Donald J. Trump’s golf club in Jupiter, Florida, where multi-million-dollar villas flank the greens of an 18-hole course, reflects the new geography of his family business. Long based in New York, the Trump Organization has gravitated recently to Florida’s southeast coast, where its golf and resort properties now pay the bills.

A decade ago, before Trump ran for president for the first time as a Republican in 2016, his golf courses and resorts were a drain on the company’s cash flow, which mostly came from real estate, according to a Reuters analysis of court and tax records and other financial disclosures.

But today, the golf and resort business is the biggest driver of the company’s cash flow — accounting for about four-fifths of the approximately $80 million in cash after operating expenses that will be generated this year by the hundreds of companies ultimately owned by Donald Trump, known collectively as the Trump Organization. The group’s annual revenues are over $600 million, according to the Reuters estimate.

The analysis is the first detailed estimate of Trump’s projected 2024 income, as he contests November’s presidential election. It is based on financial statements and other information provided as part of court cases, regulatory filings by Trump Organization entities and their partners, U.S. tax records and other documents.
