Office Building — Markham
Valuing a Dual-Faceted Asset: Navigating Complex Highest & Best Use for a Class A Office and Mixed-Use Redevelopment Site in Markham

Property & Assignment Overview
The Asset: We were tasked with evaluating a prominent 10-storey, Class A suburban office property situated in a premier transit corridor in Markham, Ontario. The building comprises over 160,000+ square feet of net rentable area and is anchored by a major national financial institution. Notably, the structure sits on a large ~6.0-acre site, which includes ~4.0 acres currently utilized as surface parking.
The Mission: The client, an institutional property owner, required a CUSPAP-compliant opinion of the Fee Simple interest's current market value on an all-cash basis. The authorized use of the appraisal was to secure First Mortgage Financing.
The Challenge
This assignment presented a layered valuation challenge that required looking beyond the property's current utility:
- Divergent Asset Components: The property functioned adequately as a stabilized commercial asset, yet the ~4.0 acres of surplus surface parking represented a underutilization of a prime land parcel.
- Complex Highest and Best Use (HBU): While the current employment zoning strictly controls retail and explicitly prohibits residential development, our highest and best use analysis concluded that the existing purely commercial use is obsolete for this site. The true maximally productive use is a high-density, multi-tower mixed-use development featuring retail, hotel, and residential components.
- Financial Stabilization Nuances: The existing office rent roll featured below-market in-place rents and meaningful vacancy rates. Valuing the income stream accurately required mark-to-market forecasting and the calculation of substantial stabilization costs, including leasing commissions and tenant improvements.
Our Approach & Expertise
To capture the asset's true market value, we applied a highly transparent “Sum of the Parts” methodology. This ensured the current financial yield of the office building was accurately measured without being mathematically skewed by the non-income-producing surplus land.
- Bifurcated Valuation Strategy: We treated the property as two distinct economic components. For the office building, we utilized the Income Approach via the Direct Capitalization Method, relying on comprehensive market rent surveys to stabilize the Proforma. For the surplus land, we executed a Direct Comparison Approach, isolating the ~4.0 acres and comparing it against recent high-density land acquisitions in the region.
- Deep-Dive Market Analytics: Our team analyzed extensive submarket data, noting a “Flight to Quality” trend in the Greater Toronto Area (GTA) office sector and calculating a risk-adjusted capitalization rate.
- Local Zoning & Planning Foresight: Leveraging our deep understanding of Markham's official plan and the specific dynamics of the Highway 404/407/7 transit interchange, we applied a hypothetical condition to value the surplus land based on its future mixed-use densification potential, independent of the current office operations.
The Outcome
By separating the property's operational cash flow from its intrinsic redevelopment potential, we delivered a rigorously researched and defensible valuation report. The final appraisal concluded a highly accurate market value that reflected both the stabilized office asset and the premium of the surplus land.
This comprehensive analysis empowered our client to successfully proceed with their financing requirements, providing their stakeholders and lenders with total clarity on the asset's current performance and its massive future development horizon.
