Why overpay your mortgage?

If you can afford to do it, overpaying your mortgage can be a great way of saving money in the long run. This is because, by clearing the debt quicker, you'll spend less time paying interest on what you owe - which can mean saving thousands of pounds.

In the shorter term, overpaying your mortgage can also help you get a better deal when you come to remortgage. This is because you'll own a greater proportion of your home, meaning you can borrow at a lower LTV (loan-to-value ratio) - which often means better rates.

But, only overpay what you can afford to as you'll no longer have easy access to those funds.
