Homes for sale by owner in Markham
Owner-listed Markham homes are on realtor.ca like any MLS® listing, and on private-sale and classified sites. The homes on this page are listed by their owners through us. Markham is in the Toronto Regional Real Estate Board's market (York Region), so agents across the GTA find them on the MLS® System.
Buyers contact the owner directly to view or make an offer, with a real estate lawyer reviewing the agreement. As a seller, your costs are the listing fee, your lawyer and the buyer agent commission you choose to offer; real estate commission in Ontario shows what keeping the listing side is worth at Markham prices. Markham has no land transfer tax of its own; buyers pay Ontario's only.

Selling a Markham home with a second suite
Markham now allows up to three units on every urban residential lot, so a basement apartment or second suite can add real value. The catch: "All two-unit houses must be registered with the City", and both units are inspected for building and fire safety before they're registered (markham.ca). Markham Fire charges $260 for the first inspection and $246 to register.
If your suite is registered, say so in your listing and keep the paperwork ready for buyers' lawyers. If it isn't, describe it plainly as a finished basement; a buyer planning to rent it out will check, and an accurate listing avoids a renegotiation after the offer.
Renting out your Markham home by owner
Markham is one of the tightest rental markets around Toronto. In CMHC's October 2025 survey of purpose-built apartments in the Markham zone, two-bedroom vacancy fell to 0.3%, from 1.8% a year before, with an average two-bedroom rent of $1,996 (CMHC data tables). Tenants are looking, many with an agent on the MLS® System. See list a rental on MLS®.
If the rental is a basement or second unit, register it first (above): a registered unit is easier to rent, easier to insure, and something a tenant's agent can confirm. Use Ontario's standard lease form and screen tenants the same way for every applicant.
Selling by owner in Markham: questions
Can I sell my Markham house without a realtor?
Yes. Ontario doesn't require a listing agent. A flat fee listing puts your Markham home on the MLS® System and realtor.ca; you show it and negotiate, and a real estate lawyer handles the closing.
Does a Markham basement apartment need to be registered?
Yes. All two-unit houses in Markham must be registered with the city after building and fire inspections. Markham Fire charges $260 for the first inspection and $246 to register.
How many units can I have on a Markham lot?
Up to three on any urban residential lot, under Markham's current rules. Each additional unit has to meet the building and fire codes and be registered with the city.
Is there a land transfer tax in Markham?
Only Ontario's. Markham doesn't charge a municipal land transfer tax, and the tax is the buyer's cost anyway.
Is it easy to rent out a home in Markham?
Markham is one of the tightest rental markets around Toronto. CMHC's October 2025 survey put two-bedroom vacancy in Markham's purpose-built apartments at 0.3%, down from 1.8% a year before, with an average two-bedroom rent of $1,996. Register any basement or second unit before you rent it.
