How can anyone answer this?? Its dependent on so many factors, quality of asset, cash flow of portfolio, LVR, your age, what you are trying to achieve in terms of income etc etc.
My thoughts exactly if the debt can be serviced without trouble you shouldn't have a lid, just wanted to know if it was the same thought process all round
Servicing the debt is part of the story, but you can not give up your day job doing this. Next step is replace your income. So then you probably need to be active investor not passive and look at strategies to reduce debt.
