Data-Driven + Experienced

Our emphasis on data sets our Team apart, with the goal of arming our clients with the most accurate information available to help them make the best decisions for their real estate portfolio.
For our buyers, we don't think of our role as a friend simply walking them through properties, but rather as an advisor pointing out often intangible factors that affect a property's value and using this to frame our negotiating strategy.  
For our sellers, we provide comprehensive valuation reports, but even more importantly, our extensive experience in working with buyers allows us to put these valuation reports into real-time perspective and create an optimal pricing and marketing strategy for each property.
Whether it is a buyer's market or seller's market, we've seen it all, and we understand that there is no single "market" in NYC; each neighborhood and property type requires a nuanced approach. Our comprehensive monthly or quarterly real estate reports track what's going on in the NYC market in relevant terms and are created internally by our Team based on our analysis of the raw data and what we observe each day in our own transactions.
