Yonah Weiss: Why 99% of Investors Don’t Know About Cost Segregation

Welcome to this episode of The Tori Nook Talk Show! In this episode, Tori sits down with Yonah Weiss, the “Cost Segregation King” and Director at Madison Specs, a national cost segregation leader. Yonah has helped clients save over $1 billion in taxes through advanced depreciation strategies—yet when he entered the industry 10 years ago, 99% of the real estate investors he spoke to had never even heard of it.

Yonah didn’t start in real estate or finance. He was a teacher for 15 years—following his mother and grandparents into education. But after a major family health crisis left him struggling with student debt and mounting bills, he pivoted at age 35. He spent two years learning commercial mortgages, discovered cost segregation by accident, and realized he’d found a massive knowledge gap. The most successful investor he knew used it religiously. Everyone else? Clueless.

So Yonah leaned into what he does best: teaching. He started his first 30-day LinkedIn challenge in 2017, launched his podcast Weiss Advice in 2020, and has now been a guest on over 500 podcasts.

They dive into what cost segregation actually is (an IRS-approved way to accelerate depreciation and unlock massive tax deductions), why accountants don’t proactively tell you about it, the Who Not How paradigm shift that changed his business, and his life philosophy: HOPE—Help One Person Every Day.
