What does it really take to build a successful real estate career in one of the most competitive markets in the world? Before appearing on Netflix’s Owning Manhattan, Nile Lundgren was making hundreds of cold calls, struggling financially, and building relationships that wouldn’t pay off for years. Today, he’s part of Ryan Serhant’s real estate brokerage, proving that long-term success in real estate isn’t built on quick commissions. It’s built on relationships, market expertise, consistency, and systems.

In this episode, Aviva Sonenreich and Nile Lundgren, a New York City real estate broker and star of Netflix’s Owning Manhattan, discuss what it takes to build a successful real estate career, attract high-value clients, and grow a sustainable real estate business in a highly competitive market.

Nile shares his journey from renting inexpensive apartments in New York City to becoming a founding agent at SERHANT., the brokerage founded by Ryan Serhant. He explains how strategic networking, authentic client relationships, and years of persistence helped him develop a successful book of business long before his television exposure.

Aviva and Nile also explore the realities of New York City real estate, including why co-ops operate differently from condos, why off-market properties aren’t always the best investment opportunities, and how experienced brokers help clients avoid costly mistakes.

Beyond closing deals, they discuss the importance of becoming an expert in your local real estate market, using social media to build credibility, and creating repeatable business systems that allow a brokerage team to scale.

Whether you’re a new real estate agent, an experienced commercial real estate broker, an investor, or someone looking to build a lasting career in the industry, this conversation offers practical lessons on real estate lead generation, client acquisition, networking, brokerage growth, and long-term success.
