Op. When you’re on a repayment mortgage. The capital sum reduces. Which means the interest does, as the more you pay off the capital sum, the more it reduces and then the interest is applied to the continuing reduced capital sum, so it’s less as its interest charged on a Lower amount.
most people then keep their repayments higher, basically the same as before, or close to, as the interest reduces, meaning they overpay the capital sum each year to what is permitted in the mortgage terms, often ten percent, which then again reduces the interest due, as the capital sum is constantly being paid down.
after 15 years a significant amount of the initial amount borrowed would be paid down, giving vastly reduced interest due, allowing many people to pay off early. Or they just pay the reduced amounts and clearing it after the 25 years or however long they borrowed for.
a mortgage is simply a loan, like a credit card or any other type of loan. You need to pay back what you initially borrowed, not just the interest on it.
paying it down means your home is protected, should anything happen to either of you or your jobs. As a mortgage is a loan where you used the property as security, the lender has a charge over it. And any inability to pay can see them force a sale and take their money back, inc Any interest owed. A repossession. Every single person whose home has been repossessed could comfortably afford the repayments when they first borrowed.
the amount of interest you have paid will be shocking. As your capital sum you borrowed bas never been touched, as such the interest was always on the maximum amount, it never ever reduced as you never touched the initial borrowing.
as such, the choices you’ve made have cost you thousands and thousands in additional interest payments, if you did the exercise to total up how much more in interest you’ve paid every year as the repayment sum was never reduced and interest applied to the full amount, it would be horrifying. Plus at the end of the mortgage, the full sum is still repayable.
in reality you’ve not just spent what you’ve earned, you’ve been basically borrowing heavily to do it, every single day you don’t pay anything to that initial sum is another day you’re borrowing it.
