Both variable, but not to save money on monthly repayments - just because of the break fees, because we are likely to pay either or both loans out very very early. With our situation, which is normally self-employed but just coming out of a long break to create a small destructive humanoid, looks like we won't be able to get any more lodocs until we've got our earnings way up or the LVR way down.
Current grand plan is just maximising income. Get the PPoR loan down, get the IP rented out, and get the IP debt down to well under $50k. Then at least if we miss out on the COMET grant for whatever reason (and I can think of several), we can at least loan 60% for a big business kickstart. Seems a shame to sell something that will be so positively geared if we have the option to lend againt it instead.
My PPoR is more of a liability than an asset though, really need to just pay that out and be done with it.
