Banks are using new council valuations to call in property loans and change terms, according to mortgage-holders.
Auckland homeowner Lyndsey Thompson said he had to negotiate with his bank after his rating value was set at $1.4 million on a new-build - $550,000 less than a valuation he had conducted three years ago.
"I have considerable equity in this property and yesterday I rang to arrange a temporary overdraft and my bank said because the GV was now $1,400,000 ... they needed a new registered valuation to lend against. I service $100,000 in interest to this bank annually, plus fees on business accounts.
"They see my turnover and yet they responded with a curt response because of the new CVs.
"Great news for valuers as they are going to have to revalue a lot of properties as the banks are taking this as an excuse to call in loans and restrict borrowing," he said.
