Mortgage Repayments 101

Answers to all the key mortgage repayment questions. No jargon. No fluff. Just real guidance to help you feel in control of your mortgage journey.

Several factors will impact what your mortgage repayments will be, mainly:

  • The size of your mortgage loan

  • Your deposit

  • The interest rate and type of mortgage you select

  • Your mortgage term

When comparing different mortgage deals, small differences in any of the above could have a big effect on your repayments.

Our mortgage repayment calculator is a quick and easy tool that gives you an idea of your monthly repayments in seconds. Remember, these figures are a guide. Your exact repayments will depend on what the outcome is for all of the above factors.

As a general rule of thumb, most mortgage lenders will offer around 4 to 4.5 times your annual income as a mortgage. This is usually the starting point. Lenders will then look further at your income and outgoings, the size of your deposit, age, and credit history to assess your overall affordability. 

To get a rough idea, you can use our mortgage affordability calculator.

Everyone’s situation is different. At Picnic, our mortgage team can help you figure out exactly how much you can borrow based on your own personal circumstances. Just click the button below to make an enquiry, and we’ll help you get started. 

Most traditional mortgage terms are 25 years, but they can be both shorter or longer, depending on your circumstances. Some lenders offer mortgages for just 5 years if that’s affordable to the applicant and acceptable to the lender.

Longer-term mortgages, up to 45 years, are now available and designed to help make mortgage repayments as affordable as possible. 

There are two main ways to repay your mortgage: capital and repayment, or interest-only. 

If you’re buying a home to live in, capital and repayment mortgages are by far the most common choice. Interest-only mortgages are typically only used for buying investment properties, such as buy-to-let.
