A savings account is probably the safest place for any investment, but it comes with a serious problem, especially in today's economic environment. Although your money at the bank will be safe and your return is guaranteed, you'll lose purchasing power due to the rapid inflation in today's markets. This is because banks don't offer a high rate of enough return. Among very safe investments, multifamily real estate is the best. Since they cost millions of dollars, you can invest in one fractionally through syndication.
