Reading yield metrics like a real estate investor

Worked example:

An office building sells for $20 million. In-place NOI is $1.2 million.

Cap Rate = $1,200,000 ÷ $20,000,000 = 6.0%

Simple. But the number hides a lot: How long are the leases? Is a tenant about to vacate? Is NOI "stabilized" (normalized) or does it include a rent-free period ending soon? Two buildings at the same 6% cap rate can carry very different risk if one has 10-year leases to investment-grade tenants and the other has month-to-month tenants.

As of 2025, US office cap rates for prime, well-let assets in top-tier markets are estimated in the 6% to 8% range, with distressed or older-vintage office often quoted higher (estimate, varies significantly by market and asset quality; see NCREIF for institutional benchmark data).

European convention: initial yield and equivalent yield

Continental Europe and the UK use a different vocabulary, rooted in a valuation tradition that separates *current* income from *future* income potential.

Initial yield

This is the European cousin of the cap rate, but calculated on a gross basis before certain costs.

Initial Yield = Annual Passing Rent ÷ Gross Purchase Price (including buyer's costs)

"Passing rent" means the rent currently being paid, not a normalized or projected figure. Critically, UK convention includes purchase costs (stamp duty, legal fees, agent fees) in the denominator, typically adding an estimated 5% to 7% to the price depending on the jurisdiction and deal size. This alone makes a UK initial yield lower than a US cap rate calculated on the same building at the same rent, purely due to the denominator.

Equivalent yield

This is where European practice gets genuinely more sophisticated than the simple cap rate. The equivalent yield is a weighted average between the initial yield (income now) and the reversionary yield (income once the property reaches its estimated rental value, or ERV, at the next rent review or lease renewal).

Why does this matter? European leases, especially in the UK, historically feature long terms with periodic rent reviews (often every 5 years) rather than the annual escalations common in US leases. If passing rent is below current market rent (the property is "under-rented"), there's a built-in uplift coming. The equivalent yield captures that expectation in a single discount rate, effectively used like an internal rate of returninternal rate of returnThe Internal Rate of Return is the discount rate that makes a project's net present value equal zero.

Worked example:

A London office is let at a passing rent of £2 million a year, but current market rent (ERV) for comparable space is £2.4 million. The lease has a rent review in 3 years.

• Initial yield at a £30 million gross price: £2,000,000 ÷ £30,000,000 = 6.67%
• Reversionary yield (once rent moves to ERV): £2,400,000 ÷ £30,000,000 = 8.0%
• Equivalent yield sits between the two, weighted by timing, an estimated 7.2% to 7.4% in this simplified case, reflecting that the uplift arrives in year 3, not immediately.

A US cap rate has no native equivalent to this reversion concept. US appraisers instead build the rent bump into a multi-year discounted cash flowdiscounted cash flowDiscounted Cash Flow (DCF) is a valuation method that estimates an asset's value by projecting future cash flows and discounting them to present value using a required rate of return.View full definition → (DCFDCFDiscounted Cash Flow (DCF) is a valuation method that estimates an asset's value by projecting future cash flows and discounting them to present value using a required rate of return.View full definition →) and quote a "going-in cap rate" alongside a separate "terminal cap rate" for exit.

Why the same number can mean different risk

Circle back to the hook: a 6% cap rate in Dallas and a 6% initial yield in Frankfurt.

| Feature | US 6% Cap Rate | European 6% Initial Yield |

|---|---|---|

| Cost basis | Usually excludes transaction costs | UK convention includes buyer's costs in denominator |

| Income basis | Often "in-place" or forward 12-month NOI | Strictly current passing rent |

| Lease structure | Often shorter terms, annual bumps | Longer terms, stepped rent reviews |

| Future income | Captured via separate DCFDCFDiscounted Cash Flow (DCF) is a valuation method that estimates an asset's value by projecting future cash flows and discounting them to present value using a required rate of return.View full definition →/terminal cap rate | Captured via equivalent/reversionary yield |

The practical consequence: a European 6% initial yield on an under-rented building with a rent review in two years can be a better risk-adjusted deal than a US 6% cap rate on a fully-rented, no-upside building. Same headline number, different embedded story.

For a rigorous public reference on UK valuation yield definitions, the RICS (Royal Institution of Chartered Surveyors) Red Book is the standard-setting body worth knowing by name.

Reading a quoted yield in practice

When someone hands you a yield number, ask four questions before comparing it to anything else:

1. Gross or net of costs? US cap rates are typically net of transaction costs; UK initial yields typically gross them up in the denominator.

2. Passing rent or projected rent? A cap rate on "pro forma" NOI (management's optimistic future number) is not the same as one on trailing actual NOI.

3. What's the lease structure? Long leases with fixed reviews (common in continental Europe, especially indexed to inflation in markets like France and the Netherlands) behave differently from US leases with annual 2% to 3% escalations.

4. Is there reversion? If passing rent is below market, ask for the reversionary and equivalent yield, not just the initial yield.

A quick gut-check formula worth memorizing for triangulating any deal:

Approximate Value = Stabilized NOI / Target Cap Rate

Example: NOI of $1.5M, target cap rate of 6.5%
Value ≈ $1,500,000 / 0.065 ≈ $23.1 million

Key Takeaways

• Cap rate (US) = NOI ÷ purchase price, typically excluding transaction costs; it's a snapshot, with future rent growth handled separately via DCFDCFDiscounted Cash Flow (DCF) is a valuation method that estimates an asset's value by projecting future cash flows and discounting them to present value using a required rate of return.View full definition → and terminal cap rate assumptions.
• Initial yield (Europe/UK) = passing rent ÷ gross price, often including buyer's transaction costs in the denominator, which mechanically lowers the yield versus a US-style calculation on the same income.
• Equivalent yield blends current income and future reversionary income into one rate, reflecting the UK/European practice of long leases with periodic rent reviews rather than annual US-style escalations.
• The same headline percentage can represent very different risk profiles: always ask whether the yield is gross or net of costs, based on passing or projected rent, and whether reversion is baked in.
• Use direct capitalization (NOI ÷ cap rate) as a fast value check, but treat it as a starting point, not a substitute for a full lease-by-lease cash flow analysis.
