Writing a rental contract, when a housing unit shall be rented or leased is not a necessity, if not of the tenant or the landlord requires it. However, we do recommend is to document the terms of the agreement in a written contract, so it's easier to see what are your rights and responsibilities.

This could include:
What is the rent to be paid, and when?
If the rent is not paid, the how to become a landlord by his tenants, and how the client may still have the opportunity to live in their home?
To get a tenant to do about the apartment, such as wall paper?
Who is responsible for the damage caused to the property?
