A high-value commercial property can create the illusion of safety. A prominent location, recognised tenant and substantial valuation may suggest that risk is low. In reality, large assets can concentrate several forms of exposure in a single investment.
For Australian investors, rigorous risk assessment should extend well beyond a building inspection and review of the current rent.
Start with the income, not the building
Commercial property derives its value primarily from future income. The first task is therefore to establish how dependable that income really is.
Questions should include:
- Who ultimately guarantees the lease?
- How strong is the tenant’s balance sheet?
- Is the tenant profitable at this location?
- Does the property remain suitable for the tenant’s operations?
- Are there break rights, contraction rights or make-good disputes?
- How does passing rent compare with market rent?
- What incentives would be required to replace the tenant?
A lease may be legally binding but economically fragile. If premises are no longer useful to the occupier, the landlord may eventually face pressure for concessions, subleasing or an early surrender.
Measure concentration risk
Large properties often depend on a small number of tenants. This creates concentration risk at both asset and portfolio level.
A long lease to one occupier can produce stable income, but the eventual vacancy may be expensive. The owner could face lost rent, incentives, refurbishment costs and an extended letting campaign simultaneously.
Investors should model the cost of losing each major tenant, including a realistic period of vacancy and the capital required to return the space to market.
Examine lease-expiry clusters
A portfolio with a seven-year WALE may still be exposed if several leases expire in the same year. The same applies to a mixed-use asset if its largest occupants have aligned review or termination dates.
A lease-expiry schedule should be considered alongside:
- Tenant size and credit quality
- Renewal likelihood
- Market supply at expiry
- Expected incentives
- Refurbishment requirements
- Debt maturity dates
The combination of a major expiry and a refinancing event can create considerably more risk than either event in isolation.
Look beneath the capitalisation rate
A valuation is sensitive to both income and the rate at which that income is capitalised. Small changes in either variable can produce a substantial change in value.
Investors should test:
- A softer capitalisation rate
- Reduced market rent
- Higher incentives
- A longer letting period
- Increased operating costs
- Unplanned capital expenditure
- Higher interest costs
- A lower valuation at refinancing
The most useful stress test is not an extreme disaster scenario. It is a credible combination of adverse conditions that could occur together.
Assess physical and functional obsolescence
Technical due diligence should identify more than visible defects. It should examine the remaining life and replacement cost of lifts, air-conditioning, fire systems, roofing, electrical infrastructure and building-management systems.
Functional obsolescence is equally important. Low ceiling heights, inefficient floorplates, limited loading facilities, insufficient power capacity or poor accessibility can restrict future tenant demand even if the property is structurally sound.
A capital expenditure forecast should cover the entire proposed holding period, not just immediate repairs.
Understand planning and environmental exposure
Planning controls can either preserve value or restrict future use. Investors should verify permitted uses, existing approvals, heritage constraints, easements, access arrangements and the legality of current improvements.
Environmental investigations may be appropriate for industrial land, service stations, manufacturing properties and sites with potentially contaminating historical uses. Flood, bushfire and climate exposure should also be considered where relevant, together with the availability and cost of insurance.
Analyse finance risk separately
A good property can become a poor investment if its capital structure is too aggressive.
Key measures include:
- Loan-to-value ratio
- Interest-cover ratio
- Debt-service coverage
- Covenant headroom
- Hedging arrangements
- Loan maturity
- Recourse and guarantee provisions
- The ability to fund leasing and capital works
Investors should calculate these measures using stressed income and interest costs, not only the acquisition case.
Build a decision-ready risk register
A disciplined acquisition process converts findings into a risk register. Each issue should identify its potential financial impact, probability, mitigation strategy and responsible party.
Risks can then be classified as:
- Acceptable at the proposed price
- Capable of being mitigated through contract terms
- Requiring a price adjustment
- Requiring additional equity or reserves
- Unacceptable regardless of price
The purpose of due diligence is not to prove that an asset is perfect. No commercial property is. It is to understand which risks the investor is accepting, whether those risks are adequately priced and whether the portfolio can absorb an adverse outcome.
