1. How to Access Healthcare REITs Via ETFs

High-yielding, income-generating asset classes are benefiting this year as Treasury yields decline and the Federal Reserve puts off another interest rate increase. The group of beneficiaries includes exchange traded funds holding real estate investment trusts (REITs).

Within the REIT space, long-term investors may want to consider those ETFs with exposure to healthcare REITs, which are plays on the aging U.S. population. The Vanguard REIT ETF (NYSEArca: VNQ), SPDR Dow Jones REIT ETF (NYSEArca: RWR)and iShares Dow Jones US Real Estate Index Fund (NYSEArca: IYR) are among the most popular REIT ETF plays. While these are some of the top-performing sector funds this year another fund gives investors exposure to healthcare REITs.

7. High Yields: Love ‘em if You Can Leave ‘em
