I definitely know that we are so lucky not to be struggling right now so please don't take this as that kind of post.
Now we are working from home we are both saving on commuting costs. As we get the train into London this runs into hundreds of pounds each month and we want to overpay on the mortgage.
We have our house that's on a 5 year fixed rate mortgage. The rate is 2.6%.
We also have a rental flat that's now (legitimately) on a standard variable rate mortgage - around 1.2%.
Both mortgages allow overpayments well above the amount we are thinking of.
Does anyone in mortgage & finance know the which to overpay the most from the capital?
