Cap Rate Explained

If you’re evaluating a commercial property—whether you’re buying, refinancing, or deciding when to sell—there’s one number every investor, broker, and lender will ask for: the cap rate. It’s the fastest way to compare properties, estimate value, and judge whether a deal makes sense. Understanding cap rate isn’t optional in commercial real estate—it’s the language the market speaks.

What Is Cap Rate in Commercial Real Estate?

Capitalization rate (cap rate) is the annual return a property generates relative to its purchase price or current value, assuming an all-cash purchase. It’s calculated as:

Cap Rate = (Net Operating Income ÷ Property Value) × 100

Example: You own a retail plaza generating $150,000 in annual net operating income (NOI). The property is valued at $2,000,000. The cap rate is:

($150,000 ÷ $2,000,000) × 100 = 7.5% cap rate

A higher cap rate means higher yield but usually higher risk (secondary markets, older properties, weaker tenants). A lower cap rate means lower yield but lower risk (Class A buildings, institutional-grade tenants, core locations).

How to Calculate Cap Rate for Your Property

The formula is simple, but getting it right requires two accurate inputs:

1. Net Operating Income (NOI)

NOI is your property’s annual income after operating expenses but before debt service and taxes. It’s:

NOI = Gross Income – Operating Expenses

• Include: rent, parking, laundry, storage, reimbursements (CAM, taxes, insurance)
• Subtract: property taxes, insurance, maintenance, management fees, utilities, reserves
• Exclude: mortgage payments, depreciation, capital improvements, income taxes

2. Property Value

Use the current market value or purchase price, not what you paid five years ago. Lenders and appraisers use the present value.

Worked Example:

• Property type: Multifamily (50 units)
• Gross annual rent: $600,000
• Operating expenses: $240,000
• NOI: $360,000
• Current market value: $5,000,000

Cap Rate = ($360,000 ÷ $5,000,000) × 100 = 7.2%

If you’re refinancing, lenders will order an appraisal that estimates market value by looking at comparable sales and their cap rates. If similar buildings are trading at 7% caps, yours will be valued accordingly—which directly affects your loan sizing and LTV ratio.

What Lenders Want to See: Cap Rate Benchmarks by Property Type

Underwriters use cap rate as a risk and value signal. A 4% cap in Manhattan might be normal; a 4% cap in a tertiary market is a red flag (you’re overpaying). A 10% cap on a stabilized asset in a strong market screams risk (high vacancy, bad location, or operational problems).

Typical Cap Rate Ranges by Property Type (U.S. Markets, 2026):

Property Type	Core Markets (Gateway)	Secondary Markets	Tertiary Markets
Multifamily (Class A)	4.0–5.5%	5.5–7.0%	7.0–9.0%
Office (CBD, Class A)	5.0–6.5%	6.5–8.0%	8.0–10.0%
Retail (Anchored)	6.0–7.5%	7.5–9.0%	9.0–11.0%
Industrial/Warehouse	4.5–6.0%	6.0–7.5%	7.5–9.5%
Self-Storage	6.0–7.5%	7.5–9.0%	9.0–11.0%
Hotel	7.0–9.0%	9.0–11.0%	11.0–14.0%

Core = NYC, SF, LA, DC, Boston, Seattle Secondary = Austin, Denver, Phoenix, Charlotte, Nashville Tertiary = Smaller MSAs, rural markets

If you’re refinancing and your property’s cap rate is below market, that’s good—it means you’re likely sitting on equity (the appraisal will come in high). If your cap rate is above market, you may have valuation headwinds that constrain your loan sizing.

Lenders also cross-check cap rate against DSCR (debt service coverage ratio). A 5% cap on a levered property might only deliver 1.15x DSCR, which is tight. An 8% cap on the same property might deliver 1.40x DSCR, which is strong. Both metrics matter.

How to Improve (or Interpret) Your Cap Rate

Cap rate isn’t something you “fix” like DSCR or LTV—it’s a reflection of market perception and property performance. But you can influence it:

1. Increase NOI

The numerator in the cap rate formula. Raise NOI by:

• Raising rents to market (if you’re under-rented)
• Reducing vacancy through better marketing or tenant retention
• Cutting operating expenses without sacrificing service (renegotiate contracts, improve efficiency)
• Adding income streams (parking, storage, laundry, pet fees)

A 10% NOI increase on a $5M property at a 7% cap adds $714K in value (assuming cap rate stays constant).

2. Understand Market Compression

If market cap rates are compressing (trending lower), your property is appreciating even if NOI stays flat. Example: You bought at an 8% cap; the market is now trading at 6.5% caps. Your property is worth ~23% more, which unlocks equity for a cash-out refinance.

3. Know When a High Cap Rate Is a Red Flag

A 10% cap rate on a stabilized multifamily property in a decent market means one of three things:

1. The building has serious deferred maintenance or operational problems
2. The location is deteriorating (crime, job loss, population decline)
3. The seller is desperate (foreclosure, estate sale, distressed fund exit)

High cap rates = high risk. If you’re refinancing and the appraiser lands at a high cap, expect loan sizing to be conservative—lenders will assume downside risk.

4. Use Cap Rate to Estimate Value

Flip the formula around:

Property Value = NOI ÷ Cap Rate

If your building generates $400K NOI and market cap rates are 6.5%, your property is worth:

$400,000 ÷ 0.065 = $6,153,846

This is exactly how appraisers estimate value using the income approach. If you can raise NOI to $450K, the value jumps to $6,923,077—an extra $769K in appraised value, which increases your refinance proceeds at the same LTV.

FAQ: Capitalization Rate in Commercial Refinancing

What is a good cap rate for commercial property? Depends on location and asset class. Core markets (NYC, SF, DC) run 4–6% for institutional-grade assets. Secondary markets run 6–9%. Anything above 10% is either a value-add opportunity or a distressed asset—proceed with caution.

How is cap rate different from ROI? Cap rate measures unleveraged annual return (NOI ÷ value). ROI (return on investment) measures your total return including appreciation, debt paydown, and tax benefits. Cap rate is a snapshot; ROI is the full picture over time.

Does a higher cap rate mean a better deal? Not necessarily. Higher cap rates often signal higher risk—older buildings, weaker locations, unstable tenants. A 9% cap in a declining market might be a worse investment than a 5% cap in a growth market.

Can I negotiate cap rate when refinancing? No—cap rate is set by the market (what comparable properties are trading for), not by negotiation. But you can influence the inputs: boost NOI to increase value at the same cap rate, or wait for market cap rates to compress (which increases your property value).

What’s the difference between cap rate and cash-on-cash return? Cap rate assumes an all-cash purchase (no leverage). Cash-on-cash return measures your actual annual cash flow divided by the cash you invested (down payment + closing costs). If you finance a property, your cash-on-cash return can be much higher than the cap rate due to leverage.

How do lenders use cap rate in underwriting? Lenders check if your property’s cap rate is in line with market comps. If your cap rate is abnormally low (you overpaid) or abnormally high (red flag), they’ll scrutinize the deal harder and may use a higher cap rate in their valuation, which lowers your appraised value and limits your loan size.
