It's interesting because it'd actually be very much in the banks self-interest if you did take your mortgage and transfer it to a better home that is now the same price as your original loan amount. Presumably a home in the same area that is valued now at a time of high interest rates the same as your current house was during the time of low interest rates will be a nicer home. Having the higher valued home as collateral is a benefit to the bank.
