Story behind rea (REA) co-founders Adam Eatros and Mark Kappelman (CPA, CFA) have always shared a passion for real estate, technology, and clean financial data. Individually, they have founded and scaled venture-backed technology companies, worked in public accounting at PwC and Ernst & Young, and personally acquired millions of dollars worth of real estate as both GP’s and LP’s. Together, they look to leverage intelligent human interaction with automation technology to help solve the financial frustrations they know all too well that come with growing and managing a portfolio of properties.
At REA, we understand that most real estate companies do not have the need or resources for a full-time controller or accounting team. That’s where we come in. REA was built from the ground-up with both the real estate investor and property manager in mind to take care of the financial administration associated with running a successful real estate business. You can think of us as your in-house accounting team, just at a fraction of the cost and response time versus most other DIY solutions.
What differentiates REA from other accounting & bookkeeping firms is that we specialize in real estate and property management. This means we only work with real estate companies – providing us with unique knowledge, experience, and skills that we leverage to help our clients manage and ultimately scale their businesses. With real estate being our expertise, you can sleep better knowing your financials are setup correctly and accurately completed on a monthly basis to maximize profits, improve financial insights, and keep you in accordance with Trust accounting laws.
It is our vision at REA to build a company committed to helping our clients take their businesses to places they never thought were possible. We look forward to partnering with you on the journey!
