<prompt> Human: I have no debts or liabilities, and a fair bit of cash, would it be sensible to invest in say, an SP500 ETF on margin?For example: 100,000 into VOO?Quick calculations Id hold for 1 year, and have an interest rate of 7.The main reason Im thinking of this is that I look at the large gains possible on housing investment due to the large mortgages people take out. Basing all of my gains on my own money, rather than borrowed funds, seems like a slow way to get ahead.  <response>: If you understand margins well enough to consider investing using margins, you dont need our opinion. Also - this is personalfinance - youre question is more suited to investing.Good luck!
