No, Patricia - that is not true - it is not the "norm" in this area - it was many, many years ago, but it hasn't been the case for a very long time.
We really have to be careful when we generalize about business practices out of our local area, or it could be confusing to a consumer.
Ed and Allison gave correct answers..
Commissions are always negotiable as well as the purchase price and the security. Be careful and make sure you have an agent willing to negotiate for you. Please remember in general a rental commission is paid by the Land lord and is generally the first months rent split between your agent (who found you the property )and the agent who put it on the market. It is not paid by you to the land lord or the agents.
