im looking for some insurance that will mean if either my fiancee or i die our house will be paid off in full (this way our kids have a home) im still quite young (38) any one know any good companys to get a quote with?

OK, this is plain old life insurance.

Your best bet is to go to the guy that writes the house insurance, and get quotes for life insurance. YOu probably want term, as eventually that mortgage is going to get paid off, anyway, and then the "goal" disappears.
