Short Term Rental Income and the Off Season

A cottage, a ski condominium, a downtown unit rented by the week. The money arrives in bursts, and the money leaves evenly. The mortgage does not know it is February, the property tax does not pause in the shoulder season, and the insurance renews on its own date. Every cost in the building runs on a calendar, and only the revenue runs on a season.

That mismatch, and not the gross revenue, is the thing to plan around. This page sets out how the gap is carried, what figure every commitment should be sized against, and what a lender is likely to make of the income. None of it is complicated, and all of it has to be decided before the first strong summer arrives.

What is the actual shape of the problem?

Income concentrated into a few months against costs spread across twelve. That sentence is the whole business model stated as a problem.

Take a property that earns most of its annual revenue between June and September, or between December and March if it is a ski market. The peak is large. The off season may be nothing at all, or enough to cover utilities and no more. Meanwhile the mortgage payment arrives twelve times, the property tax is due whether or not anyone stayed, the insurance renews annually, and in a condominium the common expenses run monthly regardless. The building has no idea which month it is, and the bills reflect that. A shoulder season that produces almost nothing is normal and not a failure.

The consequence is a cash flow problem and not a profitability problem, and the two are handled differently. A property can be genuinely profitable across a year and still leave its owner short in March. Lenders, accountants and owners all understand this in principle and it is the owners who are caught by it, because the shortage arrives eight months after the money did. Profit and liquidity are different questions, and February only asks the second one.

The correction is not to earn more in the peak. It is to move money forward in time, deliberately, the week it arrives. Moving money forward is the only tool that addresses the mismatch directly.

What is the durable figure?

The monthly income the property produces in a poor year, and not a good one. Good years make poor planning assumptions, and everybody uses them anyway.

Every seasonal owner has two numbers in their head: what the property made last year, which was strong, and what it made the year the weather was bad or the border was awkward or the market softened. The second number is the one that should govern every commitment, because commitments are monthly and permanent while income is seasonal and variable. Commitments do not know about seasons, and they arrive on the first of every month. Both numbers are real, and only one of them is safe to build on.

Arriving at it is arithmetic and not judgement. Take the three most recent full years. Choose the worst of them. Divide by twelve. That figure is what the property reliably produces per month, and it is normally a good deal smaller than the impression left by a strong August. The arithmetic takes ten minutes and the discipline takes years.

Everything sized against it is safe. The mortgage you can carry, the premium you can commit to, the renovation you can finance, the reserve you have to hold: all of them are decided by the durable figure. Sizing anything against the peak produces an owner who is comfortable for four months and stretched for eight, and that pattern is what forces sales. Sizing to the peak is the single decision that ends most seasonal operations.

How is the off season funded?

By a fixed transfer out of every peak deposit, made the week the money arrives. The transfer is the mechanism; everything else on this page is the reasoning behind it.

The calculation is short. Add the twelve months of fixed costs: mortgage, property tax, insurance, common expenses, base utilities, any management contract. Subtract whatever the off season itself brings in. The difference is the shortfall the peak has to cover. Divide it by the number of peak months and you have the amount that must move across every month of the season. Do the calculation once, write it on the account, and stop revisiting it.

Convert that into a percentage of peak revenue, set up the transfer, and let it run automatically. The account it moves into is separate, at a different institution, and is not the account the business operates from. Automation removes the monthly argument with yourself, which is the point of it.

The timing is the part owners get wrong. A transfer made at the end of the season, out of what is left, is made out of whatever survived the summer, and a strong summer feels like a surplus and not like a float for a winter that has not arrived yet. Money moved the same week it lands is money that never became available for anything else. Money that never becomes available is money that is still there in March. Owners who automate this never think about it again, which is the entire benefit.

What does a lender make of this income?

Less of it than the owner does, and the variation between lenders is wide enough that the question has to be asked and not assumed. That variation is itself the finding, and it should change how you plan a purchase.

Some lenders will not count short term rental income in a mortgage application at all, and will underwrite on the borrower's employment or business income instead. Some count a portion of it, supported by two years of filed tax returns and not by statements from a booking platform. Others apply a discount to a documented figure. All of that is lender policy, it differs between institutions, and it changes. Policies differ so much that a general answer is worse than no answer. Two years of filed returns carry more weight with an underwriter than any platform report.

Three factors drive the caution. The income is variable and not contractual, because there is no lease. The regulatory position of short term rentals has moved in many Canadian municipalities and can move again. And the property's value as security may be assessed on its conventional long term rental performance and not on its short term revenue. None of those three reasons is unreasonable, and together they set the discount.

The practical instruction is to ask a mortgage broker how the specific lenders they work with treat this income before you build a purchase around it. An investor who assumes the revenue counts and discovers at underwriting that it does not has lost a deposit and a month. Ask before the offer, not during the conditions period.

What does the regulation risk look like?

Real, local, and capable of changing the economics of the property between one year and the next. It is the one exposure on this page that you do not control at all.

Short term rental rules in Canada are set at the municipal level and sometimes at the provincial level, and they have tightened in many markets. Registration requirements, primary residence conditions, limits on the number of nights, zoning restrictions and outright prohibitions in some buildings and districts all exist somewhere. A condominium's declaration of co-ownership can also prohibit short term rental regardless of what the municipality allows. Rules that were relaxed in one municipal term can tighten in the next. A declaration of co-ownership can end the business on its own, without any municipal involvement.

This is not a reason to avoid the business. It is a reason to underwrite the property twice: once on the short term numbers, and once on what it would produce as a conventional long term rental. If the property is only solvent on the short term numbers, the owner is carrying regulatory risk on the whole position and not on the upside. Underwriting the property twice costs an afternoon and removes most of the risk of surprise.

Read the declaration of co-ownership before buying into a building. Check the municipal register and the by-law rather than relying on what the seller says other owners are doing. And ask what happens to the financing if the permitted use changes, because that question belongs to the lender and not to you. Three documents and one phone call cover almost all of it.

What about tax and the commodity taxes?

Short term accommodation is treated differently from long term residential rent, and the difference surprises people the first year. The first year is when the rules are learned, and it is the most expensive year to learn them in.

Long term residential rent is generally exempt from GST and HST. Short term accommodation is generally taxable, which means an operator whose revenue passes the registration threshold may be required to register, charge and remit. Booking platforms handle part of this in some provinces and not in others, and the operator's own obligation does not disappear because a platform collected something. Registration thresholds and platform practices both change, so verify them in the year you operate. Platforms collect in some provinces and not in others, and the operator remains responsible either way.

There is a second consequence that arrives later. Changing a property's use, for example from personal use to a commercial short term operation or back again, can trigger a change in use for tax purposes with its own effects. So can the question of whether the activity is a rental of property or the operation of a business, which affects how expenses are treated and in some cases how income is characterised. Characterisation questions are answered on facts and not on labels.

None of this is tax advice and the practice does not give tax advice. It is a list of the questions to bring to a CPA before the first season and not after the first filing. A first season run without asking these questions is a first filing spent answering them.

Where does a participating contract fit?

Only where the premium is sized to the durable figure, and that condition is not a detail. Everything depends on that one design choice being made correctly at issue.

A participating whole life contract requires premiums, on a schedule, for a very long time. Irregular income funding a fixed obligation is the commonest way a contract lapses in year four, and a lapsed contract in year four has collected all the early costs and delivered none of the later value. That is the worst outcome available in this subject and it is entirely avoidable. A contract abandoned early is worse than a contract never started.

The way to avoid it is a design decision made before the contract is issued. A smaller required premium, set at a level the durable figure can meet in a poor year, with an optional additional deposit used in strong years where the contract allows it. The good season adds and the bad season breaks nothing. The availability of that structure and its cost depend on the insurer, which makes it a question for the proposal stage. Ask for both versions of the proposal and compare them side by side.

The accumulated value, once it exists, has a specific use in a seasonal business: it is capital that can be drawn on by policy loan without a credit decision, in a February when the season was poor and the lender is unenthusiastic. That is a narrow use and a real one. Where the other places capital can wait stand on their attributes is set out in where capital waits between properties.

What should the reserve look like here?

Larger than a long term landlord's, and calculated on a different basis. Seasonal reserves are bigger because seasonal risk is longer, not because it is more likely.

A conventional landlord sizes a reserve against a vacancy and a repair. A seasonal owner has to size it against a bad season, which is a longer event. One poor summer does not end in a month; it produces a shortfall that runs until the next peak, which may be nine months away. A season is a longer event than a vacancy, and the reserve has to span it. Nine months is a long time to be short, and it is the ordinary shape of a bad season.

The working method is to hold the off season shortfall in full, plus the ordinary repair reserve on top of it. That sounds heavy and it is the price of an income pattern that concentrates risk into a short window. Owners who hold less are relying on the next season being normal, which it usually is and occasionally is not. Most owners hold less than this, and most years that is fine.

The same reserve discipline described in the vacancy and the repair applies here, with the numbers moved up. And the turnover costs of a short term operation are higher per dollar of revenue than a long term tenancy, because the cleaning, the linen, the consumables and the wear all repeat weekly and not annually.

Who this suits, and who it does not

It suits an owner whose household income does not depend on the property, because the seasonal pattern is then an inconvenience and not a threat. The pattern is manageable; being surprised by it is not.

It suits an owner who has run the property for at least three years and therefore knows what a poor year looks like from experience rather than from a projection. Three years of records beat any projection ever prepared.

It suits an owner who has read the municipal rules and the declaration of co-ownership, and who can state what the property would earn as a conventional long term rental if the permitted use changed. A property that also works as a long term rental is a property with a second plan.

It does not suit an owner who bought on peak season projections and is carrying a mortgage sized against them. It does not suit an owner with no reserve, because the seasonal pattern guarantees a shortfall window every year and a reserve is the only thing that spans it. And it does not suit an owner looking to fund a contract out of a strong season, because a contract funded on a peak and abandoned in a trough delivers the worst of both. Knowing the long term rental number is what makes the rest of the plan defensible.

The arrangement as a whole is described on the real estate investors page, and the limits of the strategy for an investor are collected in what a policy loan cannot do for an investor.
