About Stephen Portaro

At ERG, clients can anticipate exceptional representation across a diverse range of real estate transactions, from charming condominiums to expansive estates. Clients can be confident that not only their broker but the entire ERG team is dedicated to facilitating a seamless and proficient experience.

In today's real estate landscape, many firms experience high turnover, with agents frequently transitioning between companies such as REX, Redfin, or multi-level marketing platforms like EXP. These environments often prioritize agent recruitment over personalized client service, leaving clients to navigate the complexities of real estate transactions with minimal support. Discount brokerages may offer lower fees, but they frequently compromise on the quality of service.

ERG prides itself on its reliability and commitment to guiding clients through every step of the process, available around the clock. The intricacies of modern transactions demand ongoing negotiation and a keen understanding of market dynamics, making it essential to have experienced professionals by your side. The notion that one can purchase a home online with just a few clicks and save significantly can be misleading.

How does ERG compare to larger real estate firms?

In an era where technology is paramount, ERG leverages advanced tools and resources similar to those employed by larger companies. As a boutique firm, ERG provides the same Multiple Listing Service (MLS) access as its larger counterparts, ensuring equal representation for both buyers and sellers. Additionally, ERG goes beyond traditional MLS capabilities, utilizing innovative marketing strategies that extend to major real estate platforms such as REALTOR.com, Homes.com, Zillow, and Trulia.

While larger firms may offer high-quality marketing materials, boutique firms like ERG excel in tailoring marketing efforts to meet individual client needs. Our focus is on creating customized campaigns rather than relying on generic, one-size-fits-all solutions.

Why choose ERG?

- Extensive expertise across all facets of real estate
- A dedicated boutique team committed to your success
- Utilization of cutting-edge technology
- In-house marketing for bespoke campaigns
- Access to off-market properties
- Continuous client support from initiation to completion
- Strategic and adept negotiation skills
- Stability with a consistent team, avoiding the pitfalls of high turnover
- Assistance with minor repairs, renovations, or staging to enhance property value
- A steadfast commitment to personalized service, accountability, and genuine customer care

At ERG, clients are not just transactions; they are valued partners in a journey toward achieving their real estate goals.
