Josette Chang and Alexander Nathanson, a financially independent couple in New York City, have retired in their 40s by making strategic decisions around their investments, lifestyle, and long-term plans. The couple paid off their mortgage early, live off Nathanson's part-time income, and have a simplified investment portfolio focused on low-cost index funds. They also chose not to have children and embrace a 'die with zero' mindset, prioritizing experiences over building a large estate. Avoiding lifestyle creep and comparison has been central to their path to early retirement.

Why it matters

The story of Chang and Nathanson's path to financial independence at a young age provides an inspiring example of how intentional choices around spending, investing, and lifestyle can enable early retirement, even in an expensive city like New York. Their approach challenges common assumptions about the barriers to achieving work optionality and highlights strategies that could be replicated by others seeking similar goals.

The details

After getting married in 2018, Chang and Nathanson bought an apartment in Midtown East, transitioning from pricey NYC rent to a mortgage payment. They paid off their mortgage entirely by 2024, drastically reducing their housing costs. That same year, Chang quit her finance job to begin early retirement, while Nathanson scaled back his hospital hours as a physician. The couple now comfortably lives off Nathanson's part-time income, without needing to draw from their investment portfolio. Their investment strategy is intentionally simple, consisting of just three low-cost index funds. They've also deliberately avoided more speculative investments like individual stocks and cryptocurrency. The decision not to have children has been central to their financial plan, as they don't need to save for a large estate to pass down. Instead, they embrace a 'die with zero' mindset, prioritizing experiences over endless portfolio growth.
