How to get a mortgage in 2026: step-by-step guide, requirements & approval tips

Getting a mortgage can seem complicated at first, especially for first-time buyers. But in practice, the process is fairly structured: understand your budget, prepare your documents, compare lenders, and complete the application.

In 2026, lenders continue to focus heavily on affordability, credit history, and deposit size. The better prepared you are before applying, the smoother the process usually becomes. This guide explains how to get a mortgage step by step, what lenders look for, how much you may be able to borrow, and how to improve your chances of approval.

What is a mortgage and how does it work?

A mortgage is a loan secured against a property. The lender provides money to buy the home, and you repay it over time through monthly payments. These payments usually include the loan amount itself (principal) and the interest charged by the lender.

Because the mortgage is secured against the property, the lender can repossess the home if repayments are not maintained. Most mortgages in the UK last between 25 and 35 years, although shorter and longer terms are also possible depending on affordability.

Step 1 — Check how much you can afford

Before looking at properties, it’s important to understand your realistic budget. Lenders assess affordability using:

• income
• monthly expenses
• existing debts
• future rate stress testing

This means they check not only whether you can afford payments today, but whether you could still afford them if interest rates increase later. Mortgage calculators can provide an early estimate, but lenders may produce different results depending on their criteria.

Step 2 — Save for a deposit

Most buyers in the UK need a deposit of at least 5% of the property value, although larger deposits usually unlock better rates.

Your deposit affects your Loan-to-Value ratio (LTV):

• lower LTV = lower lender risk
• lower risk = better mortgage deals

For many buyers, improving the deposit by even a small amount can noticeably reduce long-term borrowing costs.

Step 3 — Check your credit score

Your credit profile plays a major role in mortgage approval.
Before applying:

• review your credit report
• fix any errors
• avoid taking out new loans or credit cards

Lenders use your credit history to assess reliability and repayment behaviour. A stronger credit profile generally improves both approval chances and mortgage rates.

Step 4 — Get a Mortgage Agreement in Principle

A Mortgage Agreement in Principle (AIP) is an early indication of how much a lender may be willing to lend you. Most AIPs involve a soft credit check and can often be completed online within minutes.

An AIP is useful because it:

• helps define your budget
• shows estate agents you are a serious buyer
• speeds up the process once you find a property

It’s important to remember that an AIP is not a guaranteed mortgage offer. Full approval still depends on underwriting, affordability checks, and the property itself.

Step 5 — Compare mortgage deals

Not all mortgages are structured the same way, and the lowest rate is not always the best option overall.

When comparing deals, it’s important to look beyond the headline interest rate and consider the full cost of borrowing, including fees, flexibility, and how stable the payments will be over time. Buyers also need to choose between fixed, variable, and tracker mortgages depending on their risk tolerance and financial plans.

This is where many people use a mortgage broker. Different lenders apply different affordability rules, so comparing multiple providers can significantly improve both approval chances and available rates.

Step 6 — Submit your application

Once you’ve had an offer accepted on a property and chosen a mortgage, you can move to the full mortgage application. At this stage, the lender performs detailed checks on your finances and supporting documents. This usually includes verifying income, reviewing bank statements, checking your deposit source, and reassessing affordability in more detail than during the Agreement in Principle stage.

The application process is mainly about validation, confirming that your financial situation matches the information originally provided.

Step 7 — Property valuation & approval

After the application is submitted, the lender arranges a valuation of the property.

The purpose is to confirm that the property is worth the agreed purchase price and represents acceptable security for the mortgage. The lender also checks for issues that could affect value or saleability. If both the property assessment and underwriting checks are successful, the lender can proceed with issuing a formal mortgage offer. This is the stage where the mortgage moves from preliminary approval to a confirmed lending decision.

Step 8 – Mortgage offer & completion

If the lender is satisfied with both your financial checks and the property valuation, they will issue a formal mortgage offer. This document confirms:

• how much the lender will provide
• the mortgage term
• the interest rate
• the final conditions of the loan

Mortgage offers are typically valid for around 3–6 months, depending on the lender. After this, solicitors complete the legal work, contracts are exchanged, and the purchase is finalised on completion day.

How much can you borrow?

One of the biggest questions for buyers is: how much mortgage can I get? In the UK, many lenders offer around 4–4.5 times annual income as a general guideline. However, the final amount depends on more than salary alone.

Lenders also assess:

• monthly expenses
• existing debts
• childcare or financial commitments
• credit history
• deposit size

For example, two applicants with the same income may receive very different borrowing limits depending on their spending patterns and financial obligations. This is why affordability calculators and Agreements in Principle are useful early in the process — they provide a more realistic estimate before you begin viewing properties.

What do you need to qualify for a mortgage?

Mortgage requirements vary between lenders, but most applications are assessed around the same core areas.

• Income requirements. Lenders need to see stable and provable income. This can include salary, freelance income, bonuses, or self-employed earnings.
• Credit score. Your credit history affects both approval chances and the rates you may be offered. Missed payments, defaults, or high debt levels can reduce affordability.
• Deposit. Most buyers need at least a 5% deposit, although larger deposits usually improve mortgage terms with lower rates plus higher lending multiples.
• Employment status. Employed applicants with stable income are generally simpler to assess, while self-employed applicants may need additional documentation such as SA302 forms or company accounts.

What documents do you need?

Most mortgage advisers and lenders will ask for a similar set of documents during the mortgage application process. These usually include:

• passport or driving licence
• recent payslips
• bank statements
• proof of deposit
• address history

If you’re self-employed, they may also request HMRC Tax Calculations, HMRC Tax Year Overviews, and company accounts. Having documents prepared in advance can help avoid delays and make the process significantly smoother.

How lenders assess your affordability

Affordability is one of the most important parts of mortgage approval. Lenders don’t just look at income — they assess whether the mortgage remains manageable alongside your existing financial commitments and future rate increases. This includes reviewing:

• regular spending
• existing loans or credit cards
• childcare costs
• lifestyle expenses
• stress testing against higher interest rates

The goal is to understand not only whether you can afford the mortgage today, but whether you could still manage repayments if circumstances change.

How to improve your mortgage approval chances

If you’re planning to apply for a mortgage soon, a few practical changes can improve both your approval chances and the rates you may be offered.
The most effective steps include:

• improving your credit score
• reducing existing debt
• avoiding new loans or credit applications
• saving a larger deposit
• checking your credit report for errors

For many buyers, preparation makes a bigger difference than income alone. Small improvements in affordability or credit profile can noticeably strengthen an application.

Using a mortgage broker can also help, especially if your income is complex or you’re unsure which lenders best fit your situation.

Types of mortgages explained

Choosing the right mortgage type is just as important as getting approved.

What are the costs of getting a mortgage?

The deposit is usually the largest upfront cost, but it’s not the only expense buyers should plan for. Additional costs may include:

• solicitor fees
• property valuation
• mortgage arrangement fees
• broker fees
• stamp duty (where applicable)
• home furnishing & improvements

These expenses can add up quickly, especially for first-time buyers who focus mainly on the deposit itself. Planning for the full cost of purchasing a property helps avoid affordability issues later in the process.

How long does it take to get a mortgage?

In many cases, the mortgage approval process takes around 3 to 6 weeks, although timelines can vary depending on the lender, property, and complexity of the application. A straightforward purchase with complete documents and no valuation issues may move relatively quickly. More complex situations — such as self-employed income, chain delays, or additional lender checks — can take longer.

A typical timeline often looks like this:

Delays are usually caused by missing documents, legal issues, or problems identified during valuation.

Common mistakes to avoid when getting a mortgage

Many mortgage problems happen before the application is even submitted. One common mistake is taking new loans or credit cards shortly before applying. This can reduce affordability and negatively affect your credit profile at exactly the wrong time.

Another issue is underestimating total costs. Buyers often focus heavily on the deposit while overlooking solicitor fees, valuations, stamp duty, and moving expenses.

Small deposits can also limit mortgage options and increase borrowing costs over time. In some cases, waiting longer and improving the deposit position can lead to significantly better rates.

It’s also important to be fully transparent during the application process. Lenders will verify income, debts, and financial commitments carefully, so inconsistencies can delay or damage approval chances.
