Here are some questions to think about:

  • Do I know how to save for a deposit?

  • Do I have existing savings?

  • How much can I afford to save each month?

  • How soon do I want to buy my home?

What is a mortgage?

A mortgage is a long-term loan that helps you own a property by borrowing money from a lender to cover the remaining cost after you've paid a deposit. The lender has the right to take your property if you don't repay the loan plus interest, so it's important to plan carefully and make sure you can meet the repayments. 

There are various types of mortgages, understanding them will help you when you consider which mortgage is right for you. To learn more visit our page, understanding different types of mortgages

What is a deposit?

A deposit refers to the initial amount of money that you pay upfront when buying a property. It can sometimes be referred to as a ‘down payment’, which is usually a percentage of the property’s value. The remaining cost will be financed through a mortgage.

How much deposit do I need to buy a house?

The amount of deposit that you will need to save to buy your first home will depend on the purchase price of the property that you wish to buy. The minimum deposit is usually 5%.

Other considerations

What kind of savings account do you offer?

You will only receive the government’s 25% bonus if you go on to use the savings in your LISA towards the deposit on your first home and/or towards your retirement. 

If you make a withdrawal not connected to these two events then a 25% penalty will apply to the amount you withdraw. This will recover the government’s bonus and you will get back less than you have saved.

We offer a range of savings accounts if the above aren’t the right match for you. We offer easy access accounts, fixed rate accounts, limited access and notice accounts. View all our savings products to find out more.
