20 July 2026

Many buyers wrongly assume that a small deposit, poor credit or self-employed income automatically rules them out of getting a mortgage. Different lenders assess applications in different ways, so speaking to a mortgage adviser early can help buyers understand their options and avoid unnecessary applications.

Buying a home is one of the biggest financial decisions you'll ever make, so it's understandable that you'll want to get things right. Unfortunately, it's also a process surrounded by plenty of advice, and not all of it is accurate.

Many people delay buying a home because they've heard they need a huge deposit, believe their credit history will automatically prevent them from getting a mortgage, or assume being self-employed means they won't qualify. These are some of the most common mortgage myths that continue to discourage buyers from exploring their options.

Every lender has different criteria, and mortgage products continue to evolve. A lender that declines one application may be accepted by another.

In this article, we'll look at some of the most common mortgage myths UK buyers still believe, explain what's fact and what's fiction, and help you understand why speaking to a mortgage adviser before ruling yourself out could make all the difference.

Myth 1: You Need a 20% Deposit to Buy a Home

One of the biggest mortgage myths is that you need to save a 20% deposit before you can even think about buying a property.

While a larger deposit can sometimes provide access to a wider range of mortgage products or more competitive interest rates, it isn't always a requirement.

Many lenders offer mortgages with much smaller deposits, although eligibility will depend on your individual circumstances and the lender's criteria.

If you're wondering how much deposit you need for a mortgage, the answer isn't the same for everyone. Factors such as your income, the property you're buying and the mortgage product you're applying for can all influence the deposit required.

For many first-time buyers, waiting until they've saved a large deposit could delay home ownership unnecessarily. Exploring your options earlier may help you understand what's realistically achievable.

Myth 2: Bad Credit Means You Can't Get a Mortgage

It's easy to assume that a poor credit history automatically means your mortgage application will be declined.

In reality, it's rarely that straightforward.

Different lenders assess credit history in different ways. Some may be willing to consider applicants who have experienced financial difficulties in the past, while others may apply stricter lending criteria.

The type of credit issue, how long ago it occurred, and your current financial circumstances can all influence the outcome of a mortgage application.

If you're worried about applying for a mortgage with poor credit, speaking to a mortgage adviser before submitting an application may help you understand which lenders could be suitable for your circumstances.

That can also reduce the risk of making unnecessary applications that may be declined.

Myth 3: Self-Employed People Can't Get a Mortgage

This is another common misconception.

Being self-employed doesn't automatically prevent you from getting a mortgage. However, the way lenders assess your income may differ from someone who is employed.

Whether you're a sole trader, freelancer, contractor or limited company director, lenders will usually want to understand how your business performs and whether your income is sustainable.

The documents required can vary depending on the lender and your circumstances, which is why many self-employed applicants benefit from seeking advice before applying.

Applying for a self-employed mortgage is often less about your employment status and more about providing the information a lender needs to assess your application.

Myth 4: You Need a Perfect Credit Score to Get a Mortgage

Many buyers worry that they need a flawless credit score before applying.

The reality is that lenders don't all assess applications in exactly the same way.

While your credit history forms an important part of the decision-making process, lenders also consider factors such as your income, existing financial commitments, deposit and overall affordability.

Different lenders use different lending criteria, so there isn't one universal credit score for a mortgage that guarantees approval or rejection.

If you're unsure where you stand, reviewing your credit report before applying and discussing your circumstances with a mortgage adviser can help you understand the options available.

Myth 5: Your Bank Will Always Offer the Best Mortgage

Many buyers naturally approach their own bank first when looking for a mortgage.

While this can sometimes be the right solution, it isn't always the only option available.

Every lender has its own mortgage products, lending criteria and affordability assessments. That means another lender may offer a product that's better suited to your individual circumstances.

This can be particularly relevant if your income is more complex, you're buying your first home, or your circumstances don't fit standard lending criteria.

Comparing a wider range of mortgage options may help you identify products that you wouldn't necessarily find by approaching a single lender.

Why Speaking to a Mortgage Adviser Can Help

One of the biggest reasons these mortgage application myths continue to circulate is that many people assume every lender works in exactly the same way.

In reality, lenders can take very different approaches when assessing affordability, income and credit history.

Speaking to a mortgage adviser before applying can help you understand your options, identify mortgage products that may be suitable for your circumstances and avoid making unnecessary applications.

Whether you're buying your first home, moving property or have more complex financial circumstances, receiving tailored advice early in the process can help you move forward with greater confidence.
