I have recently seen a mortgage broker about organising finance for an investment property. This is the the first time I have invested, but own home with a mortgage. The meeting happened about a month ago, where he explain a lot of new concepts and terms. The meeting concluded with him putting in for an valuation on my house and submitting applications for a LoC. He has since found a LoC with Suncorp at 4.72%, and would also like me to refinance/move my home loan for my PPoR to Suncorp. He did explain the relationship between the PPoR mortgage and LoC, but given that it was a month ago, I am finding it difficult to remember who the two are related. Can anyone explain how my PPoR mortgage and LoC are related. Is it necessary to have my LoC and mortgage with the same financial institution? Or is it possible to have my PPoR mortgage with one financial provider, and my LoC with another provider? I am very new to investing. Thanks in advance.
