Private equity is used to fund most of our property purchases and it is our aim to continuously provide secure investments with strong cash flow and appreciation. Today’s high-stakes real estate environment provides significant opportunities that are not necessarily readily recognizable and that may be transient, making it essential to work with a firm that recognizes opportunities and exploits them before they disappear.

Portfolio Criteria

Portfolio Criteria


Rok seeks to build a diversified assortment of properties and assets in strategic locations across the United States. The company invests in properties that generate income and yield appropriate risk-adjusted returns with correspondingly low volatility, adequate liquidity, and low correlation to broad market indices.

We are guided by a disciplined investment philosophy and process. Our goal is to source, evaluate, and invest in select income-generating multifamily and commercial real estate properties that are overlooked by less experienced and less opportunistic investors, or that are too large and complex for investors with insufficient resources and infrastructure. We are also engaged in ground-up development, including a residential apartment complex in Boca Raton, as well as the redevelopment of distressed properties or select historic landmark properties.

We utilize advanced risk management techniques and portfolio modeling capabilities to professionally underwrite its acquisitions. We make investments that capitalize on market inefficiencies by opportunistically acquiring undervalued property and/or distressed loans; we seek to maximize recoveries by utilizing long-standing banking, institutional, and governmental relationships. Capital preservation and risk management are the primary objectives of the management team. We are vertically integrated and have the extensive resources and infrastructure required to source, analyze, value, purchase, service, manage and dispose of real estate properties and assets, or retain acquisitions when warranted.

We provide the potential for value-added returns based on strong, disciplined real estate management, leasing, and marketing. Our team has unsurpassed expertise in creating and implementing a management approach that will successfully invigorate the income streams and value of individual portfolio investments. The management plan is designed prior to completion of an acquisition so that it can be immediately executed upon closing. Depending on the location and property type, management may be delegated to a third-party, handled directly, or kept in place through an arrangement with the existing staff. Due to the critical nature of management in achieving value-added returns, we maintain tight supervision over every aspect of property management and operations.

Investment Approach

Investment Approach


We conduct rigorous quantitative, statistical, and qualitative analyses of possible investments utilizing customized models and systems. The few properties and/or assets that survive the initial process are targeted for further, more precise investigation. The ultimate goal of the process is to provide a portfolio of superior properties and/or assets which is diversified across property types and class, and geographic market. We follow a logical path to ensure sound investments, including sourcing, property review, core due diligence, investment approval, and post-investment refinements and updates.


We utilize strong, industry-wide relationships with local, regional, and national lenders, institutional providers, and governmental agencies.

We also call upon a vast, nationwide network of brokerage and advisory relationships, as well as research databases, proprietary industry lists, industry journals, and public records.

Property Review

Prior to an acquisition, potential investments undergo an initial review process, which may include property visits, market and comparable property analyses, historic performance review, and loan re-underwriting assessments.

The review phase is used to develop a deep understanding of the real estate and/or loans, as well as all pertinent legal documentation.

Core Due Diligence

Once we have determined that a potential investment meets our acquisitions criteria, we then subject it to rigorous core due diligence. Our broad experience in the real estate sector enables us to rapidly accomplish the necessary steps involved in core due diligence and thereby allows us to close quickly on the most complex transactions.

Our core due diligence process generally includes:

  1. Review of the property and/or asset data, including financial, local, legal, and market information
  2. Stress testing and scenario analyses appropriate for risk management
  3. Title searches and documentation
  4. Third-party valuations
  5. Property inspections, including detailed physical, environmental, and engineering reports as needed
  6. Reviews of the local economy and demographics, neighborhood economics and trends, qualitative and quantitative analyses of market competition, area rates, vacancies and market position.

Post-Investment Review

Following acquisition, investments are subject to monthly surveillance and reports with an on-going comparison of results to objectives and updating of the portfolio correlation analysis and the market/comparables analysis. A continuous post-investment review process monitors risk and adherence to risk limits and guidelines. Value enhancements are considered and reviewed throughout ownership. Exit scenarios are also monitored. On-going review enables us to respond as needed to market and financial realities and opportunities to enhance and maximize returns.

Investment Approval

An acquisition requires team review and approval,  which is conducted according to a formal investment committee process. A majority approval of the acquisition team is required in order to invest in any real estate or real estate-related asset.

Our History

Our History


Beginning with Natan Rok, the Rok name has become synonymous with the emergence of Miami, Florida into a world-class center of commerce and the arts.

An emigrant from Cuba, Natan Rok arrived in Miami in 1964 and opened a modest retail business on historic Flagler Street. He and his son, Sergio, who joined the business in 1983, envisioned the area’s future as a true hub of cultural and commercial vibrancy. 

Together they parlayed the business into a real estate empire centered on the core of the city.The Rok organization set the trend for modernization while maintaining a property’s unique character and historical charm. They also pioneered the practice of subdividing commercial properties into small retail spaces, despite predictions the idea would fail.

Along with their real estate activities, the Rok organization purchased a controlling interest in Transatlantic Bank and spent the better part of the 1990s growing the bank’s business. In 2004, Sergio Rok succeeded his father as head of Rok Enterprises and spearheaded the continued growth and eventual sale of Transatlantic Bank to one of the largest banks in Spain.

Mr. Rok has built his own reputation for real estate prowess and business acumen. In the footsteps of his father, he has continued to make significant investments and build the Rok portfolio of properties. Considered a heavy hitter among commercial real estate property owners, Mr. Rok has been integral to some of the city’s biggest deals, blending a rare talent for negotiation with keen insight into the hands-on mechanics of the retail and financial services sectors.

In 2009, Rok Acquisitions, LLC was formed to leverage the Rok organization platform and resources to pursue new real estate and real estate- related opportunities. Rok Acquisitions, LLC has been involved in some of the largest real estate-related transactions in the Southeast.
