If I acquire a U.S. business using no debt, just equity (from my savings, friends & family, outside investors), what % preferred annual dividend would investors expect?
What total annual return would they expect? Would they want me to sell the business in 3 to 5 years so they can realize the return on their investment? What if the business hasn't increased enough in value by the end of that period to provide the total return they wanted?
