“Karen was exceptional in the sale of my mother's home of 60 years. She was very knowledgeable about the local regulations and also had the contractor contacts needed to ensure the house met them. She did an amazing job preparing the property for the market, and the number of offers received clearly demonstrated she knew her stuff. She was in regular contact throughout the process and I never felt like I was pursuing her for information. I always had what I needed when I needed it in order to keep things moving forward. In the end we had a very successful and relatively straightforward house sale. I would highly recommend Karen's services to anyone looking for a realtor in the local area!”

“Karen was an outstanding agent - very knowledgeable and gave us great advice which resulted in a quick sale for a great price and terms. Karen's experience was evident through every aspect of the transaction. She previously worked with our first time buyer son and helped him through a challenging purchase. We are experienced buyers and sellers yet still had questions and she was just as patient and understanding with us as she was with our son. She handles all situations professionally and calmly. I wouldn't hesitate to recommend Karen!”

“Barrett Sotheby’s flexible, cooperative work with another company is admired and appreciated. Karen Wallace’s work ethic, personable character, and flexibility made life easy and manageable. My husband John died. I moved to an assisted living apartment. We needed good, well known, local care in the sale of our home of 36 years, since 1963 for John. John, Jr. managed the sale of our home with Karen Wallace. Excellent care. Prompt sale. Wonderful business experience. Thank you. Patricia E Gerty ( Mrs. John M. Gerty) 1-20-22 Thank goodness for such excellent people.”
