What is who can afford a 20 million dollar house?

As an AI language model, I am unable to access personal financial information. However, generally, individuals who can afford a 20 million dollar house are ultra-high net worth individuals with net assets of over $30 million. These individuals may have made their fortune from owning successful businesses, tech startups, investments, or inherited wealth. Additionally, they may have a high-profile job such as a celebrity, athlete, or entrepreneur, which can provide them with significant income and net worth. It is also possible for these individuals to have made their fortune through investments in real estate and other assets.
