I heard about Kumiko from my Father. He was very pleased with the service she provided and how on top of everything she was for him. I am so glad I took his advice and went with Kumiko.

Kumiko didn't forget a single detail, not even a minor one, during the entire process. She stuck with us over the past 3 months and was responsive at almost all hours of the day. She was quick to learn our needs even as our expectations on the type of home we wanted changed a bit. She is very on top of what is happening in the local real estate market.

This was an exemplary experience. Kumiko made what would otherwise be a tedious and annoying experience an overwhelmingly joyful experience. Kumiko went above and beyond, I will definitely recommend her to anyone moving to the Phoenix area in the future.

Kumiko possesses a calm "can do " attitude that is seldom witnessed today. I would call Kumiko again and again for my real estate needs. Anybody I know of having need of a realtor , I refer them to Kumiko. For me & my husband, there is no other.

Kumiko listened so well during the search, that she remembered things I had mentioned during conversations and she negotiated for details that I was not aware of until after I accepted & signed the paperwork.

Yes, she's all of that!

Kumiko is awesome! She kept this transaction together on so many occasions when it could have fallen apart. She has amazing patience and always has a positive attitude. She can communicate with both sides to keep things moving when there seems like little hope for that. We used her when we purchases our last home in 2018 and have kept in contact over the years. She was the only agent we even considered for both the sale and purchase this year. A great asset to Century 21!!

This has been the most understanding Person I have ever dealt with when it come to realty. Kumiko is awesome and hard to put in few words how my Wife and I feel about her. She has been become one of our family members. There is a special place in our hearts for her. Everybody should be as blessed as we were when my son referred Kumiko.

I personally put her at the top of any realtor. She was the most important person we had for this purchase. She even helped with a great Mortgage company to use.

Just a great experience having Kumiko as our Realtor.

We met Kumiko on our initial visit to maricopa. She was so pleasant and professional and we felt very at ease having her as our agent. Such a patient agent and helpful at every turn.

Top notch in all the above areas. Stayed in constant communication and never made us feel that she was too busy. She would always say " you are my clients", and we truly felt that she cared.

Kumiko lives in the Maricopa area which makes her a subject matter expert. Very much trust her knowledge and experience.

Kumiko is the best realtor we've worked with. She is responsible, knowledgeable, and extremely diligent. She took care of us from the beginning to the end of the purchasing process. She went through all of our documents and advised of important aspects of buying a home. She also worked closely with the builder to make sure that our new home is in excellent condition.

We greatly appreciated having her as our realtor.

Kumiko made the whole process of selling our house easy. She quickly answered all of our questions and kept us updated with the process regularly. I currently reside out of state and that made it hard for me to take care of a lot of things with the house. However Kumiko went above and beyond and helped me coordinate repairs and maintenance. I would highly recommend Kumiko.

Kumiko was available at all times. My work schedule was all over the place and she was very accommodating and answeee all my phone calls and text messages quickly. She even answered questions for me during her vacation. She is very dedicated and listened to all of my concerns and provided excellent feedback/recommendations.

If I were to buy or sell more property in Arizona, I would not hesitate to use Kumiko. I would highly recommend her to all my friends and family in Arizona.

Kumiko did an amazing job with every process of the sale.

Kumiko was the best agent we could have asked for, she is more than attentive and goes way beyond what a typical agent would. Highly recommended. I wish there was a level higher than excellent to give to her. Very knowledgeable of the area which was imperative since we were coming from out of state. She was always accessible and never once did I have to leave a voicemail, she always answers her phone. Best agent we have had in our six prior real estate transactions.

We have recommended her services to our friends and neighbours in Maricopa and in Phoenix. If at the some point we want to buy again, she will be our agent. Kumiko has become our friend and we value hers as well.

Kumiko steered me in what resulted in the correct direction regarding what would impact the sale. After following her suggestions in the second week, interest seemed higher with second viewings by prospects then an offer submitted. Kumiko's recommendations in negotiations were right on the mark. I am very happy & satisfied with Kumiko's performance & professionalism.

Kumiko was very friendly, courteous, and professional throughout the transaction of our home purchase. Since this was a short sale property and we lived out-of-state, it required additional attention in dealing with the long process and attention to a number of unforeseen details.. Kumiko kept us informed throughout the process by giving us detailed weekly updates and following up with personal phone calls.

When the sellers bank finally approved the short sale, the term of the initial property appraisal had practically ran out and we only had some 14 days to prepare the financing papers. This is a process that normally takes some 45 days to complete. Through Kumiko's contacts and personal initiative, she was able to put us in contact with a local mortgage broker that was supportive in helping us gather all the necessary documents prepared in time to meet the deadline.

We will always remain thankful to Kumiko for her hard work, commitment, and diligence in making this purchase a reality. She was and is the ultimate professional. She earned our respect and highest recommendation.
