Most owners can quote what their building would sell for. Fewer can quote what keeping it will cost.
Written for owners twenty or thirty years into a building. The arithmetic of the next five years of ownership, the actual net of an exit, and a third option most conversations skip — laid out so you can run the numbers yourself.
You have owned the building long enough that it mostly runs. The mortgage is small or gone, the tenants are long, and the income arrives whether or not you think about it. Which is exactly why the hold-or-sell question is hard to see clearly: nothing about the building forces the question, and most of the people raising it are paid on one side of the answer.
Including us. A brokerage earns its fee when buildings trade — which is precisely why the only version of this decision worth trusting is the one you can price yourself, on both sides. This page lays out both prices. It does not tell you which to choose, because that answer lives in your rent roll, your capital plan, and your family — not in anyone’s marketing.
The hold has a price now
Holding used to be close to free for a long-tenured owner: a paid-down mortgage, familiar expenses, rents that drifted up. Several of those inputs have repriced, and each belongs in the hold’s underwriting as a line item, not a mood.
Premiums on multi-residential buildings repriced hard between 2019 and 2024 — Ontario owners have watched the line roughly double over the past decade, and even U.S. Federal Reserve data puts multifamily insurance costs up more than 75% in real terms over just five of those years. Renewals have cooled recently as the commercial market softened — but nobody is refunding the repricing. The line item settled at a permanently higher base, and on an older building it is no longer a rounding line.
About 60% of Canadian mortgages renew by the end of 2026 (Bank of Canada), and money locked in at the 2020–21 lows resets at today’s rates. Commercial multi-residential carries the same five-year clock: a charge registered in 2020 or 2021 matures now. An owner who financed at the lows is, at renewal, buying today’s debt at today’s price — whatever the original spreadsheet said.
A 1970s building keeps 1970s appointments. Roofs, boilers, windows, plumbing stacks, balconies, electrical — the systems age on their own schedule, several of them land six figures at a time, and none of them care that the mortgage is paid off. The question is not whether these bills arrive but whose ownership they arrive in.
Record apartment completions in 2025 pushed purpose-built vacancy up, and near-term conditions favour tenants in many markets — which shows up for an owner as slower lease-ups and softer renewal leverage. Forward construction starts are falling, so this is a phase, not a permanent state; but the next few years of holding include it.
Ontario’s tenancy framework applies to every unit you own, and more tenancies mean more potential contact with it. Professional management changes the severity and cost of each incident — not the number of doors that can generate one.
None of these is an argument to sell. Each is a number, and numbers belong in a ledger, not a sales letter.
Holding is a purchase
Here is the frame that makes the decision tractable: every year you hold, you are choosing to buy the building again — at today’s value, with your equity, at today’s insurance, today’s debt, and today’s place in the capital cycle.
So ask the question in that form. If the building came to market today at its current value, with its current rent roll and its coming capital plan — would you be a buyer? If the answer is yes, hold with a clear conscience; the same arithmetic that would price a sale is telling you the hold earns its keep. If you hesitate, the hesitation has a number, and it is worth finding before the decision gets made for you by a boiler, a renewal date, or an estate.
The exit has a toll
Selling is not converting a building into its price. Canada has no equivalent of the American 1031 exchange — there is no rolling a sale into the next property untaxed. The proceeds pass through a toll booth, and the toll has three gates:
Every dollar of capital cost allowance claimed over the decades comes back as ordinary income in the year of sale. A long, well-advised hold usually means a low UCC — which is exactly what makes the recapture large.
The lift above your original cost is a capital gain, half of it taxable at your rate (50% inclusion — the proposed increase was cancelled and never took effect).
Selling costs, mortgage payout and any penalty, legal.
A building bought decades ago for $1.2M, ground down to a $700K UCC, selling at $3.0M: roughly $500K returns as recaptured income, $1.8M is capital gain with $900K taxable, and costs of sale stack on top — the gap between price and net routinely lands in the hundreds of thousands. The exact figure is knowable in advance: the Disposition Proceeds Calculator on this site walks price to net — selling costs, payout, penalty, recapture, and gains — at your numbers, with nothing gated.
Two things follow. First, your accountant should see your UCC position before you form a price expectation — not after an offer arrives. Second, structure is set before listing or not at all: share versus asset sale, entity questions, and timing can move the net materially, and they are decisions for your accountant and lawyer with the brokerage working alongside — never the other way around.
What preparation is worth
If the ledger does point to a sale — this year or in five — the difference between a well-prepared and a poorly-prepared disposition can be hundreds of thousands of dollars, and almost none of it is marketing polish.
Buyers pay for what they can underwrite. A documented gap between in-place and market rents is value a buyer’s lender can see; an undocumented one is a story. Normalized operating expenses let a buyer bid the building instead of padding for uncertainty. An assembled capital history — what was done, when, what remains — shrinks the diligence discount. Preparation is not staging; it is making the income legible, because the income is the price.
The option between hold and sell
One more branch, named because most conversations skip it: transition. Some buildings should pass to the next generation rather than to the market — and that path has its own structuring questions (timing, entities, estate mechanics) that reward the same early advisory work as a sale. Our own family has moved buildings between generations across three of them; it is why we will not tell you that selling is always the answer. Sometimes the right buyer shares your last name.

What we bring to an owner weighing this is not a pitch — it is the underwriting. A confidential valuation built the way a buyer’s lender would build it; the loss-to-lease and expense work that makes the building legible; and, if the ledger points to a sale, marketing to a buyer pool that already owns comparable buildings in comparable markets. Three generations of this family have owned, financed, and brokered Ontario multi-family; the fee only ever attaches to the last part.
