William James

Real estate isn't a side hustle for me. It's legacy.
I was raised around this business. I've seen what great service looks like and I've seen what happens when agents treat it like a transaction instead of a responsibility. That shaped everything about how I work.
As a REALTOR® with Signature Premier Properties, I combine deep local knowledge of Nassau and Suffolk County with real strategy data, sharp negotiation, and systems that give my clients a genuine edge. Whether you're buying your first home, upgrading, downsizing, or building wealth through real estate, I'm focused on one thing: positioning you to win.
I've closed over $31.9 million across Long Island, and I approach every client the same way. With honesty. With hustle. And with the understanding that this decision matters long after closing day.
I'm a girl dad, a community advocate, and someone who believes real estate is one of the most powerful wealth-building tools available. My goal isn't just to help you move. It's to help you move forward.
I'm William James but my clients call me Billy. If you're looking for someone who treats your goals like his own, let's talk.
