What is a Mortgage?
A mortgage is a loan used to buy property or land. You borrow money from a lender and repay it over time, usually with interest.
In the UK, mortgage payments typically include:
- Loan repayment (capital)

The total amount you borrow after your deposit.
2. Interest Rate
The percentage charged by the lender on your loan.
3. Mortgage Term
The length of time you take to repay the loan (e.g. 20–30 years).
