Bifurcation or Stagnation: Is the Commercial Office Valuation Model Evolving?
As vacancy performance diverges between prime and secondary assets, industry discussion remains focused on whether this represents a structural shift or a period of protracted price-discovery. Market observations suggest that liquidity constraints in the secondary segment are creating analytical challenges for traditional valuation models.
The facts, sourced
- CBRE data from April 2026 indicates stagnation in Melbourne CBD office market activity. (CBRE, April 2026)
- Savills analysis (April 2026) suggests that the cost of capital and capex requirements for secondary space are influencing return expectations. (Savills, April 2026)
- HTW research (November 2024) identifies a structural performance divergence where secondary asset vacancy rates have detached from prime performers. (HTW)
The Divergence in Vacancy Metrics
Research by HTW (as of late 2024) indicates a structural detachment in performance between grade levels, moving beyond simple cyclical fluctuations. This divergence suggests that broad-sectoral valuation indexing may face limitations as secondary stock encounters unique structural pressures. Some market participants note that standard models may not fully capture the lack of historical covariance between these segments, leading to discussions regarding the increased importance of asset-specific risk modelling.
The Yield Compression Debate
There is an ongoing discussion regarding the mechanics of yield spreads. Economists suggest that widening spreads are a response to 'flight to quality,' where the capital expenditure required to reposition obsolete stock can impact total return expectations. Conversely, CBRE data from April 2026 for the Melbourne CBD indicates significant stagnation in trade volume, which some analysts suggest may reflect a period where price discovery is influenced by differing vendor and purchaser expectations.
Liquidity and the 'Secondary' Assets
The liquidity outlook for non-prime assets remains a point of observation among market participants. Reports suggest that liquidity in specific secondary segments has been challenged, partly influenced by the current cost of debt for necessary upgrades. Analysts suggest that monitoring this sector involves considering the impact of maintenance costs and evolving tenant requirements on long-term asset values.
Market participants continue to examine asset-specific metrics, as the current environment suggests that broad-market cap rate averages may not fully capture the distinct risks associated with secondary-grade office stock.
