How Is Commercial Property Valued? The Five Methods Valuers Use
- The comparable method uses evidence of similar sales and lettings, and underpins every other method.
- The investment method capitalises rental income at a yield. It is how most let commercial property is valued.
- The profits method values trading property such as hotels and pubs from the business the premises can sustain.
- The residual method is for development land, and depreciated replacement cost is for specialised buildings that rarely sell.
A house is valued by looking at what similar houses sold for. Commercial property is harder, because most of it is bought for the income it produces, some of it is bought for the business it lets you run, and some of it hardly ever sells at all. Valuers have five established methods for these situations. Knowing which one applies to your building tells you what evidence matters and why two valuers might disagree.
1. The comparable method
The simplest idea: find recent transactions of similar properties and adjust for the differences. Size, location, age, specification, condition and lease terms all have to be accounted for. It is the main method for owner-occupied buildings sold with vacant possession, and for assessing rental value.
It is also the foundation of the others, because rents and yields used elsewhere come from comparable evidence. Its weakness is obvious. When few similar properties have changed hands recently, the evidence is thin and judgement fills the gap.
2. The investment method
Most let commercial property is valued this way. The buyer is purchasing an income stream, so value is the rent converted into a capital sum using a yield. In its simplest form:
Value = net annual rent ÷ yield
A building let at £500,000 a year and valued at a 6% yield is worth about £8.33 million. At 6.5% it is worth about £7.69 million. Half a percentage point has moved the value by roughly £640,000, which is why the yield is the most argued-over input on any large asset.
The yield reflects risk and growth: the strength of the tenant, the length of lease remaining, the location, the building’s quality and how easily it could be re-let. The valuer also compares the rent being paid with the current market rent. If the rent is below market, there is growth to come at review. If it is above, the income will fall when the lease ends. Valuers deduct the buyer’s purchase costs to arrive at the net figure. Larger and more complex assets are often tested with a discounted cash flow, which models the income year by year.
3. The profits method
Some properties are bought for the trade they can do, and their value is inseparable from it. Hotels, pubs, care homes, petrol stations and leisure venues are the usual examples. Here the valuer estimates the level of trade a competent operator could maintain, works out the sustainable profit, and capitalises it.
The accounts matter as much as the building. Expect to supply at least three years of trading figures, and expect the valuer to adjust them for anything personal to the current operator.
4. The residual method
This is for land and buildings with development potential. The valuer estimates what the completed scheme would be worth, then deducts the build costs, fees, finance and the developer’s profit. What is left is what a developer could afford to pay for the site.
The method is very sensitive to its inputs. A small change in build cost or end value produces a large change in the residual, so valuers cross-check it against land sales wherever they can.

5. Depreciated replacement cost
Some buildings almost never sell on the open market: specialised industrial plants, schools, some public buildings. With no market evidence, the valuer estimates what it would cost to replace the building with a modern equivalent, deducts an allowance for age and obsolescence, and adds the value of the land. It is mainly used for financial reporting. It should not be confused with an insurance rebuild figure, which is a different calculation explained in market value versus reinstatement cost.
Which method applies to your building?
- Owner-occupied office, shop or warehouse: comparable.
- Let to one or more tenants: investment, supported by comparables.
- Hotel, pub, care home or similar: profits.
- Site with planning or redevelopment potential: residual.
- Specialised building with no market: depreciated replacement cost.
Valuers often use a second method as a check. If two approaches give very different answers, that is a prompt to look again at the assumptions.
What moves the figure whichever method is used
Lease terms, tenant strength, condition and compliance. A building that cannot lawfully be let because its EPC is below the minimum standard is worth less until it is fixed, and the cost of fixing it comes off the value. Known defects from a building survey do the same. Our guide to valuing large commercial buildings looks at these factors in detail.
