GTA real estate made a lot of investors wealthy between 2010 and 2022, mostly because prices kept rising and borrowing was cheap. In 2026 the math is different. Prices are below their 2022 peak, rates are higher than they were then, and rental rules in Ontario favour tenants. Investing can still work, but these mistakes sink more first-time investors than anything else.
1. Counting on appreciation to cover negative cash flow
Many condos bought in 2021 and 2022 rent for less than the mortgage, fees and taxes. Run the numbers at today’s rate before you buy: rent minus mortgage, property tax, condo fee, insurance, a vacancy allowance and a repair reserve. If the result is negative, you are betting on price growth. See how prices have moved in our GTA home price history.
2. Not understanding rent control
In Ontario, most units first occupied before November 15, 2018 are rent controlled. The 2026 guideline limits increases for sitting tenants to 2.1 per cent a year. Units first occupied after that date are exempt from the guideline, which is why newer condos and many new basement units can reset rent more freely. Know which rules apply before you project income.
3. Underestimating how long it takes to resolve a tenant problem
The Landlord and Tenant Board handles non-payment and eviction applications, and hearings can take months. Screen carefully, get references and credit checks, and keep a cash reserve that covers several months of carrying costs.
4. Buying for short-term rental income
Toronto only allows short-term rentals in your principal residence, and entire-home rentals are capped at 180 nights a year. Many condo buildings ban them outright. An investment property in Toronto cannot legally run as a full-time Airbnb. Read our summary of Toronto’s short-term rental rules.
5. Ignoring taxes
- Rental income is taxable, and when you sell, the gain is a capital gain rather than tax-free like a principal residence.
- Selling within 12 months can trigger the federal anti-flipping rule, which taxes the whole gain as business income.
- Non-residents and some temporary residents face Ontario’s 25 per cent non-resident speculation tax and the federal foreign buyer ban.
Talk to an accountant before you buy, not after.
6. Picking the wrong property type
In 2026, the GTA investments that tend to cash flow best are not small downtown condos. They are often freehold homes with a legal second unit in Brampton, Mississauga or Scarborough, where two rents share one mortgage. Make sure the second unit is registered with the City and meets fire code.
A simple test before you buy
- Can you carry the property for a year with no tenant?
- Does it cash flow at today’s rate, not a hoped-for lower one?
- Would you still buy it if prices stayed flat for five years?
If the answers are yes, you are investing. If not, you are speculating. More in our guide to the pros and cons of owning a rental property.
