From $80K in debt to a repeatable wealth system
Seven years between the debt in 2017 and the $15M+ portfolio today.
I'm Preston Seo. My parents were first-generation immigrants, so nothing arrived by default. After college I took a corporate job and left within a year, then started studying money from every angle: taxes, cash flow, investing, ownership.
What actually changed
Real estate and Airbnb were part of the breakthrough, but not the whole answer. The bigger shift was learning how taxes, ownership, cash flow, and decision-making fit together.
My wife and I built a $15M+ real estate portfolio on the back of that. The portfolio is the result. The system is the thing worth copying.
That is what Legacy Investing Show teaches. Not one tactic, but the system underneath it.
What happened, year by year
The debt was $80,000 in 2017 and paid off by 2019.
-
2017
The starting point
$80,000 in debt while employed full time, with no system for taxes, cash flow, or investing.
-
2018
First experiments
Income, ownership structures, tax moves, real estate. Some worked. Others were expensive lessons.
-
2019
Debt cleared
The $80K was paid off.
-
2020
Legacy Investing Show
Founded to teach the frameworks rather than the tactics.
-
2024
Past 2,000 students
Guided through the same frameworks, one decision at a time.
What I actually teach
Four areas carry most of the work, with two more supporting them.
- Tax strategy
- Which deductions, structures, and timing decisions apply to your situation, and in what order.
- Investment planning
- How to choose between assets on the numbers rather than on the story attached to them.
- Business structures
- Entity choice, ownership, and how the structure changes what you owe.
- Retirement accounts
- Solo 401(k)s, IRAs, conversions, and the trade-offs between them.
- Debt management
- Paying down debt as one option among several, compared against investing the same dollar.
- Alternative income
- Airbnb arbitrage and other income streams that do not depend on a salary.
Airbnb arbitrage is about 20% of what we do, and it is the part people know me for. The other 80% is tax strategy, investment planning, structures, and retirement. That is where most of the money actually moves.
Who this is for
Students typically earn $75K+ and fall into one of four groups.
- High earners paying more tax than they expected to
- Business owners deciding how to structure and pay themselves
- Real estate investors sizing up depreciation, exchanges, and entity choices
- Professionals building a first wealth system from scratch
