Ask Cortney McKenna


Without Cortney as our agent, I don't think my husband and I could have navigated all the uneasy feelings that come with being a first time home buyer. She worked very hard to provide us with many different options, even when we weren't 100% sure what we wanted. Cortney was personable, deeply knowledgable, and always provided us with prompt answers to our millions of questions. She navigated our situation with ease and because of her we have the best first home we could have ever imagined!

- Taylor and Brett Loehr

During the lowest time of our life (the loss of our daughter), Cortney made the selling of her house an easy and painless process. We are indebted to her for her compassion and professionalism.' We love you Cortney!'


Being first time home buyers my husband and I were more than a little nervous. However, Cortney treated us with the love and care of a family member. She made sure to listen to our wants and needs and somehow managed to help us find the perfect home, despite the fact that she was 9 months pregnant! She was so kind and an absolute joy to work with. We could not have possibly had a better experience.


Cortney made the experience of purchasing my first home fun and meaningful. Her work ethic and knowledge of the industry are unmatched. I will always work with her for all my real estate needs.


We can not put into words how truly grateful we are for Cortneys help with the home buying process. Of all the decisions we had to make she was by far the best. It was an absolute dream to work with Cortney and we hope she enjoys being busy because we will also recommend nobody but her!
