I think you want to think about what questions the realtor asks you; how much do they want to know about you before helping you find the right home. It is important to sit down together and have a discussion about your needs, wants , likes, must haves, must not haves. The focus is on you, not them. You need to feel comfortable that they will do their best to help you find the right home, and that they have the skills to bring you back on track if you lose sight of your original intent. There is a lot of inventory, you want a realtor who will not waste your time looking at everything that might possibly work for you.
