"JC was fabulous! I would highly recommend him to others. He was very knowledgeable and never tired of answering all my questions. I give him an A+, 5 stars and a two thumbs up."

           -- Ellen & Bill Diaz



"As a home stager, I have worked with many agents and JC was an absolute gem. I was very impressed with his level of commitment and extent to which he goes to promote a listing! He had great local knowledge, he was excellent in his interactions with the home owners, he always responded when I sent  texts or calls, and he found excellent buyers for the home. I was so impressed with him I have already recommended him to others!!"


          --Tristan Gary

"JC is honest and forthright with his clients. I enjoyed working with him on our quest to locate a condominium that we wanted. It took quite some time to locate the unit that we liked, I saw the listing on Friday night called J C on Saturday morning and looked at the unit on Saturday and the sellers ok'd it on the following Tuesday. We did not get in any bidding wars on this transaction."

          --Wayne & Carol Paul

"JC was very helpful in helping me sell my home. He was knowledgeable about the market in my specific area, as well as negotiating a reasonable sale amount. JC did a great job of guiding me through the sale process, consulting with me on the complexities of showing a home while living there, and ensuring a smooth transaction. He is a true professional and fantastic person. If I am ever in the market for a home in the Seattle area, again I know I'll be contacting JC and would happily recommend him to anyone."

          --Elizabeth Allen

"JC is committed to his clients. He helped us purchase our new home 4 months before helping us sell our house recently. What he doesn't know he is willing to research to get you the information. He is hard working, industrious, and is always focused on you when he is with you. We really appreciated his attention to detail, and he took notes of what we liked and what we didn't like. He is great at working with the other agents, keeping us informed throughout the process and negotiating. We appreciate his help navigating us through the complexities of buying and selling property in this challenging market. We certainly will recommend JC to our family and friends or anyone else seeking a real estate professional to accomplish their objectives."

          --Barry & Sherry Palmquist

"JC is a wonderful realtor who always understood my objectives. He worked hard and always kept the lines of communication open. From the beginning he was willing to show as many houses as necessary to find the right one. He never rushed me to decide on a home and was always ready to look at houses.  He also has a network of professionals that help to make the process quick and easy. He suggested a home inspector, the mortgage specialist, Title Company and even a handy repair man!! We used the people he suggested and everything went smoothly without any problems. I bought the home for the price I wanted and he was not afraid to negotiate for it. I can't say enough—choose JC as your real estate professional and you'll be glad you did."

          --Corinne Magnet

"The overall process of selling the house was done in a manner in which I am thoroughly pleased. I am very pleased with JC's staging recommendation and negotiating ability. He kept me informed during the process. He is very knowledgeable, honest and sincere—could not have had a more pleasant experience. I definitely will recommend JC to others when they are looking for a home or to sell their home."

          --Barbara Jenkins

"JC Gagnaire did a great job for us in a very short time. With short notice for a job relocation from Portland to Seattle JC was great—organized, prepared, attentive to our needs and listened to our objectives. We met JC at his office late afternoon on Friday after a long commute from Portland. He showed us 6 houses that night that required appointments to show. It was a late night, yet he met us early the next morning to show us 7 more houses.

As our Realtor, he helped us find the right house in the right neighborhood for the right price. Negotiating in this competitive market is not easy often with multiple offers exceeding asking price by thousands of dollars. JC successfully fulfilled our price expectations for our home by settling on a price below the asking amount.

We are very pleased with JC’s lender recommendation. We appreciate the mortgage consultant’s expertise and ability. His dedication and commitment to servicing his client's requirements, coupled with his mortgage expertise, make him unique in the industry and invaluable.

In short, JC was always on our side working to make our house purchase as simple and successful as possible. The best part about working with JC was that he was always more focused on answering our questions, giving us good advice, following up and finding homes that met our needs than he was on closing a deal.

We would recommend him to anyone."

          --Tony & Lisa Muilenburg

"JC’s knowledge of Seattle and surrounding area was helpful. JC was very dependable and always accessible if we had any questions about the home-buying process. JC was very straightforward, did not pressure us to buy, and was very keyed in on making sure we picked the right home. JC was very accommodating throughout the entire process, even when we had lots of questions. His main interest was making sure we were happy with the house. We would highly recommend using JC as your realtor. He will find your dream house and make the entire process delightful and easy to understand."

          --Nathan Lauer & Jennifer Ziegler

"JC is the best realtor we could have got. He was always patient and did his indent research before showing us the property. I have two small kids and he was always able to adjust his schedule to meet our requirements. I really appreciate the personal touch he added in the whole process. Even after we closed on the house, he recommended lot of good people to get work done in the house and overall we were very, very pleased by his service and would definitely recommend him to our friends."
