Karen Glowacki was a professional through and through; always there every step of the way to answer questions, provide guidance, follow up on needed areas and always with care, compassion and integrity! Her experience and knowledge carried us to full fruition in selling our home. We were able to see first hand how accomplished she is compared to many other realtors. This vital aspect of selling a home if using a realtor can’t afford to use anyone less qualified; not just financially but emotionally and mentally as well. It’s VERY important! We would hire her again and highly recommend her.

Karen was referred to me by a neighbor and I can’t put into words how lucky I feel. My mom is elderly and I needed to sell her condo and relocate her back to Iowa with me. Logistically, this was an issue as everything had to be handled remotely as we were Iowa when trying to list and sell. Karen was unbelievably helpful and on the the ball from the start. She was instrumental in helping us get to closing at the price we were hoping for. Her guidance from what we should or shouldn’t do before we put the condo on the market was spot on! Her referral for a real estate attorney was also a home run as he was amazing. I had so much on my plate and working with Karen was therapeutic. She took so much stress off my shoulders and really made things happen. We certainly weren’t the biggest sale of her career, but you would never of known that from the time and effort Karen put into helping us. Thank you again Karen. You are a Rock Star!
