The magic of financial leverage in calculating ROI profit

Leverage is the art of getting rich using the bank's money. Instead of buying one apartment for a million in cash, you buy five such apartments, putting down 20% of your own funds for each. When the market grows by 10%, you earn that percentage on the value of five properties, astronomically pumping your profits. However, this sophisticated mechanism does not tolerate unnecessary upfront costs. Investors using leverage cut useless margins and hunt exclusively for direct sales offers (off-market).
