How Vacancy Affects Apartment Building Value in Ontario: NOI, Turnover and Rent Rules

Vacancy affects apartment building value because every vacant suite is income the building does not collect, and buyers capitalize that lost income into a lower price. But buyers look beyond the current occupancy figure. They ask why suites are vacant, how long they take to re-let, what rents new tenants will actually pay, and what it costs to turn a suite over. This guide is for Ontario owners preparing to sell a multi-residential building and for investors underwriting one. It explains the types of vacancy, how vacancy flows into net operating income (NOI) and value, how Ontario’s rent rules change what vacancy means, and how to present vacancy honestly to buyers.

Types of Vacancy Buyers Distinguish

• Physical vacancy: suites that are actually empty at a point in time.
• Economic vacancy: total income lost, including physical vacancy plus rent lost to arrears, bad debt, concessions and units held off the market for renovation or use by the owner.
• Frictional (turnover) vacancy: the normal gap between one tenant leaving and the next moving in. Even a well-run building has some.
• Structural vacancy: suites that stay empty because of condition, layout, location or rent level, and which will not fill without capital or price change.

Buyers usually apply a vacancy and collection allowance to the building’s potential rent, whether or not the building is currently full. A building that is 100% occupied today will still be underwritten with an allowance. See how to calculate NOI for how the allowance is applied.

How Vacancy Flows into Value

Value equals NOI divided by a capitalization rate, so any change in vacancy that changes NOI changes value by a multiple of itself. The figures below are an arithmetic illustration only and are not market data. Suppose a 40-suite building could collect $960,000 a year if fully occupied, and operating expenses are $360,000 whatever the occupancy.

Three extra points of vacancy cost $28,800 of income, which at a 5.0% cap rate is $576,000 of value. Expenses such as heat, property taxes and insurance do not fall when suites are empty, so vacancy falls almost entirely to the bottom line.

Ontario’s Rent Rules Change the Meaning of Vacancy

In Ontario, annual rent increases for most existing residential tenancies are limited by the provincial rent increase guideline. Some units are exempt, including new buildings and additions first occupied for residential purposes after November 15, 2018. When a tenancy ends and a new tenant moves in, the landlord and the new tenant agree the rent, which is why turnover matters so much to buyers. The gap between in-place rents and what a vacated suite can be re-rented for is sometimes called loss-to-lease. Two consequences follow:

• Vacancy can create value: a suite turned over and re-let at market rent may increase NOI, so turnover is not purely a cost.
• Low turnover can hide unrealized income: a building with very long-tenured tenants may show full occupancy but rents well below market, and buyers will price both sides of that.

Ending a tenancy is regulated under the Residential Tenancies Act, 2006 and disputes are handled by the Landlord and Tenant Board, so buyers will not assume they can empty suites quickly. Have your lawyer confirm how these rules apply to your building.

What Buyers Ask About Your Vacancy

• How many suites are vacant, and for how long has each been empty?
• Why are they vacant: condition, price, layout, renovation or an owner decision?
• What is the average time to re-let a suite, and what incentives were used?
• What did new tenants pay compared with the previous rent?
• How much capital does each vacant suite need to be market-ready?
• What are the arrears and bad-debt records over several years?

Answering these with records shows that vacancy is understood and managed. Vague answers lead buyers to assume the worst.

Using Market Vacancy Data Carefully

Benchmarks help buyers judge whether a building’s vacancy is normal for its area and type. CMHC publishes an annual Rental Market Report with vacancy rates and average rents for purpose-built rental apartments in major centres, and it is a widely used, authoritative source. Its figures describe broad markets and categories, not your building, so they are a starting point for comparison, not a substitute for your rent roll. Always check the date and geography of any figure you cite.

How Sellers Can Prepare

• Prepare a current rent roll showing each suite’s rent, lease start, tenancy status and any arrears.
• Document turnover for the past few years, including days vacant and rents achieved on re-letting.
• Explain any long-term vacant suites with a plan and a cost estimate.
• Complete inexpensive repairs that make suites easier to lease before marketing.
• Reconcile the rent roll with bank deposits and financial statements.
• Be prepared to show how rents compare with market, supported by real lease comparables.

The seller process is described in how to sell an apartment building in Ontario, and the valuation methods in how to value an apartment building.

Common Mistakes

• Presenting current occupancy as if it were permanent, with no allowance for turnover.
• Ignoring the cost and time of preparing vacant suites for lease.
• Failing to explain long-term vacancies.
• Confusing physical occupancy with collected income, which arrears and concessions can reduce.
• Assuming vacant suites can be re-let at rents unsupported by comparables.
• Overlooking rent-control status when comparing in-place rents with market rents.

Frequently Asked Questions

How do buyers treat vacancy in an apartment building?

They usually apply a vacancy and collection allowance to potential rent, plus adjust for any suites that are vacant for structural reasons.

Is a fully occupied building always more valuable?

Not necessarily. A full building with rents far below market and low turnover may have less near-term income growth than one with a manageable vacancy rate and market rents.

What is loss-to-lease?

The difference between the rents tenants currently pay and the rents a vacated suite could be re-let for at market levels.

Are all Ontario apartments subject to the rent increase guideline?

Not all. Some units, such as those in buildings first occupied for residential purposes after November 15, 2018, are exempt. Confirm which units in your building are covered.

Where can I find market vacancy data?

CMHC’s Rental Market Report is a common source. Check the date, geography and property category before relying on any figure.

Should I renovate vacant suites before selling?

Sometimes. Weigh the cost against the rent increase buyers will credit and the time to lease, and discuss it with your broker.

Conclusion

Vacancy affects apartment building value through lost income, turnover costs and the rent a suite can command when it turns over. Ontario’s rent rules add a further layer, because vacancy can be either a cost or an opportunity. Owners who document their occupancy history, explain any vacancies and support market rents with evidence give buyers the confidence to pay for the building’s income. If you are considering selling an apartment building in the GTA or Southern Ontario, a property-specific valuation and market strategy can help you understand your options before entering the market.
