You'd like to hire an agent to sell yourhome without paying a commission. Then, you'd use the same agent to purchaseyour next home, and the seller would pay a regular commission, which youragent would share with the agent representing the seller. I don't know why an agent would agree to this, particularly since there's noway the agent can force you to purchase another home. If you decided to sell,and then rent an apartment or a house, the agent would collect no fee at all. I don't think this is the way you'd want to go.
Agents are professionals whoare motivated, in part, by their commission structure.
If you don't pay them,they won't want to sell your home. The time to bring this up is when you're interviewing prospective agents. I'ddiscuss this with them and then see who is willing to work with you to meetyour financial goals. Keep in mind that a lower commission does not meanyou've necessarily hired the best agent for the job, just the leastexpensive. Every Home Seller Should Ask.
