To get a mortgage in 5 essential steps, you usually need to check your finances, understand what you may be able to afford, get an agreement in principle, choose a suitable lender and mortgage route, then submit a full application with the right evidence.

The process is simple on paper. In practice, your income, deposit, credit history, debts, property type, employment status and documents can all affect the route.

This guide is general information only and is not personal mortgage advice. Your options depend on your circumstances and lender criteria at the time you apply.

Key takeaway: To get a mortgage in 5 essential steps, you usually need to check your finances, understand what you may be able to afford, get an agreement in principle, choose a suitable lender and mortgage route, then submit a full application with the right evidence.

What are the 5 essential steps to getting a mortgage?

The 5 essential steps are:

Step What you do What the lender is likely to care about
1 Check your finances and deposit Income, outgoings, debts, credit history, savings and purchase costs
2 Work out affordability Whether the mortgage looks affordable now and under the lender’s rules
3 Get an agreement in principle Initial borrowing indication, usually before making an offer
4 Choose the right lender and mortgage route Lender fit, property type, deposit source, income structure and product features
5 Submit the full mortgage application Documents, underwriting, credit checks, valuation and final mortgage offer decision

An agreement in principle is not a mortgage offer. A lender can still decline, reduce the loan amount or ask further questions after reviewing your documents or valuing the property.

The strongest route is not simply the lowest headline rate. It is the lender and product that fit your circumstances, your evidence and the property you want to buy.

If you want help checking which route may fit your circumstances before you apply, you can make an enquiry with The Mortgage Blog.

Step 1: Check your finances before looking at properties

Start with your real budget, not the maximum property price you would like to reach.

You should review:

  • your deposit amount
  • your income and whether it is stable, variable or self-employed
  • regular spending
  • credit commitments, including loans, credit cards, car finance and childcare costs
  • emergency savings after completion
  • expected legal, survey, valuation, moving and insurance costs
  • whether you may need to pay Stamp Duty Land Tax or another property tax
  • your credit reports with the main credit reference agencies

public guidance’s home-buying guidance encourages buyers to consider the wider cost of buying, not just the mortgage payment. GOV.UK also explains that buyers should prepare for costs such as legal fees, surveys, searches and removals.

A common mistake is using every available pound for the deposit and leaving no buffer for moving costs, repairs or a change in circumstances. A bigger deposit can help, but a stretched monthly budget can still be risky.

Quick self-check before you start

Question Why it matters
Do you know your deposit source? Lenders and solicitors may ask for evidence of savings, gifts or other funds.
Have you checked your credit reports? Incorrect addresses, old linked accounts or missed payments can cause delays.
Are your bank statements clean and explainable? Lenders may review spending patterns, overdraft use and undisclosed commitments.
Is your income easy to evidence? Variable, bonus, contractor or self-employed income can be treated differently.
Have you allowed for buying costs? Legal fees, surveys, removals and tax can change what you can comfortably afford.

Step 2: Work out affordability, not just borrowing power

Mortgage affordability is not just your income multiplied by a fixed number. Lenders usually assess a mixture of income, commitments, household costs, dependants, credit profile, deposit size, loan-to-value, mortgage term and their own affordability rules.

The Bank of England Bank Rate affects the wider interest-rate environment, although individual mortgage rates are set by lenders and can move for several reasons. This matters because affordability can change if rates, lender stress testing or product availability changes.

You may find affordability more straightforward if you are employed on a basic salary and have low debts. It can be more complex if you rely on:

  • overtime
  • bonus or commission
  • benefits income
  • zero-hours or variable-hours work
  • contractor income
  • self-employed profits
  • company director income
  • income from multiple jobs
  • maintenance payments

Different lenders can treat the same income in different ways. One lender may use a higher proportion of bonus income, while another may average it differently or ignore it if the track record is too short.

What salary do you need for a £300,000 mortgage?

There is no single salary that guarantees a £300,000 mortgage.

Some borrowers use rough income multiples as a starting point, but they can be misleading. A £300,000 mortgage may be treated very differently depending on deposit size, debts, credit history, dependants, mortgage term, interest rate, income type and lender criteria.

For example:

Borrower profile Why the answer may differ
Employed applicant with a strong deposit and low debts Affordability may be more straightforward, but still depends on lender rules.
Couple with childcare costs and car finance Higher household income may still be constrained by commitments.
Self-employed borrower Lenders may use accounts, tax calculations or company income differently.
Applicant with recent credit issues Lender choice may narrow and borrowing could be affected.
Longer mortgage term Monthly payments may reduce, but total interest may be higher and age rules may apply.

Use calculators only as a rough guide. Before making an offer, check affordability with a lender or mortgage adviser using your real income and commitments.

Step 3: Get an agreement in principle

An agreement in principle, sometimes called a decision in principle or mortgage in principle, gives an indication of what a lender may be prepared to lend based on initial information.

It can help you:

  • understand a realistic property budget
  • show estate agents that you have started checking your borrowing position
  • identify possible issues before a full application
  • make an offer with more confidence

However, it is not a mortgage offer. The lender still needs to review your documents, complete underwriting, carry out credit checks and assess the property.

Some agreements in principle involve a soft credit search. Others may involve a hard credit search. Check this before proceeding if you are concerned about the impact on your credit file.

Agreement in principle vs mortgage offer

Point Agreement in principle Mortgage offer
When it happens Usually before making an offer or before full application After full application, underwriting and valuation
What it proves Initial borrowing indication only The lender is prepared to lend, subject to offer conditions
Is it guaranteed? No Still subject to conditions and completion requirements
Documents checked? Often limited More detailed income, deposit, identity, bank and property checks
Property assessed? Usually not fully Usually includes a lender valuation

Step 4: Choose the right lender and mortgage route

This is where many borrowers focus too heavily on the rate and not enough on lender fit.

A suitable lender route depends on more than the monthly payment. You may need to consider:

  • fixed rate, tracker rate or variable rate options
  • product fees and valuation fees
  • early repayment charges
  • overpayment flexibility
  • portability if you may move again
  • mortgage term and total interest cost
  • lender criteria for your income type
  • whether the property is acceptable to that lender
  • whether your deposit source is acceptable
  • how quickly the lender can process the case

The lowest advertised rate may not help if the lender will not accept your income, deposit source, credit profile or property.

public guidance explains that borrowers can shop around themselves or get mortgage advice. The Financial Conduct Authority regulates mortgage advice, and a regulated recommendation should consider suitability, not just the cheapest-looking product.

A broker can be especially useful where your case is not straightforward, including if you are self-employed, have credit issues, use a gifted deposit, need high loan-to-value borrowing, are buying a flat with lease or building-safety considerations, or need a lender comfortable with variable income.

A common trap: treating the agreement in principle as the hard part

Imagine a first-time buyer who has a steady salary, some annual bonus income and a deposit made up of savings plus a gift from a parent. They get an agreement in principle online and use that figure as their maximum budget. A few weeks later, they have an offer accepted on a leasehold flat and apply to the lender that showed the cheapest monthly payment.

The problem is not one single issue. It is the combination. The lender may only use part of the bonus income, the buyer has recently taken out car finance, the gifted deposit needs a clear letter and bank trail, and the flat has lease details and service charges that need checking. The agreement in principle looked comfortable, but the full application now depends on documents, affordability and property criteria all lining up.

A broker would usually slow this down before the offer stage and check:

Point to check Why it matters
Bonus income Lenders may average it, cap it or ignore it without enough history.
Car finance Monthly commitments can reduce affordability more than buyers expect.
Gifted deposit The lender and solicitor may both need evidence and confirmation it is not repayable.
Leasehold flat Lease length, ground rent, service charge and building-safety points can affect lender acceptability.
Product choice The lowest rate is not useful if the lender is a poor fit for the buyer or property.

The practical lesson is that the five mortgage steps should not be treated as separate boxes. Affordability, lender choice, deposit evidence and property risk need checking together before you rely on a budget or commit emotionally to a purchase.

Step 5: Submit the full mortgage application

Once you have chosen a lender and mortgage product, the full application begins.

You will usually need to provide:

  • proof of identity
  • proof of address
  • recent payslips, accounts, tax calculations or other income evidence
  • bank statements
  • evidence of deposit
  • details of loans, credit cards and other commitments
  • property details
  • estate agent details
  • solicitor or conveyancer details

The lender will assess your application and usually arrange a valuation of the property. The valuation is for the lender’s benefit. It is not the same as a full building survey.

If the lender is satisfied, it may issue a mortgage offer. Your solicitor or conveyancer then deals with the legal work, searches, enquiries, exchange of contracts and completion.

What are the main stages after you apply?

The mortgage process can be described in different ways, but most purchases move through these practical stages:

Stage What happens What can delay it
Agreement in principle Initial borrowing indication Incorrect information, credit issues, unsuitable lender
Offer accepted on property You agree a price with the seller Chain issues, missing proof of funds, slow negotiations
Full application Lender receives detailed application and documents Missing documents, unclear income or deposit evidence
Underwriting and valuation Lender checks borrower and property risk Valuation concerns, property defects, further questions
Mortgage offer and legal work Offer issued if accepted; solicitor completes checks Searches, lease issues, title problems, enquiries
Exchange and completion Contracts exchanged and purchase completes Chain delays, funds not ready, last-minute legal issues

A mortgage offer is a major milestone, but it is not the same as owning the property. Completion only happens once the legal work is finished and funds are released.

What documents make a mortgage application easier?

Documents are not just admin. They are how the lender checks that the application matches the facts.

Core documents

Document Why it matters
Passport or driving licence Confirms identity.
Proof of address Helps verify your residential history.
Payslips or employment evidence Supports employed income.
P60 or employment contract May help evidence annual income or job details.
Bank statements Shows income credits, spending, commitments and account conduct.
Deposit evidence Shows where the deposit has come from.
Gifted deposit letter, if relevant Confirms the gift and whether it is repayable.
Credit commitment details Helps affordability assessment.
Property details Allows the lender to assess the security.
Solicitor details Needed to progress the legal side.

Extra documents for self-employed applicants

You may also need:

  • SA302s or tax calculations
  • tax year overviews
  • company accounts
  • accountant’s certificate, if requested
  • business bank statements
  • dividend vouchers or salary evidence
  • details of retained profits, if relevant to the lender

GOV.UK provides information on Self Assessment tax returns, which may be relevant if your lender asks for tax-year evidence.

What can make getting a mortgage harder?

Getting a mortgage can be more difficult if the lender sees higher risk in the borrower, the property or the evidence.

Common issues include:

  • recent missed payments, defaults, county court judgments or insolvency history
  • high credit card balances or loan commitments
  • heavy overdraft use
  • unstable or recently changed income
  • short self-employed trading history
  • unclear deposit source
  • gifted deposits without a clear paper trail
  • overseas funds that are difficult to evidence
  • property defects or unusual construction
  • short leases or leasehold issues
  • flats with cladding or building-safety concerns
  • new-build incentives that affect valuation or lender criteria
  • buying at auction with tight timescales
  • relying on optimistic assumptions about income or property value

These issues do not always make a mortgage impossible. They do mean lender choice and evidence become more important.

What should you check before viewing, offering and applying?

A useful mortgage plan changes at each stage. The checks before viewing are different from the checks before a full application.

Stage What to check Why it matters
Before viewing Deposit, broad affordability, credit reports, buying costs Avoids looking at homes well outside your workable budget.
Before making an offer Agreement in principle, likely monthly payment, property type, lease or title concerns Helps reduce the risk of offering on a property your lender may not accept.
Before full application Final lender fit, product choice, documents, solicitor details, deposit evidence Reduces avoidable delays and underwriting questions.
Before exchange Mortgage offer conditions, survey findings, legal enquiries, insurance needs Exchange is legally binding in England and Wales, so unresolved issues matter.

If you are buying in Scotland, the process and timing can differ, so take advice from your solicitor and mortgage adviser before relying on an agreement in principle or making an offer.

What property issues can affect a mortgage?

The lender is not only assessing you. It is also assessing the property as security for the loan.

Property issues that may affect the mortgage route include:

  • lease length and ground rent terms
  • service charges and major works
  • cladding or building-safety issues
  • non-standard construction
  • structural movement or damp
  • Japanese knotweed
  • commercial use nearby or above the property
  • flying freeholds
  • shared ownership terms
  • new-build warranties
  • valuation being lower than the purchase price

GOV.UK provides guidance on leasehold property, and your solicitor should explain legal risks before exchange. A lender valuation is not a substitute for legal advice or a survey.

Should you go direct to a lender or use a mortgage broker?

You can apply directly to a lender, use a broker, or combine your own research with advice.

Route Potential advantages Points to watch
Direct to lender You deal with the lender yourself; may suit simple cases You only see that lender’s products and criteria.
Mortgage broker Can compare multiple lenders and help with criteria fit Check whether the broker is whole-of-market or restricted, and ask about fees.
Adviser plus your own research Helps you understand the trade-offs Product choice should still be based on suitability, not headline rate alone.

A broker may add value where the main challenge is not finding a rate but finding a lender that fits your circumstances.

What would a broker check first?

A broker would usually start by checking whether the case fits lender criteria before comparing products.

Broker check Why it matters What a stronger case shows
Borrower profile Lenders assess income, credit, age, dependants and commitments differently. The borrower’s circumstances can be evidenced clearly.
Affordability A high income does not always mean high borrowing if commitments are high. The budget works after debts, household costs and future changes are considered.
Deposit source Lenders and solicitors need to understand where funds came from. Savings, gifts or sale proceeds have a clear paper trail.
Property risk The property is the lender’s security. Tenure, construction, valuation and legal points are acceptable or understood.
Timing Good cases can still fail if deadlines are unrealistic. There is enough time for documents, valuation, underwriting and legal work.
Fallback route A one-lender plan can be fragile. There is another route if the first lender or valuation does not work.

How do interest rates affect your decision in 2026 and 2027?

Mortgage rates can change before you apply, before your offer is issued or before a current deal ends. The Bank of England Bank Rate is one influence on the wider market, but lenders price mortgages using several factors.

When choosing a mortgage, think about:

  • whether you value payment certainty
  • whether you may move or repay early
  • whether early repayment charges would restrict you
  • what happens when the initial deal ends
  • whether fees make a lower rate less attractive
  • whether you could still afford payments if costs rise in future

A fixed rate may give payment certainty for a period. A tracker or variable rate may move up or down. The right choice depends on your circumstances, risk tolerance and plans.

Red flags and trade-offs before you apply

Before committing to a route, ask these questions:

  • What could make the lender decline or reduce the loan?
  • Is the deposit source fully evidenced?
  • Do the bank statements support the application?
  • What happens if the valuation is lower than the agreed price?
  • Is the property acceptable to the likely lender?
  • Are you choosing the lowest rate, or the most suitable overall route?
  • What are the total costs, including fees and early repayment charges?
  • What is the fallback if the preferred lender does not work?

A clean application is not just about having enough income. It is about making sure the borrower, property, deposit, documents and timing all support the same story.

When should you speak to a mortgage adviser?

You may want to speak to a mortgage adviser before applying if:

  • you are a first-time buyer and unsure where to start
  • you are self-employed or a company director
  • your income includes overtime, commission, bonus or benefits
  • you have recent credit issues
  • you have high existing debts
  • your deposit is gifted or from several sources
  • you are buying a flat, leasehold property or new-build home
  • you are buying at auction
  • you need to move quickly
  • you have been declined elsewhere
  • you are unsure whether to choose a fixed, tracker or variable rate

If your situation is straightforward, you may still want advice to compare routes and understand the trade-offs. If it is complex, advice can help avoid applying to a lender that was unlikely to fit from the start.

FAQs

What is the key point on how to get a mortgage in 5 essential steps?

The key point is to assess your finances, check affordability, get an agreement in principle, choose a suitable lender and mortgage route, then submit a full application with the right evidence. Each step depends on your income, deposit, credit history, property and lender criteria.

What are the 5 stages of a mortgage?

A practical version of the 5 stages is: preparation, agreement in principle, property offer, full mortgage application, then mortgage offer and completion. Some guides split these into more stages, including valuation, underwriting and legal work.

Is an agreement in principle the same as a mortgage offer?

No. An agreement in principle is only an initial indication. A mortgage offer usually comes after the lender has assessed your full application, documents, credit position and the property valuation.

Do I need an agreement in principle before viewing properties?

You do not usually need one legally before viewing, but it can help show estate agents and sellers that you have started checking your borrowing position. It can also help you avoid viewing properties outside your realistic budget.

How do lenders usually assess a mortgage application?

Lenders usually assess your income, spending, debts, credit history, deposit, age, mortgage term and the property. They also apply their own affordability rules and lending criteria, which can vary between lenders.

What can improve a mortgage application?

Clear income evidence, sensible credit use, a well-evidenced deposit, accurate documents, stable account conduct and choosing a lender that fits your circumstances can all help make an application cleaner. They do not guarantee approval.

What can make getting a mortgage harder?

Recent credit issues, high debts, variable income, a small deposit, unclear deposit source or an unusual property can make getting a mortgage harder. These issues may narrow lender choice or require more evidence.

Can I get a mortgage if I am self-employed?

Yes, many self-employed people get mortgages, but the evidence can be different. Lenders may ask for tax calculations, tax year overviews, accounts, business bank statements or accountant information. The amount used for affordability depends on lender criteria.

Can I get a mortgage with bad credit?

It may be possible, depending on the type, date, amount and reason for the credit issue, as well as your deposit and current circumstances. Recent or serious credit problems usually make lender choice more important.

What documents do I need for a mortgage application?

You will usually need proof of identity, proof of address, income evidence, bank statements, deposit evidence and details of credit commitments. Self-employed applicants and applicants with gifted deposits may need additional documents.

What happens after the mortgage offer is issued?

Your solicitor or conveyancer continues the legal work, including searches, enquiries and preparing for exchange and completion. You should check any mortgage offer conditions and make sure insurance, deposit funds and completion arrangements are ready.

Can getting a mortgage be guaranteed?

No. A mortgage cannot be guaranteed. Even an agreement in principle can change after full underwriting, document checks, credit checks or property valuation.

Seafarers Mortgages: Navigating the Waters

Yes, seafarers can often get a UK mortgage, but the lender will usually look more closely at your residency, income currency, contract pattern, tax position, and time spent outside the UK. The key is not whether “seafarer mortgages” exist as a separate product, but whether your application is packaged for a lender that understands seafarer income.

How Do Mortgages Work? The way to start Buying Your Home

A mortgage is a loan secured against a property, usually used to help you buy a home when you do not have the full purchase price in cash. In practice, everything about mortgages comes down to four things: how much you borrow, how you repay it, what interest rate you pay, and whether the lender is comfortable with your income, deposit, credit profile and the property.
