When you borrow money dont look at the fact that you owe x amount of dollars, look at what you can rent the property for v what your total costs are to hold it. If they are on par or close then you get to control an asset that has the potential to rise in value over time and to command higher rents. Someone else pays for it, your tenant and the tax man. It is possible to buy properties that are cash flow positive from day one.

Whilst I am finding many properties wherein the rent covers the interest on an interest only loan at the current low rates of sub 5% for resi IPs, I find that once you factor in PM costs, insurance, strata fees, local council levies, sundries, there is no cash flow positivity. I suspect that to get the positive cash flow, we are dependent on the tax deduction and depreciation.
