Hmmm, interesting.
With the advent of the internet, it is indeed true that if you're using the correct website, you can see all the same houses for sale and under contract as we do. If you've got a subscription to the right site, it'll even provide the sold information. Note, there are multiple "right sites", not just one.
The Realtor's job is not to "find" the right house for you, but to help you find the right house for you (since you'll be living in it, not them. You have to be happy, not me).
As for schools, I consider myself an expert on the schools my children attend. I'd say that have "expertise" in all of the schools that my clients' children attend, because I can get their honest feedback on those schools. I'd also say that I have more expertise in looking at schools for their real evaluation beyond what "great schools" can tell you. And what I'd point out most of all is that there are about 120 elementary schools, 40 of which are probably fantastic, 40 more which are perfectly acceptable, and 40 more which need help. I'd also point out that don't buy a house in the Triangle - IN YOUR PRICE RANGE AND SIZE NEED - based upon the school. Because you'll be buying in a region that has higher growth and the need to build new schools and reassign families. You might be at your school for 2 years, 5 years, or 20 years. But there's about as much guarantee of school assignment as there is career employment at IBM.
lastly, on schools - we are going to present you with the information ... whether you have or can find it yourself ... and let you decide. Because if I tell a client "you can't miss going to that school!" and either the asssignment, the principal, heck the PTA leadership changes - who ya gonna blame? Yourself, or me?
