I know on loan applications for Equity/LOC for the particular bank I use to pull some more for property deposits etc has a "declaration of purpose" and a warning that I should not sign unless the loan is used predominantly for business or investment purposes. Now, let's say, I want to use one of these loans for "private" purposes ie, the purchase of a motor vehicle for example. Now I know the interest on this loan in this instance cannot be tax deductible, and I don't expect it to be! But what is the ramifications if it is used for private and not investment?
