Where can I borrow money for investing?
If you are looking for money to speculate in the capital markets, then your brokers will already lend to you at a MUCH more favorable rate than an outside party will. For instance, with $4,000 you could EASILY control $40,000 with many brokers, at a 1% interest rate. This is 10:1 leverage, much like how US banks operate... every dollar that you deposit with them, they speculate with 10x as much. Interactive Brokers will do this for you with your current credit score. They are very reputable and clear through Goldman Sachs, so although reputable is subjective in the investment banking world, you won't have to worry the federal government raiding them or anything. If you are investing in currencies than you can easily do 50:1 leverage as an American, or 100:1 as anyone else. This means with only $400 dollars you can control $40,000 account. If you are investing in the futures market, then there are many many ways to double and triple and quadruple your leverage at the lowest interests rates. Any contract you enter into is a loan from the market. You have to understand, that if you did happen to have $40,000 of your own money, then you could get $4,000,000 account size for speculating, at 1% interest. Again, these are QUICK ways to lose your money and owe a lot more! So I'd really advise against it. A margin call in the futures market can destroy you. I advise you to just think more efficiently until you come up with a way to earn that much money initially, and then speculate.
