Improve Your Chances of Getting a Mortgage

Applying for a mortgage is more than filling in an application form. Lenders assess risk and affordability using information from your credit history, income and outgoings, deposit position, and the evidence you provide.

If you want to improve your chances of a smooth application, the most effective approach is to make your financial picture easy to understand, consistent, and well supported by documents.

This guide explains the main areas lenders typically focus on and what you can do before you apply.

How lenders assess mortgage applications (in plain English)

Most mortgage decisions come down to two broad questions:

1. Can you afford the repayments? Lenders look at your income, your existing commitments, and how much of your budget would be taken up by the mortgage.

2. How reliable is your financial behaviour? Your credit history and overall money management help lenders judge how likely you are to meet repayments.

Your deposit and the loan-to-value (LTV) also influence how lenders view the risk of the mortgage.

1) Credit history: what matters and how to strengthen it

Your credit file is used to understand how you’ve managed borrowing and payments over time. While a “good” credit score can help, lenders also consider patterns such as missed payments, defaults, and the way you use credit.

Focus on the behaviours lenders look for

• On-time payment history: set up reminders or direct debits so bills and credit commitments are paid consistently.
• Credit utilisation: if you have credit cards or overdrafts, keep balances under control. High usage can be viewed as higher risk.
• Avoid unnecessary credit activity: applying for additional credit shortly before a mortgage application can complicate affordability checks.
• Keep your address details consistent: lenders may use electoral roll and address history to help confirm identity.

Soft checks vs hard checks

Checking your own credit file is usually a soft search and won’t normally damage your score. A hard search can happen when you submit a mortgage application and may be visible to lenders.

To avoid unnecessary impact, it’s best not to make multiple mortgage applications in quick succession.

2) Deposit and loan-to-value (LTV): why it affects your outcome

Your deposit is the part of the purchase price you pay upfront. The smaller the deposit, the higher the LTV (the loan amount compared to the property value).

In general terms:

• Lower LTV can improve lender comfort because there’s less borrowing relative to the property value.
• A larger deposit can broaden options and may help you access more competitive mortgage products.

Evidence of deposit is essential

Lenders will typically require proof that your deposit is available and that it comes from an acceptable source. This commonly includes:

• bank statements and savings records
• documentation for gifted deposits (where applicable)

Having this information ready can reduce delays and prevent avoidable questions during underwriting.

3) Debt-to-income and affordability: make your monthly picture add up

Affordability checks consider your monthly income against your monthly commitments.

This isn’t just about loans. Lenders may include repayments for:

• credit cards
• personal loans
• existing mortgages or rent (where relevant)
• other regular financial commitments

How to improve your affordability position

• Reduce existing debt where possible before applying.
• Avoid taking on new credit in the months leading up to your application.
• Be realistic about your outgoings: lenders will look at what you can evidence.

Even small improvements—like paying down a credit card balance—can help your overall affordability assessment.

4) Job stability and income: consistency helps

Lenders want confidence that your income is reliable enough to support mortgage repayments.

Employment types lenders commonly review

• Permanent employment is often viewed as more stable.
• Fixed-term contracts may be acceptable depending on the length of the contract and your history.
• Self-employed income usually requires more evidence to show how income is calculated and how consistent it has been.

If you’ve changed jobs recently

A job change doesn’t automatically rule you out. What matters is whether you can provide evidence of your new role and income, and whether your overall employment pattern supports the lender’s affordability and risk assessment.

5) Mortgage Agreement in Principle (AIP): useful, but not a guarantee

An AIP is often used to help you understand what you might be able to borrow, based on information provided at the time.

However, it is typically not the final decision. Your full application will still be assessed with deeper checks, including credit history, income verification, and property-related requirements.

6) Documents: the fastest way to avoid delays

One of the most common reasons mortgage applications stall is missing or unclear paperwork. Lenders use documents to verify identity, income, outgoings, and deposit sources.

Typical documents lenders may request

• Proof of identity (e.g., passport or driving licence)
• Proof of address (often recent utility bills or council tax statements)
• Income evidence
  • payslips and P60 (where applicable)
  • employment contract and/or additional documents depending on circumstances
  • self-employed applicants may need tax returns and accounts
• Bank statements (commonly covering several months)
• Proof of deposit (statements and/or gifted deposit evidence)

If you’re organised and consistent with your documents, it can make the underwriting process smoother.

7) Common mistakes that can reduce your chances

Even well-prepared applicants can accidentally weaken their application. Common pitfalls include:

• Overusing credit cards or taking on new loans before the application is complete.
• Making frequent credit applications in a short period.
• Missing payments on any financial commitments.
• Changing your financial position after submitting an application (for example, large unexplained transactions or new credit agreements).
• Submitting incomplete or inconsistent information, especially where evidence doesn’t match the application details.

If your finances aren’t perfect, it can still be possible to apply successfully—what matters is addressing avoidable issues and ensuring your application is supported by clear evidence.

Quick checklist before you apply

Use this as a practical pre-application review:

• Your credit file is accurate and up to date
• You’ve avoided unnecessary new credit activity
• Your deposit is available and can be evidenced
• Your monthly commitments are manageable against your income
• Your employment and income can be supported with documents
• You have the main documents ready (identity, address, income, statements)

Frequently asked questions

Can I improve my chances if my income is low?

Often, the most effective levers are deposit size and reducing existing debt. Some applicants may also consider joint applications, depending on their circumstances. The key is presenting a clear affordability picture with supporting evidence.

Is it harder to get a mortgage if I’m self-employed?

Self-employed applicants can face extra scrutiny because income can be more variable. The process is still possible, but lenders usually require more documentation to understand how income is calculated and how consistent it is.

What if I have a gap in employment or I’ve recently changed jobs?

A gap or job change doesn’t automatically prevent approval. Lenders typically assess the overall reliability of income and may request additional evidence. Consistency and clear documentation are important.

Can I still be approved if my credit isn’t perfect?

Yes, it can be possible. However, your options may be more limited and lenders may apply stricter conditions. The best approach is to ensure the rest of your application—deposit, affordability, and documentation—is as strong as possible.

Will an Agreement in Principle guarantee I’ll get the mortgage?

No. An AIP is an estimate based on initial information. The final decision depends on the full application checks, including credit, income verification, and the property.

Final thoughts

Improving your mortgage application is usually about reducing uncertainty for the lender: clear credit behaviour, a deposit you can evidence, an affordability picture that makes sense, and documents that match your application.

If you’re preparing to apply, taking time to tidy up these areas can help you avoid delays and give your application the best possible foundation.
