Give me a museum and I'll fill it. (Picasso) Give me a forum ...
^^^ Not sure where you are getting that "financial advisors insist mortgages should be compared to, or paid off by, fixed income investments rather than one’s equities"... I've never run across that but it is a sensible comparison because both are fixed income/fixed expense and similar financial risk.
I think the more sensible approach is to compare the mortgage interest rate to the yield of the investments that would be liquidated to pay off the mortgage. If the subject pays of the mortgage and doesn't adjust their AA, then in effect they avoid mortgage interest at the opportunity cost of the expected yield of a portfolio with that AA... and historically in most cases that has been a financially poor decision.
On the other hand, if the mortgage will be paid off with cash or fixed income investments that are earning less than the mortgage interest rate and the subject adjusts their AA to reflect it, then it likely a financially wise decision.
