Which one of the following is NOT a duty that a typical property manager does?

A typical property manager is responsible for a range of duties that primarily focus on the efficient day-to-day operation of rental properties. Among these responsibilities are making minor repairs, marketing the properties to attract tenants, and collecting rents. These tasks are essential for maintaining the property's value and ensuring a steady income stream.

Investing profits earned from clients' properties, however, falls outside the usual scope of property management. While property managers do manage properties and ensure they are profitable, the actual investment of profits into other ventures or financial instruments usually involves financial advisors or investment managers, rather than property managers. Their role is primarily centered around the operational management of real estate, not the strategic investment of funds generated from those operations. Therefore, investing profits is not a duty that is typically associated with the role of a property manager.
