Great communication, negotiation and always prepared

Great communication, negotiation and always prepared

Working with Allison was an exceptional experience from start to finish. She was incredibly communicative, prepared, responsive, and always made us feel like we were in good hands throughout the entire process of selling our home. What impressed us most was her negotiation skills. Whenever she came to us with an offer or a request, she didn’t just present it to us—she was thoughtful about how she could negotiate something in return that would make the process easier for us while still making the deal more enticing for the buyer. She consistently looked out for our best interests and helped us get what we wanted while keeping the process as smooth and stress-free as possible. Allison was professional, knowledgeable, and genuinely so easy to work with. We always felt like she had our back, and we trusted her to navigate the details and negotiations along the way. We would absolutely recommend Allison to anyone looking to buy or sell a home. She is a fantastic Realtor and we are so grateful for all of her help!

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.
