It is extremely important to find a great realtor when you embark on the home buying journey. It is a huge transaction that requires your realtor to have expertise, patience, organization, and effective and prompt communication in order to be a successful and smooth process. Antoinette is all of those as well as responsive, kind, and an advocate for her buyers. You will be in good hands with Antoinette. She helped us secure our dream home and we are truly thankful. I'll be sure to let anyone I know looking for a home to reach out to Antoinette.

Antoinette attention to detail, personal attention, communication skills, experience and dedication was excellent. She was friendly, considerate and punctual to showings. She created a trusting partnership that helped us to find our forever home. Without her, our buying experience would have not been the same. Antoinette made this home buying experience a win! We purchased a home that went above and beyond our expectations. We owe that to Antoinette for finding and researching properties that accommodated our needs. Well done Antoinette!

Antoinette was amazing start to finish. She was patient and personable and always made sure she was available and that our questions were answered and our needs were met. During this crazy house buying time she was exactly the agent we needed by our side. I sing her praises to anyone I talk to that is buying or selling a home. 20/10 HIGHLY recommend.

My overall sales experience with Antoinette has been incredible, and I am delighted with her. She always returns my phone calls if she doesn't answer right away, and above all, she made sure that every part of my home-buying process was as painless and stress-free as possible! Antoinette was always available to answer my questions and had my back from start to finish. I couldn’t be more pleased with my experience!

We loved working with Antoinette! We were matched through Realtor.com, but she was the perfect fit for us. She was responsive and patient with us. No pressure, but always available to answer our questions and encourage us through the whole process. We would recommended Antoinette to anyone looking for a new home.

Antoinette Porter is the absolute best at what she does. I was referred to her by another agent and I couldn't have found better. On our first phone call, I told her my family must haves. She EXECUTED every request! Being a first time home buyer, I was so nervous and of course a little anxious on this journey. She guided me every step of the way. She is very knowledgeable, personable and most importantly available. She has earned a client for life and I will definitely refer her to all of my friends and family.

I'm so glad Mike referred Antoinette to me at the beginning of my home buying process. She is very friendly and had a approachable and welcoming attitude from the start. I felt like I was in good hands, especially with this being my first time. Whenever I had a question Antoinette was quick to respond with the information I needed. She assured me I could never ask too many questions or be a bother to her. We definitely built a great rapport with each other. I couldn't ask for a better real estate agent. I look forward to working with her again in the future and I will definitely recommend her to my family and friends.

There are so many things that can say about her professionalism and her character as an agent. Antoinette Porter exceeded the standard of what I expected. When I wanted to throw in the towel she was there to encourage me to not give up. Her being able to work well with others and communicate well, I will refer her to not just other potential clients, but to more Veterans. She did an awesome job, and I am enjoying my home.

When I first sent out an email looking for an agent, I started with 2 different agencies. Antionette Porter was the first to respond.

Listed the house and immediately Antoinette scheduled an open house. We had 2 firm offers on the very first day it was on the market.

Any time we had a question Antionette responded every time within 30 minutes if not less. Very accessible and understanding of what we were looking for.

I have already recommended Antionette to another neighbor on the street. They are thinking of listing in the spring.

Jackie Malone
Maryville, IL - Jun 30, 2021

Looking for a home is somewhat stressful. The market was unbelievable. I almost gave up and decided to maybe look in about another year. Antionette would always say “ Ms. Jackie we are going to find you the perfect home….. and she did! I’m very pleased with her level of professionalism. I’m already looking for my next property to purchase. She has a lot of patience and I’m looking forward to working with her again!!!
Antionette was very patient, considerate, kind and understanding! Was always willing lend a helping hand!

Antionette came with a wealth of knowledge! If she didn’t know an answer she would quickly outreach her broker.

I enjoyed Antionette from start to finish!
