Solo Mortgage Surge: What the UK Market Shows – A solo mortgage is not only a personal choice. It is a market signal.

More people are living alone, buying later, renting for longer and making property decisions without a second income on the application. That does not mean single buyers lack ambition. It means the mortgage market is being tested by a simple question: how does one income compete in a market built around rising prices, strict affordability rules and higher living costs?

The rise of the solo buyer should not be treated as a lifestyle trend. It is mainly an affordability story.

At a Glance

A solo mortgage is a mortgage taken by one applicant using their own income, deposit and credit profile.

The market pressure comes from three main areas:

• More single-person households across the UK
• Higher house prices compared with earnings
• Mortgage affordability checks based on one income, not two

Solo buyers may still be able to buy. However, they often need stronger deposit planning, cleaner credit conduct, careful monthly budgeting and lender criteria that fit their income type.

Why the Solo Mortgage Market Matters

The UK housing market is often discussed through couples, families and households with two incomes. That can miss a large part of the picture.

According to the Office for National Statistics, the UK had 28.6 million households in 2024, and 29.5% contained one person. More people lived alone in 2024 than in 2014. That matters because housing demand is not only created by families. It is also created by people buying alone, separating, relocating, delaying marriage, choosing independence or rebuilding after life changes.

This is where the market becomes more complex.

A couple may have two salaries, two sets of savings and more flexibility when lenders assess affordability. A solo buyer may have only one income, one credit file and one emergency fund. The property goal may be the same, but the underwriting picture is different.

That is why the solo mortgage surge is not really about confidence. It is about structure.

What the Market Data Shows

The first-time buyer market has remained important, even during periods of rate pressure.

Halifax reported that first-time buyers made up 54% of all home purchases made with a mortgage in 2024. It also reported that 341,068 first-time buyers entered the market that year, up 19% compared with 2023.

This shows that demand did not disappear. It changed shape.

Buyers became more careful. Some delayed. Some relied on larger deposits. Some bought with another person. Others explored Shared Ownership, family support or lower-priced areas. For solo buyers, these choices can be more important because there is less room for error.

The English Housing Survey also shows how affordability pressure has changed the timing of buying. In 2024-25, the average first-time buyer in England was 34. In London, the average age was 35.

That age shift tells a wider story. Many buyers are not unwilling to buy. They are waiting until the numbers work.

Why Single Applicants Face Tougher Affordability Checks

Mortgage affordability is not only based on income.

Lenders usually look at:

• Basic salary and regular income
• Overtime, bonus or commission
• Self-employed income history
• Credit commitments
• Childcare or dependant costs
• Student loans
• Car finance
• Credit card balances
• Bank statements
• Deposit size
• Property type
• Mortgage term
• Expected monthly payment

For a solo buyer, every part of this assessment sits on one person.

That can make the loan-to-income calculation tighter. It can also make existing commitments more important. A car loan, personal loan, or large credit card balance may reduce borrowing power because there is no second income to offset it.

This is why two buyers with the same deposit may receive very different outcomes. The lender is not only looking at the purchase price. It is looking at whether the mortgage is affordable now and remains credible if costs change.

The FCA has also reminded firms that lenders must consider the effect of future rate rises when assessing affordability. This is important for solo buyers because monthly payment resilience is central to the application.

A buyer can use a residential affordability calculator as an early guide. It should not replace advice, but it can help set a realistic starting point.

The Product Question: What Can Solo Buyers Consider?

There is no single “solo mortgage product” that solves affordability. Most solo buyers use standard residential mortgage products. The difference is how the case is assessed.

A solo buyer may need to consider:

Deposit size
A larger deposit can reduce the loan-to-value and may improve product choice. It can also lower the monthly payment.

Mortgage term
Some buyers choose a longer mortgage term to reduce monthly payments. This may help affordability, but it can increase the total interest paid over the life of the mortgage.

Fixed or variable rate
A fixed rate can provide payment certainty for a set period. A variable rate may change, so the buyer needs to understand payment risk.

Income type
Employed, self-employed, and contractor income, as well as bonus and commission income, can all be treated differently by lenders.

Credit profile
A clean credit file can matter more when the application depends on one person’s financial history.

Property type
Flats, new builds, leasehold properties and Shared Ownership homes may have specific lender rules.

This is where the practical side becomes philosophical. A mortgage is not only about getting accepted. It is about ensuring the commitment still feels stable upon completion.

Shared Ownership and Solo Applicants

Shared Ownership can be relevant for some solo buyers because they purchase a share of the property and pay rent on the remaining share.

This can reduce the required deposit because it is usually based on the share being purchased, not the home’s full market value.

For example, a buyer purchasing a 40% share of a property may need a deposit equal to that 40%. This can make homeownership more attainable for some single applicants.

However, Shared Ownership is not automatically cheaper in every case.

A buyer should consider:

• Mortgage payment
• Rent on the remaining share
• Service charge
• Ground rent, where applicable
• Future staircasing costs
• Lease terms
• Resale rules
• Affordability checks from the lender and housing provider

Why the Solo Buyer Journey Needs Careful Planning

A solo buyer usually needs to answer three questions before applying.

First, what deposit is realistic?

Second, what monthly payment is comfortable after bills, food, travel, insurance and savings?

Third, which lenders are likely to assess the case fairly?

The third question is often the one buyers miss.

Mortgage lenders do not all assess income in the same way. Some may be more flexible with bonus income. Some may consider certain self-employed cases more favourably. Some may be more cautious with credit commitments or property types.

That is why a decline from one lender does not always mean the buyer cannot get a mortgage. It may mean the wrong lender was approached first.

What this Means for the Mortgage Market

The surge in solo mortgages shows that demand remains, but it is more selective.

Borrowers are looking for clarity before they commit. Lenders are balancing access with risk. Advisers are helping clients understand whether the numbers work before a full application is submitted.

The market is no longer only asking, “Can this buyer get a mortgage?”

It is also asking, “Can this buyer keep the mortgage?”

That question matters most for solo applicants because there is no second income to absorb pressure if costs rise or circumstances change.

A sustainable mortgage market should not measure success only by approvals. It should measure success by outcomes that remain affordable after completion.

FAQs: Solo mortgage surge

Can I get a mortgage as a single applicant?

Yes, a single applicant can get a mortgage. The lender will assess your income, deposit, credit history, spending and the property you want to buy.

Is it harder to get a mortgage on one income?

It can be harder because affordability is based on one income. Existing debts, childcare, loans and regular spending can have a bigger effect.

How much deposit does a solo buyer need?

Some buyers may be able to buy with a smaller deposit, subject to lender criteria. A larger deposit may improve product choice and reduce monthly payments.

Can Shared Ownership help solo buyers?

Shared Ownership may help some solo buyers because the deposit is usually based on the share being purchased. Buyers must also budget for rent, service charges and other ownership costs.

Should a solo buyer speak to an adviser before viewing homes?

Yes. Speaking to an adviser early can help a buyer understand borrowing range, deposit needs, likely monthly costs and lender criteria before making offers.
