Today I received letters from Bankwest telling me that 4 of my IP loans are increasing by 0.32% each. The letter states that: Regulatory measures have resulted in mortgage lenders implementing various changes to home loans. It makes no mention of any regulatory authority, what the regulations are nor where to read more about them. Just that one sentence. It then says: One of the changes that Bankwest is introducing is to differentiate between property investor and owner occupied home loan interest rates. And I note it specifically says that "Bankwest is introducing"...not any regulatory authorities etc. It is purely Bankwest policy. It then says it has identified our 4 loans as investment and that our Loan Contract will be varied to the Investor Variable Reference Rate, which is 5.79%. Two of my loans will get a 1.01% interest discount and the other two will get 1.05% discount. All up though all of my loans increase by 0.32% each exactly. So my question is, has anyone else received such letters from their bank? I just am baffled by the justification to pull new interest rates out of their backside by stating "regulatory measures" and then not saying what they are and why they impact a rate increase anyway. And then also stating that they have decided to identify the loans as investment and I wonder why does that need a rate increase anyway.
