About Kathleen

Kathleen has been successfully representing clients in the sale and acquisition of residential, investment and commercial real estate for 49 years while owning Mueller Realty for 41 years. She has learned that one of the most important aspects in life as well as business is ones honesty and integrity. In such a competitive business as real estate, it is important that your agent believe that their clients needs and goals come before all other considerations. Kathleen wholeheartedly believes this and follows this premise in every transaction she handles and with every client she represents. Whatever the market we are in, a successful transaction calls for an agent willing and able to go beyond the traditional - the manner in which Kathleen cares for and deals with her clients and their properties, is definitely a step above the standard!

Kathleen is AMAZING! She has helped our family three different times and I highly recommend her!! :)

Responsive Above and beyond! We saw a house unexpectedly that was prfect but they were already reviewing offers and my mom's house was not even for sale. With Kathlenn as our agent we got the house!! We had to move fast to make this happen. Lots of negotiations, decisions, tasks and securing other parties needed, had to be done quickly. Kathleen had a lot of timely challenges and made it happen. Communication Perfect! She is Always quick on responses. We corresponded with phone calls, emails texts and in person. I appreciated being able to rely on several different ways to communicate. Negotiation Kathleen successfully helped us with 4 houses! Buying two and selling two over three different occasions and a span of about 20 years. There were challenges with each house but Kathleen was able to navigate them all and make it happen for us. Professionalism Kathleen helped my mom and I with her new house with 100% professionalism. She understood and walked us thru the Many challenges from the beginning. I aways felt comfortable asking Kathleen questions and discussing everything from A to Z. With her expertise, she was always on top of all the scenarios expected and unexpected. It was so important to be able to trust her because purchasing a house is stressful enough. Strong Market Knowledge Kathleen has Years of experience and Knows her market. Two of the houses were directly in her area and two were in other cities but Kathleen always does her research and understood the markets in all locations. Stands Out We have relied on Kathleen four times because she is the BEST! She gets the job done. She truly cares, is honest, smart, reliable, friendly and knows what she's doing. My house and my mom's new house seemed like impossible dreams but with Kathleen, those dreams came true. I highly recommend Kathleen Mueller! :)

Outstanding Performance by extremely knowledgeable, experienced, helpful and responsive Realtor!

Always responded quickly to all questions. Compassionate and respectful of our longtime family home. Provided detailed, easy-to-read reports in writing and verbally about the market, listing price and offers received. Clear guidance related to negotiations was fantastic. Use of electronic forms was accomplished without problems. Addressed repair issues with experts known to her, which was a BIG help! Showed respect for the buyers and their agent too, which exemplifies Kathleen’s professionalism. We HIGHLY recommend her services!!
