Everything about Liz and her knowledge is amazing! She is honest and very forthcoming both when buying and selling. I feel like I’ve had a parent by my side the entire process of both buying and selling a house. Liz ensures that you are supported through every step of the journey and always has your back. I would recommend her to anyone and everyone.

We recently sold our rental property and had the absolute pleasure of working with Liz Kostroski. Not only is she a wonderful friend, but she is also an amazing real estate agent—professional, knowledgeable, and incredibly supportive throughout the entire process.
She is truly honest, trustworthy, and always had our best interest at heart. From start to finish, she made everything smooth and stress-free, handled every detail with care, and communicated clearly and promptly at every step.
If you’re looking for someone who genuinely cares about her clients and knows the market inside and out, I can’t recommend Liz enough!

Liz is the best realtor! This is the third property I’ve either bought or sold with Liz. Every experience has been amazing. She makes selling and buying a breeze. She is knowledgeable and quick to respond. She advocates for you but never pressures you. I will recommend her over and over again.

We have worked with Liz for several years, Seven years ago she helped us purchase our first home, as first time home buyers we were very uncertain of the process, cost, and necessary events that go into this life change. Liz expertly guided us along the process, discussed state law, was available for showings, and always had us in mind. Around 30 days ago, we notified her we wanted to try to purchase our dream home and leave our existing one in the care of another buyer, she was immediate in her response. In only 2 x weeks we had accepted a offer to sell our home and also had been approved on our dream home! She is amazing and so caring with our lives. Truly a pleasure!

During the past five years of knowing Liz, she assisted my husband and I with buying and selling our two homes. She always kept in touch with us by phone or email, keeping us informed every step of the way with anything we needed to know. Liz was sweet, courteous and always professional when it came time to answer any questions my husband and I had. Liz always made sure we had all of the correct information, that we understood the forms before we signed them and made sure everything went smoothly. My husband and I always felt good about our experience with buying and selling our homes because we had Liz in our corner. Thank you, Liz, for everything. You're the best!!!
