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 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!!!

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.

Human Resources Manager
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!

We had contacted Christine for the sale of our house as she had sold us the house we had just purchased. Her energy is amazing. She gives great detail to the listing and how she can convey the highlights. She always responded when I had questions. Our house was difficult to sell but with her assistance it is now in the past and we are very happy. We would certainly recommend her to anyone and will use her again if we ever get the energy to move again!

Christine helped us to locate different options for investment property. After finding the one we were interested in, she was excellent through out the process by staying in touch and being a great ‘mediator’ between the seller and us. She always maintains a level attitude and is there to talk out any issues that might arise. We would definitely recommend Christine!

Christine has help us with several real estate transactions over the years. She doesn't just list your home for someone else to sell, she works to sell your home. Christine follows up, follows thru and brings a transaction to closure in timely fashion. Very knowledgeable. I don't know why she doesn't have all the business.

For anyone wanting to sell or buy a home in the Fenton area, I highly recommend Christine Mastis. She worked with me throughout the process- explaining the "whys" and "hows" and supporting me each step as we moved through it. At all times she was professional but yet showed real concern for me as an individual making a huge financial decision. Thank you Christine!

This is the third transaction Christine has assisted me with, and I have recommended her to friends and family since our first. For anyone looking for an agent who is knowledgable, honest, and efficient, there's no question Christine fits that bill. The professionalism she demonstrates is a model for the industry, and it helps facilitate a smooth process from start to finish.

Retired President Bayer Premier Co
Christine Mastis did an excellent job of helping us sell our Fenton house. She provided common sense recommendations on work that helped the sale and maximized the sales price. She had a good list of people that could complete the work timely and for a reasonable price. Her communications throughout the process kept us well informed of the sales status and the next steps in the process. The net result was a contract in six hours and a closing in 26 days after the house went on the market for a sales price $5k over list price. Hard to beat!
