NEW DEVELOPMENT

Bringing a new development to market requires a strategic, data-driven approach and a team with the experience to execute at the highest level. As a full-service real estate team, we partner with developers from the earliest stages of the project - offering expert advisory throughout the pre-approval process, crafting compelling marketing strategies, and driving sales from launch to sellout. With in-house marketing, graphic design, and web development, we ensure every project is positioned for maximum exposure and success.


Our proven track record speaks for itself. We understand how to shape a development’s identity, target the right buyers, and create demand in competitive markets. At the center of our new development success is TJ Verdiglione, whose deep industry relationships and market expertise make him a trusted partner for top developers.


Beyond strategy and relationships, we’ve built a proprietary 200+ task project management system that ensures we stay ahead of every challenge new development can present. From marketing strategies and asset generation to sales tracking and inventory management, our system keeps every detail on track, allowing us to anticipate and solve issues before they arise. This level of structure and foresight ensures a seamless process for developers and maximizes the success of every project we bring to market.


From concept to closing, our team provides the expertise, marketing power, and sales execution that developers need to achieve outstanding results. We don’t just sell properties - we build legacies.
