Getting a mortgage is one of the biggest steps towards buying your first home. Having a deposit is important, but lenders also look at your income, spending, existing debts, credit history and whether the mortgage repayments are affordable for you.
There is no single checklist that guarantees approval. However, preparing your finances before applying can put you in a stronger position and may give you access to a wider choice of mortgage options.
Build as Strong a Deposit as You Can
A deposit is one of the first things to consider when preparing for a mortgage. First-time buyers will usually need at least 5% to 10% of the property’s value, although the amount required varies between mortgage products. A larger deposit can reduce the amount you need to borrow and may give you access to more competitive deals.
You do not necessarily need to delay buying until you have a very large deposit. Instead, consider what you can realistically save and how that affects the properties and mortgage options available to you.
Check Your Credit Report Before Applying
Your credit history can affect how a lender views your mortgage application. Before making an application, check your credit reports for errors, outdated information or accounts you do not recognise.
Regularly paying bills and credit commitments on time can help demonstrate responsible borrowing. If you have missed payments or outstanding debts, dealing with these issues before applying may put you in a stronger position. MoneyHelper also recommends checking your credit report before approaching mortgage lenders.
Avoid making unnecessary credit applications shortly before applying for a mortgage. Multiple applications within a short period can affect your credit profile and may make your financial situation look less stable to potential lenders.
Reduce Existing Debts Where Possible
Lenders are interested in more than your salary. They also consider your regular financial commitments when deciding whether you can afford the proposed mortgage payments. This can include loans, credit cards and other forms of borrowing.
Reducing expensive or unnecessary debt before applying can therefore help. It can also leave you with more money available each month once you become a homeowner.
You do not necessarily need to clear every debt before applying. The important thing is to understand how your existing commitments affect what you can comfortably afford.
Keep Your Spending Consistent
Mortgage lenders may review your bank statements and other financial information as part of the affordability assessment. They want to understand how much money comes into your account and where it goes.
This does not mean you need to stop spending on everything you enjoy. However, regularly relying on overdrafts, struggling to cover bills or taking on significant new borrowing could make your finances harder to assess.
Keeping your spending under control for several months before applying can make it easier to demonstrate that you can manage your money and afford future mortgage payments.
Make Your Income Easy to Evidence
Having a reliable income is important when applying for a mortgage because lenders need evidence that you can maintain the repayments.
If you are employed, you may be asked for documents such as payslips and bank statements. If you are self-employed, lenders can request additional evidence such as tax returns and business accounts. The exact requirements vary between lenders.
Keep important financial documents organised so that you can provide accurate information when requested. If your income varies, explaining how it is earned and providing consistent records can also help a lender understand your circumstances.
Think Carefully Before Changing Jobs
Changing jobs is not automatically a problem when applying for a mortgage, but the timing can matter. If you are planning to apply soon, consider how a change in employment could affect your income history or the documents you need to provide.
This can be particularly relevant if you are moving from permanent employment to self-employment, starting a new role with a probationary period or moving to a position where your income depends heavily on commission.
If you are considering a major employment change, speaking to a regulated mortgage adviser before making the move can help you understand how it may affect your options.
Know What You Can Comfortably Afford
Getting the largest mortgage a lender is prepared to offer does not necessarily mean it is the right mortgage for you. Your own budget should leave room for household bills, food, transport, insurance, maintenance and unexpected expenses.
Lenders are required to assess whether a mortgage is affordable, taking income and expenditure into account.
Before looking at properties, work out what monthly payment you would be comfortable with rather than starting with the maximum amount you might be able to borrow.
Do Not Forget the Costs Beyond the Mortgage
Your mortgage payment will not be your only housing expense. Buying a home can also involve solicitor or conveyancer fees, surveys, mortgage fees, insurance, moving costs and taxes where applicable.
Once you own the property, you will also need to budget for repairs and maintenance. Keeping some savings aside after paying your deposit can therefore be just as important as reaching the deposit target itself.
A strong mortgage application should lead to a home you can afford to maintain, not simply one you can afford to purchase.
Consider Using a Mortgage Adviser
You can approach a bank or building society directly, but a regulated mortgage adviser or broker can also help you understand the range of options available. This can be particularly useful if you have a smaller deposit, are self-employed or have circumstances that may require a more specialist mortgage.
An adviser can help you understand which lenders may be more suitable for your circumstances before you make a full application.
This does not guarantee acceptance, but it can help you avoid applying for mortgages that are unlikely to suit your financial position.
Understand Your Local Property Market
Your mortgage options are closely connected to the price of the property you want to buy. Looking at realistic property prices in your preferred area can therefore help you decide how much deposit you need and what level of borrowing may be appropriate.
If you are a first-time buyer in Doncaster, understanding the local market can help you set a more realistic buying budget. Different neighbourhoods and property types can have very different price points, so looking beyond a single average can be useful.
Professional estate agents in Doncaster can help you understand the types of homes available locally, current buyer demand and which areas may offer properties within your budget.
Avoid Rushing Into an Application
Preparation can make the mortgage process considerably easier. Check your credit report, review your spending, organise your income documents, reduce unnecessary debts and build as much of a deposit as you reasonably can before making an application.
It is also worth remembering that mortgage lending rules and products can change. In June 2026, the FCA proposed changes intended to help more creditworthy consumers access suitable mortgages while keeping affordability checks in place. These proposals include greater flexibility for some borrowers with variable income or previous credit difficulties, but they are proposals rather than rules that applicants can currently rely on.
Final Thoughts
Improving your mortgage chances is mainly about putting your finances in good order before you apply. A healthy deposit, manageable debts, consistent spending, reliable income records and a clean credit history can all help present a stronger application.
Just as importantly, focus on buying a property that fits your budget rather than borrowing the maximum available. Taking time to prepare can give you a clearer idea of what you can afford and help make your first move into homeownership more sustainable.
