What Is a Cap Rate — and Why It Matters for Private Real Estate Lenders

Cap rate, short for capitalization rate, is one of the most quoted numbers in commercial real estate — and one of the most misunderstood. For a private lender, it isn’t just a quick way to size up a deal. It’s a direct input into how much risk sits underneath every income-producing property loan, and getting it wrong in either direction costs real money.

The Cap Rate Formula

Cap rate = Net Operating Income ÷ Property Value. Take a 24-unit apartment complex generating $291,480 in annual NOI, appraised at $4,460,000: that’s a 6.53% cap rate. Flip the formula around and you get Value = NOI ÷ Cap Rate — which is the part that trips people up. Cap rate is simultaneously a yield measure and a valuation multiple, and a small move in it swings value by a lot. Shift that same property’s cap rate just 25 basis points, from 6.50% to 6.75%, and the implied value drops from about $4,484,000 to $4,318,000 — a swing of roughly $166,000 on an income stream that hasn’t changed at all.

Cap Rate as a Risk Signal, Not Just a Valuation Shortcut

Lower cap rates mean investors are paying a premium relative to current income — they’re betting on appreciation, not just today’s cash flow. Coastal multifamily in Los Angeles or San Francisco often trades at 4–5% cap rates for exactly this reason. Higher cap rates point the other way: lower prices relative to income, usually because the market is secondary, the asset type carries more perceived risk, or both — an 8% cap rate strip mall in a smaller Texas market is trading for more current yield and, typically, less appreciation upside. For a lender, the real question isn’t whether a cap rate looks reasonable in isolation. It’s whether the cap rate used in underwriting actually reflects today’s market, not the 2021 peak.

How Lenders Actually Stress-Test a Cap Rate

When a private lender underwrites a bridge loan against an income property, the appraiser selects a market cap rate to arrive at value — and a careful lender doesn’t just accept that number, it pressure-tests it. What happens to the property’s value if cap rates expand 50 to 100 basis points from where they sit today? Take a $4.4 million property valued at a 6.5% cap rate — that implies roughly $286,000 in NOI. If the market cap rate expands to 7.5%, the same NOI only supports a value of about $3.8 million, a 13% drop. If the lender had funded $2.86 million against that property (65% loan-to-value on the original $4.4 million), the loan-to-value ratio under that stressed scenario climbs to roughly 75% — meaningfully thinner protection than the deal looked like on day one, with the income stream itself never having changed.

Going-In Cap Rate vs. Exit Cap Rate

Bridge loans get underwritten against a projected exit, whether that’s a sale or a refinance — which means two cap rates matter, not one. Picture a borrower buying a value-add multifamily property at a 5.5% going-in cap rate on today’s depressed, pre-renovation income, planning to raise rents and exit at a 5.25% cap rate once the property’s stabilized. A careful lender underwrites both numbers: what the property is worth today, and what it’s realistically worth once the business plan plays out. The more conservative move is underwriting the exit cap rate at a slight expansion from the going-in rate, not a compression — building in room for the possibility that market conditions shift somewhere during the renovation and lease-up period, rather than assuming today’s favorable pricing holds indefinitely.

What’s Actually Happening to Cap Rates Right Now

From 2015 through 2022, a near-zero rate environment pushed cap rates down across nearly every commercial asset class — multifamily in major metros compressed from roughly 6–7% down to 4–5%. When rates rose sharply in 2022–2023, cap rates expanded the other way, and property values fell without a single dollar of income changing hands — that’s the direct mechanism linking interest rates to commercial real estate values. Where things stand now is less a single story than a split one. CBRE’s H1 2026 cap rate survey found rates holding broadly stable overall, but diverging sharply by sector: multifamily and lower-quality office are still seeing expansion, while industrial and neighborhood retail are actually compressing — a more complicated picture than a flat “stabilizing” narrative would suggest, and one that lines up with the uneven, asset-specific recovery private lenders are already underwriting around in today’s commercial real estate market.

Property Type Cap Rate Ranges — A General Reference for 2026

As a rough guide, current market data puts multifamily (Class A) cap rates around 4.5–6.0%, industrial big-box in the 5.5–7.0% range, grocery-anchored retail around 6.5–8.0%, and unanchored strip retail at 7.0–9.0%. Office remains the widest spread of any property type — Class A space in strong submarkets can trade at 6.0–8.0%, while Class B and C space, especially anything still working through a lease-up or location problem, often prices at 8.5% and up, sometimes into the double digits. These ranges move constantly with rates and sentiment, and a lender working off stale, 2021-vintage cap rate assumptions is systematically overvaluing collateral and understating real LTV.

What Fund Investors Should Ask About Cap Rates

Anyone evaluating a private lending fund’s income-property exposure should ask a few direct questions: what cap rate was actually used to underwrite each loan against an income-producing property? How does that compare to current market cap rates for the same asset type and location? Has the fund actually run the stress test — what happens to the collateral value, and the resulting LTV, under a 50-basis-point cap rate expansion? A fund that answers all three clearly and conservatively is showing exactly the kind of underwriting discipline that’s supposed to protect investor capital when a cycle turns, which is the same discipline behind LBC Capital’s 10-point fund comparison scorecard — LTV policy, and whether a fund actually sticks to it, is Point 2 on that list for exactly this reason.

If you’d like to see how LBC Capital actually underwrites cap rate risk on a specific property type or market, that’s worth a direct conversation rather than relying on a general reference range.

Frequently Asked Questions

Is a lower cap rate always a safer bet for a lender?

Not necessarily. A lower cap rate means the property is priced at a premium relative to its current income, which leaves less room to absorb a market shift before the loan-to-value ratio gets uncomfortable. A higher cap rate means more current yield, but it often comes with real location or asset-quality trade-offs that need their own scrutiny.

Why would a lender underwrite the exit cap rate higher than the going-in cap rate?

Because the renovation or lease-up period is exactly when things can go sideways — rates can move, demand can soften, timelines can slip. Underwriting the exit at a slightly wider cap rate than the going-in rate builds in a cushion for that uncertainty instead of assuming the property will sell into exactly the same favorable market it was bought in.

How often do cap rates actually change?

Cap rates can move within a single cycle meaningfully — the 2015–2022 compression followed by 2022–2023 expansion is the clearest recent example. They respond to interest rates, investor sentiment, and sector-specific supply and demand, which is exactly why a cap rate assumption needs to reflect current conditions rather than whatever the market was doing a few years back.
