The choice of a manager naturally requires careful thought on the part of an owner. His desire will be to secure the services of an agent who will produce the best results with the property. The results of the agent's work will be shown not only in realizing the largest amount of net income obtainable, but also in the maintenance of the property in a normal and reasonable state of repair. The agent selected by the owner should be one possessing an accurate knowledge of conditions affecting rents so that when space in the building is to be rented a lease may be made for the owner on the best possible terms. If the owner or his agent does not know the market, valuable opportunities may be wasted. The knowledge the agent should possess comes only through experience and by his being in close touch with the requirements of tenants and the prices they are willing to pay for space. The agent should be one having trained assistants or associates to take care of each department of his business, i.e., collections, repairs, supplies, insurance, accounting etc. An owner, then, will be careful to seek an agent who has the ability to give successful management and an organization known for its ability and efficiency in handling real property.
