Use a commercial lease if you are renting an office building, retail space, restaurant, industrial establishment or property in which the tenant operates a business. Whether you choose a lease or a lease, it is essential that you know who your tenant is. A thorough review of your tenants can give you the confidence that you are putting the right person in your apartment to rent. If he does not practice the expressly resolved option set out by law or contract, the contract remains in force and the civil judge is legally entitled to assess the actual use of the property as well as the conscience and implicit tolerance expressed by the owner (in the absence of resolute action with regard to the contract). Suddenly, the judge is entitled to determine the new contractual agreement, so that its clauses are consistent with the actual purpose of the use of the building. The importation of the contractual obligation (annual rent) is generally recalculated under standard contracts defined by the association of owners and owners of real estate, both nationally and provincially.  You rent a room in your home using a rental agreement stating that you rent only one room and not the entire property. If you live in a rented apartment, you can sublet a room to another tenant through a room rental agreement. A tenancy agreement is a lease agreement, usually in writing, between the owner of a property and a tenant who wishes to temporarily hold the property; it is different from a lease that applies rather for a fixed term.  The agreement refers to the parties, the property, the duration of the tenancy and the amount of the rent for the minimum term. The owner of the property may be designated as the owner and the tenant as the tenant. Examples of arrangements that should also be made for the simplest lease are: If you decide whether a lease or rent is best for you, remember that a lease offers more security, but a lease offers more flexibility.
