In addition, a rental agreement can be temporary or from one month to the next. Otherwise known as “landlord” and “tenant”, you decide who is called in the rental agreement. This is an important question that is asked of tenants who are going to live together, such as those who have a romantic relationship. A general rule is that if the rent can only be borne by the income of both people, then it is recommended that both people be listed as tenants. Once the lease is concluded and signed, give the tenant the keys so that he can move into the property. Since each rental property is different and laws vary from state to state, your lease may require additional disclosures and additions. These documents, which are attached separately to your rental agreement, inform new or existing tenants of problems with your property and its rights.
