Key Factors That Affect Your Mortgage Borrowing Potential
Understanding what influences your borrowing limit helps you prepare better. Here are the main factors lenders consider:
Income
Your income is the biggest factor. Lenders usually offer between 4 to 5 times your annual income. If you have a partner, their income can be added too. Self-employed individuals may need to provide additional proof of earnings.
Outgoings and Debts
Lenders look at your monthly expenses, including bills, loans, and credit card payments. High outgoings reduce the amount you can borrow. It’s important to be honest about your spending.
Credit History
A good credit score improves your chances of borrowing more. Lenders check your credit report to see if you have a history of missed payments or defaults.
Deposit Size
The size of your deposit affects the mortgage amount. A larger deposit means you need to borrow less, which can improve your borrowing potential and mortgage terms.
Employment Status
Permanent employees usually have an easier time getting a mortgage. If you are on a fixed-term contract or self-employed, lenders may be more cautious.

How to Improve Your Mortgage Borrowing Potential
If your borrowing potential is lower than you expected, don’t worry. There are steps you can take to improve it:
Reduce Your Debts
Pay off credit cards and loans to lower your monthly outgoings.
Increase Your Income
Consider additional income sources or ask for a pay rise.
Save a Larger Deposit
The bigger your deposit, the less you need to borrow.
Check Your Credit Report
Fix any errors and improve your credit score by making payments on time.
Limit New Credit Applications
Avoid applying for new credit before your mortgage application.

A mortgage adviser can help you find lenders that suit your profile and maximise your borrowing potential.
