Helo Peter, You say you had a few homes in mind. Are they all listed by the same company? You ask if you should get an agent from another company. Unless you know which house you are going to buy, how will you know if the agent you get will not be working for the same company as the selling agent.
Speaking for myself and for the company I represent , you should still be represented fairley even if you end up with a dual agent. It is possible that a transaction could move very smoothly having both agents in the same company. I have been involved with this same senario. Even though we (the agents) are workiing in the same building we don't talk about our clients other then to present information reguarding the sale and purchase of the property. Having agents in the same building can also cut down on the time it takes to get information or answers for our clients. "WE" all want the same thing, the listing agent wants to get the sellers property sold with the least amount of concernes, in the shortest amount of time ,for the most amount of money. The buyers agent wants to get the offer accepted with the least amount of concerns, in the shortest amount of time, for the best value for their client. Some times the best value isn't the least money, but instead is a meeting of the minds for both the buyer and the seller. Often times the circumstance dictates the value, reguardless of agency.
