I cannot say enough wonderful things about Sonja Coffee and the support she provided during one of the most challenging times in my life. Selling the home of a loved one who has transitioned into memory care is an emotional and overwhelming process, but Sonja handled everything with incredible compassion, kindness, and professionalism. From the very beginning, she took the time to truly understand my goals—selling the home quickly while also securing the best possible price to help cover my loved one's ongoing memory care expenses. She kept me informed every step of the way, always communicating clearly and making sure I felt confident in every decision. What stood out most was how much she genuinely cared. Sonja lifted an enormous amount of pressure and stress off my shoulders, allowing me to focus on my family during such an important time. Her knowledge of the market, attention to detail, and steady guidance made all the difference. I truly can't imagine where I would be in this journey without her by my side. I am beyond grateful and would wholeheartedly recommend Sonja to anyone in need of a knowledgeable, compassionate, and dedicated real estate professional.

Memory Care Home Sale
We highly recommend Sonja Coffee for any one that is looking to purchase a new home. When we first started our search for our home we had a different realtor. For the first four months we couldn't get our offer to get accepted even when offering above market value. Then finally we decided to switch realtors, one of my good friends gave us Sonja's information. My fiancé got a hold of her, we told her about our four month search and tactics we had been using with the previous realtor just to get our offer looked at. That day she told us to select the houses we were considering so that she could set up appointments to look at them. Within a couple of days she set up the showings. For every house we went to she would gives information about the property, community, and re-sale value. That information is perfect specially for a guy that is not from California and has no knowledge of the properties here. When we decided on a home and it came time to writing the offer, Sonja took the initiative to write a letter to the sellers about us. Something that I had never heard of, only thing I heard from the other realtor was "we have to offer more money" :D. Within less than a week she was able to get our offer accepted, not only was it accepted but it was with a VA loan (which are kind of difficult to work with when selling a house due to regulations). The process went smooth after that and she worked with my schedule specially with me working very late. This is why I would highly recommend Sonja Coffee to any one, specially any veterans out there having a hard time getting their offer accepted with the VA loan.

Five star experience working with Sonja Coffee on the sale of my house! Her friendly guidance and strong market experience every step of the way was invaluable to my family. She welcomed questions about the process and always offered clear and helpful explanations and was always just a phone call or a text away. Our house was sold much faster and for top $ in a changing market - all due to her years of experience. I will be a returning client!

We are first time home buyers, new to the whole process. Sonja was very helpful and professional/supportive in every aspect along the way. She was able to expedite our wants and needs during this crazy time. Providing masks/gloves and doing whatever necessary for us during this trying time to close on our beautiful home. If you are looking for a friendly/professional realtor with the experience to get things done, Sonja should be your first choice. We are so grateful and enjoyed all our experiences working with Sonja Coffee. Highly recommend.

We highly recommend Sonja for your real estate needs. We are a repeat client as our 1st experience of selling a property was A+++. This time she helped us purchase our new home. Again was very professional. She kept us in the loop of all communications with the seller's agent. Her recommendation of the home inspection company was so helpful too. She truly looks out for any and all of her client's needs. She definitely goes above and beyond, which is hard to find these days. Thanks Sonja!! You're the best!
