What is a mortgage?
A type of loan you can use to help you buy a house or a flat, or another type of property.
- You'll usually need to pay a deposit up front, and then you can apply to borrow the rest you need from a lender to cover the purchase price of the property.
- A mortgage is usually a long-term loan that can last for different lengths of time.
- You can choose a mortgage term to help spread the cost of the mortgage anywhere between 5 to 40 years usually.
What type of mortgage can I get?
There are different types of mortgages you can choose from and they have interest rates that can be fixed or variable which will impact your monthly repayments.
- Your interest rate is guaranteed for a set period.
- Monthly payments won't change until a specified date.
- You can fix your mortgage interest rate for between 2 and 5 years, up to 10 years, or longer.
- Your interest rate is usually linked to the Bank of England's (BoE) Base Rate, plus a percentage amount set by the lender.
- The mortgage interest rate can vary throughout the tracker period.
- Your interest rate is set by your lender.
- It's usually the rate you'd automatically move onto at the end of a fixed or tracker deal.
- SVRs tend to have higher rates than a lender's fixed or tracker products.
- Gives you a discount on the lender's SVR, for a set period of time.
- The discounted rate will move up and down, in line with the lender's SVR.
- A loan for a property where your monthly repayment covers just the interest on the amount you borrowed.
- You won't be repaying the amount you borrowed. This will need to be paid in full when the mortgage term ends, so you'll need to have a financial repayment plan in place to show the lender how you'll pay off the final amount.

Our Mortgage Calculator will give you an idea of how much you might be able to borrow from a lender and how much your monthly payments might be. The estimate will take into account how much you earn before tax and pension contributions are taken off, if you’re buying with anyone else, and you can refine your estimate by including any credit card debt or overdrafts, and monthly financial commitments, like loan payments and childcare costs.
Other factors for your estimate include your deposit amount, preferred mortgage term and the type of property you are looking to buy will be included. You’ll then get a breakdown of your borrowing chances, and see if you’re likely to be approved for a Mortgage in Principle.
A Mortgage in Principle, or MIP for short, is also known as an Agreement in Principle, Decision in Principle, Mortgage Agreement in Principle, or a Mortgage Promise. It’s a personalised document confirming an amount of money which a lender believes they would be able to lend you, based on the information you’ve shared in your application.
A Mortgage in Principle is specific to you and, together with your deposit, it can give you an indication of the property price range you can search within. So you can search for your new home with more confidence.
