This page provides general information. For more specific and tailored information please contact your mortgage intermediary
When you take out a mortgage with New Street or any other lender, you will need to repay it. All our mortgages require our customers to make regular monthly payments. If you are experiencing difficulties doing this, or expect that you are about to, please see our Help with Repayments page.
Types of mortgage
New Street offers repayment, interest only and part-and-part mortgage options. Your intermediary should have explained the options available to you and you can see which type of mortgage payments you make in your mortgage offer letter.
If you have a repayment mortgage this means your monthly payments reduce the amount you owe us as well as paying off interest. If you make all your payments on time and in full your mortgage will be repaid by the end of the term.
If you have an interest-only mortgage this means your monthly payments only pay off the interest on your mortgage and do not pay off the mortgage amount. This means that although your monthly payments will be less than if you had a repayment mortgage the amount of interest you will have to pay will be higher than if you had a repayment mortgage as you will be paying interest on the full mortgage amount over the full term of our agreement with you. You will also need to make separate arrangements to repay the full mortgage amount at the end of our agreement with you, for example by starting a savings plan.
We may ask you for details of your repayment strategy from time to time and ask you to confirm this is on track to repay the mortgage amount at the end of our agreement with you.
Part and Part mortgage
You may have a mortgage which is part repayment and part interest only. If part of your mortgage is interest only you will only be paying interest on this part and you will need to make separate arrangements to repay the mortgage amount for that part at the end of our agreement with you.
New Street Mortgages – Lender Base Rate Setting Policy
Your mortgage interest rate affects the amount you have to pay each month. If you have a fixed rate mortgage, your interest rate will not change for the duration of the fixed term. If you have a variable interest rate mortgage, or your fixed term has come to an end, your interest rate may change from time to time. You can find out what type of interest rate applies to your mortgage, and how long any fixed term will last, in your mortgage offer letter.
