This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Investors move fast. Most agents don’t.** If you can’t evaluate a deal quickly and confidently, you lose credibility—and the opportunity disappears. Deal or Disaster teaches a simple, repeatable framework to determine in minutes whether a deal prints money or burns it. In this session, you’ll learn a 5-minute investment evaluation system that works across flips, rentals, BRRRRs, wholetails, and creative deals. The goal isn’t perfection—it’s speed, clarity, and credibility. We’ll break down: * How to identify the investor’s true goal before running numbers * A fast, reliable method to estimate ARV with confidence * How to calculate the real all-in acquisition cost * Simple heuristics to ballpark rehab and improvement costs * The key metrics that reveal whether a deal works—or should be killed You’ll also learn the most common red flags that signal bad deals, thin margins, and hidden risk, so you know when to pause or walk away. When you can analyze deals in minutes, you earn authority, build trust, and become indispensable to investors. Speed creates opportunity—and opportunity creates repeat business. If you want to move from real estate generalist to trusted investment strategist, this session gives you the framework to do it. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The Hidden Cleopatra,”** an excavation through myth and slander to uncover the real Egyptian queen, with Jacquelyn Williamson, an Egyptologist and associate professor of archaeology and ancient art at George Mason University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/hidden-cleopatra](https://www.ticketleap.events/tickets/profsandpints/hidden-cleopatra) .] Depictions of Cleopatra are abundant in popular culture. A long list of painters have depicted her, Marilyn Monroe and Kim Kardashian have posed as her, and Vivien Leigh and Elizabeth Taylor famously portrayed her in Hollywood films. At the end of the day, however, what most of us think we know about Cleopatra is wrong, the product of the ancient Rome’s “fake news” and anti-Egypt propaganda. Learn about the real Cleopatra—and how our understanding of her came to be so distorted—with Professor Jacquelyn Williamson, scholar of women and power in ancient Egypt, teacher of courses on ancient Egyptian art and archaeology, and author of *Nefertiti’s Sun Temple: A New Cult Complex at Tell el-Amarna.* Dr. Williamson will walk us through how the first Roman emperor, Octavian, created the distorted image of Cleopatra as seductress that we know today as part of his political scheming to defeat his rival Antony and end the Roman Republic once and for all. Cleopatra has been the subject of debate and controversy ever since. William Shakespeare later relied on ancient Roman sources such as Horace and Plutarch in writing *Antony and Cleopatra*, and his play helped give rise to countless other works offering a distorted picture of her. Professor Williamson argues that “Cleopatra was a human being, like you and I,” and “deserves the dignity of being represented as accurately as possible.” Her efforts to set the record straight have met frustration, however—after being extensively interviewed for the recent Netflix historical docuseries Queen Cleopatra, she concluded that it, too, had missed the mark. You’ll gain a much deeper appreciation of the challenges of researching and accurately depicting the ancient past from Dr. Williamson, who also has taught at Harvard, Brandeis, and the University of California at Berkeley and is involved with an ongoing archaeological investigation of Queen Nefertiti’s sun temple.
