Next year my current mortgage rate ends. It's currently 1.54%. The balance outstanding when the deal ends will be circa £20k. If I remortgage, I think the rate will go up to about 4%. It doesn't affect the repayments that much, as they are low anyway.
I currently have enough in my ISA to repay it in full, and have been planning to do this.
Am I overlooking anything? Is there any reason I would be better to just keep the money in my ISA (which pays 4%) and remortgage at 4%?
If I did repay it, I'd have about £30k left in the ISA, with a few lump sums due in 2028 from pensions to top it up further, so it still feels like there's enough cash there.
Am I missing anything oh wise ones?
