If you want to own stocks instead, find a low margin interest rate broker (eg. IBKR), put your money in there, and down the road if you have profits and don't want to realize them (because you will pay cap gains), you can take out a loan against said stock at a low rate (IBKR is sub 1%). Note that this is quite risky, make sure you manage your risk well.

You should also spend a lot of time reading about investing and risk management. Margin of Safety, Intelligent Investor, The Art of Investing, etc.

Make sure to study your tax code as well; don't get screwed over by wash sale taxes. Find a good accountant! Just walk into a branch of the big four accounting firms (Deloitte, E&Y, KPMG, PWC) and you will probably find one.
