First-Time Buyer Mortgage Guide UK

First-Time Buyer Mortgage Guide UK:  Buying your first home is not just about finding a property.

It is about proving that the mortgage, the deposit, the property and the future monthly payments all fit together.

A first-time buyer mortgage is usually a residential mortgage for someone buying their first home. Lenders will look at your income, deposit, credit history, outgoings, debts, property type and loan-to-value before deciding whether to lend.

Connect Lifetime helps first-time buyers understand these steps clearly before they apply. That matters because a mortgage application is not only a form. It is evidence of financial readiness.

At a Glance

A first-time buyer can often apply for a mortgage with a deposit from 5%, subject to lender criteria.

Lenders assess income, spending, debts, credit history and the property.

A mortgage in principle can help before making an offer.

Your deposit source must be clear, especially if family are helping.

First-time buyer Stamp Duty relief may apply in England and Northern Ireland.

Extra costs can include legal fees, surveys, valuation fees, moving costs and insurance.

A mortgage adviser can help compare lender criteria and prepare the application.

Your home may be repossessed if you do not keep up repayments on your mortgage.

What is a first-time buyer mortgage?

A first-time buyer mortgage is a mortgage used to buy your first home.

It is usually a residential mortgage. This means the property will be your main home, not a rental property or business premises.

Most first-time buyers repay the mortgage monthly over an agreed term. The mortgage is secured against the property. If payments are not maintained, the lender can take action.

This is why the decision needs care. The right mortgage is not only the one with a competitive rate. It must also fit your income, deposit, property plans and future affordability.

How much deposit does a first-time buyer need?

Many first-time buyers start with a deposit of at least 5%.

For example, if a property costs £250,000, a 5% deposit would be £12,500. The mortgage would cover the remaining £237,500, subject to lender approval.

This would usually be called a 95% loan-to-value mortgage.

A larger deposit may help reduce lender risk. It may also give access to more mortgage products. However, the right deposit size depends on savings, affordability and the property being bought.

Common examples:

A deposit is only one part of the cost. First-time buyers also need to budget for legal work, valuation, survey costs, moving costs and possible Stamp Duty.

How lenders assess first-time buyers

Lenders do not only ask how much you earn.

They also check how stable and sustainable your finances look.

They may assess:

• Income.
• Employment type.
• Length of time in your job.
• Self-employed income history.
• Overtime, bonuses or commission.
• Bank statements.
• Credit commitments.
• Student loans.
• Childcare costs.
• Dependants.
• Credit history.
• Deposit source.
• Property type.
• Loan-to-value.
• Mortgage term.

Two buyers with similar income may receive different outcomes from different lenders. This is because lenders use their own affordability models and risk rules.

Mortgage in Principle: Why it helps

A mortgage in principle gives an early indication of what a lender may be willing to consider.

It is not a formal mortgage offer. It does not guarantee approval. However, it can help you understand your price range before viewing properties or making an offer.

Estate agents may also ask whether you have one. It can show that you have started the financial checks.

Before requesting a mortgage in principle, check your credit file, deposit evidence and income documents. A cleaner application can reduce delays later.

Credit Checks and First-Time Buyers

Your credit file helps lenders understand how you manage borrowing.

A missed payment does not always stop a mortgage application. However, it can affect lender choice, rate options and the evidence needed.

Before applying, check:

• Your name and address history.
• Electoral roll registration.
• Credit card balances.
• Loan payments.
• Missed or late payments.
• Defaults or county court judgments.
• Financial links to other people.
• Unused credit accounts.

Do not guess what your credit file says. Review it early and speak to an adviser before making major changes.

First-time buyer mortgage if you are self-employed

Self-employed first-time buyers can get mortgages.

However, the evidence can be different from employed applicants. Lenders may ask for accounts, tax calculations, tax year overviews, business bank statements or company accounts.

They may also look at income stability. A sole trader, contractor, limited company director or freelancer may all be assessed differently.

This is where advice can help. One lender may use the latest year’s income. Another may average income over two years. Some may take a more detailed view of retained profit, dividends or contract income.

Gifted deposits and family support

Many first-time buyers receive help from family.

A gifted deposit can be accepted by many lenders, but it must be declared. The lender usually needs to know whether the money is a gift or a loan.

This matters because a repayable loan can affect affordability.

A lender may ask for:

• A gifted deposit letter.
• Proof of funds.
• Bank statements.
• Identification from the donor.
• Confirmation that the donor will not own part of the property.

Family support can be helpful, but it must be documented properly.

Lifetime ISA and first-time buyers

A Lifetime ISA can be used to buy a first home or save for later life. GOV.UK says you can put in up to £4,000 each year, with a 25% government bonus up to £1,000 per year.

For a first home purchase, GOV.UK guidance says the property price must be £450,000 or less, the buyer must intend to live in the property as their main residence, and at least 12 months must have passed since the first Lifetime ISA payment.

This means timing matters. First-time buyers should speak to their conveyancer and adviser before withdrawing Lifetime ISA funds.

Read the official GOV.UK Lifetime ISA guidance before relying on the account for your deposit.

Stamp Duty for first-time buyers

Stamp Duty Land Tax applies in England and Northern Ireland when buying property or land over certain thresholds.

For first-time buyers, GOV.UK states that SDLT starts to apply at £300,000 when buying a residential property worth £500,000 or less.

The rules are different in Scotland and Wales. Scotland uses Land and Buildings Transaction Tax. Wales uses Land Transaction Tax.

You can review the official GOV.UK Stamp Duty Land Tax guidance or estimate your position with Connect Lifetime’s Stamp Duty calculator.

Other first-time buyer costs to plan for

The mortgage is only one cost.

You may also need to budget for:

• Conveyancing fees.
• Search fees.
• Survey costs.
• Valuation fees.
• Mortgage product fees.
• Broker fees, where applicable.
• Removal costs.
• Buildings insurance.
• Contents insurance.
• Initial repairs.
• Furniture and appliances.
• Service charges, if leasehold.

This is where many first-time buyers underestimate the process. A home purchase can fail if the deposit is saved but the wider budget is too tight.

A good mortgage plan should include both upfront costs and future monthly costs.

Fixed, tracker and variable mortgage rates

First-time buyers may be offered different types of mortgage rates.

A fixed rate keeps the interest rate the same for an agreed period. This can help with budgeting because monthly payments are predictable.

A tracker rate usually follows a reference rate, such as the Bank of England base rate. Payments can rise or fall.

A variable rate can change according to the lender’s terms.

The right choice depends on your budget, risk tolerance and plans for the property. A lower starting rate is not always the safest option if payments could rise beyond your comfort level.

Protection and insurance conversations

Buying a first home creates a long-term financial commitment.

This is why protection should be discussed alongside mortgage advice. The aim is not to add unnecessary products. The aim is to consider what would happen if illness, injury, death or loss of income affected the household.

First-time buyers may need to discuss:

• Life insurance.
• Critical illness cover.
• Income protection.
• Buildings insurance.
• Contents insurance.
• Family protection needs.

Buildings insurance is usually required by the lender from exchange of contracts. Other protection products depend on personal needs and affordability.

Common first-time buyer mistakes

First-time buyers often focus on the property before the mortgage.

That can create problems. A property may look affordable online but fail lender affordability checks.

Common mistakes include:

• Viewing homes before checking affordability.
• Ignoring credit file issues.
• Forgetting legal and survey costs.
• Using borrowed deposit funds without disclosure.
• Applying to the wrong lender.
• Changing jobs during the process.
• Taking new credit before completion.
• Underestimating monthly bills after moving in.
• Forgetting protection and insurance needs.

The better approach is simple. Prepare first. View second. Apply when the evidence is ready.
