For Kevin, Lake Oswego and the Portland metro area are not just a place to do business. They are the place he calls home—a commitment and sentiment he brings into every transaction.

Hasson Relocation, Masters Circle

Kevin Costello has consistently performed beyond our expectations. Over the years he has located properties that were ideal for us, and due to his sound advice, our offers were accepted even in multiple offer situations.

When it comes to buying or selling a home in Lake Oswego, Kevin has our vote. He never promised anything that he couldn’t deliver. We would absolutely recommend him.

— Henry and Pam Moss

In spite of a down economy, we had a successful sale of our home thanks to Kevin’s energy, enthusiasm, knowledge and experience in the industry.

— Ken and Jan Lewis

Kevin showed us how easy and painless selling a home can be! He knows the market so well that he was able to price our home to sell quickly. We received multiple offers which he helped us sort through and then brought the deal to a close.

— Jeff and Sydney Higgins

Our experience with Kevin was great! We were relocating and each time we came to town he had lined up homes to show us that fit what we were looking for. He took the time to understand our objectives and worked behind the scenes to maximize our time during the process. He also went out of his way to make sure we were familiar with the what the city of Lake Oswego had to offer. In addition, Kevin was creative in negotiating a price that allowed us to buy a home that was originally out of our budget. We would highly recommend Kevin. He brings professionalism and knowledge of the market that was invaluable to our decision making process!

— Jeff and Diana Scott

We were certain that Kevin had our best interests at heart when we sold our home and subsequently bought another one. He was enthusiastic, positive, warm, and available. Whenever we had concerns or questions, he or his assistant was quick to help.

— Dennis and Anna Stone

While Kevin is a professional, he has a personal style that is easy going and fun to work with. His recommendations are based on years of experience and market research but in the end, he allows you to make the decision that works for you. He is flexible in his approach and open to ideas, which in this market can often make all the difference in closing a deal.

— Steve and Carrie Elliott

Jeff and I are truly grateful for the “take charge” actions you demonstrated to sell our home! It was a pleasure to work with you and we were confident in your abilities to get the job done. Thank you for all your hard work. We will tell anyone selling a house in Lake Oswego to list with you.

— Jeff and Karen Bartlett

Kevin has helped us with four real estate transactions—two sales and two purchases. His experience, insight, and professionalism were invaluable each time. When it came to selling our home, he guided us in how to price and present it so that it sold quickly. During the house hunting process, he was very patient, showing us countless homes as we searched for the perfect one. On the purchasing side, he was there guiding the transaction along each step of the way. His network of support proved to be top notch and his calm demeanor is just what the homebuyer needs because the process is not just a financial one, but an emotional one too.

— Chris and Kathi Hermanski

Jeanne and I have purchased two homes with Kevin and each time we have benefited from his knowledge of the marketplace and his ability to listen to our needs and desires. What better proof of our satisfaction with his service than the fact that we have recommended to him to many of our friends and family who have also ended up as happy homeowners.

— Mark and Jeanne Sipiora

We found Kevin to be a true professional--he was a good listener and acted on behalf of our needs. When selling, his experience and knowledge of what buyers were looking for allowed him to help stage and prepare our home for sale and as a result, it sold quickly. On the buying end, we were looking for a home on Oswego Lake, and again, Kevin's experience in waterfront property helped guide us in making the right purchase. Ours was one of multiple offers on the house, but his experience in negotiations helped ours win out! We will use Kevin the next time we have the need and would recommend him to anyone.

— Phil and Nan Bird

Kevin is the hardest working and best Realtor on the planet. Not only does he bring honesty and openness to every real estate transaction (and we’ve had quite a few with him) but he also has the experience to back them up and make them run smoothly. We know when we’re working with Kevin, we’re getting the best advice that’s out there to guide us in our next move. No wonder we are his biggest fans!
