Working with Sean was a pleasure from start to finish.

I specifically used Sean as he reached out to me with a post card about your agency. I'd had my unit on sale for over 2 yrs with no responses. Sean went in my unit took great photos and we went from there. He handled all of the issues big and small As I was an out of state owner it was greatly appreciated. I've already referred him to my neighbors who are considering selling their units. Bravo Sean... Thank you again for your tenacity.

Working with Sean Hegarty to sell our house in Jupiter was the BEST decision we ever made!

Sean was extremely knowledgeable and totally trustworthy! He treated the sale of our house as if he was selling his house and managed every step in the process with complete professionalism, integrity, and diligence. He routinely went above and beyond the call of duty in prepping our house for sale and exposing it to the right pool of prospective buyers! In summary, Sean was truly exceptional and we would recommend him to anyone without hesitation. He was outstanding!

Exemplary Service

Working with Sean to sell my home was an exceptional experience from start to finish. From the initial listing through closing, he demonstrated a level of professionalism, market knowledge, and attentiveness that truly set him apart. One aspect that stood out in particular was Sean’s commitment to being present for every showing. That level of involvement is something not all agents prioritize, yet it made a meaningful difference. His presence ensured that prospective buyers received thoughtful insight about the property and that every showing was handled with care and intention. Just as important as an agent’s knowledge of the market is their ability to align with a seller’s expectations and strategy. Sean understood that balance perfectly. He took the time to listen, communicate clearly, and guide the process in a way that respected both the property and the goals we had for the sale. Overall, it was a seamless and highly professional experience. I would confidently recommend Sean to anyone looking for an agent who is engaged, knowledgeable, and fully invested in delivering results.

Sean Hegarty's market knowledge, communication, and professional well exceeded expectations.

We couldn’t have asked for a better realtor to guide us through purchasing our first home! From day one, Sean Hegarty went above and beyond to make the entire process smooth, stress-free, and even enjoyable. He was incredibly friendly, approachable, and always made us feel truly heard and supported throughout every step. What stood out most was how well he listened to our needs and preferences. We never felt rushed or pressured—just consistently accommodated and understood. His deep knowledge of the market was clear, and he used it to help us make smart, informed decisions with confidence. Communication was flawless. He was always quick to respond, transparent, and proactive about keeping us updated. Whether it was setting up showings, explaining next steps, or answering our many first-time-homebuyer questions, he was there with patience and professionalism every time. We’re incredibly thankful for Sean Hegarty’s unwavering support and commitment throughout our home-buying journey. Because of his knowledge, hard work, and guidance, we’re now settling into a home we truly love. If you’re searching for a realtor who is knowledgeable, genuinely cares, and goes above and beyond for his clients, Sean is the one—we wholeheartedly recommend him to anyone!

Denice is Terrific!

Denice and her team of professionals helped me ready, list and sell my parents beachfront condominium. Their understanding of SE Florida properties and the appropriate selling strategy were excellent. Her accessibility and communications were also top notch. I highly recommend Denice and her team.
