@rauch I agree. This is called leveraging and businesses do it all the time.
However, OP, if you borrowed the money from your friend in good faith at zero interest, then don't be an asshole. Pay that person ASAP.
@danaross67
Monthly add-on rate is not the same as monthly interest rate.
If the monthly add-on rate is 0.45%, then the effective interest rate would be 9.8%.
Borrowing at 9.8% and then investing in a time deposit with a net gain of only 5.6% would then be ridiculously stupid.
@jggray6 I have a bunch of common shares, too.
Preferred shares in general are less liquid compared to common shares and REITs. However, you don't really need liquidity if you plan on holding until the redemption date/step up date. Until then, you just enjoy the dividends.
@maryeldermusic Just open a stock brokerage account like BPI Trade or COL.
They will notify you of newly offered preferred shares/REITs.
You can also just buy the existing ones using your broker.
@muiris Borrowing money to make more money is called leverage. Busineses do it all the time.
However, in your family's case, if you don't even know where to put the money, then borrowing money would be a stupid idea.
