Testimonials
"
Our realtor was wonderful to work with throughout the entire process. She was incredibly patient, always took the time to answer our questions, and guided us through every step with professionalism and kindness. She made what could have been a stressful experience feel much easier, and we truly appreciated her support. We would highly recommend her to anyone buying or selling a home.

Mary is a gem! We sold our home and built a new home with her and her expertise in the building process was truly priceless. She helped us navigate the areas we weren’t familiar with and are so thankful for her guidance. We adore Mary!!

Mary was fantastic from start to finish. Very friendly and professional. Gave us expert opinions that helped us buy and sell our home. I will definitely recommend Mary as I already have to others. I wouldn’t use anyone else.

Mary treated us like family throughout the entire home buying process, from the house hunting stage through the closing process (and after). This was our first home purchase, and Mary took the time to explain everything in detail so that there were no surprises! Her experience and expertise in real estate is top tier and we were able to locate and purchase our first home seamlessly. We were nervous at first after hearing stories on how hard buying a home can be from friends, this was not the case with Mary as our realtor. She was pragmatic and proactive, addressing everything in advance so that we were able to be ahead of the game going into close. We couldn’t have done any of this without her knowledge and wisdom, and we couldn’t be happier! Please use Mary at Rinehart Realty, we have never been happier in our new home and you won’t be disappointed!

We are so grateful to have worked with Mary. Her calm and genuine personality made looking for a home more relaxing- even when we had to bring our young children! She was there to answer any question or concerns we had in person or over the phone when needed. She took a lot of stress away by asking questions for us and making this whole process smooth. Her incite on real estate and the Lake Wylie area and involvement in the community made it a no brainer that we chose the best of the best to help us buy our family home. We can’t thank Mary enough. She was a delight to work with and to be around. We would recommend her to anyone looking in the lake Wylie area.

We had a excellent experience working with Mary. She was there throughout the whole process , from start to finish. She always kept us informed about every development, answering all our questions. You could clearly see her expertise in the ability to clearly explain complex contract details. She went above and beyond helping us with all details. I would highly recommend Mary.

Mary was awesome. We were a bit challenging in that we had about three days to look at houses in person, and then we made an offer and went back home (to IL). She managed things for us, made sure we were on top of our paperwork, answered all of our questions, and gave us great referrals. She also went above and beyond with FaceTime " visits" to the house for us, working with the builder, and even taking our water sample to be tested for us! We really like her and she is an AWESOME realtor. We will absolutely recommend her to anyone in that area who is looking for a realtor. She was great!!

Mary Sieck is a top notch agent! She has been both a listing agent and selling agent for me and my husband and in both cases she really went above and beyond! We are living in Bluffton and she previewed a house we liked (and ended up buying). She truly earned her commission on this house and thank her from the bottom of our hearts for all the work she did! Mary takes her job very seriously and it shows in the way she handles everything from the transaction details to the end of the close! Thank you so much Mary for all your help!

Mary was wonderful to work with and did everything in her power to get our house sold and for the best price! She has a very nice way about her that makes you feel comfortable with her. She is obviously very interested in her job and making the most of all that is available to increase her business. I was a realtor for over 25 years in Boston and then 10+ years in Scottsdale, so I have been involved in the business for many years and met many agents. Mary was right up there with the best of the realtors I have known over the years....

Troy, please take this time to review my services while selling your home. Greatly Appreciated. Mary, did an outstanding job selling my property. She was very knowledgeable and attentive as well as always being there whenever I would reach out. Thank you SO MUCH Mary!!!!!!

This is our third transaction with Mary, and as long as she's available to us, we'll never use another Realtor. She is truly the best in the business. No offense to anyone else in the industry, but in a world full of part-time, amateur "real estate agents", Mary defines the word "Realtor" and stands head and shoulders above her peers. It's not often, in any profession, that you can find someone as genuine, knowledgeable, hard-working, and tenacious as Mary Sieck. She earns every penny of commission that she's paid...and then some!
