I have twice had banks threaten to "call in" a loan.
The first was after a major conveyancing error on my solicitor's part, causing the lender to say that the asset wasn't worth as much as they'd thought and therefore they wanted to call in the loan. I managed to delay them by promising to refinance, which I did.
The second was during our prolonged dispute over PPOR repairs after our home was destroyed in the Jan 11 Brisbane floods. We managed to pay rent on a temporary home and keep our mortgage up to date, but the bank was saying that as our home was uninhabitable, and our insurance claim had been denied, they had no valuable asset securing our mortgage and thus were planning to call in the loan. Their argument was that our PPOR was worth less than land value only (because they subtracted demolition costs from land value), and our mortgage was much more than that, so they had a right to call it in.
I held them off by lodging a complaint with the Financial Ombudsman Service (FOS), and fortunately my parallel complaint regarding the insurance matter with the same agency, was resolved in our favour before matters came to a head.
I have never felt under so much stress.
We did nothing wrong; we had a natural disaster for which we'd done the responsible thing and *had* insurance (including for flood; that wasn't the issue). But purely because our insurers were a pack of pricks, and even though we continued to pay our mortgage and rent on emergency accommodation, we nearly lost
everything.
Even though we ultimately prevailed, the stress nearly sent me 'round the twist.
