Selling Your Plex to Rent a Condo in Retirement: The Real Trade-Off

It comes up regularly among plex owners approaching retirement: sell the building, take the proceeds, and rent a condo instead. It is almost always framed as a question about the sale price. It is not one. On the tax side of the disposition itself, see our dedicated piece on tax optimization when selling a plex in Quebec.

What this decision is not

One confusion has to be cleared first, because it changes the whole method. An owner weighing whether to keep or sell is comparing two states of a single asset. Under either outcome they still own something: the building, or the proceeds from it. We covered that case for condos in our piece on the rent-or-sell decision for condo owners.

The decision examined here is of a different kind. It involves a change of tenure: you stop being an owner and become a tenant. Three things shift at once. The estate changes form, from a building into financial capital. Income changes nature, from rent collected into a return that has to be produced. And an obligation appears where there was none: paying rent every month, for life. Any calculation that surfaces only the first of those three is incomplete.

Two segments rising at different speeds

Data published by APCIQ on September 4, 2026 for the Montreal census metropolitan area sets the scene. Year over year, the median plex price is up 2% and the median condo price up 4%. Plex selling time stands at 52 days, four fewer than a year earlier: the segment is not clogging up.

Those figures help provided you do not stretch them. They do not describe your building or the condo you would target: they are regional medians. What they indicate is the direction of the current. Over that period, condos are appreciating slightly faster than plexes. For someone planning to sell one and rent the other, that bears on the rental market at the destination rather than on the price received, and we return to that point below.

What the sale triggers that a price ignores

The listed and then negotiated price is a gross amount. Between that amount and what is actually available to live on, two tax effects sit in the way. Both need to be quantified separately, with a tax specialist, before anything is decided.

The first is the capital gain on the rental portion of the building. An owner-occupied plex is not treated as one homogeneous block: the part you live in and the part you rent out do not necessarily fall under the same rules. The split applied over the years therefore carries consequences on closing day.

The second is depreciation recapture. An owner who claimed capital cost allowance on the building for years reduced taxable income accordingly. The disposition can bring part of those deductions back into income in the year of the sale. That amount often takes people by surprise, because it corresponds to no visible cash outflow and appears in no valuation.

We are not putting rates or amounts on either here: both depend on filing history, on the split between the occupied and rented portions, and on the seller's personal situation. What does hold without exception is the method: these two items get calculated before anything is compared, not after a choice has been made.

What disappears on both sides of the ledger

Selling removes income and costs at the same time, and both columns deserve the same rigour. On the income side, rent collected disappears, net of actual vacancy and actual arrears, not the theoretical rent written into the leases.

On the cost side, property taxes and building insurance disappear, along with reserves for major work, routine maintenance, and above all management time. That last item is almost always left out because it never leaves a bank account: tenant searches, coordinating repairs, handling arrears and legal recourse. Value it, at minimum in hours. A ledger that ignores it is systematically biased toward staying put, which is no help in deciding.

The rent you pay is not indexed to the price you receive

This is the least understood point and the heaviest over a twenty-year horizon. The sale price is set once, on a date, and then it is fixed. The rent you pay as a tenant keeps moving with the rental market and the applicable legal framework, with no link whatsoever to what you received for the building.

Put differently, the protection a good sale buys you is bounded. Selling well improves the starting capital; it does nothing to soften later rent increases. An owner who stays is exposed to maintenance and vacancy; the tenant they become is exposed to the rental market. Those are not the same exposure, they do not behave the same way, and trading one for the other is precisely the decision at hand.

The method: five lines before you decide

The trade-off states cleanly in five written lines, using your own numbers. One, net proceeds of disposition: negotiated price less selling costs less the two tax effects above. Two, the annual income that net capital would produce, on a return assumption you choose and write down so you can vary it.

Three, the annual rent you would pay, including charges. Four, the current net rental income of the plex, after real costs and after valuing management time. Five, compare line two minus line three against line four. Then vary one assumption at a time, starting with rent over ten and twenty years, since that is the term that is not fixed. A decision that survives several rent scenarios is sound. One that only works under the most favourable is a bet, and a bet on where you live in retirement deserves to be named as such.
