REMAX AT BARNEGAT BAY - SHIP BOTTOM

Real estate is more than a business to us — it is a passion built on experience, knowledge, and a genuine love for the coastal lifestyle.

As a mother-daughter team and experienced Brokers with RE/MAX At Barnegat Bay, we have proudly served Long Beach Island and its surrounding communities since 1994. With decades of experience and an extensive understanding of the LBI real estate market, we specialize in representing buyers and sellers of exceptional coastal properties, including multi-million-dollar luxury homes, second homes, and investment properties.

Our experience extends beyond the Jersey Shore. Having worked on Sanibel Island, Florida, in the timeshare market, we bring an additional perspective and understanding of resort, vacation, and second-home ownership.

We offer valuable expertise in 1031 tax-deferred exchanges, investment opportunities, rental income potential, and the unique considerations involved in purchasing and selling vacation and second-home properties. Whether navigating the luxury market, identifying an investment opportunity, or helping clients find their perfect island retreat, we provide knowledgeable guidance and personalized service throughout every step of the transaction.

Our business is built on lasting relationships, professional integrity, strong negotiation skills, and an unwavering commitment to our clients. We take pride in combining generations of perspective with decades of market experience to deliver exceptional results.

Whether buying, selling, or investing, let our experience, local knowledge, and passion for coastal real estate work for you.

What our clients say

It was our pleasure to work with you. We appreciate your diligent advertising of our condo - the pictures and videos were so well done. We are very happy the condo was sold to a very nice young man and his mom. We are certain they will enjoy it and make good friends, as we did

— Kim & Tom

What our clients say

It has been a particular pleasure and bonus for me to have "worked" with such a lovely and gracious lady. I will miss our regular conversations that I have become happily accustomed to over the last several weeks. When we decided to sell our beloved home, we pondered whether to place it with a realtor or to try to sell it on our own. You proved without question that we made the right decision. After we get settled into our new "digs", I hope that you and your husband will accept an invitation to visit us. In any event, I wish you continued success and, most importantly, good health. May the future provide you and your family the best that God has to offer.

Thank you for all the detailed market analysis for my mom's property. With your help, I was able to provide everything the attorney needed. Hope you and your family are well. I'm sure you are as busy as ever. You are truly a special person and a fantastic realtor. You found my house for me, and I have always been happy with this decision. I remember you showing us so many houses! Nothing felt right until we saw our home. I thank you for that as always. I hope to see you again sometime. If my mom decides to sell, you will be the first one I call!. Take Care!
