I know a guy who's a multimillionaire. He came up from nothing and always had the mindset that if you have to finance it, you can't afford it. A few years ago, he wanted to purchase an apartment complex, but was short by something like $500,000. He tried to get a loan, but the bank wouldn't give him one because he had no credit. Instead, he sold two of his supercars to cover the difference and bought the complex.
