Consolidating IP loans. Good idea?

[Mrman]

Just wondering if you have 2 IP loans, would there be an advantage in making them into 1 larger loan to possibly save on interest payments.

I'm aware there would be problems when tax time comes round as you would have to proportion the interest payments for the respective IP's.

Why do you think you'll save on interest payments? Also, I think you're talking about cross-collateralisation, which has its own benefits and problems.
