How do you evaluate whether the business can actually afford commercial property?

Step one: establish the cash flow the business actually produces

Affordability starts with normalized cash flow, not the profit line on last year's statements. Take two or three years of financial statements and strip out what will not repeat: one-time gains, an unusually good contract, COVID-era anomalies if they still linger in your comparatives, and any expense that exists because of you rather than the business. Then charge the business a fair wage for your own work, even if you actually pay yourself in dividends, because a building cannot be financed out of your unpaid labour.

Cash flow and profit part ways in two places you must respect. First, tax: the cash available for a mortgage is what remains after corporate tax, not before it. Second, working capital: a growing business consumes cash in receivables and inventory even in profitable years, and that consumption continues after you buy a building. If receivables stretch when a big customer slows down, the mortgage payment does not wait for them.

Be honest about which year you are measuring. A lender will average or take the weaker of recent years precisely because owners anchor on the best one. If the last twelve months are the outlier, the affordability question is whether the ordinary years carry the building, and the answer has to come from your own numbers, not from optimism about repeating the record.

Step two: price the true cost of owning, not the mortgage payment

The cost of owning is the mortgage payment plus everything your landlord currently absorbs, and owners routinely underestimate the second half. Build the full annual figure before comparing anything to rent:

• Debt service: principal and interest at today's rate, and again at a stressed rate for the renewal test below.
• Property tax on a commercial assessment, which can move independently of your business.
• Insurance for the building itself, on top of the contents and liability coverage you already carry.
• Repairs and maintenance: snow, roof patches, parking lot, HVAC servicing, the items that used to be a phone call to the landlord.
• A capital reserve for the roof, furnace or paving job that arrives eventually, funded monthly rather than discovered suddenly.
• Utilities and common costs you may have paid through your lease, restated at owner scale.

Now set the comparison up fairly. Against that total, credit the rent you stop paying, adjusted for space differences and for the escalations built into your current lease, since staying put is not free either. The honest comparison is total cost of ownership against total cost of leasing over the same horizon, and the worksheet below is the shape we build it in.

Step three: run the coverage test the lender will run

Lenders decide affordability with a debt service coverage ratio: normalized cash flow available for payments, divided by the proposed annual debt service. Most commercial lenders look for coverage comfortably above one, often around 1.2 times or better depending on the lender and the asset, and they compute it on normalized numbers, not on your best year and not on projections alone. If your own math cannot clear their bar with room to spare, the purchase is marginal even if someone approves it.

Understand the term-versus-amortization gap, because it is where affordability quietly breaks. Commercial mortgages amortize over a long period but the rate is typically committed for a much shorter term, so the payment you are testing today is guaranteed only until the first renewal. Re-run the coverage ratio at a rate meaningfully above today's and ask whether the business still clears it; that renewal-rate test is the single most important line in the whole exercise.

Expect the coverage test to follow you after closing as a covenant. The commitment letter will usually require annual financial statements and a minimum coverage ratio tested on them, which makes lender reporting a permanent feature of ownership, not a one-time application hurdle. Budget for statements prepared to the standard the lender names, on the lender's timetable, every year of the mortgage.

Step four: count the cash to close, and what it costs to mobilize

Affordability is also a one-day cash question, because lenders finance most of the price but rarely all of it. Plan for a down payment somewhere between a fifth and a third of the purchase price on owner-occupied property, varying with lender and asset quality, plus closing costs that arrive in cash: Ontario land transfer tax, the municipal layer on Toronto property, legal fees, appraisal, a Phase I environmental report and lender fees. HST on a commercial purchase is usually a paperwork event rather than a cash event, since a registered purchaser self-assesses and offsets it in the same return, but that only works when the purchasing entity and its registration are lined up in advance.

Where the down payment comes from has its own tax price. Cash already inside the corporation can buy the building at no personal tax cost, which is a major reason the purchase usually belongs in a company, a decision we work through in should my corporation buy commercial property. Pulling corporate cash out to buy personally means paying personal tax first, shrinking your down payment before it touches the property.

Which company should take title is the other half of transaction structure, and the lender will have opinions about it that deserve scrutiny rather than automatic agreement. The interaction between the bank's preferred borrower and your tax position is its own decision, covered in how financing affects commercial property ownership structure. Decide it before the term sheet is signed, because changing title later costs land transfer tax again.

Step five: stress the plan before the bank does

A purchase the business can afford survives three bad scenarios at once, so test them on paper while walking away is still free. Push the renewal rate up materially and confirm coverage holds. Cut revenue to your weakest recent year and confirm the payments still clear. Then assume the building demands a real capital outlay in the first thirty months, because inspection reports soften what ownership makes vivid, and confirm the buffer absorbs it. Building-condition and environmental due diligence exist precisely to make this scenario concrete before closing rather than after.

Two quieter risks belong in the same review. Concentration: after closing, the building may be the largest asset you own, financed by the same business that pays for it and parked in the same local economy, so a downturn hits your income and your asset together. And opportunity cost: the down payment is capital that could otherwise fund equipment, hiring or an acquisition, and a building that returns less than the business itself is an expensive place to store money. If surplus space is part of the plan, treat tenant income as a bonus in year one, not a pillar, because vacancy is not something you control.

None of this argues against buying. It argues for buying with numbers that survive contact with a credit committee and a rate cycle, which is what affordability actually means.

The facts that change the answer

Six facts move this decision more than any spreadsheet formatting ever will:

• Normalized cash flow after fair owner pay. The engine. If it only covers the payments before you take a wage, the business is buying the building with your salary.
• The gap between current rent and full ownership cost. A small gap makes the decision strategic; a large one makes it financial, in either direction.
• The renewal-rate test. Coverage that survives a materially higher rate is affordability; coverage that only works at today's rate is timing luck.
• The source of the down payment. Corporate cash buys more building than the same cash after personal tax.
• The post-close buffer. Months of operating expenses left in the company after closing day, counted honestly.
• Revenue durability. Contracted, recurring or diversified revenue carries debt; concentrated or cyclical revenue needs a bigger cushion.
