Most guides to property management assume you're running a portfolio. They talk about scaling, systems, and efficiency across dozens of doors.
But a large share of Ontario landlords own exactly one rental property — a basement unit added to a family home, a house you moved out of but didn't sell, a condo bought as an investment, or a property inherited from a parent. One tenant. One unit. And all the same legal obligations as a landlord with twenty.
This post is for you.
Why One Property Is Still a Full-Time Responsibility
Owning a single rental property doesn't reduce your exposure under the Residential Tenancies Act. Every obligation that applies to a large apartment building applies to your one-unit rental:
- Maintaining the unit in a good state of repair
- Following proper notice procedures for entry, rent increases, and lease renewals
- Filing the correct Landlord and Tenant Board forms if problems arise
- Tracking last month's rent deposits and paying interest annually
- Providing the mandatory Ontario Standard Lease to every new tenant
When you have a portfolio, a single mistake costs you a fraction of your income. When you have one property, a bad tenant, an LTB application, or a six-month vacancy doesn't dilute across other units — it hits your full investment.
The Four Breaking Points for Single-Property Landlords
Most one-property landlords manage fine until they hit one of these four situations. Any of them can turn a passive investment into a part-time job.
1. A problem tenant
You placed a tenant who looked fine on paper. They pay late, disturb neighbours, or stop paying entirely. Now you're navigating N4 notices, LTB wait times, and a process you've never been through before — with no experience and no time to learn it quickly.
Ontario's eviction process has specific forms, specific timelines, and specific rules for serving documents. Getting any step wrong resets the clock. For a landlord with one property and no prior LTB experience, this is where the stress becomes acute.
2. A vacancy you can't fill
The unit sits empty for two months while you try to find a tenant. You're running ads, fielding calls at inconvenient hours, doing showings on evenings and weekends, and screening applications without a reliable process. On a $1,900/month London rental, two months vacant costs $3,800 — more than a full year of management fees.
3. A maintenance problem you don't know how to handle
The furnace breaks in January. There's water coming through the basement wall. The tenant is asking for repairs you're not sure are your responsibility. Single-property landlords often lack contractor relationships, don't know what things should cost, and aren't always clear on what the RTA requires them to fix vs. what falls on the tenant.
See landlord maintenance responsibilities in Ontario for a full breakdown of what the law requires.
4. A life change that removes your bandwidth
You take a demanding new job. You move to a different city. You have a new child. You travel frequently. Whatever the reason, the time and attention the property used to get is no longer available — but the property doesn't care. Rent still needs to be collected, issues still need to be addressed, and your RTA obligations don't pause.
What a Property Manager Does for a One-Property Landlord
A professional property manager handles all of this:
Tenant placement
- Professional photography and listing across major platforms
- Pre-screening calls to filter unqualified applicants
- Credit checks, employment verification, reference checks, and rental history review
- Lease preparation using the Ontario Standard Lease with appropriate addenda
Day-to-day management
- Rent collection and automated reminders
- Maintenance coordination with vetted contractors
- Tenant communication — including complaints, requests, and disputes
- Move-in and move-out inspections with documentation
Legal compliance
- Rent increases served on the correct form with proper notice
- LTB applications filed when needed (N4, N5, L1, L2)
- LTB hearing attendance and representation
- Last month's rent interest tracking and disclosure
Vacancy management
- Market rent analysis to price the unit correctly
- Rapid re-leasing when a tenancy ends
- Unit turnover coordination between tenants
For a one-property landlord, a PM removes the operational layer entirely. You receive a monthly statement and a deposit. Everything else is handled.
What It Costs — and Whether It's Worth It
Property management for a single Ontario rental typically runs:
- Monthly management fee: 8–12% of gross rent collected
- Leasing fee: Roughly one month's rent when a new tenant is placed
- Renewal fee: Some companies charge a half-month's rent; others include it in the monthly fee
On a $1,900/month London rental at 10%, your monthly management fee is $190. At 8%, it's $152. The leasing fee of ~$1,900 is charged once per tenancy, not annually — so if your tenant stays two years, that's roughly $950/year amortized.
Year-one total (management fee + leasing fee): approximately $4,180 on a $1,900/month unit.

That sounds like a lot until you compare it to:
- One month of vacancy: $1,900
- Two months of vacancy: $3,800
- One LTB application filed incorrectly and refiled: 4–6 months of lost time
- One repair overcharged because you had no contractor relationships: varies, but often $300–$800+
For most one-property landlords in London, St. Thomas, or Strathroy, a well-run PM pays for itself if it prevents one bad tenant placement or one vacancy month per year.

When Self-Managing Still Makes Sense
Professional management isn't right for everyone. You might be fine managing yourself if:
- You live close to the property and are genuinely available
- You've been through the LTB process before and know the forms
- Your current tenant is long-term, pays reliably, and rarely has maintenance requests
- You have contractor relationships and understand what repairs should cost
- You have time and want to keep the management experience close
The tipping point is usually one of the four breaking points above. Many landlords self-manage successfully for years, then hit a problem tenant or a vacancy and decide they don't want to navigate the next one alone.
If you're unsure, when to hire a property manager in Ontario walks through 10 concrete triggers that usually mark the right time.
What to Look for in a PM as a Single-Property Owner
Not every property management company is set up to serve landlords with one unit. Some firms focus on portfolios of 10+ doors and treat one-property owners as low priority. Others are well-suited to smaller clients.
When you're evaluating companies, ask:
Do you manage single-unit properties? Some firms require a minimum of three or five units. Know this before you invest time in a conversation.
What does your screening process look like? Get specifics. A strong answer includes credit checks through Equifax or TransUnion, employment verification via pay stubs or an employer call, reference calls to previous landlords (not just contact information), and a rental history review. Vague answers about "our experience" without process detail are a red flag. For what to watch for in applicants, see tenant screening red flags Ontario landlords miss.
How are maintenance requests handled? Who do tenants contact? How fast does maintenance get dispatched? Do you mark up contractor invoices, and if so, by how much? A company that can't answer the markup question clearly is likely hiding a significant cost.
What happens if the tenant doesn't pay? This is where RTA knowledge matters. The PM should walk you through their process: N4 served on day 15, L1 filed after the N4 termination date passes, LTB hearing attendance, sheriff enforcement if needed. If the answer is vague or skips steps, their legal knowledge isn't deep enough to protect you.
What is included in the monthly fee? Know exactly what's covered and what triggers additional charges. Common add-ons: lease renewals, LTB appearance fees, maintenance supervision fees above a threshold. Get the fee schedule in writing before signing.
What is the management agreement termination clause? You should be able to exit the agreement with 60–90 days' notice if the relationship isn't working. Avoid firms that lock you in for a fixed term with no exit.

A Note on Ontario's LTB Timelines
If you're evaluating whether a PM is worth the cost, factor in the current state of the Landlord and Tenant Board. Hearing wait times in Southwestern Ontario have ranged from three to nine months depending on application type and scheduling priority.
A PM who has filed dozens of L1 applications, knows how to build a strong application package, and attends hearings regularly will move through the process more efficiently than a landlord doing it for the first time. That experience gap has direct financial value when something goes wrong.
The Bottom Line
Owning one rental property in Ontario is not a passive investment by default. It has the same legal obligations, the same potential for tenant disputes, and the same exposure to vacancy as any other rental. What it lacks is the scale that makes professional support feel obvious.
For most one-property landlords — especially those who work demanding jobs, live at a distance, or have had one difficult experience — a well-run property manager removes the operational burden at a cost that pays for itself in prevented problems.
If your property is in London, St. Thomas, Strathroy, or the surrounding area, Prospera Properties works specifically with small residential landlords. We handle tenant placement, maintenance coordination, rent collection, and RTA compliance — so you don't have to become an expert in Ontario landlord law to protect your investment.
