Karen was friendly and helpful regarding the houses I specifically wanted to view, and she was knowledgeable and helpful regarding the process of buying a house. Here's the "however": I explained to her specifically the style, size, budget, and locations I was looking for in a house. What I got instead were many emails saying "Here are some houses that I think you'd like" with virtually nothing relevant to my preferences, aside from the rare occasion. It was as though she'd put me on a mass mail list to try and offload what she'd been sitting on for a while. It made me wonder if she'd even been listening to me.
Karen is a friendly person and I enjoyed looking at houses with her, but don't expect her to help you FIND what you're looking for.
