The decision rule, and why it beats the rent-is-wasted-money instinct
Most owners arrive at this decision carrying one sentence: rent is money down the drain, a mortgage builds equity. The sentence is not wrong, but it is only a quarter of the picture, and buildings bought on that instinct alone are how good businesses end up cash-starved. Ownership concentrates a large share of your capital in one illiquid asset, loads a debt schedule onto the same cash flow that funds payroll and inventory, and trades the flexibility to move for the chance to capture appreciation. Whether that trade is brilliant or reckless depends on four questions, and the rest of this page works through them in order.
| The trade | Leasing | Buying |
|---|---|---|
| Cash at the start | Deposit and leaseholds; capital stays in the business | Down payment, land transfer tax, legal, inspections and reserves; a large permanent commitment |
| Monthly cost over time | Rent with scheduled escalations, plus operating costs in most commercial leases | Mortgage, property tax, insurance, maintenance and a capital reserve; the payment resets at each renewal |
| Flexibility | Move, shrink or expand at term end; exit cost is capped | Selling or leasing out is slow and transactional; wrong-sized space is expensive to fix |
| Who captures appreciation | The landlord | You, along with the risk of the reverse |
| Tax treatment | Rent is deductible as paid | Interest, operating costs and capital cost allowance on the building are deductible; the land is not depreciable and gains are taxed at sale |
| At retirement or sale | Nothing to show, nothing to manage | A rent-paying asset you can keep when the business sells, or sell separately |
Notice what the table does not contain: a winner. Leasing is not timid and buying is not automatically the grown-up move. They are different allocations of the same limited capital, and the honest comparison is run in dollars, after tax, over the period you will actually occupy the space. That comparison is a projection exercise, which is why the next step in a lease vs buy decision is accounting work before it is real estate work.
Question one: how long will this location actually serve the business?
Ownership needs a long occupancy to win, because the transaction costs at both ends are heavy. Buying carries land transfer tax, legal fees, inspections, financing costs and lender fees; selling carries commissions and more legal work; and in between, the early mortgage years are mostly interest. Spread across four or five years those costs usually erase whatever equity the period built. Spread across ten or fifteen, they fade into rounding. So the first honest question is not whether you like the building, it is whether the business you will be running in year eight still fits it.
Answer it with your growth plan, not your feelings about the neighbourhood. A business growing headcount or equipment at any real rate can outgrow a building the way a teenager outgrows shoes, and wrong-sized owned space punishes you twice: once in operations, once in the cost of unwinding it. Shrinking is just as dangerous, because a half-empty building you own is overhead with a mortgage. Ask what revenue looks like in five and ten years, what space that revenue needs, and whether this property can flex, spare land, dividable units, the ability to lease out a surplus bay.
Some businesses get a structural push toward owning: specialized fit-outs that no landlord wants to fund and no tenant improvement allowance covers, uses that landlords resist, or locations where the customer base is genuinely tied to the address. A machine shop with pits and cranes, a clinic with plumbing in every room, a food producer with regulated finishes: sinking that capital into a landlord's building on a five-year term is its own kind of risk, and it shifts the horizon math toward ownership even for a business that is still growing.
If the honest answer is that you cannot see past three or four years, stop here and lease, and revisit when the picture lengthens. A short, flexible lease while the business finds its shape is not wasted money. It is the cost of keeping your options open, and it is usually the cheapest insurance you will ever buy.
And if you stay on the lease path, negotiate it like the major financial commitment it is. Term length against renewal options, the escalation schedule, the tenant improvement allowance, who carries which operating costs, and your rights to sublet or assign all move real dollars, and a tenant with clean financial statements and a projection negotiates from strength. Most owners spend twenty times more effort on a purchase than on a lease of similar total value, which is exactly backwards for the business that should be leasing.
Question two: can the business carry ownership without starving itself?
The carrying test compares the full annual cost of owning, not the mortgage payment, against the cash flow the business reliably produces after paying you properly. Full cost means mortgage principal and interest, property tax, insurance, utilities, maintenance, and a reserve for the roof, the paving and the HVAC, because buildings spend your money in lumps. Lenders compress this into a debt service coverage ratio and want your cash flow comfortably above all debt payments, and they will test it on your historical statements, so the business has to already demonstrate the capacity, not merely project it.
Then look at the cash to close. Commercial purchases typically need a substantially larger down payment than residential buyers expect, plus Ontario land transfer tax, legal and inspection costs, and enough working capital left over that the business does not limp out of closing. HST applies on most commercial property purchases; an HST-registered corporation generally handles it through self-assessment on its return rather than writing a cheque at closing, but the mechanics have to be set up correctly in the agreement, and getting them wrong turns a paper entry into real money owed.
Two stress tests before you trust the answer. First, rerun the numbers at a meaningfully higher interest rate, because commercial mortgage terms are short, typically five years against a much longer amortization, and you will face at least one renewal at a rate nobody can promise you today. Second, rerun them on your weakest recent year rather than your best. If ownership only works at today's rate and last year's record revenue, the business cannot afford it yet, and a lease with a purchase mindset, keep banking cash, revisit in two years, is the honest conclusion.
This projection work is exactly what owners mean when they search for business financing and projections help from a CPA in Ontario, and it is the deliverable we build first in every lease vs buy engagement: both paths, monthly, after tax, stressed, on one page. The same file later becomes your lending package, so none of the work is thrown away, whichever way the decision goes. That continuity is the practical argument for running this through financing support rather than a spreadsheet built the night before a bank meeting.
Question three: what would the down payment earn inside the business instead?
Every dollar in a down payment is a dollar not funding inventory, equipment, people or acquisitions, so the real cost of buying is whatever that capital would have earned in the business. This is the question the rent-is-wasted instinct skips entirely, and it is where the answer most often flips. A distributor whose capital turns into margin several times a year, or a contractor whose working capital determines how many jobs run at once, may earn far more deploying that cash in operations than a building will ever appreciate. For businesses like that, leasing is not losing; it is renting the building so your capital can keep doing the higher-yield job. We see this constantly in our work with general contractors, where bonding and cash requirements already compete for every dollar.
The comparison runs the other way for businesses that throw off more cash than they can profitably reinvest. A mature practice or a steady service company with no acquisition appetite and full tax-sheltered accounts has capital looking for a home, and a building the business pays rent to is a legitimately good one: a real asset, a forced-savings discipline, and eventually an income stream that outlives the operating years. In that situation the opportunity cost of the down payment is low, and ownership's case strengthens accordingly.
Debt capacity is part of the same budget. Lenders underwrite your business as one credit, so a mortgage consumes borrowing room you might want next year for equipment or an acquisition, and the covenants that come with property debt, coverage ratios, reporting requirements, restrictions on further borrowing, constrain the whole company, not just the building. If a major equipment purchase is also on the horizon, sequence the two deliberately; we walk through that preparation in preparing for a major equipment financing decision, and the two files share most of their homework.
Question four: what does owning add at the end?
The strongest case for buying is usually the endgame, because a building is the one business asset that routinely outlives the business. Owners who buy sensibly in their forties often arrive at retirement with a paid-down property that either sells alongside the company, sells separately, or stays and pays rent for decades. A buyer of your business may not pay much for goodwill, but the real estate holds value independently, and keeping it while selling the operations converts your exit into an income stream instead of a single cheque. None of that exists on the lease path, which is precisely the trade you accept in exchange for flexibility and cheaper capital.
If the endgame is part of your reasoning, the ownership structure matters as much as the purchase, and it should be settled before the offer, not after. Most owners should not buy the building inside the operating company, because that ties the property to operating risk and complicates a future sale of the business; a separate corporation owning the property and leasing it to the opco at market rent is the common shape, with personal ownership occasionally winning in specific situations. The full comparison lives in who should own the property: you, the opco or a holdco, and the lender's security requirements will have their own opinion, so read it alongside the financing plan.
Be equally honest about what ownership adds during the years in between: a second job. You become your own landlord, with the roof, the tenants if you lease surplus space, the property tax appeals, the insurance renewals and the refinancing every few years at whatever rates then prevail. Some owners genuinely like that work and treat the building as a parallel investment they understand. Others discover they have bought a distraction. Neither reaction is wrong, but only one of them belongs in your building.
What to do next, and the facts that change the answer
The path from dealing with this decision to deciding it runs in six steps, in order. First, get your financial statements current and credible, because every later step reads from them; if they are behind, a compilation brings them to a standard a lender accepts. Second, build the two-path projection from questions one through three: lease as-is versus buy at realistic numbers, monthly, after tax, stressed for rate and revenue. Third, take the buy path to a lender for a real pre-read of your debt capacity, because an approval-in-principle turns your search from browsing into shopping. Fourth, settle the transaction structure, which entity buys, where the down payment comes from, how rent will flow, before an offer exists.
Fifth, if you proceed, do the due diligence a building deserves: an independent building condition assessment, an environmental assessment where the property's history suggests one, a review of zoning and permitted uses against your actual operations, property tax history, and any existing leases if the building comes with tenants. Sixth, negotiate the financing as a package, rate, term, amortization, covenants, reporting obligations and prepayment terms together, because the covenant you ignore at signing is the one you breach in year three. A lender who requires annual statements and a coverage test wants a borrower who saw that coming.
Ownership also signs you up for lender reporting as a permanent routine, and it is worth pricing that into the decision rather than discovering it. Expect to deliver year-end statements within a set deadline, sometimes interim statements, an annual covenant calculation, proof of insurance and property tax payments, and a rent roll if part of the building is tenanted. Businesses whose books close on time treat this as an email; businesses that scramble every year-end turn a routine requirement into an annual crisis, which is one more reason the statements come first in this sequence.
The facts that most often change the answer:
- Your honest horizon in the space. Under five years leans hard to lease; past ten, ownership starts winning on arithmetic.
- Coverage on your weakest recent year, not your best, because the mortgage does not take bad years off.
- What your capital earns in the business. High-return operators lease; cash-rich, low-reinvestment businesses buy.
- How specialized your space needs are, since heavy fit-outs shift the math toward owning.
- The local market's rent trajectory, because rapidly escalating rents shorten the payback on buying.
- Your exit plan, because a building you keep can fund the retirement the sale of a small business often cannot.
We run lease vs buy decisions as defined-scope work: the projection, the lender pre-read, the structure recommendation and the due diligence checklist, with a written scope and fee after a free 15-minute discovery call. If the decision resolves toward buying, the follow-on question of whether the corporation should be the buyer is covered in should my corporation buy commercial property, and the financing mechanics in the pages linked below pick up from there.
