What it means
For non-finance managers, understanding property valuation is essential because real estate often forms a significant portion of a business's total assets. Knowing the true value of your physical premises affects your balance sheet strength, borrowing capacity, and insurance coverage.
When companies need a bank loan, lenders require a professional valuation to ensure the property provides adequate security against the debt. In practice, professionals use three main approaches to determine value.
The market comparison method looks at recent sales of similar properties nearby. The income approach calculates value based on the rental income the property generates, which is common for commercial spaces.
Finally, the cost approach estimates what it would take to rebuild the property from scratch, minus depreciation. Regular valuations protect businesses from holding overvalued assets on their books, which can distort financial ratios and mislead stakeholders.
Whether you are leasing a new office, buying a warehouse, or reviewing your annual financial statements, property valuation ensures your asset records reflect current market realities rather than historical purchase prices. Property valuation is like getting your car appraised before selling it or trading it in.
Just as you cannot rely on what you paid for the vehicle five years ago, a business must check current market conditions to know its true worth today.
In practice
Real-world examples
Example 1
A tech startup looking to secure a commercial bank loan offers its recently purchased office building as collateral. The bank orders a property valuation to confirm the asset is worth at least $500,000 before approving the funds. If the valuer reports only $420,000, the bank may reduce the loan or ask for extra security. The startup learns that the price it paid and the value a lender accepts can differ.
Example 2
A growing retail SME reviews its balance sheet for the annual audit. By updating the valuation of its owned high street shop, the business increases its reported asset base by $150,000. This improves its debt-to-equity ratio and gives lenders a more accurate picture of its strength.
Example 3
A logistics firm planning to expand leases a large distribution hub. Management uses a rental-based valuation model (the income approach) to check whether the landlord's asking price aligns with current market rates for industrial space in that region. If comparable hubs rent for far less per square metre, the firm has strong grounds to negotiate.

Formula
Calculation
Income approach: Value = Net Operating Income / Capitalisation Rate. If a small commercial warehouse generates $50,000 in net annual rent and the local market capitalisation rate is 5%, the value is $50,000 / 0.05 = $1,000,000.
Cost approach: Value = Land Value + Replacement Cost of the Building - Accumulated Depreciation. With land worth $300,000, a rebuild cost of $900,000 and $200,000 of accumulated depreciation, the value is $300,000 + $900,000 - $200,000 = $1,000,000.
Market comparison approach: Value = Average Price per Square Metre of Comparable Sales x Floor Area. If three similar warehouses sold for $1,000, $1,050 and $950 per square metre, the average is ($1,000 + $1,050 + $950) / 3 = $1,000. A 1,000 square metre warehouse is then worth 1,000 x $1,000 = $1,000,000. When all three approaches land close together, the valuer can be more confident in the figure.Case study
Seen in the real world
This is a fictional, illustrative scenario. Oakwood Logistics, a mid-sized distribution company, owned its primary warehouse outright. The building was purchased ten years ago for $800,000 and was still listed at that historical cost on the balance sheet. When Oakwood applied for a $1,200,000 expansion loan, the bank insisted on an independent property valuation.
The certified valuer assessed the warehouse at $1,800,000 after local commercial property prices rose. The bank's lending policy capped loans at 70% of the valuation, which allowed up to $1,260,000 ($1,800,000 x 70%) against the property. At the old figure of $800,000, the limit would have been only $560,000, well short of what Oakwood needed. The $1,200,000 loan was approved at a loan-to-value ratio of 66.7% ($1,200,000 / $1,800,000).
The update also showed Oakwood's true asset base, which improved how the business looked to lenders and investors. Without this updated valuation, Oakwood would have lacked sufficient security to fund its growth plans. The finance manager also scheduled a fresh valuation in four years, so the figures in the accounts and the bank file would not drift apart again.
Watch out
Common mistakes
- Assuming purchase price equals current market value years later.
- Ignoring local market trends and recent comparable sales.
- Mixing up property replacement cost with actual market value.
Questions
People also ask
How often should a business value its property?
Most companies arrange a formal professional valuation every three to five years, or sooner if local market conditions change drastically.
Do I need a certified surveyor for property valuation?
Yes, for official financial statements, tax reporting, and bank loans, you need an independent valuation by a qualified professional.
What is the difference between book value and market value?
Book value is the historical purchase price minus accumulated depreciation, while market value is what the property would sell for today.
