I agree, don't pick someone just because they are on the same message board. You definitely need to make sure that you interview Realtors as these types of transactions are some of the largest you'll ever be involved with. Truth is in the numbers, and eveyone's wants and needs are different. Our team does real estate full time, we are going to do everything we can for you because if we don't, then there goes our lively hood. Don't pick someone just because they are referred to you, interview them and see if they fit you. Something I would recommend is doing a search on google.com for questions to ask a Realtor, "Interview questions"
Whatever you decide, make your decision an informed and educated one. I wish you the best in your home buying venture!
