The Hidden Cost of Setting Rent Too Low

Every landlord wants a rental property that stays occupied.

After all, an empty property means no rental income.

So when a landlord finds a tenant quickly, it can feel like a win.

The property is occupied. Rent is coming in. There’s no vacancy to worry about.

But there’s another problem that doesn’t get talked about as much:

What if you’re charging too little?

Maybe your property is renting for $1,800 when comparable properties could reasonably achieve $2,000.

At first, $200 might not seem like a huge difference.

But that’s $2,400 every year.

Over five years, that’s $12,000 in gross rental income.

And unlike a major repair bill, this loss can be almost invisible. You’re not receiving a bill that says you’re losing $200 every month.

You simply never collect it.

That’s the hidden cost of setting rent too low.

Why Do Landlords Underprice Their Rentals?

There are plenty of understandable reasons.

Some landlords intentionally price below the competition because they want to attract tenants quickly.

Others may:

• Want to avoid vacancy.
• Be nervous about asking for more.
• Haven’t reviewed local rental prices recently.
• Base their price on an old rental estimate.
• Want to attract as many applications as possible.
• Prefer keeping a long-term tenant happy.
• Worry that increasing rent will cause a tenant to leave.
• Simply not have the time to monitor the market.

And sometimes, setting a slightly lower rent can be a smart strategy.

A property that rents quickly at a competitive price can outperform a property that sits vacant for weeks waiting for a higher-paying tenant.

The problem isn’t necessarily charging slightly below the maximum possible rent.

The problem is underpricing without knowing you’re doing it.

The $100 Mistake That Can Cost You Thousands

Let’s make this simple.

Imagine your rental is consistently underpriced by:

Monthly Difference	Annual Difference
$50	$600
$100	$1,200
$150	$1,800
$200	$2,400
$300	$3,600

Now imagine that difference continues for five years.

A $100 monthly gap becomes:

$6,000

A $200 monthly gap becomes:

$12,000

A $300 monthly gap becomes:

$18,000

That’s a significant amount of money for an investment property.

And remember: this isn’t necessarily money you’re losing because of a bad tenant or unexpected repair.

It’s money you’re potentially leaving on the table because the rental was priced incorrectly.

“But Isn’t Lower Rent Better for Landlords?”

Not necessarily.

Lower rent can absolutely help attract attention.

But more applications don’t automatically mean more profit.

Consider two hypothetical rentals.

Property A

Monthly rent: $1,800

It rents immediately.

Property B

Monthly rent: $2,000

It takes a little longer to find the right tenant.

At first glance, Property A might seem like the obvious winner because there was almost no vacancy.

But the landlord needs to look at the entire leasing cycle.

If the $2,000 property rents quickly enough to justify the difference, the additional income could outweigh a short vacancy period.

On the other hand, if asking $2,000 results in months of vacancy, the lower price may be the better financial decision.

That’s why rental pricing isn’t about simply asking:

“What’s the highest rent I can charge?”

It’s about asking:

“What’s the most sustainable rent the market will support while keeping vacancy under control?”

The Hidden Cost of Long-Term Underpricing

The obvious cost of underpricing is lost monthly income.

But there are other consequences worth considering.

1. Lower Monthly Cash Flow

If your property could reasonably generate another $200 per month, you’re leaving $2,400 of potential gross rental income on the table each year.

2. Lower Annual Income

That monthly difference becomes meaningful when you look at your entire year.

A $200 monthly difference isn’t really $200.

It’s $2,400 per year.

3. Reduced Investment Performance

Rental income is an important part of a property’s financial performance.

If you’re consistently collecting less than the market reasonably supports, your property’s income potential is lower than it could be.

4. Less Money Available for the Property

Additional rental income could potentially help cover:

• Maintenance
• Repairs
• Insurance
• Property taxes
• Mortgage costs
• Capital improvements
• Future investment opportunities

5. Difficulty Correcting the Gap Later

This is particularly important in Ontario.

Landlords need to understand the difference between setting the rent for a new tenancy and increasing rent for an existing tenant.

For most rent-controlled units, rent increases are subject to Ontario’s rules, including the annual guideline, timing requirements and notice requirements. For 2026, the Ontario rent increase guideline is 2.1% for most rent-controlled units.

That means an owner shouldn’t assume they can simply underprice a unit today and immediately bring it up to whatever the current market rent is later.

Getting the pricing strategy right matters.

Ontario’s Rent Rules Make Pricing Even More Important

This is where landlords need to be careful.

For most Ontario tenants covered by the Residential Tenancies Act, a landlord generally can’t increase the rent whenever they want.

Ontario’s 2026 guideline is 2.1%, and most rent-controlled tenants are subject to that guideline unless an applicable exception or Landlord and Tenant Board-approved increase applies.

Generally, landlords must also wait at least 12 months between rent increases and provide the required written notice.

However, there are important exemptions.

For example, the rent increase guideline generally does not apply to certain newer rental units that were first occupied for residential purposes after November 15, 2018, subject to the applicable rules. Ontario’s official guidance should always be checked for the specific property and tenancy.

This is why landlords shouldn’t rely on a simple rule like:

“I’ll just increase it later.”

Your property’s circumstances matter.

Hamilton and Niagara Rental Markets Are Changing

Rental pricing decisions should also reflect what’s happening in the local market.

CMHC’s rental-market data shows that the Hamilton and St. Catharines–Niagara markets have experienced meaningful changes in vacancy, rents and rental supply.

CMHC’s 2025 Rental Market Report recorded a 3.9% vacancy rate in St. Catharines–Niagara, with an average two-bedroom purpose-built rent of $1,527, up 5.5% year over year.

More broadly, CMHC’s 2026 outlook says Canadian rental markets are continuing to ease, with higher vacancy rates and slower rent growth expected as rental supply increases and demand becomes more balanced.

That doesn’t mean every Hamilton or Niagara landlord should raise—or lower—their rent.

It means landlords need to pay attention to the market they’re actually operating in.

A property in downtown Hamilton isn’t necessarily competing with a property in Stoney Creek.

A rental in St. Catharines isn’t necessarily competing with a rental in Niagara Falls.

And a renovated three-bedroom house shouldn’t be priced solely by looking at the average rent for all three-bedroom units in the region.

Local and property-specific comparisons matter.

Don’t Confuse “Market Rent” With the Highest Rent You See Online

Here’s another common mistake.

A landlord finds a similar property online listed for $2,500 and thinks:

“Mine should rent for $2,500.”

Not so fast.

An advertised rent tells you what someone is asking.

It doesn’t necessarily tell you what a tenant actually agreed to pay.

When evaluating your rental, look at as much relevant information as possible:

• Similar properties currently available.
• Comparable properties that have recently rented.
• Location.
• Property condition.
• Number of bedrooms and bathrooms.
• Parking.
• Laundry.
• Utilities.
• Outdoor space.
• Appliances.
• Renovations.
• Building type.
• Pet policies.
• Overall tenant demand.

CMHC’s Rental Market Survey provides useful market-level information on vacancy rates, average rents and other rental indicators across Canada and major centres.

But market-level data should be treated as a starting point—not a replacement for property-specific analysis.

What Happens When You Underprice by $200?

Let’s say you’ve determined that your property could reasonably achieve approximately $2,200 per month in the current market.

Instead, you decide to list it at $2,000 because you want to attract tenants quickly.

The difference is:

$200 per month.

That doesn’t sound huge.

Until you do the math.

One year:

$200 × 12 = $2,400

Three years:

$200 × 36 = $7,200

Five years:

$200 × 60 = $12,000

That’s potentially $12,000 in gross rental income that was never collected.

Of course, this example doesn’t mean that $2,200 would necessarily have been achieved or that a $2,000 price was wrong.

There could be vacancy costs, market conditions, property differences and other factors.

The point is simply this:

Small pricing decisions become much bigger when multiplied by time.

But Don’t Overprice Just to Avoid Underpricing

There’s an important balance here.

The solution isn’t to look at your competitors and simply choose the highest number.

Overpricing can create its own problems.

A rental that is priced too high may experience:

• Fewer inquiries.
• Fewer showings.
• Longer vacancy.
• Repeated price reductions.
• Additional marketing costs.
• Frustrated prospective tenants.
• Lost rental income.

That’s why the goal isn’t:

“Get the highest rent possible.”

The goal is:

“Get the highest sustainable rent the market will support.”

Those are two very different things.

How Do You Know If You’re Underpricing Your Rental?

There isn’t one magic number that proves a property is underpriced.

Instead, look for indicators.

Ask Yourself: When Was the Last Time You Reviewed the Rent?

If you haven’t looked at comparable properties in a long time, your market may have changed.

Rental markets aren’t static.

Demand, supply, neighbourhood development, employment, construction and tenant preferences can all influence what renters are willing to pay.

Are You Getting an Unusually High Level of Qualified Interest?

If a property receives a large amount of qualified interest almost immediately, it’s worth reviewing whether the pricing is competitive.

But be careful.

Strong demand alone doesn’t prove that your rent is too low.

A particularly desirable property can generate strong interest even when correctly priced.

Are Comparable Properties Renting for More?

This is one of the strongest indicators.

If several genuinely comparable properties are consistently achieving higher rents, investigate why.

The difference could be justified by:

• Better renovations.
• Better location.
• Parking.
• Laundry.
• Larger floor plan.
• Better amenities.

But if the properties are genuinely comparable, the difference deserves attention.

Is Your Long-Term Tenant Significantly Below Market?

This is a particularly sensitive situation.

A long-term tenant can be extremely valuable.

Tenant turnover costs money.

A reliable tenant who pays rent on time and takes care of the property has value beyond the monthly rent.

So don’t automatically assume that maximizing rent today is the best decision.

At the same time, landlords should understand their property’s financial position and the applicable Ontario rent rules.

Good property management is about balancing income and retention—not chasing one at the expense of the other.

Tenant Retention Has Value Too

This is an important part of the conversation.

A landlord might discover that their tenant is paying $150 below what a new tenant might pay.

Does that automatically mean the landlord should push for the maximum possible increase?

Not necessarily.

Replacing a good tenant can involve:

• Cleaning.
• Repairs.
• Painting.
• Advertising.
• Showings.
• Screening.
• Administrative work.
• Vacancy.
• Turnover costs.

A good tenant also reduces risk.

So rental pricing should always be considered alongside tenant quality and retention.

The best investment decision isn’t always the one that produces the highest monthly rent on paper.

Sometimes keeping an excellent tenant at a reasonable rent can be the better long-term strategy.

Rental Pricing Is an Investment Decision

Many landlords think of rent as simply a number they put on a listing.

But rental pricing affects the entire investment.

It can influence:

• Monthly cash flow.
• Annual income.
• Vacancy.
• Tenant demand.
• Turnover.
• Property expenses.
• Overall investment performance.

That’s why pricing deserves more attention than simply looking at one comparable listing online.

Your rental property is an investment.

The rent should be managed like an investment number.

A Simple Rental Pricing Strategy for Ontario Landlords

If you’re trying to determine whether you’re charging too little, start with these steps.

Step 1: Know Your Property

Understand what makes your rental different.

Consider:

• Location.
• Size.
• Condition.
• Parking.
• Laundry.
• Utilities.
• Outdoor space.
• Renovations.
• Appliances.

Step 2: Research Comparable Rentals

Look for properties that genuinely compete with yours.

Don’t compare a renovated detached home with an older apartment simply because they have the same number of bedrooms.

Step 3: Review Current Market Conditions

Look at current local data and rental-market reports.

CMHC’s Rental Market Survey is a useful starting point for understanding broader market conditions.

Step 4: Consider Vacancy

Ask yourself:

Would charging another $100 per month be worth the possibility of an additional month of vacancy?

Run the numbers.

Step 5: Consider the Tenant

A qualified, reliable tenant has value.

Don’t sacrifice tenant quality simply to chase an extra few dollars.

Step 6: Check Ontario’s Rules

If you’re dealing with an existing tenant, make sure you understand the applicable rent-increase rules before making a change.

Step 7: Review Regularly

Don’t wait several years before looking at the market again.

Rental pricing should be an ongoing part of managing an investment property.

How Professional Property Management Can Help

This is where having a professional property management team can make a significant difference.

A property manager can help landlords evaluate the full picture instead of simply choosing a number that “feels right.”

That can include:

• Reviewing local rental competition.
• Monitoring market conditions.
• Recommending competitive pricing.
• Marketing the property effectively.
• Responding to prospective tenants.
• Coordinating showings.
• Screening applicants.
• Managing lease renewals.
• Tracking vacancy.
• Monitoring tenant retention.
• Staying informed about applicable Ontario tenancy rules.

At Welcome Home Management, the goal isn’t simply to get the highest rent possible.

It’s to help owners make smart, sustainable rental decisions based on the property, the local market and the owner’s long-term goals.

Because maximizing rent isn’t useful if it creates unnecessary vacancy.

And filling a property quickly isn’t necessarily a win if you’re consistently leaving thousands of dollars on the table.

The Bottom Line: Don’t Leave Money on the Table

Setting rent too low can feel like the safe choice.

The property rents quickly.

You get lots of interest.

You avoid vacancy.

You have a tenant.

Everything looks good.

But if you’re consistently charging significantly below what your property could reasonably achieve, the lost income can quietly add up.

A $100 difference can become $1,200 a year.

A $200 difference can become $2,400.

A $300 difference can become $3,600.

Over several years, that’s real money.

At the same time, landlords shouldn’t make the opposite mistake and simply chase the highest rent they can imagine.

The goal is not the highest rent.

The goal is the right rent.

A price that is competitive enough to attract qualified tenants, high enough to support your investment, and realistic enough to avoid unnecessary vacancy.

For landlords in Hamilton and Niagara, that means keeping an eye on the local market rather than relying on outdated assumptions.

Because sometimes the biggest cost in your rental property isn’t a broken furnace, a vacant month or an unexpected repair.

Sometimes it’s the money you never realized you were leaving on the table.
