Karen MacMillan was our real estate agent in our recent purchase of a vacation home in PEI. She has been fantastic from the very beginning. We are new to homeownership in PEI as we live in Ontario and we had many questions about the process. Karen has always been very prompt and knowledgeable with answers to all of our questions. She has gone above and beyond many times in this process, helping us to find local cleaners, repair folks, carpenters, etc. She was always very prompt in her responses and positive in all of our conversations. We would highly recommended Karen to any of our friends and family. She has been truly excellent.

Karen was great to work with. We appreciated that Karen was never pushy - in fact, she was quick to advise us against houses she knew were a poor fit! She respected our budget - we never felt like we were being pushed to buy something outside of our price range. Karen was also very patient with us - she showed us almost 20 houses before we finally found the one we now call our home!

Karen gets things done! Any questions or concerns I had with buying my first home she was right there every step of the way. We are so grateful for her expertise in helping with the home buying process.

Ida Mitchell

Karen is very energetic and gives good advice for staging a home. She had excellent pictures and videos taken. Good knowledge of local market values. She did well with finding prospective buyers. Had several offers very quickly.

John Kennedy

We selected Karen as our Realtor because of the reviews from people moving to PEI from other provinces. Karen was helpful, patient and understanding. We were searching for a retirement property with a litany of requirements during a global pandemic! We were not permitted to come to PEI to view properties, so we had to rely on Karen to give us her candid opinion when touring homes on our behalf. While we walked through the properties with her on Facetime, we couldn't get the "feel" of the house you get when viewing it personally. We asked her questions about the smell of the house, cleanliness etc... She was honest and we very much appreciated her integrity. Karen was able to negotiate a fair price on a property for us; she agreed to be our sponsor during our mandatory self-isolation and even offered to pick us up groceries. Karen was interested in helping us buy the right property, not just selling us a house. We have now moved into our home on PEI and WE LOVE IT!

I would like to take this opportunity to say how much we appreciated the help and assistance we received from Karen MacMillan of EXIT Realty in our move from Quebec to P.E.I. Not only in the negotiation for the purchase of our house in P.E.I. but also the support she gave us. Our move became more stressful when the moving company that handled our furniture advised us they would be 2 days late in arriving which put us in the awkward situation having to start our 2-week quarantine without furniture and food. At that point we did not know what to do. That is when Karen stepped in to save the day. She contacted family members close to where we were and they dropped off an inflatable mattress as well as pots and pans. They also contacted the local Co-op to deliver food to us so we could get through the quarantine period. These kinds of actions go above and beyond the responsibility of a real-estate agent. We appreciated all of Karen's efforts and wanted to share our experience with you.

Michel Ethier

Home buying is a very stressful time. It’s also quite an intimidating experience if you don’t know what you're doing. Karen made everything so easy and slick. She took care of everything and was very easy to communicate with. You could call or text her anytime and she would answer immediately or reply within minutes. I’m very glad we had Karen dealing with us and will definitely be asking for her again in the future.

Mike O'Halloran

I have used many Realtors in my life, and the service from Karen MacMillan at EXIT Realty PEI has stood out as beyond exceptional. She truly cares, and this is a rare quality. When we arrived and things weren't as they should have been left by the seller, Karen quickly pulled her resources together, helped in a multitude of ways and got us in and comfortable very quickly on a holiday weekend. It takes a lot to impress some people, but Karen will leave a lasting impression as professional, caring, reliable, and a good person in every way. There is a quality that is hard to define in words, and Karen has this special quality. A rare gem as a Realtor and a person. I so appreciate working with her.


Karen is an exceptional agent. Day or night she was always available to answer our questions. So far, we have bought two houses from her and we highly recommend her. She truly has our best interests at heart. She kept reassuring us that we would find our perfect home. Her dedication and her joyful personality made everything easier for us. Karen, we thank you from the bottom of our hearts. You are truly the best agent a person could find.

Caroline Foucher

Karen is a great real estate agent. She made my transaction extremely smooth and quick and seamless. I would highly recommend using Karen again myself and would highly recommend to anyone to use her because she gets the job done.

Roger M

We were on the fence for so long to buy another home. We didn't think we could get enough out of the sale of our old home but she helped us get it ready to sell. We were so stressed but she helped us the whole way through the process. She was easy to reach at any time. Karen goes above the rest when it comes to buying and selling. She works hard. More importantly, she works for you!

Shauna Arsenault

We had our house listed with Karen in 2018 but it did not sell at the time. Karen stayed in touch with us and in August contacted us to see if we were still interested in selling. We advised her of all the upgrades we did and what we were looking for in order to sell. Karen called us on a Monday, called back on Wednesday and on Friday our house sold! 5 DAYS!! We were so happy Karen had stayed in touch with us. The professionalism and dedication to her purchasers and sellers is out of this world. Karen is dedicated, honest, hardworking and very knowledgable. We then bought a house from Karen in Summerside. In early December, she showed up at our house with a big Christmas bag full of homemade goodies! WOW! Not only is she a fantastic REALTOR but a professional baker as well! Karen would be an asset to any real estate firm!!

Bev McKay & Gerry Gallant

Karen MacMillan was an amazing agent, went above and beyond through bumps in the road to get us to our property closing.
