We had a great experience working with Penny O’Brien to sell our home. We initially listed with another agent, but unfortunately the home was not marketed or positioned as effectively as we had hoped.

After switching to Penny, the difference was immediate. She quickly assessed the situation, gave us practical and thoughtful advice, adjusted the pricing and marketing strategy, and gave the listing a completely fresh look. The new photography was fantastic and really helped showcase the home.

Most importantly, we received an offer within just one week of the new listing and closed within three weeks. We really appreciated Penny’s responsiveness, professionalism, and ability to make the right adjustments quickly.

Selling a home can be stressful, especially after a disappointing first attempt, but Penny helped turn the situation around and made the entire process smooth and efficient. We’re very happy we made the switch and would highly recommend Penny to anyone looking to sell their home!

Penny made the entire home-selling process smooth and stress-free. She helped us sell our house quickly while remaining professional, knowledgeable, and responsive every step of the way. No matter how many questions we had—or how complicated they were—she always took the time to explain everything clearly and made us feel confident throughout the process. Her expertise, dedication, and commitment to her clients truly set her apart. We couldn’t have asked for a better real estate agent, and we wholeheartedly recommend Penny to anyone looking to buy or sell a home.

Penny did an awesome job. We listed our home on Thursday and had offers by Sunday. Very pleased with her attention to detail and professionalism. We highly recommend Penny.
