Carol Lynn Seifert was a patient and understanding agent during our search. She provided market driven knowledge and advice throughout all phases of the process from property search and evaluation to pricing and final offer. Her recommendation of a financing partner was most helpful and the financing principal (Claudio Prunotto) guided us through the financing process with skill and patience. The entire home buying experience was very positive thanks to the efforts of Carol Lynn.

Carol Lynn, went out of her way to make sure that we saw every house that she thought we would be interested in. Excellent work at getting us the house we wanted.

Carol Lynn always made sure I knew what was going on. She was VERY patient when I was not. Glad she was always available. When you have Carol Lynn and Krystle working for you, you have the best people on your side. I never worried that our place would sell. They know the business and take their expertise and use it for your advantage. A great team to work with!

Carol Lynn & Krystle helped me buy a new home and also sell my previous home. The process was daunting at first (to me), but they made it so easy and painless. Working with them as a team was great because one of them was always available. They both are so patient and knowledgeable. I had so much fun working with them, as well.

Carol responded to our initial inquiry in regards to having her come see our house within an hour, came two days later. She and Krystle returned with their presentation two days after that.

Carol and Krystle were knowledgeable, accessible, professional, and helpful from our initial exploratory contact through closing. We were moving out of state and Carol interviewed realtors and made a recommendation (who was amazing!) in our new city. When our timetable for selling the house changed a couple of times, Carol and Krystle were flexible and responsive. Our house was on the market quicky and sold fast as well. We highly recommend cArol and Krystle!

Carol Lynn and Krystle got me the perfect condo. Thanks to their connections, they were able to show me a very spacious place for my price point before it was even listed publicly.

Also, their knowledge and experience got me through some difficult times during closing. Even though the lender I chose gave me some scares, I was able to get through it with confidence knowing that I had Carol's team to back me up.

Carol Lynn Seifert and Krystle King made the selling of a second home as efficient as possible with their 24/7 support and thorough engagement with us every step of the way. We never had to worry about any part of the process because we knew that the Seifert & King team would support us along the way! Thank you!

My husband and I were thrilled with the ease and comfort of working with Carol Lynn and Krystle on both the buying and selling of our homes. From our first meeting to the closing on both properties, both ladies worked tirelessly to make this stressful process run as smoothly as possible. They advocated for our family and needs when necessarily and always answered our questions and eased our concerns in a timely manner. We couldn't recommend anyone better than this dynamic duo! Thanks for helping us find our forever home!

She came highly recommended from a friend who had used Carol Lynn to sell her property and was impressed with her business acumen

Everything went very smoothly. She was very responsive

Krystal was just as responsive, knowledgeable and friendly as Carol Lynn

I have moved 6 times and this was the best experience yet
