A realtor can be a huge asset and if yours is not doing his job to your satisfaction, fully explain to him why your not happy, what you expect and give him a period of time to step it up or show him the door. If you've never bought a house before, I say go with a realtor, find a new if need be but use one. One with more experience will go a long in finding the perfect place you looking for as well as explain process along the way...
