Often, terms are negotiated between the two parties to establish that in the management of an interested tenant, it is better to understand his needs and agree. Therefore, it may be a good idea for you and your agent (if any) to get creative with the tenant to make a deal that works for both parties. After the release of the surety and the signing of the lease, the tenant must begin the occupation. This means that the tenant can start using the space as stated in the rental agreement. Both parties are required to report on their defined obligations until the end of the rental period. Companies also use leases to rent buildings for themselves. This type of contract is called a commercial lease agreement.
