The investments available through 22seven are recommended as at least five year investments. And, generally, the longer you leave them, the better they’re likely to do for you.
They’re unit trust funds, which go up and down in the short term but, historically, have gone up in the long-term. So, although you are able to withdraw money from the funds any time without paying penalties, the idea is to leave your money there for as long as possible.
If you think you may need or want the money within a year or two, you might want to consider a different kind of investment or savings account that is more appropriate for a shorter period of time.
