On this episode of Zen and the Art of Real Estate Investing, Jonathan Greene shares a solo episode challenging one of the most common habits in modern real estate investing: relying too heavily on spreadsheets to make decisions. Despite openly admitting that he loves spreadsheets and uses them extensively across his businesses and daily life, Jonathan explains why investors can get themselves into trouble when spreadsheets stop being tools and start becoming substitutes for judgment, experience, and real-world investing skills.

Jonathan breaks down how spreadsheets can create a false sense of certainty by allowing investors to manipulate assumptions until a deal appears to work. From adjusting vacancy rates and repair budgets to stretching future projections and return expectations, he explains how easy it becomes to convince yourself that a deal is better — or worse — than reality. Rather than treating spreadsheets as predictive machines, Jonathan encourages investors to view them as rough frameworks that must be validated through due diligence, property visits, market knowledge, and practical experience.

The episode also explores the limitations of spreadsheets when evaluating the parts of investing that can't easily be measured. Jonathan discusses why factors like geography, neighborhood quality, tenant selection, management ability, deferred maintenance, traffic patterns, layout issues, and even intuition often matter more than perfectly modeled returns. He explains why many investors become trapped in what they call "analysis paralysis," when in reality they may simply lack enough real-world reps and confidence to make decisions.

Throughout the episode, Jonathan emphasizes that successful investing requires balancing data with action. He shares why experience sharpens judgment over time and why some of the most important investing decisions happen outside of formulas and projections. Ultimately, this episode serves as a reminder that spreadsheets should support decision-making — not replace observation, instinct, and the ability to adapt when reality inevitably differs from the model.

In this episode, you will hear:

• Why spreadsheets should be used as tools rather than substitutes for investing judgment
• How changing assumptions can make almost any deal appear to work on paper
• Why viewing properties and validating assumptions matters more than projections
• The investing risks spreadsheets cannot account for, including people, geography, and operations
• How overreliance on spreadsheets contributes to analysis paralysis and slows decision-making
