I agree with this. Someone, unfortunately most likely your husband, has been misleading you for years on this.
We took a £330,000 mortgage 10 years ago. We overpay but only by around £150-200 a month and our balance is down to £238,000, so we've paid off 28% of our balance in 10 years.
There are various free loan calculators online, or even Excel has some templates built in.
I just used one that shows a £245,000 25 year mortgage at 5.5% interest, taken out 20 years ago, should now have a balance of around £79,000. Repayments would be £1,500 a month.
£79,000 compared to £203,000 is a massive difference, not explained away by a few £000 extra being taken at each remortgage.
If you still owe £203,000 then one of a few things has happened (or a combination):
- you had a really, really shit deal at some point
- you went on to an interest only mortgage at some point and didn't repay any capital at all for a period
- the extra borrowings on each remortgage are much more than you thought they were - the reasons for that you'd obviously have to discuss with your husband.
Something has gone very, very wrong with this. You really should have been clear of your mortgage by now.
Good luck OP
