Can Overtime Income Be Used in a Mortgage Application?

Are you looking to secure a mortgage with your overtime income included? When a proportion of your total income includes overtime enhancements, it’s perfectly natural to wonder how much overtime can be used when applying for a mortgage.

Nowadays, many jobs require working different shift patterns that include weekend hours, unsociable hours, and overtime enhancements, all of which help increase a basic salary. This means that for many people, their basic annual salary alone will not truly reflect their total income that is earned each month.

The good news is that overtime income can be included in mortgage affordability calculations, helping to increase the total amount lenders will be happy to lend you. However, the challenge is that not all lenders will assess overtime income in the same way.

In this article, we walk you through how lenders assess overtime earnings, exactly what evidence will be required, the potential limitations of overtime income, and the most common issues that could affect your mortgage application. Let’s begin.

How Is Overtime Income Assessed for a Mortgage?

Overtime income can be included in a mortgage application, but lenders will want to see that any additional income is consistent and likely to continue long term. The reasons for this are pretty straightforward.

Where an annual salary remains constant and therefore easy to predict, any overtime or other payment enhancements can be subject to availability and depend on different circumstances. As a result, these types of earning can often fluctuate between months and are not always guaranteed within an employment contract.

For example, there are many occupations where overtime may be limited or unavailable for most of the year, but increase drastically during certain seasonal busy periods. In addition, any extra work that would qualify the need for overtime can depend on future staffing levels, workload, or changes within the industry itself. All of these factors can influence how lenders assess the reliability of overtime income within a mortgage application.

It’s crucial at this point to understand that not all lenders will assess mortgage applications in the same way. Instead, each lender will have their own criteria that explicitly covers affordability and how flexible they are when assessing overtime income within a mortgage application.

This will often include assessing:

• Your job title and related industry
• How frequently overtime has been completed and paid
• History or backlog of receiving overtime income
• Whether the overtime has remained reasonably consistent over time
• Conditions surrounding any employee overtime (guaranteed or voluntary)
• Whether this additional income appears sustainable long term

The structure of any overtime completed can also make a difference. For example, guaranteed overtime hours that are written into an employment contract are likely to be viewed more positively than any voluntary overtime that depends on staffing levels or demand.

As we’ve highlighted, lender policies can vary quite significantly and there is an important distinction to be made:

Lenders That Use 100% of Overtime Income: Some lenders may be willing to use 100% of overtime income within their affordability calculations, as long as the overtime is proven to be consistent over a long period and forms a reliable part of the applicant’s overall income.

Lenders That Restrict Overtime Income: Other lenders may place limits on how much overtime can be used, average the income across a set period, or potentially disregard overtime altogether if the income appears too irregular.

Because of this, finding the right lender can make all the difference when you’re planning to include overtime income in your mortgage application. Finding a lender that accepts overtime earnings may result in a much higher borrowing amount compared to a lender with a stricter affordability criteria.

What Evidence Is Required by Mortgage Lenders?

Supporting documents are often required in a mortgage application to provide evidence of how much overtime you earn, how frequently it is paid, and whether this type of income has remained consistent over a period of time. Together, this helps give lenders a much clearer picture of your overall earnings and can help strengthen your mortgage application.

As a general rule, the easier it is for lenders to assess your total income, the more realistic they can be with including overtime in your affordability calculations.

There are several different documents that can help evidence your total income, with overtime income for mortgage applications usually being assessed across multiple documents rather than one specific document alone. For example, payslips can help show what you have been earning recently, while bank statements and tax documents can provide lenders with insights into payments that have been received over time.

To help you understand the different types of documents that lenders can request, we have created a quick guide to the most common lender requests when assessing overtime income for a mortgage:

It’s crucial that you’re completely honest in your mortgage application. Any missing documents, unexplained income fluctuations, or inconsistent payments between payslips and bank statements can all raise additional questions with lenders and lead to unnecessary delays.

In cases where overtime earnings have increased significantly in recent months, lenders may choose to ask for further clarification. These extra overtime income documentation requirements can be specific to your lender and are usually about understanding whether the higher earnings are likely to continue in the long term.

How Do Mortgage Lenders Check Overtime Income?

To lenders, it’s not about getting a one-off big paycheque as proof of your income. Instead, they’re looking for reliability in the form of consistent income that can be managed long-term. As a result, lenders will not only be looking at how much overtime you earned this month, but evaluating how the income is likely to continue after the mortgage completes.

This is why consistent overtime income is often more important than an occasional large payslip. Providing evidence of a steady pattern over several months will typically carry more weight in your mortgage application than short bursts of unusually high income.

In addition, lenders will examine the wider patterns of your employment. They may look at how long you have been with your current employer, whether overtime appears throughout the year, and whether the working pattern seems realistic over the long term.

For example, those who work consistent shift patterns within the healthcare, emergency services, or other overtime-heavy industries, would generally be viewed more positively because there is an ongoing demand for additional staffing and overtime hours throughout the year.

On the other hand, in cases where income appears unpredictable or heavily dependent on short-term circumstances, lenders may limit the amount of overtime that they would be willing to include in their affordability calculations.

Ultimately, regular overtime patterns in affordability checks are largely about a lender’s risk management. Mortgage lenders need to feel comfortable that repayments would remain affordable if the overtime income was reduced in the future.

How Much Overtime Income Will Mortgage Lenders Use?

There is no fixed percentage of overtime income that mortgage lenders will use, as each lender will have their own affordability policy and lending criteria. In practice, many high street lenders may use anything from 50% of your overtime earnings through to the full amount, depending on your circumstances and the strength of the supporting evidence.

As a result, the answer to “How much overtime will count towards my mortgage affordability?” is that the total percentage of overtime income that can be used could vary quite significantly depending on your lender.

To help demonstrate how much overtime income different lenders may be willing to use, we’ve provided a general overview of some common lender criteria below:

As the table demonstrates, the lending criteria can vary quite significantly when it comes to assessing overtime income within a mortgage application. That’s why working with a lender that caters to your specific income structure and allows overtime to form part of your regular earnings can make a substantial difference to both your total affordability and borrowing potential.

What Are the Problems Using Overtime for a Mortgage Application?

One of the biggest overtime income mortgage application mistakes is assuming that all overtime earnings will automatically be included in your affordability calculations. As we’ve just explored, lenders have their own criteria and policies that surround accepting different types of income in their calculations.

Additionally, all lenders that do accept overtime income in their affordability calculations will generally request to see evidence that any overtime income has been received consistently over time and forms a reliable part of your overall earnings.

As such, problems can often arise when this income starts to appear irregularly or without clear evidence that allows lenders to identify a clear picture of your income reliability. For example, any large fluctuations between payslips, missing supporting documents, or an application that relies on a short burst of increased income will usually create issues during a mortgage application.

To help you avoid any unnecessary delays or affordability issues, here are some of the most common mistakes people make when using overtime income for a mortgage application:

• Assuming all overtime income will automatically count towards affordability
• Applying for a mortgage before overtime patterns have become consistent
• Relying on a short period of unusually high overtime earnings
• Submitting incomplete payslips or missing supporting documents
• Choosing a lender without checking how they assess overtime income
• Relying too heavily on temporary or seasonal overtime

A key point to note is that many of the reasons overtime income may be rejected by lenders ultimately comes down to reliability rather than the income amount itself. Taking the time to prepare the right documents carefully, understanding your chosen lender’s criteria, and applying at the right time can all help improve the strength of your application.
