First-time buyer mortgage eligibility

If you’re buying your first home, “eligibility” usually means more than just whether you’re a first-time buyer. Lenders assess whether they can offer you a mortgage that fits their affordability and risk criteria—based on your income, spending, deposit, credit history and the property you want to buy.

This page explains the main factors that commonly affect first-time buyer mortgage eligibility in the UK, so you can understand what to prepare before you apply.

What lenders mean by “eligibility”

When a lender decides whether you’re eligible for a mortgage, they typically consider:

• Affordability: whether your income and outgoings support the monthly repayments.
• Deposit and loan-to-value (LTV): how much you’re putting down and the size of the mortgage you’re requesting.
• Credit history: how you’ve managed credit in the past.
• Your circumstances: employment type, stability of income, and any existing financial commitments.
• The property: whether it meets lending requirements (including valuation and condition).

Even if you’re a first-time buyer, these factors can still vary significantly from person to person.

Deposit size and loan-to-value (LTV)

Your deposit is one of the most influential elements in eligibility.

• A larger deposit generally reduces the lender’s risk and may give you access to a wider range of products.
• A smaller deposit can still be possible, but it may involve stricter affordability checks and different mortgage options.

In practice, lenders often use LTV bands (for example, 90% LTV, 95% LTV, etc.). Your eligibility can depend on which band your deposit places you in.

Income, affordability and outgoings

Mortgage affordability is assessed using your income and your monthly commitments.

Lenders commonly look at:

• Your gross income (before tax)
• Regular expenses (for example, childcare, existing loans, credit cards, maintenance payments)
• How stable your income is

Affordability checks aren’t just about whether you can pay the mortgage today—they’re designed to consider whether you can sustain repayments over the term, using the lender’s own assessment approach.

Credit history and credit score

Your credit history can affect eligibility because it helps lenders understand how you manage borrowing.

Lenders may consider factors such as:

• Missed payments or defaults
• County court judgments (CCJs)
• High levels of existing debt
• Recent credit applications

A less-than-perfect credit history doesn’t automatically mean you can’t get a mortgage. However, it can influence which lenders and mortgage types are likely to be suitable.

Employment type and income stability

How you earn can matter as much as how much you earn.

Lenders may treat income differently depending on whether you are:

• Employed (often assessed using payslips and employment details)
• Self-employed (often assessed using accounts and/or tax year information)
• Contractor or freelance (often assessed based on contract patterns and evidence of income)

Eligibility can be affected by how consistent your income is and how recently it has been earned.

Existing financial commitments

If you already have other debts or financial obligations, they can reduce the amount you can borrow.

Common examples include:

• Credit cards and personal loans
• Car finance
• Student loans (where applicable)
• Maintenance payments

Even where repayments are manageable, lenders may still factor them into affordability calculations.

Property type, condition and valuation

The property you want to buy must meet lender requirements.

Lenders typically consider:

• Whether the property type is acceptable (for example, flats, houses, new builds)
• Condition and structural considerations
• Valuation (the mortgage is based on the property’s value, not just the purchase price)

If the valuation comes in lower than expected, it can affect how much you’re eligible to borrow.

First-time buyer schemes and deposit support

Some first-time buyers may explore government or developer-linked schemes, which can change the structure of the deposit and the way eligibility is assessed.

Eligibility for these schemes depends on the specific scheme rules, including property type and purchase price limits. If you’re considering a scheme, it’s important to understand how it interacts with mortgage affordability and lender criteria.

Joint applications and guarantor support

For some first-time buyers, eligibility can be improved through:

• Joint applications (combining incomes and sharing responsibility for repayments)
• Guarantor or parental support (where a third party may support the application under specific arrangements)

These options can introduce additional requirements and documentation, and they can affect how lenders assess risk.

What you can do to improve your chances of being accepted

While no one can guarantee a mortgage outcome, you can often strengthen your position by preparing key areas in advance:

• Review your credit file and address any errors
• Reduce high-interest balances where possible
• Keep spending steady in the months leading up to application
• Gather evidence of income early (especially if self-employed)
• Plan your deposit and be clear about the total funds available
• Consider the property carefully, including valuation risk
