Rental contract forms may be purchased at certain office supply stores, stationary stores, or other locations that provide legal documents. Rental contract forms may also be available to download from various websites, either for free or for a small fee. Blank or sample forms may be used by landlords to create specific leases. A landlord may choose to alter a rental contract by adding clauses or deleting inapplicable provisions, or a rental form may be used as-is, as long as it complies with local and state laws. Laws governing the rental process can vary by state and even by city, therefore a landlord should check to make sure a rental contract is valid before attempting to use it. Many leasing companies make their rental contract forms available to view on their websites, giving potential tenants a chance to review the terms of a rental contract before deciding to rent a property.
