Why Spending Habits Matter in a Mortgage Application

Affordability is not just about income—it’s about how much disposable income remains after your regular spending. Lenders want to ensure that:

• Your financial behaviour is stable
• Mortgage payments are sustainably manageable
• You are not over-committed financially
• There is a clear pattern of responsible spending

This helps lenders determine whether your monthly expenditure leaves enough room for mortgage repayments, even during interest rate rises.

What Lenders Review When Looking at Spending Habits

Lenders typically check the last 3–6 months of bank statements. The aim is to gain an accurate and up-to-date picture of your financial behaviour.

Lenders look for:

1. Essential Monthly Spending

These include:

• Rent
• Utilities
• Council tax
• Food and groceries
• Transport and fuel
• Insurance
• Phone and broadband

These are known as fixed or essential costs, and lenders use them to calculate affordability.

---

2. Discretionary Spending

These are non-essential expenses such as:

• Eating out
• Entertainment
• Subscriptions
• Holidays
• Retail shopping
• Lifestyle purchases

Moderate discretionary spending is completely normal, but consistently high non-essential spending may reduce borrowing capacity.

---

3. Regular Financial Commitments

These include:

• Car finance
• Personal loans
• Credit cards (minimum payments)
• Overdraft usage
• Store cards
• Buy-now-pay-later plans
• Childcare costs
• Gym memberships

Lenders treat these as ongoing commitments and deduct them from affordability.

---

4. Gambling Transactions

Occasional, low-value gambling is usually not an issue.
However, lenders may take a cautious approach if they see:

• High-frequency gambling
• Large transactions
• Persistent patterns

They want to ensure the spending is manageable and not financially risky.

---

5. Overdraft Behaviour

Using an overdraft occasionally is common, but lenders may be concerned if:

• You are regularly in your overdraft
• You exceed your overdraft limit
• Your balance is frequently close to zero

This suggests limited financial buffers.

---

6. Payday Loans or Short-Term Credit

Recent payday loan use is a red flag for many lenders.
It suggests short-term financial difficulties, even if the loan is repaid on time.

---

7. Subscription Services

Lenders increasingly review spending on:

• Streaming services
• Fitness apps
• Monthly boxes
• Premium accounts

Individually they are small, but in total they may influence affordability.

---

How Lenders Categorise Spending: The Three Pillars

Most mortgage lenders use three broad spending categories:

---

1. Fixed Essential Costs

Costs that are necessary and consistent each month.
Lenders treat these as non-negotiable.

2. Credit Commitments

Any form of borrowing or recurring financial obligation.
These reduce disposable income directly.

3. Discretionary/Lifestyle Spending

More flexible spending patterns that show financial behaviour.
Excessive spending in this area may reduce affordability.

---

What Spending Lenders Don’t Usually Worry About

While they review a full picture of your spending, some things are rarely concerning:

• One-off purchases (e.g., a holiday, a laptop)
• Occasional large bills
• Seasonal spending spikes
• Shared bills that stop at completion (with documentation)

Lenders focus on patterns, not isolated transactions.

---

How Cash Withdrawals Are Viewed

Frequent or large cash withdrawals may lead lenders to ask for clarification because:

• They cannot easily categorise the spending
• It may indicate untracked commitments

Occasional cash use is fine, but consistent high withdrawals may require explanation.

---

Joint Applications and Spending Habits

In joint applications, lenders assess the combined expenditure of both applicants. They review:

• Separate bank statements
• Joint spending habits
• Individual commitments
• Shared expenses

Even if one applicant has strong financial behaviour, excessive spending by the other can still affect affordability.

---

Do Lenders Compare Your Spending With National Standards?

Yes. Lenders typically use Office for National Statistics (ONS) data or their own internal models to estimate reasonable spending levels for:

• Household size
• Location
• Dependants
• Lifestyle indicators

If your spending is significantly above typical ranges, lenders may question affordability.

---

Common First-Time Buyer Concerns About Spending

1. “Do I need to stop spending entirely?”

No. Normal, sensible spending is fine.

2. “Will they decline me for a few large purchases?”

Unlikely. Lenders look at patterns, not single events.

3. “What if I have a gym membership or subscriptions?”

These are acceptable. Lenders simply factor them into affordability.

4. “Do I need to explain everything?”

Only unusual or very high expenditure may require explanation.

How Spending Habits Affect Borrowing Amounts

High discretionary spending or multiple commitments can reduce:

• Maximum borrowing
• The lender’s income multiple
• Affordability modelling
• Overall financial stability indicators

Even small recurring payments can add up and influence the final borrowing limit.

---

Are Lenders Becoming Stricter on Spending?

In recent years, lenders have strengthened affordability assessments due to:

• Economic changes
• Cost-of-living increases
• More regulatory focus on sustainable lending

This means spending behaviour carries more weight than before.

---

What If Your Spending Recently Changed?

Lenders look at recent behaviour.
If your spending patterns have changed — for example, reducing expenses — they may:

• Acknowledge improved behaviour
• Request additional bank statements
• Seek explanations for previous patterns

Documentation helps show that new patterns are sustainable.
