LOC against two properties?

I got my second property secured by itself and my home.
Can I take a line of credit against my home or I have to take it out against both properties?
Hi pete

Any further loan can usually be secured against either or both properties.

while u are sorting out your new LOC u could self secure he IP as well w?

Thanks for your reply Rolf.
Beacuse of both properties have been used to secured the second loan, how can I calculate what's the available equity left from my home for the loc?
