First-Time Buyer Mortgage Guide: Everything You Need to Know

By Maxim Cohen·13 July 2026·8 min read

Buying your first home is one of the biggest financial decisions you'll ever make. While the process can seem complicated at first, understanding how mortgages work and preparing properly can make the journey much smoother.

Whether you're buying on your own, purchasing with a partner or receiving financial support from family members, this guide explains everything you need to know before applying for your first mortgage.

At The UK Adviser, we help first-time buyers across the UK understand their mortgage options and navigate the home-buying process with confidence.

Who Is Considered a First-Time Buyer?

Generally, you're considered a first-time buyer if you've never owned a residential property in the UK or abroad.

If you're purchasing jointly, lenders and tax rules may consider whether both applicants are first-time buyers.

Your circumstances can affect eligibility for certain mortgage products, government schemes and Stamp Duty relief.

Can First-Time Buyers Get a Mortgage?

Yes.

Many lenders actively support first-time buyers and offer products specifically designed for people purchasing their first home.

As a first-time buyer, you'll usually need to demonstrate:

  • A suitable deposit
  • Sufficient income
  • Good affordability
  • Acceptable credit history
  • Evidence of your identity and address

Every lender has its own criteria, which is why professional mortgage advice can be valuable.

How Much Deposit Do You Need?

The amount of deposit required depends on the lender and the mortgage product.

Many first-time buyers purchase with deposits starting from 5% of the property's value, although a larger deposit may provide access to more competitive mortgage products and interest rates.

For example:

  • 5% deposit
  • 10% deposit
  • 15% deposit
  • 20% deposit
  • 25% or more

Saving a larger deposit may improve both affordability and lender choice.

What Is Loan-to-Value (LTV)?

Loan-to-Value, often referred to as LTV, is the percentage of the property's value that you borrow.

For example:

  • Property Price: £300,000
  • Deposit: £30,000
  • Mortgage: £270,000
  • Loan-to-Value = 90%

Generally, lower LTV mortgages offer access to a wider range of products and potentially more competitive interest rates.

How Much Can You Borrow?

Every lender has its own affordability assessment.

The amount you may be able to borrow depends on several factors, including:

  • Income
  • Employment status
  • Deposit
  • Credit history
  • Existing financial commitments
  • Household expenditure
  • Number of applicants
  • Mortgage term

Affordability is based on much more than income alone.

What Do Mortgage Lenders Look At?

When assessing your application, lenders may consider:

  • Your income
  • Employment history
  • Credit record
  • Bank statements
  • Existing borrowing
  • Monthly expenditure
  • Deposit source
  • Property details
  • Overall affordability

Each lender applies its own underwriting criteria.

Mortgage Types Explained

There are several different mortgage products available.

Fixed Rate Mortgages

A fixed-rate mortgage means your interest rate remains the same for a specified period.

Common fixed periods include:

  • Two years
  • Three years
  • Five years
  • Ten years

Many first-time buyers choose fixed-rate mortgages because they provide certainty over monthly repayments.

Tracker Mortgages

Tracker mortgages usually move in line with an external interest rate, such as the Bank of England Base Rate.

Your monthly payments may increase or decrease depending on interest rate movements.

Variable Rate Mortgages

Variable rate mortgages can change at the lender's discretion.

Monthly repayments may therefore increase or decrease during the mortgage term.

Repayment or Interest-Only?

Most first-time buyers choose a repayment mortgage.

Each monthly payment contributes towards both:

  • Interest
  • Capital

By the end of the mortgage term, assuming all repayments have been made, the loan should be repaid in full.

Interest-only mortgages work differently and are generally less common for first-time buyers.

What Is an Agreement in Principle?

An Agreement in Principle (AIP) is an indication of how much a lender may be prepared to lend based on the information provided.

An AIP:

  • Is not a mortgage offer.
  • Can help you understand your budget.
  • May reassure estate agents and sellers that you're a serious buyer.

Some lenders use a soft credit search, while others may carry out a hard search.

Finding Your Property

Once you understand your budget, you can begin searching for properties.

When choosing a property, consider:

  • Location
  • Schools
  • Transport links
  • Future resale potential
  • Local amenities
  • Service charges
  • Ground rent
  • Lease length, where applicable

Buying the right property is about more than today's needs. It's also worth considering your future plans.

Making an Offer

When you find a property you'd like to buy, you can submit an offer through the estate agent.

The seller may:

  • Accept
  • Reject
  • Negotiate

Once your offer has been accepted, the mortgage application process usually begins.

Choosing a Solicitor or Conveyancer

Your solicitor or licensed conveyancer will deal with the legal aspects of the purchase.

This includes:

  • Property searches
  • Reviewing contracts
  • Liaising with the seller's solicitor
  • Managing completion
  • Registering ownership

Choosing an experienced conveyancer can help the transaction progress more efficiently.

Property Valuations and Surveys

Most lenders require a mortgage valuation.

This differs from a property survey.

A valuation helps the lender confirm that the property provides suitable security for the mortgage.

You may also wish to arrange:

  • HomeBuyer Report
  • Building Survey

The most appropriate survey depends on the property's age, condition and construction.

Exchange of Contracts

Once legal work has been completed and both parties are ready to proceed, contracts are exchanged.

At this stage:

  • The purchase becomes legally binding.
  • A completion date is agreed.
  • Your deposit is normally transferred.

Completion Day

Completion is the day ownership transfers to you.

Your solicitor will arrange:

  • Transfer of mortgage funds
  • Payment to the seller
  • Registration of ownership

Once completed, you can collect the keys to your new home.

Other Costs to Budget For

Buying a home involves more than your deposit.

You should also budget for:

  • Solicitor's fees
  • Survey fees
  • Mortgage arrangement fees
  • Valuation fees
  • Removal costs
  • Buildings insurance
  • Contents insurance
  • Stamp Duty, where applicable

Planning for these additional costs can help avoid surprises.

Gifted Deposits

Many first-time buyers receive financial assistance from parents or close relatives.

Most lenders accept gifted deposits, provided they meet the lender's requirements.

You may need to provide:

  • Gift letter
  • Identification
  • Evidence of funds

Your solicitor will also carry out source of funds checks.

Government Schemes

Depending on your circumstances, you may be eligible for government-backed initiatives designed to support home ownership.

Availability and eligibility can change over time, so always seek up-to-date advice before relying on any scheme.

Improving Your Chances of Approval

You may improve your mortgage application by:

  • Saving a larger deposit.
  • Maintaining a good credit history.
  • Registering on the electoral roll.
  • Avoiding unnecessary borrowing.
  • Keeping your bank accounts well managed.
  • Preparing your documents in advance.
  • Speaking to a mortgage adviser before applying.

Common Mistakes First-Time Buyers Make

Common mistakes include:

  • Looking at properties before understanding affordability.
  • Forgetting about additional buying costs.
  • Taking out new finance before applying.
  • Failing to check credit reports.
  • Applying to unsuitable lenders.
  • Not obtaining professional advice early.

Preparation can make the buying process much smoother.
