Closed-end Funds
Closed-end funds use borrowed funds to invest in stocks or bonds, and sometimes trade at steep discounts to the value of their underlying investments. BlackRock Enhanced Equity Dividend yields 6.5%.
Mortgage REITs
Mortgage REITs put borrowed money into pools of home loans. They will take a hit if short-term interest rates rise a lot, but they also offer juicy yields. Blackstone Mortgage Trust offers 8% and Annaly Capital Management offers 10%.
