Tax Classification for Multi-Member LLC for Co-Ownership of Property

My two siblings and I inherited a small commercial property from our mother.  The property has a triple net lease, so it requires no active management.  I have set up an LLC to hold the property.  Now I am completing the online request for an EIN, and the tax organization selection section says the following:

"An unincorporated organization with two or more members is generally classified as a partnership for federal tax purposes if its members carry on a trade, business, financial operation, or venture and divide its profits. However, a joint undertaking merely to share expenses is not a partnership. For example, co-ownership of property maintained and rented or leased is not a partnership unless the co-owners provide services to the tenants."

So it says that it is not a partnership, but I can't find any further information on the correct classification for this scenario.  Can anyone point me to instructions regarding the correct tax classification for a multi-member LLC whose only activity is ownership of a commercial property with lease income and no services provided to the tenant?  Thank you!
