Hi Jason,

The only advice I can give is that I myself am looking at my 4th property and the insurance (I think) you're referring to is mortgage lenders insurance.

In my situation this insurance applies when you're borrowing over 80% (maybe less depending on where you're borrowing from) of your current asset value.

e.g. current property value = $200k therefore anything more than 80% of $200k ($160) will incur mortgage lenders insurance.

I've had to pay it on one occasion a few years back and for a $200k loan it was roughly a once off $5000. The best way to get an idea of how much insurance they'll charge is to call them and ask.

Hope this helps,
