It's worth reiterating the purposes for wanting to remortgage and questioning whether they remain a valid reason right now, or identifying whether the decision should be put off for the time being:
Availability of different and more appropriate mortgage products - a better rate or payment terms on a different mortgage product, which makes repayments more beneficial and manageable.
Borrowing money for specific projects - taking out some of the equity accrued in your home to pay for a variety of projects.
Changes in circumstances - marital status, financial position, etc. There are many reasons why your change of circumstances might inform your decision to remortgage.
Buying a second property - perhaps to get into the rental business, or to supplement your child's step up on the property ladder.
