    Don't Be Fully Invested

    While I encourage everyone to invest as much as possible, I’d also like to advice you to not be fully invested.

Generally, for almost all kinds of loans the return on investment is usually lower than the loan interest. One exception is home loan which has a much lower effective interest rate because you get tax benefits. For most other loans it is better to prepay. That is a very simplistic rule, but does it really work? Let’s find out.
