I specialize in helping seniors and their families navigate major transitions with clarity, compassion, and confidence. Whether you're downsizing, relocating, or planning ahead, I offer guidance tailored to your unique needs. As someone who deeply understands the emotional and logistical challenges associated with the sale of a family home, I recognize that real estate is not just about transactions—it's about people, memories, and making thoughtful moves for the future.

Excellent Communicator

Allison was great to work with. She was responsive and communicated often. She went above and beyond supporting us when we had showings on our house.

Freindly professionalism

Freindly professionalism

Selling a home, particularly a home one has lived in for over 35 years, as in our case, is a daunting task. Fortunately, we had Allison Costelow to advise us and handle the complex organization of inspections, prep work, listing and the final showing, all at own pace. It was certainly a learning experience, yet Allison was always available to answer our questions. Preparing our home and the surprisingly rapid sale would not have been possible without her professional, experienced and friendly guidance.

100% Satisfaction guaranteed!!!

Selling a home is a MAJOR life moment, one WE were not ready for at all.... ENTER CLAUDIA LOPEZ and ALLISON COSTELOW (REMAX Benicia). a DREAM TEAM for sure. I greatly appreciate how professional and knowledgeable Claudia and Allison are and how they patiently explained to us each step in the process, our job was to trust the process...as they handled everything from coordinating inspections, appraisals, pricing the home, listing the home, coordinating open houses ... private showings TO receiving an offer and to ultimately selling our home. Claudia’s and Allison’s DEEP knowledge of the real-estate market and their marketing strategies proved to be invaluable and made us feel confident and informed at every turn. There was a day ... early on in the process, a dark day for me personally, when I was doubtful we would sell, well I needed a pep talk and I got one From Allsion...her pep talk was amazing and what I needed to stay the course, trust the process and trust these two amazing REALTORS...ALLISONS WORDS TO ME ... “I KNOW IT LOOKS LIKE A LOT, BUT WE HAVE DONE THIS AND CAN HANDLE THIS” ... she was right on both counts. AGAIN .. TRUST THE PROCESS and I did from that day forward with greater confidence and within 3 weeks we had a competitive offer, accepted the offer, (even had a backup offer) and the house closed in 21 days. Here’s to new beginnings. From my 1st call to CLAUDIA and ALLISON, to their last call to me congratulating me on the sale of our house I felt so understood, supported, guided and expertly taken care of. The process was so smooth and hassle free I cannot recommend CLAUDIA and ALLISON enough! If you are looking for REALTORS LOOK NO FURTHER! CLUADIA and ALLISON are good people and do good work!

Great Realtor

Great Realtor

Allison Costello was my Realtor when I purchased my Manufactured Home in Benicia CA. She was very helpful in not only the purchase but other needs I had. I also have a home in Fairfield that I needed to remodel and sell. Allison was great in helping me find local service providers. Allison will provide you with great services. Sandra Jones Benicia CA

She's the best!

She's the best!

I was very happy with everything that Allison did from the moment I met her up until now weeks after the purchase of my first home. She had to deal with myself and my 75-year-old mother and she was able to make both of us happy at the same time which usually is pretty hard to do. She was very informative she knew pretty much everything that you would need to know about a home and what she didn't know she knew who would know the answer to any question I had. I put my trust in her hands and she works so hard for me I can't even begin to express my gratitude and satisfaction I will forever use Allison as a realtor and recommend her to all my family and friends forever and ever. I promise you that no one will ever work harder than that woman does. She is a family woman and a business woman all wrapped up in one tremendous awesome spunky ball she has the humor when you need it and she is serious when it needs to get serious. You cannot go wrong with Allison.
