A "cheap" minor league team will cost you between $5 million & $25 million, so to make that much investing in ETFs, which may return you 7-10% a year, you'll need to start off with between $1M & $5M and invest it for about 20 years...
My dream is to own Professional sports teams. I want to start off with ETF's and then raise enough money to buy a minor league team then eventually Pro teams. How can I start off?
