Alan,
Note that a similar strategy is to borrow funds from your equity & use them to buy an annuity which then provides your income.
This has the same advantages/disadvantages as the strategy described by Dale, but can be used as serviceable income for further borrowings.
This gets around the issue of not being able to service further borrowings as may occur if you are living purely off borrowings.
The interest on the annuity is the only part that is taxable.
Remember that you do have to pay back those loans somehow during their life however - your payments could significantly cut into the income you receive from the loans.
Cheers,
