Hey Danny, Are the agents that you are calling initially in the market area where you are looking to buy, or are they elsewhere and referring you to another agent within their company for a referral fee? If so you might want to find your own agent by other means. Some of the ways I look for agents it to research sole properties in my intended market and see who those listing agents were. You could contact them and they might be better able to represent you a a buyer's agent, or refer you to other good reputable agents in the area. You might also look for agents who are also investors that would have a better fix on the area, but you might find them to be in competition with you for property. Downside.
You definitely want and agent who works for you so if they are not available to show you property whenever you can view it is not a good sign. How quickly they respond back to you is also a good measure of their hunger to get you a deal. Finding a good agent makes a lot of difference in a successful purchase so go with your gut and ask good questions, get referrals from them. Good luck. Wade
