is this a good cap rate?” is one of the most common questions in real estate underwriting — and one of the least useful ways to frame it. A 6% cap rate can be outstanding or deeply inadequate depending on the market, the property class, and the interest rate environment. The right question is: is this cap rate appropriate for what this asset is, where it is, and what rates are doing right now?
Below are the institutional benchmarks, the data behind them, and a framework for applying them to a specific deal.
The Short Answer: Benchmarks by Market Tier
CBRE’s Cap Rate Survey, the benchmark for institutional real estate pricing, segments the market along four dimensions: asset class, property quality (A/B/C), market tier, and investment style. The ranges below reflect stabilized, well-located assets in each tier — not distressed, vacant, or value-add situations.
The spread between primary and tertiary markets averages roughly 130 basis points for equivalent property quality, a spread that holds across property types. A Class B property in a tertiary market should trade at a higher cap rate than a Class B property in a primary market — you are being compensated for the illiquidity and market risk premium.
Cap Rate by Property Class (A, B, C)
Within any market tier, property class drives the second layer of cap rate variance. Academic research (Larriva and Linneman, 2022) quantifies the typical class premium:
| Property Class | Description | Premium Over Class A | Typical Primary Market Range |
|---|---|---|---|
| Class A | Built last 10–15 years, institutional quality, top submarket | — | 4.5–5.5% |
| Class B | 10–30 years old, functional but not luxury, solid location | ~110 bps | 5.5–6.5% |
| Class C | 30+ years, dated finishes, workforce housing, often secondary location | ~200–300 bps | 7.0–8.5%+ |
These premiums compound with market tier. A Class C property in a tertiary market should carry a materially higher cap rate than Class A primary: the 130bps market tier premium plus the 200–300bps class premium means you should expect 330–430bps over what Class A primary trades at. If you are not getting that spread, you are either mispricing the risk or the seller is.
SFR and small multifamily (2–4 units): Single-family rentals and duplexes/triplexes are priced in the same range as the multifamily benchmarks above. Small residential rentals typically trade at 5.0–7.0% depending on location and quality — closer to the Class B secondary range, since they are not institutional assets but also not distressed Class C. Their cap rates reflect the local SFR ownership market, not the institutional multifamily market.
The Rate Spread Test: The Institutional Floor
Market-tier benchmarks tell you what properties are trading at. The rate spread test tells you whether what they are trading at is rational given the interest rate environment.
The Spread Framework
Investors require a spread over the risk-free rate to compensate for real estate’s illiquidity, management burden, and concentration risk. Historically, Class A multifamily has traded at 150–200 basis points over 10-year Treasuries in primary markets. Research by Tsui and Morgan (UNC, 2025) found that approximately 88% of multifamily cap rate variance over time is explained by just three factors: the 10-year Treasury yield, the prior year’s cap rate, and expected revenue growth.
The spread benchmark gives you a rate-environment-adjusted floor. In a 4–5% Treasury environment, here is what the spread implies for different cap rates:
| Cap Rate | Spread vs. 4.5% Treasury | Assessment |
|---|---|---|
| 5.0% | +50 bps | Too compressed for anything outside Class A gateway — appreciation-dependent |
| 5.5% | +100 bps | Acceptable for Class A primary only; thin everywhere else |
| 6.0% | +150 bps | At the institutional floor for Class A primary; reasonable for Class B secondary |
| 6.5% | +200 bps | Healthy for Class B secondary, appropriate for Class B tertiary or Class C secondary |
| 7.0%+ | +250 bps+ | Compensates for Class C or tertiary risk; income-driven profile starts to work |
The practical implication: when Treasuries were at 1.5% in 2021, a 4.5% cap rate in a primary market still provided 300 basis points of spread over the risk-free rate. That same 4.5% cap rate at a 4.5% Treasury means you are earning precisely the risk-free rate — zero compensation for any of the risks of real estate ownership. This is why deals that looked disciplined in 2020 and 2021 repriced sharply when rates normalized.
The 2022–2023 lesson: The Federal Reserve raised the federal funds rate by more than 500 basis points over 16 months. The 10-year yield moved from below 2% to nearly 5%. Cap rates in many markets lagged the rate move — sellers were slow to reprice and buyers were slow to walk. Properties that traded at 4.5% cap rates in 2021 required repricing to 6–6.5% by 2023 to offer the same spread over Treasuries. That repricing cost some buyers 25–35% of nominal value with no change to the underlying income — the math of a 4.5%→6.5% cap rate expansion on any fixed NOI is a 31% value decline. The spread test would have flagged those deals as compressed before the repricing happened.
Rate Sensitivity: How Much Cap Rates Actually Move
Cap rates and Treasury yields do not move one-for-one. Research by Tsui and Morgan (UNC, 2025) on multifamily cap rates found that a 100-basis-point increase in 10-year Treasury yields corresponds to approximately a 32-basis-point increase in multifamily cap rates. Industrial shows a 28-basis-point response; office shows a 40-basis-point response.
This partial pass-through has two implications:
- Cap rates do not immediately adjust to rate moves. When the 10-year rises sharply, the initial result is a compressed spread — real estate appears more expensive relative to Treasuries. Cap rates catch up over 12–24 months as deal volume adjusts and price discovery happens. This is why real estate valuations lag rate cycles.
- Rising rates compress the income cushion. If cap rates only move 32 basis points for every 100-basis-point rate increase, buyers who acquired at tight spreads see their spread erode even if cap rates technically rise. A buyer who acquired at 5.5% when 10-year was 3.0% (250bps spread) watched the same 5.5% asset become 50bps over the risk-free rate when the 10-year hit 5.0% — not because anything changed with the property, but because the risk-free alternative got more competitive.
The Same NOI at Different Cap Rates: Value Sensitivity
The reason cap rate benchmarks matter for buyers is value, not yield. A property with $18,000 of annual NOI prices very differently across the cap rate spectrum:
| Cap Rate | Implied Value ($18,000 NOI) | Change from 5.5% Base |
|---|---|---|
| 5.0% | $360,000 | +$32,727 (+10.0%) |
| 5.5% | $327,273 | — base case |
| 6.0% | $300,000 | −$27,273 (−8.3%) |
| 6.5% | $276,923 | −$50,350 (−15.4%) |
| 7.0% | $257,143 | −$70,130 (−21.4%) |
| 7.5% | $240,000 | −$87,273 (−26.7%) |
The same income stream produces prices across a $120,000 range depending solely on what cap rate the market assigns to the asset. Acquiring at 5.5% when the market reprices to 7.0% produces a 21.4% paper loss on the same NOI — before any change in the underlying property. This is the central risk of buying at compressed cap rates: you are betting that the spread stays where it is, which is a bet on rate and sentiment stability that sellers never compensate you for.
How to Evaluate a Specific Deal
The benchmarks above give you a context. Here is how to use them when you have an actual number in front of you.
Step 1: Classify the asset. Primary, secondary, or tertiary market? Class A, B, or C? That narrows your benchmark range to a 150–200bps window.
Step 2: Check the rate spread. Calculate the spread over the current 10-year Treasury yield. If it is below 150bps for a Class A primary, or below 200bps for anything lower quality, you are outside the range where institutional buyers have historically been compensated for real estate risk. That does not mean it is a bad deal — but it means your return thesis depends on something other than income.
Step 3: Verify the NOI. The cap rate is only as good as the NOI underneath it. The single most common valuation error is using a seller’s pro-forma NOI that omits management fees, capital reserves, or realistic vacancy. Recalculate NOI with a fully-loaded expense stack. The cap rate that results from a clean NOI is the one worth comparing to benchmarks.
Step 4: Run DSCR and CoC. A cap rate that passes the first three steps is still insufficient for a leveraged acquisition. Cap rate is an unlevered metric; it tells you nothing about whether the deal finances. Run DSCR to confirm you can get the loan, then run cash-on-cash return to see what your equity earns after debt service. All three checks — cap rate, DSCR, CoC — need to pass before the deal warrants deep analysis.
The three-check sequence: A deal that clears (1) appropriate cap rate for market and class, (2) DSCR ≥1.20–1.25x, and (3) cash-on-cash return above your floor is a deal worth modeling in depth. A deal that fails any single check needs renegotiation before you spend more time on it. Cap rate benchmarks identify which deals are worth proceeding to steps two and three.

What is a good cap rate for rental property in 2026?
It depends on market tier and property class. Class A properties in primary markets (major coastal and Sunbelt metros) typically trade at 4.5–5.5%. Class B properties in secondary markets run 5.5–7%. Class C and higher-yield properties in tertiary markets reach 7–9%+. The institutional benchmark is the spread over the 10-year Treasury: historically, Class A multifamily has traded at 150–200bps over 10-year yields. In a 4–5% Treasury environment, a 6–7% cap rate on a well-located secondary-market rental represents a reasonable spread. Below 5% in most non-gateway markets means you are buying on appreciation expectations, not income.
Is a 5% cap rate good?
A 5% cap rate can be appropriate or too thin depending on context. In a primary market — major coastal metro, Class A multifamily — 5% is within the institutional norm. In a secondary or tertiary market, 5% is likely thin: the same yield is available on safer assets, and the illiquidity and management burden of a rental are not being compensated. The test: what is the spread over the 10-year Treasury? At a 4–4.5% Treasury, a 5% cap rate is only 50–100bps over the risk-free rate — tighter than the 150–200bps that Class A primary markets historically command. You need an appreciation thesis, below-market rents, or value-add angle to justify buying at 5% outside a gateway market.
What is a good cap rate for commercial real estate?
Commercial real estate cap rates are materially higher than residential, and vary by property type. Stabilized industrial and warehouse: 5–7% depending on market and tenant credit. Retail (anchored strip): 6–8%. Office: 7–10%+ in 2025–2026 given remote-work headwinds and vacancy pressure. Net-lease single-tenant (NNN): 5–7% for investment-grade tenants, 7–9%+ for non-investment-grade. The spread-over-Treasury framework applies across all types: if commercial cap rates do not compensate for illiquidity, lease rollover risk, and credit risk versus a Treasury, the deal is priced too aggressively.
How does the interest rate environment affect what is a good cap rate?
Cap rates and interest rates are correlated, though the relationship is lagged and partial. Research by Tsui and Morgan (UNC, 2025) found that a 100-basis-point move in 10-year Treasury yields corresponds to approximately a 32-basis-point move in multifamily cap rates. This means rising rates compress the spread — the income cushion over risk-free rates shrinks unless cap rates expand to compensate. In a 4–5% Treasury environment, buyers who accept 5% cap rates on properties that are not Class A gateway assets are leaving minimal cushion for rate volatility, lease-up risk, or unexpected capex. The institutional floor shifts with rates; what was reasonable at a 1.5% Treasury in 2021 is not the same at a 4.5% Treasury in 2026.
