5 Mistakes First-Time Rental Property Owners Make in Ontario

By D&D Property Management Team January 15, 2026 3 min read Blog

The first rental property purchase comes with a learning curve — these are the most common and most expensive mistakes first-time landlords make in the Ontario market.

Lease and Rental Management

The first rental property purchase comes with a learning curve — these are the most common and most expensive mistakes first-time landlords make in the Ontario market.

Underestimating carrying costs is the most common financial mistake. Many first-time landlords budget for mortgage, tax, and insurance but forget: property management fees (if using a manager), maintenance reserve (1–2% of property value annually), vacancy allowance (2–4% of annual rent), and capital expenditure reserve. These items can turn a projected positive cash flow into a break-even or negative cash flow situation.

Ontario Tenancy Law

Skipping professional tenant screening is the mistake that creates the most ongoing pain. The time savings of accepting the first interested applicant without running credit, employment verification, and reference checks is consumed many times over when a problematic tenant creates arrears, property damage, or LTB proceedings.

Not understanding the Residential Tenancies Act before starting. Ontario's RTA is tenant-protective and complex. New landlords who don't know the notice requirements, maintenance obligations, and entry rules regularly make procedural errors that void their legal proceedings or result in LTB orders against them.

Protecting Landlord Rights

Failing to conduct and document a move-in inspection. Without a signed move-in inspection with photographs, you have no baseline for damage claims when the tenant leaves. Ontario's first-and-last month deposit system means you have no financial buffer beyond the last month's rent — and that can only be applied to rent, not damage.

Pricing rent based on carrying costs rather than market rate. The market doesn't care what your mortgage payment is. If comparable units are renting for $1,800 and your carrying costs require $2,200, the market will leave your unit vacant. Price to market, ensure the numbers work at market rate before purchasing, and don't price yourself out of tenants.
