Karen Tanzer is a very knowledgeable, intelligent and caring realtor. My husband and I felt we could trust her completely. We never knew anyone who was as devoted to her job, and put in as many hours as she did. We always knew that we could count on her. She let us know exactly what we needed to do to sell our house. Whenever we ran into a problem, she would find a solution. She sold our house quickly, and for a good price. We highly recommend Karen.

We cannot recommend Karen highly enough. As first-time home buyers, we started the process unsure about what to expect. Karen changed all of that from day one.

She was incredibly patient, helpful, and guided us expertly through every single step of the journey. What we appreciated most was that she didn't just show us houses, she taught us what to look for and helped us understand the right questions to ask—things we never would have known to consider on our own.

Her guidance was invaluable, and she was always available to answer our (many) questions, making us feel supported and confident in our decisions. We truly felt like we had a trusted advocate on our side.
If you are looking for a realtor who is knowledgeable, dedicated, and genuinely cares about her clients, look no further. We would recommend Karen to anyone and everyone, especially other first-time buyers! We are so grateful for her help in finding our perfect first home.

Karen and Seth were wonderful to work with. They were always available when I had questions and walked me through every step of the house buying process. They are both truly wonderful and kind people and we were very happy to have them as realtors
