Excellent Overall Experience

Excellent Overall Experience

Jen was great to work with. She is super thorough, trustworthy and a great communicator. She valued our opinion and helped guide us through the house selling process step by step even while on vacation. She went above and beyond to make us comfortable, guide us through some processes, and gave excellent advice working with a complicated HOA. When it came down to pricing I think she hit the nail on the head. She was great at comparing property value to help us get over asking for the house while remaining competitive. I would recommend anyone that is looking for a realtor to go and work with her.

Jennifer is the best realtor and she always made sure I was supported throughout the entire process!

Jennifer is the best realtor and she always made sure I was supported throughout the entire process!

Jennifer was everything I wanted in a realtor! She helped me sell my condo and find a new home to buy. From the first conversation, Jennifer was welcoming, got to know me and what I wanted in a home, and it was abundantly clear that she is an absolute expert in strategy and ensuring her clients have the best service. Jennifer always made me feel like my dreams of buying a single family home were never too big and she would make sure I had the opportunities to find exactly what I wanted (which I did!). I felt supported the entire time through the process of selling and buying, and Jennifer would always answer my questions and explain everything to me. She provided great resources to me throughout as well. Jennifer went above and beyond for me and I couldn’t ask for a better realtor! I am incredibly thankful to have worked with Jennifer, she is the BEST & has a wonderful & helpful team as well - highly recommend!

If you are looking for the absolute best realtor, look no further because she is Sydney Be kman!

For background, we have bought and sold 10 homes throughout our lives, and our experience with Sydney was hands down fantastic. She is the best realtor with whom we have ever worked. She is professional, extremely knowledgeable, and always pleasant and reassuring with any concern. Her network of contacts is absolutely impressive. She provided sound advice in regard to staging, pricing, and how and when we should conduct showings. Her marketing skills are unsurpassed - the photography of our home, which was used for the website and the brochure, was exceptional. Sydney was extremely responsive and she remained willing to answer any question throughout the process. We can't say enough about Sydney's talents and her passion for her work. As stated above in the title, if you want the best realtor who is engaging and results driven, while ensuring you are always kept in the loop, look no further than Sydney. With gratitude for her efforts, Michael and Mary Overfelt
