The Collab

About The

The Collab is led by William Soundias and Jeff Nathanson, two Long Island real estate professionals with 16+ years of combined experience and nearly $100 million in career sales volume. We’ve built our business around local market knowledge, straightforward advice, strong communication, and long-term relationships with our clients. We’re intentionally positioning The Collab toward higher-value seller opportunities, particularly $1M+ single-family homes in Dix Hills, Melville, and surrounding Long Island communities. Long Island remains an extremely competitive seller’s market, driven by historically low inventory. Many homeowners purchased or refinanced at significantly lower interest rates and are reluctant to give up those rates to buy again at today’s higher borrowing costs. At the same time, buyer demand remains strong despite higher rates, creating significant competition for desirable homes when they come to market. Our priority is reaching homeowners who may be considering selling, moving up, downsizing, or relocating, including those who may still be months away from making a decision. We’re looking to create quality seller opportunities and meaningful conversations, not simply generate the highest possible lead volume.
