I have been told that there are lenders offering long term LOC's e.g. 25 years. In light of this can the following be done and is there any benefit? Instead of using P & I and Offset accounts or a redraw facility, how about having 2 LOC's attached to your PPOR, one for non-deductible debt and one for deductible debt. All your salary and other incomes ( e.g. Rental income, dividends, etc. ) goes into the non-deductible LOC and is drawn out when needed to pay any committments. This has the same effect as an offset account and the debt is never paid down.
