Mortgage deals for first time buyers are not one single product. They usually include fixed-rate, tracker and variable-rate mortgages, plus some lender-specific first-time buyer options such as cashback, low-deposit products or family-supported routes.

The best first-time buyer mortgage is not simply the one with the lowest headline interest rate. It is the deal you can afford, understand and qualify for, after taking account of the deposit, income, credit history, property type, fees, incentives and your plans over the next few years.

This guide is general information only and is not personal mortgage advice. Your options depend on your circumstances, lender criteria and the property you want to buy.

Plain English: a good first-time buyer mortgage deal should answer three questions: Can I qualify for it? Can I afford it comfortably? And is it still good value after fees, risks and future plans are considered?

What does a first-time buyer mortgage deal mean in practice?

A first-time buyer mortgage deal is usually a residential mortgage product available to someone buying their first home. The deal may vary by:

• interest rate;
• fixed, tracker or variable structure;
• deposit size and loan-to-value;
• product fee;
• mortgage term;
• cashback or other incentives;
• early repayment charges;
• lender criteria;
• property type.

A lender may advertise a first-time buyer mortgage, but that does not mean every first-time buyer will qualify. Lenders usually assess your income, regular commitments, credit history, deposit source, property and whether the mortgage appears affordable now and in future.

public guidance explains that buyers should compare mortgages carefully and consider whether to get advice. GOV.UK also highlights that buying a home involves costs beyond the deposit, such as surveys, legal fees, searches and moving costs.

What mortgage is best for a first-time buyer?

There is no single best mortgage for every first-time buyer. The right deal depends on the trade-off between certainty, cost, flexibility and lender fit.

For many first-time buyers, a fixed rate is attractive because it makes budgeting easier when moving into a first home. That does not mean a fixed rate is always best. If you expect to move soon, repay a lump sum or need flexibility, early repayment charges and portability may matter as much as the rate.

James Blackler at The Mortgage Blog often recommends first-time buyers compare deals in this order: lender fit first, affordability second, total cost third, then headline rate. If a lender is unlikely to accept your income, deposit source or property type, the advertised rate is not useful.

How do you compare first-time buyer mortgage deals properly?

Do not compare deals by rate alone. A lower rate with a high product fee may cost more than a higher-rate deal with no fee, especially on a smaller mortgage.

Use this checklist before deciding a deal is genuinely competitive:

A practical way to compare two deals is to ask: What will this cost me over the period I expect to keep it, including fees? A mortgage adviser can help compare the overall cost rather than only the initial monthly payment.

Example scenario: the lowest rate is not always the safest first application

A first-time buyer finds a flat at the top end of their budget and compares two mortgage deals online. One has a lower headline rate but a product fee. Another has a slightly higher rate, no product fee and a small cashback incentive. On the surface, the lower-rate option looks like the obvious winner.

The details make it less straightforward. Part of the deposit is coming from a parent, the buyer has a small car finance payment, and the flat has a service charge and ground rent. The lender with the lower headline rate may be less suitable if it takes a stricter view on commitments, wants clearer gifted deposit evidence, or assesses the service charge more heavily in affordability. If the product fee is added to the loan, the true cost over the initial deal period may also be closer than the rate comparison suggests.

A broker would usually want to check:

• whether the deposit is savings, a gift or a repayable loan;
• how the car finance and any credit cards affect affordability;
• whether the lender is comfortable with the flat, lease terms and service charge;
• whether the product fee makes sense for the mortgage size;
• whether cashback is useful, but not distracting from the overall cost;
• whether the buyer may move or remortgage before any early repayment charge ends.

The lesson is simple: a first-time buyer mortgage deal should be judged on lender fit and total cost, not just the rate shown on a comparison table. The first application matters, so it is worth checking the facts before committing to a product.

How much deposit do first-time buyers usually need?

Your deposit affects the loan-to-value, usually shortened to LTV. If you buy a £250,000 property with a £25,000 deposit, you borrow £225,000. That is a 90% LTV mortgage.

Many first-time buyers look at 95% mortgages, where they have a 5% deposit. These products may be available from some lenders at different times, but availability, pricing and criteria can change. A 5% deposit does not mean approval is automatic.

A bigger deposit can sometimes improve product choice because it lowers the LTV, but it is not a guarantee of acceptance. Lenders still check affordability, credit history, income evidence, deposit source and the property.

You should also keep money aside for buying costs. GOV.UK’s home-buying guidance explains that buyers may need to budget for costs such as conveyancing, surveys, searches and removals. You may also need funds for buildings insurance, furniture, repairs, service charges or immediate maintenance.

Do first-time buyers get 50% off?

Some first-time buyers may come across the First Homes scheme, which GOV.UK describes as allowing eligible first-time buyers to buy certain homes for 30% to 50% less than market value.

This is not a general 50% discount for all first-time buyers. It applies only where the scheme is available, the buyer meets the rules and the property qualifies. The home must usually be the buyer’s only or main residence, and there are eligibility, local authority and resale conditions to consider.

If you are considering First Homes or another affordable home ownership route, check the current GOV.UK guidance, speak to the developer or local authority where relevant, and make sure your solicitor and mortgage adviser understand the scheme before you commit.

Are 100% mortgages available for first-time buyers?

Some lenders have offered no-deposit or 100% mortgage-style products at certain times, often with strict criteria. These are not standard options for every first-time buyer and may involve specific requirements, such as rental history, affordability checks, family support or other conditions.

The key point is that a 100% mortgage means you are borrowing the full purchase price. That can increase risk if property values fall, because you may have little or no equity at the start. Product choice may also be limited compared with buyers who have a deposit.

Before considering a 100% mortgage, ask:

• What exact criteria must I meet?
• Is my rent history relevant to the lender?
• What happens if the property value falls?
• Are there higher rates, fees or restrictions?
• Could saving a deposit give me more choice or reduce risk?
• Would family-supported options be safer or more suitable?

A no-deposit route may be worth exploring for some buyers, but it should be assessed carefully rather than treated as an easy shortcut.

Is a £30,000 salary enough to buy a house?

A £30,000 salary may be enough in some situations and not enough in others. The answer depends on the property price, deposit, debts, regular commitments, credit history, location and whether you are buying alone or with another applicant.

Lenders do not use salary alone. They usually assess affordability by looking at income and outgoings together. Student loan deductions, childcare, car finance, credit card balances, dependants and other commitments can all affect borrowing.

A simple affordability sense-check is:

If your budget is tight, it can help to speak to a mortgage adviser before viewing properties at the top of your range. You can also read our guide on how much mortgage can I afford.

What documents do first-time buyers need for a mortgage?

The exact documents depend on your situation and lender, but first-time buyers are often asked for:

Deposit evidence is a common delay. If money has moved between accounts, lenders and solicitors may ask for a clear paper trail. If the deposit is gifted, the person gifting the money may also need to provide evidence and sign a declaration.

How do lenders assess first-time buyer mortgage applications?

Lenders usually assess both the borrower and the property.

Income

Lenders may consider:

• basic salary;
• overtime;
• bonus or commission;
• self-employed income;
• contractor income;
• second-job income;
• pension or benefit income where acceptable;
• maintenance income where evidenced and acceptable.

Not all income is treated equally. Some lenders use an average. Some use only part of variable income. Some require a track record. This is why the most suitable lender for one first-time buyer may not be suitable for another.

Outgoings and commitments

Lenders usually look at regular commitments such as loans, credit cards, car finance, childcare, maintenance payments, student loan deductions, dependants and household expenditure.

A strong salary does not automatically mean high borrowing if commitments are also high.

Credit history

Your credit history can affect both lender choice and product availability. Lenders may consider missed payments, defaults, county court judgments, insolvency history, credit utilisation and general account conduct.

A credit issue does not always prevent a mortgage, but the detail matters: when it happened, how much it was, whether it is satisfied and what your credit conduct has been like since.

Deposit source

Lenders often want to know where the deposit came from. Common sources include savings, family gift, inheritance, sale proceeds, investment maturity or other acceptable sources.

If the deposit is a loan rather than a gift, it may affect affordability and lender acceptability.

Property type

The property is the lender’s security, so it must also fit the lender’s rules. Issues can include:

• lease length;
• new-build property;
• flats above commercial premises;
• high-rise buildings;
• cladding or building safety documentation;
• unusual construction;
• property condition;
• service charges and ground rent;
• shared access or title issues.

An agreement in principle is not a mortgage offer. The lender’s valuation, underwriting and legal checks still need to be completed.

What can make first-time buyer mortgage deals harder?

You may need more specific advice if:

• you are self-employed or recently changed job;
• your income includes overtime, commission, bonus or multiple jobs;
• you have a gifted deposit;
• you have credit issues;
• you are buying a flat, new build or unusual property;
• you are close to your affordability limit;
• you are using a government or affordable home ownership scheme;
• you have a visa or limited UK residency history;
• you are buying with another person but only one of you will own the property;
• you are considering a family-supported mortgage;
• you have a tight deadline.

You may not need a broker if your situation is simple, you are comfortable comparing products yourself and you understand fees, rate types, early repayment charges, affordability and lender criteria. Some first-time buyers do apply directly.

However, if there is uncertainty, it can be worth checking before applying. A poorly matched application can waste time and create stress, especially if you are already negotiating on a property.

Fixed rate or variable rate: which is better for a first-time buyer?

A fixed rate gives predictable monthly payments for a set period. That can be helpful when you are moving into your first home and dealing with new bills such as council tax, utilities, insurance and maintenance.

A tracker or variable rate can move up or down. The Bank of England’s Bank Rate influences the wider interest-rate environment, although lenders set mortgage rates based on several factors including funding costs, risk, competition and product design.

The right answer depends on your budget and plans. If a payment rise would cause serious pressure, certainty may be more valuable than chasing the lowest initial cost.

What mistakes should first-time buyers avoid?

Choosing the lowest rate without comparing total cost

A low rate can be appealing, but a high product fee may change the true cost. Compare the total cost over the period you expect to keep the mortgage.

Forgetting the full cost of buying

The deposit is not the only cost. Budget for legal work, searches, survey costs, moving expenses, insurance, furniture and repairs.

Applying before checking lender criteria

A mortgage may look available online, but the lender may not accept your income type, deposit source, credit profile or property.

Assuming an agreement in principle is approval

An agreement in principle can be useful, but it is not a formal mortgage offer. Full underwriting, valuation and legal checks still matter.

Ignoring early repayment charges

If you may move, overpay or change the mortgage before the deal ends, early repayment charges can be important.

Borrowing the maximum without stress-testing your own budget

A lender’s affordability assessment is important, but you should also test your own budget. Consider what happens if bills rise, income changes or unexpected costs appear.

Leaving documents until the last minute

Missing payslips, unclear deposit evidence or incomplete bank statements can slow the process. Prepare early, especially if family money is involved.

What could first-time buyer mortgage deals look like in practice?

Example 1: straightforward employed buyer with saved deposit

A buyer has stable employed income, a deposit built from savings and a clean credit history. They are buying a standard residential house.

Lender choice may be relatively broad, subject to affordability, valuation and full underwriting. The main decision may be whether a product fee is worth paying for a lower rate and whether the fixed period matches their plans.

Example 2: buyer with a gifted deposit

A buyer has some savings, but part of the deposit is gifted by a parent.

This is common, but the lender will usually want evidence of the gift and may require a signed gifted deposit letter. The solicitor may also need source-of-funds evidence. If the money is actually a repayable loan, lender acceptability and affordability may be affected.

Example 3: buyer with variable income

A buyer earns basic salary plus overtime and bonus. They want the lender to use the full income figure.

Some lenders may consider variable income, but not all will use it in the same way. They may ask for payslips, P60s or a track record. Some may average the income or use only a percentage. In this case, lender selection can matter more than the lowest advertised rate.

Example 4: buyer with a small credit issue

A buyer had a missed payment in the past but has otherwise kept accounts well run.

This does not automatically rule out a mortgage. The outcome may depend on the type of missed payment, when it happened, the amount, whether it is now up to date, the deposit size and the lender’s criteria.

Example 5: buyer comparing low-rate/high-fee against higher-rate/no-fee

A buyer sees one deal with a lower rate and a product fee, and another with a higher rate and no fee.

The lower-rate deal may look better at first, but it may not be cheaper once the fee is included. The answer depends on the mortgage size, monthly payment difference, product period and whether the fee is paid upfront or added to the loan.

When should you speak to a mortgage broker?

A broker can help you understand:

• how lenders may assess your income;
• whether your deposit source may raise questions;
• how your credit history may affect lender choice;
• whether the property type could be an issue;
• how product fees affect overall cost;
• whether a fixed, tracker or variable product may suit your plans;
• what documents to prepare before applying;
• what your options may be if the first route is not available.

You may especially benefit from advice if you are self-employed, have variable income, use a gifted deposit, have credit issues, are buying a flat or new build, or are close to your affordability limit.

We cannot promise a lender will approve your case. What we can do is help you review the facts, compare suitable routes and understand what lenders may want to see.

FAQs

What is the best first-time buyer mortgage deal?

The best deal is the one that fits your affordability, deposit, credit profile, property and future plans. It is not always the lowest headline rate. Fees, early repayment charges, incentives and lender criteria all matter.

Can first-time buyers get a mortgage with a 5% deposit?

Some lenders may offer 95% LTV mortgages at certain times, subject to criteria and affordability. Product availability and pricing can change, and approval is not guaranteed.

Do first-time buyers get special mortgage rates?

Some lenders offer first-time buyer products or incentives, such as cashback or low-deposit options. However, these still depend on lender criteria and may not be cheaper overall than other products.

Can I get a mortgage with a gifted deposit?

Many lenders consider gifted deposits, commonly from family members, but they usually require evidence and a signed declaration confirming the nature of the gift. If the money is repayable, that can affect affordability and lender acceptability.

Is an agreement in principle enough to make an offer?

An agreement in principle can help show that a lender may be willing to consider you, based on limited information. It is not a formal mortgage offer. Full checks, valuation and legal work still need to happen.

Should I use a mortgage broker as a first-time buyer?

You can apply directly if you are comfortable comparing lenders and understanding criteria. A broker may be useful if your income, deposit, credit history, property type or timing is not straightforward, or if you want help comparing total cost rather than headline rates.
