Can You Get a Mortgage on One Income? Single Person Mortgages Explained

Applying for a mortgage on your own can feel like a big step, especially when lenders seem to focus heavily on affordability. But getting a mortgage on one income is completely achievable — and far more common than many people think.

Every month, we help single applicants secure mortgages, including those with variable income, credit challenges, or previous declines. This guide explains exactly what lenders look for, how much you may be able to borrow, and what you can do to strengthen your application.

Let’s break it down clearly.

Can You Get a Mortgage on One Income?

Yes — you can absolutely get a mortgage on one income.

Lenders assess your affordability based on your income, your credit profile, and your outgoings, not whether you’re applying alone. As long as your finances show you can comfortably manage the monthly repayments, there are plenty of lenders who would consider your application.

Being a single applicant simply means:

• Borrowing potential is based on one salary
• Affordability needs to be clear and well presented
• Some lenders may be more suitable than others

If your situation is more complex — such as self-employment, commission-based income or past credit issues — this is where specialist guidance becomes particularly helpful.

We’re here to help if you’d like to talk through your options.

How Much Can You Borrow on One Income?

Most lenders use an income multiple of 4 to 4.5 times your annual salary, although some may offer slightly more depending on your profession and overall affordability.

Here’s what that could look like:

• Salary of £30,000 → £120,000 – £135,000
• Salary of £40,000 → £160,000 – £180,000
• Salary of £50,000 → £200,000 – £225,000

Your borrowing capacity may increase if:

• You receive regular overtime or commission
• You have a strong credit profile
• You have minimal debts or outgoings
• Your deposit is higher than average

If your income includes bonuses, freelance work, or self-employed profits, lenders often average this over 3–12 months — sometimes longer.

We can run a lender-specific affordability check for you to give you clearer numbers.

What Do Lenders Look At When You Apply Alone?

When you’re applying for a mortgage on your own, lenders focus on four main areas:

1. Your income

Lenders will consider different types of income, including:

• Salary
• Overtime
• Bonuses and commission
• Self-employed trading profits
• Dividends
• Certain benefits (varies by lender)
• Pension income

If your income varies month to month, lenders will usually average it.

2. Your monthly outgoings

Affordability takes into account:

• Credit commitments
• Car finance
• Loans
• Credit card balances
• Childcare costs
• Bill payments
• Regular spending shown on bank statements

Our guide on what lenders look for on bank statements explains this in more detail.

3. Your credit history

A strong credit profile can improve your borrowing options, but you don’t need a perfect score to be approved.

We help many single applicants secure mortgages despite:

• Late payments
• Defaults
• CCJs
• Arrangements
• DMPs
• Past bankruptcy

For these situations, see our guides on DMP mortgages or mortgages after bankruptcy.

4. Your deposit

The larger your deposit, the lower the risk to the lender — and the better your rate choices.

How Much Deposit Do You Need for a Single Person Mortgage?

Deposit requirements vary depending on your credit profile:

• 5% deposit – for applicants with strong credit
• 10% deposit – for applicants with minor issues or irregular income
• 15–25% deposit – for adverse credit (defaults, CCJs, DMPs, etc.)

For new-build homes, some lenders require a minimum deposit of 10–15%.

If you’re remortgaging, your equity takes the place of your deposit.

---

Is It Harder to Get a Mortgage on One Income?

Not harder — just more focused.

The main consideration is that affordability must fit comfortably within one person’s budget. Because lenders base their decision on income vs. spending, single applicants need clear financial stability.

Areas where single applicants sometimes face challenges include:

• High levels of unsecured debt
• Significant childcare costs
• Variable income
• Tight affordability margins
• Recent credit issues

But none of these automatically mean a decline — it’s about matching you with the right lender.

---

Can You Get a Mortgage on One Income With Bad Credit?

Yes — it’s possible, and we help people do this every week.

Lenders will consider:

• When the issue occurred
• How severe the issue was
• Whether it has been resolved
• How stable your finances are now
• How strong your deposit is

Typical deposit expectations for adverse credit:

• 10% for older or minor issues
• 15–25% for recent or significant issues

If this applies to you, our specialist guides on bad credit and DMP mortgages go into more detail.

---

Can Single Parents Get a Mortgage?

Yes — many lenders accept:

• Child maintenance
• Universal Credit
• Child Benefit
• Working Tax Credit
• Disability benefits (depending on type)

Not every lender includes these income types, but we work with those who do. This can significantly increase the borrowing capacity for single parents.

---

Can You Get a Mortgage on One Income If You’re Self-Employed?

Yes — being self-employed does not stop you from getting a single person mortgage.

Lenders may ask for:

• 1–3 years of accounts
• SA302s and tax year overviews
• Business bank statements
• Evidence of company profits (for directors)

Some specialist lenders accept just one year of trading, depending on your case.

If your income is a mix of salary, dividends, or retained profits, we’ll help ensure lenders consider your full earnings.

What Mortgage Term Should a Single Applicant Choose?

Choosing your mortgage term impacts affordability.

Shorter terms (e.g., 15–20 years)

Pros:

• Lower total interest
• Mortgage finishes sooner
  Cons:
• Higher monthly repayments

Longer terms (25–35 years)

Pros:

• Lower monthly repayments
• Easier affordability
  Cons:
• Higher total interest paid

Many lenders allow 10% annual overpayments, helping single applicants shorten the term without committing upfront.

---

What If Your Bank Has Declined You?

This is very common — and rarely the end of the road.

Reasons banks decline single applicants include:

• Non-standard income
• Overtime/commission reliance
• Contract work
• Adverse credit
• High outgoings
• Recent job changes
• Tight affordability margins

Specialist lenders often use different criteria and can be far more understanding.

We help many applicants who were declined by their bank but approved elsewhere.
