Whether you are seeking to set up your business in an industrial area, shopping mall, retail strip or business center, you will need to sign a legal contract with a property owner, manager or leasing agent. While the terms �lease' and �rental agreement' are sometimes used interchangeably, more often a lease refers to an agreement that lasts a year or more, while a rental agreement involves a month-to-month committment. A rental agreement will establish the terms of use for the space, the amount to paid periodically for the use of the space, and the terms and amounts of other fees such as security deposits. The agreement will include legal ramifications and remedies should any of portion of the agreement be broken.
