Tampa Real Estate Guru Dutch Faces Federal Fraud Cases as Investment Empire Unravels

TAMPA, Fla. — Brandon “Dutch” Mendenhall built his public reputation around an appealing promise: ordinary Americans did not need Wall Street to build wealth. Through real estate, alternative investments and financial education, the Tampa Bay entrepreneur presented himself as a guide to financial independence.

Today, Mendenhall and the investment operation he helped build are at the center of a sprawling federal investigation and an SEC lawsuit involving allegations that more than 5,500 investors were deceived in a $152 million investment scheme.

Mendenhall, 46, co-founded RAD Diversified REIT, a real estate investment trust that raised money from investors to acquire residential properties, multifamily buildings, farmland and other real estate. His profile grew through seminars, social media, podcasts and appearances promoting alternative investing. His own website described him as a real estate educator who had helped build a portfolio valued at roughly $250 million.

The image began to unravel as investors complained about delayed payments and difficulties redeeming their investments. In July 2025, Florida Attorney General James Uthmeier announced an investigation into RAD Diversified, Mendenhall and co-founder Amy Vaughn. Uthmeier said his office had received complaints alleging that investor money was being pocketed rather than invested as promised, publicly describing the allegations as appearing to involve a Ponzi scheme.

RAD Diversified ultimately filed for Chapter 11 bankruptcy protection in March 2026.

Mendenhall's problems escalated in May when a federal grand jury in Tampa indicted him on one count of mail fraud. Prosecutors allege that while applying for a $1.2 million mortgage for a $1.6 million residence, Mendenhall inflated his personal income and represented operating accounts belonging to investment funds as personal income because he controlled the businesses. If convicted, he faces a maximum sentence of 20 years in federal prison. Prosecutors have also sought forfeiture of the residence. Mendenhall is presumed innocent of the criminal charge unless proven guilty.

Then came an even broader federal action.

On July 29, the Securities and Exchange Commission sued RAD Diversified, Mendenhall and Vaughn, alleging that from November 2019 through March 2024 they raised at least $152 million while misleading investors about the company's profitability, property valuations and investors' ability to withdraw their money.

The SEC alleges that approximately $54 million in investor funds was transferred to The Seminar Solution LLC, an entity controlled by Mendenhall and Vaughn. Regulators claim the pair ultimately misappropriated nearly $5 million for personal expenses, including private jet travel, luxury goods and recreational spending.

The allegations represent a dramatic reversal for an entrepreneur who marketed financial freedom, authored Money Shackles and positioned himself as an alternative-investment authority.

For Tampa Bay, the case has now become more than the downfall of a high-profile financial personality. It is an unfolding story about thousands of investors, tens of millions of dollars and a once rapidly expanding real estate empire whose finances are now being examined in bankruptcy court, a federal criminal prosecution and one of the SEC's most significant recent fraud cases in the region.
