What it costs to buy 12 Sarnia Avenue
At the asking price of $1,230,000, a buyer pays two land transfer taxes on closing: the Ontario tax and the City of Toronto's municipal tax. Both apply to every home inside the City.
| Asking price | $1,230,000 |
|---|---|
| Ontario land transfer tax | $21,075 |
| Toronto municipal land transfer tax | $21,075 |
| Both taxes | $42,150 |
| First-time buyer relief, if you qualify | up to $8,475 |
| Minimum down payment | $98,000 |
The down payment figure is the federal minimum: 5 percent of the first $500,000 and 10 percent of the rest. A lender can ask for more. These figures use the asking price, so they change if you pay more or less. Legal fees, title insurance and adjustments are extra: ask your lawyer for a written quote. This is general information, not legal or tax advice. Confirm the figures with a lawyer or accountant. You can change the price in our land transfer tax calculator and our mortgage calculator.
What it costs to own each month
| Property tax (2026) | $5,609 a year, about $467 a month |

That is before a mortgage payment, home insurance and utilities. The listing shows no monthly maintenance fee, so upkeep of the building and the lot is the owner's own cost.
What to check before you make an offer
- Book a home inspection. An inspector looks at the roof, foundation, wiring, plumbing and heating. The listing gives the heating as forced air.
- Have a lawyer search the title. A title search shows mortgages, liens and easements registered against the property. Ask whether a survey exists and whether it matches the lot on the listing, 16 by 90 feet.
- Ask about permits. Ask which renovations had building permits and whether those permits were closed. The listing shows 2 kitchens. If there is a second unit, ask whether it meets the municipality's rules for one.
- Confirm what is included. Appliances, light fixtures and window coverings are included only if the agreement says so. Ask whether the water heater or furnace is rented.
- Get your financing in writing. A lender looks at the property tax and heating costs as well as the price.
- See it in person. Photos do not show noise, light at different hours or the state of the street and the homes beside it.
Our first-time home buyer guide and our page for buyers walk through each step. This is general information, not legal advice. Confirm the details with a lawyer.
