In this situation the first thing you should try is to talk to your tenants about your plans for the house and ask them if they are willing to move out on their own. If they agree to move out you should have them sign an Agreement to End the Tenancy (Form N11). If they do not agree to move out, you will not be able to serve them with a notice of termination, however you can put the house up for sale. You can only give notice to the tenants once an Agreement of Purchase and Sale has been signed and the new owner requires the house for their own personal use. At that point you can serve the Form N12 on behalf of the purchaser.
As of July 21, 2020 the landlord is required to give the tenant one month’s rent as compensation, or offer the tenant another acceptable unit if pursuing the N12 notice on behalf of the purchaser. The compensation must be given before the termination date on the notice.
