Residential property is valued by comparison. You look at what similar houses sold for, adjust for condition and location, and arrive at a market value. Commercial property is valued differently. The driver is income, not comparison.
Understanding commercial valuation is essential before you make your first offer. Overpaying on a commercial deal is easy if you approach it with a residential mindset.
The yield: the single most important number
In commercial property, the yield is the ratio of net rental income to the property’s capital value. It is expressed as a percentage. A property that generates GBP 50,000 per annum in rent and is valued at GBP 625,000 has a yield of 8%.
Yield is the primary valuation tool. If you know the rent a property produces, you can calculate its value by applying the yield that the market demands for that type of asset in that location.
The formula is simple: value = net annual income / yield.
A retail unit on a Portsmouth high street producing GBP 30,000 per annum in rent, at a market yield of 8%, is worth approximately GBP 375,000. If the market yield is 9%, the same unit is worth GBP 333,333. Small yield shifts produce significant value changes.
Passing rent versus estimated rental value
This distinction is critical. Passing rent is what the tenant actually pays. Estimated rental value (ERV) is what the property could achieve if let today at market rates.
The gap between passing rent and ERV is where value-add investment lives. If you buy a property where the passing rent is GBP 20,000 but the ERV is GBP 30,000, closing that gap through refurbishment or lease restructuring increases both income and capital value.
Do not underwrite a deal on ERV alone. Base your purchase on the income that exists today, and treat the ERV upside as your value creation target.
What affects commercial yields
Location matters in commercial, but not in the same way as residential. A commercial yield reflects:
– Tenant covenant strength (a government tenant yields less than a local start-up because the risk is lower)
– Lease length (longer leases command lower yields)
– Property condition and obsolescence risk
– Market liquidity for that type of asset
– Local demand for commercial space
On the South Coast, yields vary significantly. A well-let office building in Southampton city centre with a government tenant on a 15-year lease might trade at 6%. A parade of shops in a secondary Portsmouth location with mixed tenancy lengths might trade at 9% to 10%.
Capitalisation rate method
The capitalisation rate, or cap rate, is the professional term for the yield used in valuation. It is the rate of return an investor would expect on that asset in that market.
To value a commercial property using the cap rate method:
– Determine the net operating income (gross rent less non-recoverable costs)
– Identify the cap rate for comparable properties in that location and asset class
– Divide the net operating income by the cap rate
This is the most common commercial valuation method and the one you will see in professional valuations and loan appraisals.
Comparing industrial, retail, and office yields
Different asset classes have different yield profiles:
– Industrial properties (warehouses, light industrial units) typically offer the most attractive yields because they are less fashionable but have resilient tenant demand. On the South Coast, industrial yields of 8% to 11% are common.
– Retail yields vary enormously by location. Prime retail in good locations might yield 5% to 7%. Secondary retail on struggling high streets might yield 10% or more, reflecting higher vacancy risk.
– Office yields sit between retail and industrial, typically 7% to 10% for secondary space. Prime offices command lower yields due to stronger tenant demand.
Final thought
Commercial valuation is not complicated, but it does require a different framework from residential. Learn to think in yields, understand the gap between passing rent and ERV, and always underwrite on the income that exists today rather than the income you hope to create.
