Does Having Children Affect a Mortgage

How Having Children Impacts Your Mortgage Application

You’ve built a family, and now you’re thinking about your next big step, buying a home. But with children in the picture, you might be wondering, does having children affect a mortgage application?

The short answer is yes, it can. But that doesn’t mean getting a mortgage with children is impossible or even harder in some occasions. It simply means lenders will take a closer look at your finances, including your income, outgoings, and how your dependents fit into the picture.

Why Having Children Can Affect Your Mortgage Application

Having children is one of life’s most rewarding experiences, but it’s no secret that they come with financial responsibilities.

Mortgage lenders assess whether you can comfortably afford monthly repayments, and part of that involves looking at your outgoings.

Children bring additional costs, such as childcare, food, clothing, education, and other day-to-day expenses. These are factored into a lender’s affordability assessment.

While children are not seen as a “negative” in your application, they do represent a financial commitment. That’s why lenders will typically ask whether you have dependents and how many, and they’ll use this information alongside your income and expenses to determine how much they’re willing to lend you.

Understanding Affordability Assessments

In the past, lenders relied mainly on income multiples, typically 3 to 5 times your salary, to decide how much you could borrow. Today, things are more nuanced.

Affordability assessments now consider your total financial picture, income, debts, spending habits, and yes, your children.

If you’re applying for a mortgage with dependents, the key areas lenders assess include:

  • The number of children you have
  • Your monthly childcare or school-related costs
  • Whether you’re receiving child benefit or tax credits
  • Changes to your working hours due to parenting
  • How much disposable income you have after expenses

Each lender has their own criteria, and that’s where tailored advice from Kerr & Watson will help.

How Children Affect Mortgage Borrowing Limits (Income Multiples vs Affordability)

While income multiples are often mentioned (such as 3–5x salary), modern mortgage decisions rely heavily on affordability modelling.

This means two families earning the same income may be offered different loan amounts depending on:

  • Number of dependants
  • Age of children
  • Ongoing childcare costs
  • Existing financial commitments

For example, a household earning £60,000 with no children may be offered more than a household earning £60,000 with two children in full-time childcare.

This is because lenders assess real disposable income, not just gross salary.

Understanding which lenders apply stricter stress testing, and which take a more flexible view, can significantly affect how much you’re able to borrow.

How Age of Children Can Influence Affordability

Not all dependants are treated the same way in affordability models. Lenders may assess differently depending on whether your children are:

  • In full-time nursery
  • At primary or secondary school
  • In further education
  • Financially independent adults

Younger children typically mean higher childcare costs, while older children may result in reduced or no childcare expenses.

If childcare costs are due to end within the next 6–12 months, some lenders may take this into account when assessing affordability, but this varies by lender.

This is why timing can sometimes make a difference when applying for a mortgage.

How Childcare Costs Impact Mortgage Applications

Childcare can be one of the largest expenses for parents, especially during the early years. Whether you’re paying for nursery, after-school clubs, or full-time childcare, these costs are considered part of your regular outgoings.

Lenders typically request a breakdown of these costs, especially if they significantly reduce your disposable income. The higher your monthly childcare bill, the lower the mortgage amount you may be offered.

However, not all lenders treat childcare costs in the same way. Some may discount them entirely if they’re set to end soon, for example, if your child starts school in September.

Others may take a more generous approach if grandparents provide care.

Future Planning: Expanding Your Family

If you are planning to have more children, lenders generally assess affordability based on your current circumstances not, future plans. However, from a financial planning perspective, it’s important to consider:

  • Whether your income may reduce temporarily
  • Whether childcare costs may increase
  • How this could affect future remortgaging

Taking advice before committing to a mortgage can help ensure your repayments remain comfortable even if your family grows.

Income Changes: Maternity Leave and Returning to Work

If you’re currently on maternity or paternity leave, or planning to go on leave soon, this can impact your mortgage application.

Some lenders may only take your reduced leave income into account, while others are willing to consider your full return-to-work salary if you can provide evidence.

This usually involves:

  • A letter from your employer confirming your return date
  • Confirmation of your post-leave income and working hours
  • Proof of savings to cover repayments during your leave

If you’re planning to return to work part-time, this may lower your overall income, and in turn, affect the loan amount you can access.

What About Self-Employed Parents?

Self-employed parents often face a few extra hurdles when applying for a mortgage, especially if their income has fluctuated due to maternity or paternity leave.

Most lenders will want to see at least two years’ worth of trading accounts or tax returns, but there are exceptions.

You may need to provide:

  • SA302s and tax year overviews
  • An accountant’s reference
  • Evidence that your business can sustain itself while you take time off

Some lenders are more understanding of temporary drops in income, especially when there’s a clear plan to return to normal operations.

Kerr & Watson has experience in placing self-employed applicants with the right lenders, so don’t let this put you off finding out your options.

Child Benefit and Tax Credits

Many parents receive child benefit, working tax credit, or child tax credit, and you may be wondering if these can be counted as income.

In many cases, yes they can. Some lenders will include a portion (or all) of these benefits as part of your overall income, which could boost your borrowing capacity.

It’s worth noting, though, that there are often limits on how much of this income lenders will consider, and some lenders don’t include it at all. This is where personalised advice is important.

Why Lender Criteria Matters for Families

Every lender uses different affordability software and assumptions.

Some:

  • Apply stricter household expenditure models
  • Assume higher living costs per dependant
  • Exclude certain benefit income

Others:

  • Take a more flexible approach
  • Consider confirmed return-to-work income
  • Accept child benefit as income

Choosing the right lender for your family’s circumstances can make a meaningful difference to what you’re offered. This is where specialist advice becomes valuable.

Other Factors to Consider

Lenders may also take into account the following:

  • School Fees: Some lenders discount or ignore private school fees, while others factor them in heavily.
  • Childcare Vouchers: These might be ignored by some lenders when calculating net income.
  • University-aged Children: If your children are financially independent, lenders may not include them as dependents in the affordability check.
  • Living Arrangements: If you’re moving closer to your child’s school, your commuting and childcare costs could decrease, which might improve your affordability.

Trying to work it all out on your own can be overwhelming. That’s why working with a trusted mortgage broker like Kerr & Watson can make all the difference.

How You Can Improve Your Chances of Mortgage Approval

Having children doesn’t have to stand in the way of buying your ideal home. Here are some practical steps to help your mortgage application:

  • Provide clear, up-to-date records of your income and outgoings
  • Ensure your credit score is in good shape
  • Be transparent about any benefits or tax credits you receive
  • Speak to your employer about a return-to-work letter, if applicable
  • Work with an experienced mortgage broker who understands your needs

We take the time to understand your personal and family circumstances and match you with lenders who are suited to your situation.

Protection Considerations for Families

When you have children, mortgage protection becomes even more important.

Lenders don’t require you to take protection policies (although some will discuss it), but as a family, you may want to consider:

If one income supports the household, protecting that income is crucial.

As part of our advice process, we also look at how to safeguard your family’s home, not just secure the mortgage.
