Why Markham Deserves Its Own Underwriting Framework

Markham is not Brampton. It is not Mississauga. And investors who underwrite it like either of those markets tend to make costly assumptions.

York Region's largest city has built a distinct industrial identity over the past two decades — one shaped by its proximity to the Highway 407/404 interchange, its deep tech and life sciences employment base, and a tenant mix that skews toward precision manufacturing, last-mile distribution, and R&D-adjacent uses. That identity has real implications for how you model NOI, assess lease risk, and calibrate exit cap rates.

In 2026, with GTA industrial vacancy nudging upward from historic lows and interest rates still elevated relative to the 2010s, disciplined underwriting in Markham matters more than ever. Here's what experienced buyers and their brokers are actually looking at.

Markham Industrial Cap Rate Benchmarks: 2026

After the compression cycle of 2020–2022 pushed GTA industrial cap rates into the low-to-mid 3% range, the market has repriced meaningfully. In Markham specifically, stabilized industrial assets are trading in the 4.75%–5.75% range as of mid-2026, with meaningful dispersion based on a handful of key variables:

Building vintage and clear height: Modern 28–32 ft clear product commands tighter cap rates than 1980s-era 18–22 ft buildings.
Lease term remaining: A 7-year lease with a creditworthy tenant trades at a meaningfully tighter cap than a 2-year rollover risk.
Unit size and configuration: Smaller multi-tenant flex bays (5,000–15,000 SF) often trade at wider caps due to higher management intensity and rollover frequency.
Tenant covenant: A publicly traded tech manufacturer anchoring a building is underwritten very differently than a small owner-operated distribution company.

For value-add plays — buildings with near-term lease expiries, functional obsolescence, or deferred capital — buyers are underwriting to 6.0%–7.0%+ going-in yields to justify repositioning risk and carrying costs during transition.

NOI Construction: What to Get Right in Markham

Net Operating Income analysis is where deals get won or lost at the underwriting table. In Markham, there are a few line items that deserve more scrutiny than a generic GTA model might apply.

Net Rent vs. Market

Markham industrial net rents peaked in the $18–$22 PSF range for functional modern product in 2022–2023. In 2026, effective net rents for new leases on comparable product have settled in the $15–$19 PSF range, with landlords offering modest TI packages and free rent periods that were largely absent two years ago. If your pro forma assumes in-place rents mark to market at lease expiry using 2022 comps, you're building in a loss.

Underwrite renewal rents conservatively. Model flat-to-modest rent growth (1%–2% annually) unless you have a specific catalyst.

TMI and CAM Recovery

Markham's industrial TMI (taxes, maintenance, insurance) typically runs $4.50–$6.50 PSF depending on property age and assessment. Older buildings with deferred capital often carry higher maintenance line items that erode gross-to-net spreads. Verify what's actually triple-net recoverable under existing leases versus what the landlord is absorbing — this distinction matters enormously on smaller multi-tenant properties with older lease templates.

Vacancy and Credit Loss

Markham's industrial vacancy rate sits in the 3.5%–5.5% range as of 2026 — up from sub-2% in 2022 but still historically tight by any reasonable measure. That said, vacancy is not evenly distributed. Older flex-industrial product in the Woodbine/14th Avenue corridor and some of the mid-1990s parks along Denison Street have seen longer re-leasing timelines.

Underwrite a 5%–7% stabilized vacancy/credit loss assumption for multi-tenant properties. For single-tenant buildings with strong covenant and long-term leases, 2%–3% is defensible.

Markham's Industrial Corridors: Not All Nodes Are Equal

Markham's industrial inventory is not monolithic. The market breaks down into several distinct nodes, each with its own rent, vacancy, and tenant profile dynamics.

Highway 407 / Woodbine Corridor

This is Markham's premier industrial address. Modern big-bay distribution product, strong 407 access, and proximity to the CP intermodal facility in nearby Vaughan make this corridor attractive to regional logistics operators. Rents and cap rates here are at the tighter end of the Markham range.

Warden / Steeles / Kennedy Nodes

Older, denser industrial fabric with a mix of small-bay multi-tenant and mid-size single-tenant buildings. Tenants here lean heavily toward light manufacturing, auto-adjacent trades, and service industrial. Functional obsolescence is more common — 18–22 ft clears, limited truck courts, surface loading. Underwrite with wider cap rates and more conservative re-leasing assumptions.

Markham Road / 16th Avenue Area

A transitional zone with a mix of industrial, flex, and some commercial uses. Zoning complexity is higher here, and investors need to verify permitted uses carefully before underwriting repositioning scenarios.

Financing and Yield-on-Cost Reality Check

With CMHC-insured industrial financing rates in the 4.75%–5.50% range (5-year term, depending on amortization and LTV) and conventional lenders pricing similarly, the math on levered returns has compressed substantially from the 2020–2021 era.

On a typical Markham stabilized acquisition at a 5.25% cap:

Purchase price: $10,000,000
NOI: $525,000
Debt service (65% LTV, 5.10% rate, 25-year am): ~$380,000
Pre-tax cash-on-cash: ~$145,000 / $3,500,000 equity = ~4.1%

That's not a bad return in isolation, but it leaves little margin for error. Vacancy, capex surprises, or a lease renewal at below-market rents can quickly compress cash flow to uncomfortable levels.

The deals that pencil well in 2026 are those where buyers can identify a credible value-add angle — a below-market lease with near-term expiry, functional improvements that justify a rent step-up, or a repositioning from single to multi-tenant — and underwrite the transition period honestly.

What Smart Buyers Are Watching in Markham Right Now

New supply pipeline: Markham has limited greenfield industrial land compared to western GTA nodes. Most new supply is coming via intensification and redevelopment rather than large-format new builds. This structural supply constraint is a medium-term positive for existing inventory.

Life sciences and tech hardware demand: Markham's positioning as a hub for companies like AMD, Honeywell, and a dense cluster of med-tech firms creates durable demand for functional flex-industrial space. This tenant base is less rate-sensitive than pure logistics operators, which provides some insulation from broader e-commerce demand fluctuations.

York Region intensification pressure: Some older industrial nodes are facing rezoning pressure for mixed-use or employment area conversion. Investors need to assess whether this creates an exit optionality premium or a risk to industrial use continuity. Check with the City of Markham's planning department before underwriting any redevelopment thesis.

The Underwriting Discipline That Separates Good Deals from Bad Ones

Markham industrial real estate in 2026 rewards buyers who do the work: verifying lease abstracts, stress-testing rent assumptions, pressure-testing TMI recovery language, and modeling realistic re-leasing timelines. The days of buying anything industrial at any price and being bailed out by cap rate compression are behind us — at least for this cycle.

The fundamentals here remain sound. York Region's employment base, constrained land supply, and 407/404 infrastructure access make Markham a market worth underwriting carefully. Just make sure your model reflects 2026 reality, not 2022 nostalgia.
