MO has already brought Master Fire Policy that most of the bank are aceepted. (That is paid by our Mgt Fee) However HSBC required a higher standard policy which includes explosion; Earthquake; Typhoon windstorm & flood; Landslide & Subsidence. That's why those have mortgage with HSBC will need to buy the Fire Insurance that meet their standard.
Hi YY & KC
In my case I called the branch manager (the one handling my mortgage)
and discussed my case. He kept his word the insured sum (original is the same as mortgage amount) is half of it after the revaluation. Therefore the premium is also half of it.
However I asked another insurance co the premium will be 15% less than HSBC. At present I'm still comparing the quotation if you need any information please PM me. Thanks.
