This was our first time working with Christine and we would highly recommend her to anyone we know who's looking for a real estate agent. My husband and I appreciated her knowledge and professionalism as well as her positive perspective and yet no nonsense. Communication at all points was excellent.
Thanks Christine

Selling your home can be very stressful, so having a agent who clearly knows all the ups and downs that take place during this process is very important. Our agent made sure we got a honest and fair contract. We were very comfortable and confident with her work. I would recommend Christine to everyone selling a house.

Highly recommend!

As a first time home seller, Christine put us at ease and made the process seem easy. She is very professional and a fantastic communicator. I had a lot of questions and she never made me feel like I was bothering her.

Christine is Fantastic to work with! She was both buyer and seller agent for me, and helped me through every step of the process. Christine was easy to get in touch with, every time I had a question or worry. I would recommend Christine to anyone who is looking to buy or sell!!

I can't recommend Christine enough as a realtor! From the start, she was professional, detail oriented, positive, and worked her very best for me and the sale of my home. Her approach is confident and in control which made me feel at ease the whole time. My only regret is not having her as my first agent. She came in after my house had been on the market and completely changed the game to get my house sold. You want her in your corner and I will refer her to anyone who asks for a great agent!

Christine was amazing! She is professional and maintains great communication. She made our home buying process a breeze. We will definitely come back to her for future real state needs.

Outstanding! Christine first served as a buyers' agent and subsequently as a sellers' agent for us. She was professional in every respect, and we would highly recommend her to family and friends.

Our experience with Christine as our seller's agent could not have been any better. She gave us clear, useful advice during the planning stage and explained everything that we needed to do. She always responded to questions by text, phone, or email right away. Most importantly, she helped us to sell our house quickly, and made the process go as smoothly as possible. Highly recommended!

Christine Mastis is top notch in every category! Her knowledge of real estate and overall professionalism made the process of selling our home easier than we could have ever imagined. She is very accessible and her down to earth personality helped make this a positive experience for all. We would highly recommend Christine if you are looking to buy or sell your home. She will certainly come through for you! We can not thank her enough!

Christine has helped my parents for years and she was referred to me when I was starting my journey of looking for my first home. Christine was very helpful and knowledgeable, she was always available to answer any questions I had regardless of the time of day, she was always at the showings with me, followed through on any task and stayed on top of the Financial institution to make sure deadlines were being met. I would recommend Christine to anyone looking for a top notch Realtor.

I am recommending Christine Mastis as your real estate agent because she sold my house fast and for a great price; because she kept track of all deadlines; because she kept me informed and communicated in a timely manner; because she’s a likable person.

Christine is a true professional who treats each client as an individual. She has years of experience which is valuable in guiding her clients through this stressful process of buying a new home and/or selling their current home. She is very patient, flexible, and quick to respond to questions. She knows when to give advice without overstepping her boundaries. She is aware of and respectful of client’s feelings, viewpoint and goals.

My husband and I are downsizing, selling our home and sending our daughter off to college amongst the new world of covid. We purchased a new “fixer upper” home, sold our home in one day and are on-track with the process....all because of Christine! We couldn’t have done it without her! I highly recommend Christine!

Christine was professional in every aspect of this process. She helped us maneuver a difficult (for us) buyer's market as we "shopped" long distance for our home in Missouri. Christine is very knowledgeable in all areas of real estate and has been supportive before, during and after our closing. We highly recommend Christine Mastis.

Wow! Christine was amazing. Never sold a house so fast! I thought it would take months to sell it because it was an older house that needed lots of live and upgrades to make it feel homey again. Plus trying to sell it during the 2020 pandemic would be more challenging.

Not for Christine. I had the house ready as it could be on a Thursday so she could come take photos for the website. She had the house listed by that Saturday and 2 showing on Sunday. Had a first offer by Sunday night then another offer on Monday.

Christine made the process so easy and smooth. She sent us all the documents to review and sign via email and we closed in just 26 days.

I highly recommend Christine as your realtor. She is not only aggressive, and very knowledgeable, she is there every step of the way 7 days a week.

Thank you Christine.

Christine was wonderful to work with! Not only did she help us sell our condo, but she also helped us find our dream home that checked every box on our list! She is very efficient and on top of everything, so you will always know what is going on during the process! Buying & selling can be stressful, but we are so happy we had her to make it the best experience without the stress! Highly recommend! :)

We have been working with Christine on a referral from a friend since mid July. We put our house on the market at the beginning of August and it had a contract within three days at Full ask price. We then moved into our rental unit in Sunset Hills while she tirelessly walked through home after home with us until finally we closed on our dream home in November 21St. As if that wasn’t enough of us, now she is selling our rental unit in sunset hills. We can’t say enough good words about Christine and her professional acumen, patience and responsiveness. Christine is a great agent to work with and we recommend you get her involved in any and all of your real estate transactions. Thanks again Christine!! If you are still working when we sell this place we will be looking for you!!!

VP of Information Technology
We used Christine when we both moved to St. Louis and again when we sold our house. As both a buyer and seller agent, the execution was solid and without issue. Christine has a great understanding of the market in the area and provides realistic and actionable recommendations on buying a property and selling your property.

Christine enabled us to have a quick sale with minimal work on our part.

Christine was absolutely AMAZING, THOROUGH and PROFESSIONAL! She knows the market and always had the knowledge or knew where to get it. She was always tuned into our needs and provided spot-on recommendations for a fast sell! Nothing was too much trouble and everything was dealt with quickly and efficiently - throughout the entire sales process. She even managed to secure over asking price! Wouldn't trust our real estate needs with anyone else but Christine!
