What Our Clients Say

"Our first experience with Regan Kane and John McDonald Realty was several years ago, when we purchased our lot. He was the consummate professional and when we asked for referrals on potential contractors, he provided us three and we used one and was extremely happy. When we decided to sell our home, there was only one person who we would use-Regan. His professionalism, knowledge of the market, years of contacts and his genuine demeanor made him our only choice. In short time, he found a buyer and he found us another house and lot. He considered the value of our time and coordinated all the closings on the same day, which made it so convenient for us. "

- Eric and Kelly

"Stephanie was a pleasure to work with when selling my home and purchasing my new home. She was always available to answer any questions I had and if she didn't have the answer, which didn't happen often, she was quick to reach out to the right source and find the answer. She was on top of all the new listings that came on the market and kept me abreast of new ones in my price range. I would entrust her to selling and help me to purchase my next home when the time arises."

- Maryann Rozier

"We were thinking of relocating from Kentucky and the week of Thanksgiving 2018 we drove down to evaluate communities in Louisiana and Mississippi. The day before Thanksgiving we came to Bay St. Louis, saw a house that interested us and called the realtor, John McDonald Realty. Even on such short notice, their representative, Aissa Wiggins, said she would be glad to meet us and give us a tour of available properties that would fit our particular budget, as well as the community. It could not have gone any better! Not only was she very knowledgeable and professional about the community and the properties, but in a short amount of time, she understood exactly what we were looking for. We found a property that day that we fell in love with and shorty afterward, we purchased it. Aissa's assistance didn't stop there. We were making a long distance move, and she assisted in so many ways to make our transition smooth and seamless. The personal, sincere touch was so important to us, and I would highly recommend John McDonald Realty."

"They say that first impressions are everything. When we first met Mary, we could tell immediately that she was a professional, yet very approachable. Our connection was instantaneous as we discussed what we were looking for in a home and the area. Mary was extremely knowledgeable of the homes and property in the areas we were interested in looking. She was always aware of the importance in balancing what were looking for and our budget. By really listening to us she was able to fine tune properties to show us which helped streamline our buying timeline. Once we found our dream property, Mary walked us through the offer, contract and closing process. Would we work with Mary again? Absolutely! She’s the best! "

- Beverly and Mike Cummings

"We would to thank our realtor, Brian Necaise, for his unending hard work in helping us with the recent purchase of a first home for our grandson. We have known Brian since he was a young boy, and he has become a very talented and dedicated realtor. He has an impeccable work ethic, which is very rare these days. If he said he was going to do something, he did, and in a very timely manner. We sincerely appreciate Brian's time and continuous effort in helping us making this purchase so easy! "

- Al & Vicki Arnold

"Jeanne, Thank you so much for being the best realtor ever! You made the home buying process easy, fun and exciting and we are so thankful you we’re on duty the day we stopped by! Thanks for being such a blessing in our lives!"
