1. What Is a Mortgage?

A mortgage is a loan secured against property. If repayments are not maintained, the lender may repossess the property.

2. How Much Can You Borrow?

Most lenders offer between 4x to 4.5x your annual income, depending on your financial profile.

Example: If your salary is £40,000, you may borrow approximately £160,000–£180,000.

Affordability Checks Include:

  • Income level
  • Employment status
  • Existing debts
  • Credit history
  • Monthly expenses

3. Deposit Requirements

  • 5% – Minimum deposit
  • 10% – Better interest rates
  • 20%+ – Lower risk category

A larger deposit reduces your Loan-to-Value (LTV) ratio and can significantly reduce monthly repayments.

4. Types of Mortgages

Always check whether fees are added to the loan or paid upfront.

6. Documents Required

  • Bank statements
  • Proof of ID
  • Proof of address

7. Improving Your Approval Chances

  • Reduce existing debt
  • Avoid new credit applications

  • Improve credit score
  • Save larger deposit

8. Mortgage Protection

This protects your home in case of unexpected circumstances.
