My first question is do you have any sort of signed buyers broker agreement with your current representation? If you do, you may be obligated to meet it's terms. In short, no agreement = you can fire your realtor. Now to address your representation...... if the agent is representing the other party, thats a limited agency relationship and should be disclosed. Have you asked him what his relationship is with that property? On the flip side, is the property he is pushing one that could meet your needs? It may be that after his examining all of what you are looking for and the time frame you want to accomplish this in, it may be in his opinion the best deal going, and thats why he is pushing it. Either way sounds like your communication and trust is not at it's best with your agent. I would suggest sitting down and laying out your concerns, including your thoughts on fireing him and looking for another agent. Short of a signed agreement, you should be at liberty to persue any property. If the agent has put in significant time and money in your commercial transaction, he may be entitled to some form of compensation. Without any signed agreement, this may be difficult to demonstrate.
