First-Time Buyer Mortgage Guide UK 2026

Most first-time buyers need a deposit of at least 5%, an income that passes the lender’s affordability checks and a clean enough credit file. Get those three right, and work out the full cost of buying before you view, and the rest of the process is very manageable.

Buying your first home involves more than finding a property. You need to understand how much you can afford, what deposit you will need, which support schemes apply and what happens between your offer being accepted and collecting the keys.

This guide takes you through the process. For detailed answers on specific questions, use our guides to first-time buyer deposits, who counts as a first-time buyer and mortgage mistakes to avoid.

What is a first-time buyer mortgage?

A first-time buyer mortgage is a home loan for someone purchasing their first property. A lender’s definition of a first-time buyer may differ from the legal definition used for tax relief or government schemes. If you have inherited, jointly owned or previously owned property, check what counts as a first-time buyer before assuming you qualify.

Which situations do lenders see most?

These are illustrative situations, not Option Finance client outcomes.

Saving a 5% deposit

You have 5% saved and a steady job. Lenders will look closely at affordability and your credit file.

Fewer lenders, so match carefully

Help from family

Parents are gifting part of the deposit. Lenders want a signed gift letter and proof of where the money came from.

Get the paperwork ready early

Self-employed first-timer

You have one or two years of accounts. The lender choice depends on how long you have traded.

Check trading history rules first

A past credit blip

A missed payment or small default a few years ago. Many lenders still say yes if it is old and settled.

Know exactly what is on your file

How much deposit do first-time buyers need?

Some first-time buyers can purchase with a 5% deposit. On a £250,000 property, that is £12,500. The deposit required depends on your circumstances, the property and the lender. A larger deposit may widen your options but does not guarantee approval or a better deal.

See the first-time buyer deposit guide and calculator for deposit comparisons, loan-to-value, gifted deposits and buying costs.

Which first-time buyer schemes are available in 2026?

Schemes have separate eligibility rules, and availability depends on where you live and what you buy. The main options are:

Mortgage Guarantee Scheme: supports 91% to 95% mortgages, so you can buy with a 5% deposit. It does not guarantee acceptance.
Lifetime ISA: a 25% bonus on up to £4,000 a year for homes up to £450,000. A replacement ISA is planned. GOV.UK explains using a Lifetime ISA to buy your first home.
Shared Ownership: buy a 10% to 75% share and pay rent on the rest.
First Homes: at least 30% off certain new homes, where your council still offers them.
Rent to Buy: rent at about 20% below market to save a deposit, in England outside London.
Right to Buy and Right to Acquire: discounts for council and some housing association tenants.
Help to Buy Wales and Scotland’s First Homes Fund: for buyers in Wales and Scotland.
Your First Home: a proposed 2.5% deposit scheme for new builds in England, announced in September 2026 and not yet open.

Some help comes from lenders or family rather than government: Deposit Unlock on some new builds, a gifted deposit, a Family Springboard mortgage, a guarantor mortgage or a joint borrower sole proprietor mortgage.

Do first-time buyers pay Stamp Duty?

In England and Northern Ireland, eligible first-time buyers can claim Stamp Duty Land Tax relief. Qualifying buyers pay no SDLT on the first £300,000 and 5% on the portion from £300,001 to £500,000, provided the purchase price does not exceed £500,000. For a full breakdown of ownership rules, thresholds and examples, read who qualifies as a first-time buyer and for Stamp Duty relief, then use our Stamp Duty calculator. | Price | First-time buyer pays | Someone who has owned before pays | | --- | --- | --- | | £250,000 | £0 | £2,500 | | £350,000 | £2,500 | £7,500 | | £450,000 | £7,500 | £12,500 | | £500,000 | £10,000 | £15,000 | | £510,000 | £15,500 (no relief above £500,000) | £15,500 |

Figures for England and Northern Ireland, worked out from GOV.UK’s published rates. The jump at £500,000 is worth knowing about if you are buying close to that price.

See also GOV.UK first-time buyer SDLT relief. Scotland and Wales use different property taxes.

How much can you borrow for your first mortgage?

Many lenders cap borrowing at around four to four-and-a-half times income. Some go higher for larger incomes or certain professions, but the amount depends on your outgoings, credit commitments, deposit and each lender’s affordability model. An income multiple is not a mortgage offer.

Start with our mortgage affordability calculator and consider how repayments would fit alongside bills, insurance and other commitments. If you are self-employed, the documents required may include tax calculations and tax year overviews. Our guide to getting a mortgage with one year’s accounts explains the options and evidence.

Illustrative example: what a first mortgage could cost each month

A £250,000 home bought with a 5% deposit of £12,500 needs a £237,500 mortgage. Over 30 years on a repayment basis, that works out at about £1,275 a month at 5% or £1,424 a month at 6%. For context, Moneyfacts put the average 2-year fixed rate at 5.96% on 15 October 2026, and rates at 95% loan-to-value are often higher than average.

These figures are illustrative only. They exclude fees, insurance and any change in rates when an initial deal ends. Your actual rate depends on the lender, your deposit and your circumstances.

The first-time buyer mortgage process step by step

Work out your budget: Review your deposit, monthly affordability and buying costs before viewing homes.
Get an Agreement in Principle (AIP): This is an indication from a lender of how much it may lend, based on the information you provide and a credit search. It is not a mortgage offer. Some lenders use a hard search at this stage, so check which type before applying.
Find a property and make an offer: Consider location, condition, tenure and likely maintenance costs, not only the asking price.
Apply for your mortgage: Once your offer is accepted, supply the documents your lender requires, which may include payslips, accounts, identification and bank statements.
Arrange the valuation and survey: The lender checks the property’s suitability as security. A lender’s valuation is not a substitute for an independent survey.
Receive the mortgage offer: The lender issues a formal offer if its checks and underwriting are satisfactory. Read any conditions carefully.
Complete the legal work: Your conveyancer checks title, searches and contracts, and explains when exchange of contracts can take place.
Exchange and complete: In England and Wales, exchange usually makes the transaction legally binding. On completion, funds are transferred and you collect the keys. The process differs in Scotland.

What fees should first-time buyers budget for?

Ask for written quotes rather than relying on generic estimates. In addition to the deposit, consider:

Conveyancing: Ask your solicitor or conveyancer for a fixed written quote including searches, disbursements and any leasehold supplements.
Survey: Decide whether you need a home survey in addition to the lender’s valuation and request a quote based on the property.
Mortgage product fees: Compare the total cost of the mortgage, not just the headline interest rate. Adding a fee to the loan means paying interest on it.
Broker fees: Ask for any advice or arrangement fee to be confirmed in writing before proceeding.
Moving and initial household costs: Get quotes for removals and allow for utilities, insurance, furniture and urgent repairs.

How can you improve your chances of approval?

Check your credit files: Correct errors and make sure your addresses and electoral registration are up to date.
Reduce unnecessary borrowing: Consider whether existing credit commitments are affecting affordability.
Keep evidence of your deposit: Lenders and conveyancers may ask where savings or gifts came from.
Avoid new financial commitments: Large loans or credit agreements before completion may change your affordability.
Prepare your paperwork: Gather identification, income evidence, bank statements and any gifted-deposit documents early.
Speak to a mortgage adviser: Discuss complex income, adverse credit or unusual properties before submitting multiple applications.

Why use a mortgage broker as a first-time buyer?

A mortgage broker can help you understand lender criteria, compare suitable products and prepare your application. We can access lenders you may not find on your own, including specialist lenders that only work through brokers. The right option depends on your circumstances and our available lender panel.

At Option Finance, we can discuss deposit sources, income evidence, affordability and the mortgage process. Your initial consultation is free. If you go ahead, our standard broker fee is £499: £299 on application, refundable if the mortgage is declined under the terms of your fee agreement, and £200 when your mortgage offer is issued.

First-time buyer mortgage FAQs

How much deposit do I actually need as a first-time buyer in 2026?

Some lenders accept a 5% deposit, although others require more. On a £250,000 home, 5% is £12,500. Your eligibility depends on the lender, property, credit history and affordability. Compare options in our deposit guide.

What government schemes are available for first-time buyers in 2026?

Options include Shared Ownership, First Homes, the Lifetime ISA and eligible 95% LTV products supported by the Mortgage Guarantee Scheme. Shared Ownership shares are usually 25% to 75%, with 10% available on some homes. Your First Home has been announced but is not yet open. Check the eligibility rules for each scheme.

How long does it take to buy your first home from start to finish?

Timescales vary with the property, lender, survey, conveyancing and any chain. An Agreement in Principle can be relatively quick, but a full mortgage offer and legal completion take longer. Your adviser and conveyancer can explain the likely stages.

Do first-time buyers pay stamp duty in 2026?

Qualifying first-time buyers in England and Northern Ireland pay no SDLT on the first £300,000 and 5% on the portion up to £500,000. Relief does not apply above £500,000. Scotland and Wales have different taxes.

Can I buy a house with bad credit as a first-time buyer?

Possibly. Lenders assess the type, amount and age of credit issues alongside affordability and deposit. Specialist lenders may consider circumstances that some mainstream lenders do not, but acceptance is not guaranteed.

Can I use a gifted deposit for my first home?

Usually, yes. Most lenders accept a gift from close family with a signed gift letter confirming it is not a loan, plus proof of where the money came from. See our gifted deposit guide.

Is a 95% mortgage a good idea?

It can get you buying sooner, but rates are usually higher and you have less equity if prices fall. Compare the cost against waiting to save 10%. Our deposit guide shows the difference.

Should I get a fixed or variable rate mortgage as a first-time buyer?

A fixed rate provides payment certainty during the fixed period, while a tracker or variable rate can change. Compare initial rates, fees, early repayment charges and what happens when the deal ends. The right choice depends on your budget and risk tolerance.
