Your payments will be similar to what they were before your payment break.
The agreed missed monthly payments and interest will be added to your mortgage balance.
Here's an example of how this would work:
Issac’s 3 month payment break.
Isaac took a 3 month payment break. He has a repayment mortgage of £160,000 on an interest rate of 4.00% and he has 24 years and 1 month left on his mortgage. His monthly payment before he took a payment break was £863.32 each month.
After a 3 month payment break, Isaac added his agreed missed payments and interest to his mortgage and extended the term by 3 months. His new monthly mortgage payments are now £872.03 an increase of £8.71 each month. Overall Isaac will pay £2517.19 in additional interest over the term of his mortgage and he now has 24 years and 4 months left on his mortgage.
