Net operating income (NOI): The cornerstone of any commercial property valuation is the net operating income. This figure represents the property's gross annual rental income minus operating expenses such as property management fees, maintenance costs, and insurance. A higher NOI typically indicates a more valuable property, as it directly reflects the building's income potential.

Cap rate: The capitalisation rate, or cap rate, is a critical metric in valuing a commercial property. It is calculated by dividing the NOI by the current market value or purchase price of the property. The cap rate offers insights into the expected rate of return on the investment. Properties in prime locations with stable tenants often have lower cap rates, reflecting lower risk and higher property value.

Location and market conditions: The property's location, including its proximity to transportation hubs, business districts, and other commercial spaces, significantly influences its value. Market conditions, such as supply and demand dynamics, economic growth, and interest rates, also play a pivotal role in determining the commercial property's value.

Land and construction costs: The underlying land value and construction costs are fundamental in the valuation process. In markets where land value is high, the property's overall worth is likely to be elevated. Similarly, rising construction costs can increase the building's replacement cost, thus impacting the property's market value.

Property's detailed characteristics: The physical attributes of the property, such as square footage, building age, design quality, and available amenities, are critical in assessing the value per door. High-quality construction and modern amenities can enhance the property's appeal, leading to a higher gross rent and, consequently, a higher property valuation.

Valuing a commercial property requires the use of multiple valuation methods to ensure an accurate assessment. Each approach provides a different perspective on the property's value, and the choice of method often depends on the property type and the investor's objectives.

• Income approach: Focuses on the net operating income the property generates, adjusted for the current market cap rate. This method is particularly relevant for properties with tenants and leases.
• Sales comparison approach: Compares the property in question with similar properties that have recently sold in the same area. Adjustments are made for differences in size, condition, and location.
• Cost approach: Calculates the cost of land and construction, minus depreciation, to estimate the property's current value. This method is often used for newer properties.

While each of these approaches to commercial valuation provides insights into the property’s potential income and competitive positioning within the current market, there are other factors that can also affect valuation.

• Sector yield comparisons: The various sectors within the commercial space are subject to different yields based on investor demand. For instance, since the Covid pandemic, warehousing has had a very tight yield due to the demand for this type of investment following changes in global buying habits.
• Tenant covenant strength: Letting to more secure, established, reliable tenants is naturally less risky, and you are more likely to receive the entire rental sum contracted by the lease. Therefore, a tenant with a stronger covenant will attract a tighter yield than one with a weaker covenant.
• Voids: As lease lengths have reduced over the years, void costs such as rates, service charges and marketing all play a huge role in producing the net income over the investment lifespan of a property. A building with a better pitch and good fit-out is more likely to quickly be re-let than a building in a sub-prime location.

The perception of when the yield market will change is also an important aspect to consider. Anticipating demand in certain sectors can lead to better valuations in those sectors, and commercial property experts will naturally focus their investment where they perceive the market is heading.
