I tried this recently with the NAB, but was told that about 6-12 months ago the mortgage insurers have changed thair policy and no longer allow for the refunds. Main reason was due to the very strong property market which was leading to a very large increase in applications for refunds. It was obviously costing the mortgage insurers too much so they decided they didn't want to play ball any more.
for Rolf - do you have any evidence of any banks allowing for the refunds recently??
