What it costs to buy 1808 Castlemore Avenue
At the asking price of $1,088,800, a buyer in Markham pays Ontario land transfer tax on closing. The City of Toronto is the Ontario municipality that charges a municipal land transfer tax of its own, so there is no second tax here.
| Asking price | $1,088,800 |
|---|---|
| Ontario land transfer tax | $18,251 |
| First-time buyer refund, if you qualify | up to $4,000 |
| Minimum down payment | $83,880 |
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. The tax is worked out at the published rates for a home with one or two single family residences and your lawyer confirms the final amount. Legal fees, title insurance and adjustments are extra: our closing costs guide lists them. 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) | $5,453 a year, about $454 a month |

That is before a mortgage payment, home insurance and utilities. These are the figures on the listing, so check the current tax bill before you rely on them.
How the asking price compares

What to check before you make an offer
- Book a home inspection. An inspection looks at the parts of a house you cannot judge at a showing. Our guide explains what a home inspection covers and misses.
- Ask for the survey. The listing gives the lot as 36.02 by 98.68 feet. If the seller has a survey, check the lot lines, fences and any easements against it.
- Confirm what stays. Have the appliances, fixtures and any rented equipment written into the offer.
- Confirm the parking. The listing shows 3 parking spaces.
- Get your financing in writing. A lender looks at the property tax as well as the price.
- See it in person. photos do not show noise, light at different hours or the condition of the roof, the basement and the yard.

Questions about Greensborough
Is Greensborough walkable to the GO station?
For a meaningful share of the neighbourhood, yes. Mount Joy sits inside the community rather than at its edge, which is unusual for north Markham and it is the main reason people buy here.
Is there a lot of townhome supply?
Yes. From January to March 2026 the all property types median here was $980,100, below Wismer at $1,048,000 and Berczy at $1,232,000 (TRREB). The supply also means more competition when you sell. Condition and presentation decide outcomes here.
Does it suit investors?
The townhome and condo stock plus the GO station make it one of the more rentable pockets in Markham. Run your own numbers and confirm current rules before you buy for that purpose.
How does it compare to Wismer?
Similar age and style. Greensborough has more attached and stacked stock and better station access. Wismer skews slightly more detached.
What is the shopping like?
Plazas along Markham Road and Bur Oak Avenue cover day to day needs. There is no main street.
How old are the houses?
Mostly mid 2000s onward, so mechanicals are newer and major repairs are usually still some years away.
