Hi, I'm Mary Ann!
Mary Ann Cadorna Realtor Broker Owner Sincerity Realty ® “A Sincere Voice For Your Real Estate Choice.” Sincerity is the absence of deceit, hypocrisy and pretense. Mary Ann.Realtor is sincerely just that. After two decades of being with the big box brokerages and their transaction trenches, I saw a need for sincerity in the business of homes for sale. And so, I offer a caring, more personal, and honest approach. As a result, I decided to stand up and step out on those values and became a full-service Broker-Owner and Sincerity Realty® was born. I make the home buying and selling experience transparent, thus making it easier to understand and navigate. I offer a unique and holistic approach, along with my guidance, and support, so my clients feel safe with complete faith in my representation. They have full confidence knowing I am there for them every step of the way! Saving sellers time, stress, and money, and getting my buyers the best home, best location, for best price. So much so that I’ve helped over 100 people become first-time homeowners, and clients have returned for my services 10 and 20 years later. If you just want straight forward honesty, with 23 years of exemplary reputation, and Five Star Award Winning Service, A+ Rated by the Better Business Bureau, all you have to do is call me directly at 628-888-9078.

Mary Ann Is The Right Realtor ® For You
I’ve had the pleasure of knowing Mary Ann 20 years. I’ve always known if I were to buy another home Mary Ann would be my realtor, and 20 years later Mary Ann helped my husband and I buy our dream home. The kindness, honesty, and love she has for people is genuine. Her goal is for her clients to buy a home they will be happy in. She is not in it for the $. Mary Ann’s joy comes from her buyers finding their forever home. Mary Ann is relentless and works hard for her clients. I won’t say how many homes she showed us, but it was manyyyyyy and she was always excited with a smile on her face. The thing I also really like about Maryanne is she is not pushy and was a second set of eyes for us. She would notice things on a property I had not seen and tell me. I truly appreciated her honesty especially when so many other realtors only care about making a sale. Mary Ann makes you feel like family and is such a beautiful person. I trust her 110% and if you are looking for an honest realtor Mary Ann is the right realtor for you.
We truly love and value Mary Ann
Mary Ann was an amazing realtor for us. She leads with her heart and was 100% committed to getting us our home. As first time home buyers, the process was daunting but with her caring heart and knowledge of the real estate business, we knew in time she would find us the right home. There were many times where we felt defeated and did not think it was possible to purchase a home in this current market but Mary Ann was with us every step of the way in our journey and made us believe it could actually happen. We truly love and value Mary Ann and everything she did for us to make our dream of owning a home a reality. Nadia, Concord
