Can I borrow against my share portfolio to buy an investment property?

Q.

Can I borrow against my share portfolio to buy an investment property, rather than selling an asset I want to keep and creating a CGT problem?

It would be better to buy against your home if you have one with a substantial equity as you can borrow much more against the security of real estate than you can against shares. However, if you have a large parcel of blue chip shares, and a good relationship with your bank, and have a good income, you should still be able to use the equity in the shares to buy the property.
