Why cap rate is the only number commercial buyers really look at

In residential real estate, buyers care about square footage, finishes, and school catchments. In commercial real estate, buyers care about one number: cap rate. The capitalization rate is what tells an investor whether a $4 million plaza is actually worth $4 million or worth $3.2 million. It is calculated by dividing the property’s net operating income by the asking price. A 6% cap rate means an investor earns 6% per year on the purchase price before financing. Lower cap rate equals more expensive property relative to its income. Higher cap rate equals cheaper. The GTA commercial market in 2026 runs roughly 3.5-4.5% for prime multi-residential, 5.5-7.5% for retail plazas, and 6.5-8.5% for office buildings. Outside those ranges, the deal is either too good to be true or pricing in something the seller is not disclosing.

What this calculator catches that brokers won’t tell you

Listing brokers present cap rates calculated with optimistic assumptions — full occupancy, no vacancy allowance, minimal management costs, the rental rates they hope to achieve rather than the rates currently in the lease. This calculator forces you to enter the actual numbers. The vacancy allowance defaults to 5% because that is the GTA realistic average. Property management defaults to 5% because that is what most third-party managers charge. Repairs and maintenance default to 5% because that is what older GTA commercial properties actually cost to operate. If your broker’s pro forma shows zero vacancy, zero management cost, and zero maintenance — they are showing you the seller’s wish list, not your future P&L. This calculator gives you the real number.

When to call Alex

If the calculator shows your target property at a cap rate outside the comparable range for its asset class and submarket, there is a story behind that gap. It might be a structural issue with the building. It might be a below-market lease that expires in 14 months and resets to market rate. It might be a development opportunity the seller hasn’t capitalized in the price. Or it might be a desperate seller. Each of these gaps tells a different story about what the property is actually worth and what your negotiating leverage is. Book a 30-minute commercial walkthrough — I will tell you which story you are looking at and what the right offer price is given the cap rate gap and the GTA submarket context. No pitch, no listing presentation — just the cap rate analysis you can’t get from a listing broker.
