Quick Answer
In short: Getting your first mortgage involves saving a deposit, checking your credit report, getting a mortgage agreement in principle, finding a property, applying formally for your mortgage with supporting documentation, then progressing through valuation, legal work, and completion. Each stage has specific requirements, and preparing thoroughly at each step helps the overall process run more smoothly.
Key Takeaways
- A mortgage agreement in principle gives you an indication of how much you could borrow, useful before you start viewing properties seriously.
- Lenders assess affordability based on your income, existing financial commitments, and credit history, not just your deposit size.
- The formal mortgage application requires substantial documentation, including proof of income, bank statements, and identification.
- A property valuation and legal conveyancing process both occur after your mortgage application is accepted, before completion.
- Using an independent mortgage broker can help navigate the process and potentially access deals not directly available to individual applicants.
Step 1: Save Your Deposit and Check Your Credit Report
Before beginning the mortgage process seriously, ensure you have your deposit saved, or a clear plan to do so, and check your credit report for accuracy. Correcting any errors and understanding your current credit position helps set realistic expectations for the mortgage process ahead.
Step 2: Get a Mortgage Agreement in Principle
A mortgage agreement in principle (sometimes called a decision in principle) is an indication from a lender of how much they might be willing to lend you, based on preliminary information about your income and circumstances. This isn’t a guaranteed mortgage offer, but it provides a useful, realistic budget for property viewing, and is often required by estate agents before they’ll accept an offer from you.
Step 3: Find Your Property and Have an Offer Accepted
With your agreement in principle providing a realistic budget, you can begin viewing properties seriously. Once you’ve found a suitable property and had an offer accepted, you’re ready to progress to a formal mortgage application.
Step 4: Submit Your Formal Mortgage Application
This involves providing detailed documentation, including proof of income (payslips or, for the self-employed, tax returns), bank statements, identification, and details of the specific property you’re purchasing. The lender uses this information to conduct a full affordability assessment, considering your income, existing financial commitments, and credit history.
Step 5: Property Valuation
Once your application is submitted, the lender arranges a valuation of the property, confirming it’s worth the amount you’re paying and suitable security for the mortgage. This is distinct from a full structural survey, which you may choose to arrange separately for your own peace of mind about the property’s condition.
Step 6: Legal Work (Conveyancing)
A solicitor or licensed conveyancer handles the legal work involved in transferring property ownership, including property searches, reviewing the contract, and handling the exchange of contracts and eventual completion. This typically runs alongside the mortgage underwriting process.
Step 7: Mortgage Offer and Exchange of Contracts
Once the lender is satisfied with the valuation and your application, they issue a formal mortgage offer. Following this, and once all legal work is complete, contracts are exchanged, making the purchase legally binding, with a completion date agreed for the actual transfer of ownership.
Step 8: Completion
On completion day, the remaining funds are transferred, legal ownership passes to you, and you receive the keys to your new home.
Comparison Table: Key Mortgage Process Stages
| Stage | What Happens | Typical Timing |
|---|---|---|
| Agreement in principle | Preliminary indication of borrowing capacity | Before serious property viewing |
| Formal application | Full documentation and affordability assessment | After an offer is accepted on a property |
| Valuation | Lender confirms property value | Shortly after formal application |
| Conveyancing | Legal work, searches, contract review | Runs throughout the process |
| Mortgage offer | Formal, binding offer from lender | After valuation and underwriting complete |
| Exchange of contracts | Purchase becomes legally binding | After all legal work is complete |
| Completion | Funds transfer, keys handed over | Agreed date after exchange |
Understanding Mortgage Affordability Assessments
Lenders assess how much they’re willing to lend based on your income, existing financial commitments (including any other debts or regular financial obligations), and your credit history. This assessment aims to ensure you could comfortably afford mortgage repayments, even accounting for potential future interest rate increases in many cases.
Being realistic about what you can genuinely afford, rather than simply the maximum a lender might offer, helps ensure long-term financial comfort with your mortgage repayments.
Using an Independent Mortgage Broker
Independent mortgage brokers can search across a wide range of lenders, potentially including deals not directly available to individual applicants, and provide guidance throughout the application process. While not essential, particularly for straightforward applications, a broker can be genuinely valuable for more complex situations, such as self-employment income or a less straightforward credit history.
Common Mistakes First-Time Buyers Make
- Not getting a mortgage agreement in principle before viewing properties. This can result in wasted time viewing properties outside your realistic budget, or difficulty having an offer accepted without this preliminary step.
- Underestimating the documentation required for formal application. Gathering payslips, bank statements, and other required documents in advance streamlines the process considerably.
- Assuming the maximum offered amount is what you should borrow. Being realistic about genuinely comfortable affordability, rather than the maximum available, supports better long-term financial stability.
- Skipping a full structural survey to save money. While the lender’s valuation confirms the property’s worth for mortgage purposes, a full survey can reveal issues affecting your decision that the valuation alone wouldn’t identify.
- Not accounting for additional costs beyond the deposit. Stamp duty (where applicable), legal fees, survey costs, and moving costs should all factor into your overall budget planning.
Real UK Scenarios
Scenario 1: Ben, obtaining a mortgage agreement in principle first.
Before beginning to view properties, Ben obtained a mortgage agreement in principle, giving him a realistic, specific budget that helped him focus his property search effectively and demonstrate seriousness to estate agents.
Scenario 2: Priya, using a mortgage broker for her self-employed income.
As a self-employed applicant with variable income, Priya used an independent mortgage broker who helped navigate lenders with more suitable criteria for her specific income situation, ultimately securing a mortgage more efficiently than she might have managed independently.
Scenario 3: Marcus, arranging an independent structural survey.
Beyond the lender’s standard valuation, Marcus arranged a full structural survey for his own peace of mind, which revealed a specific issue requiring negotiation with the seller before he proceeded with the purchase.

Frequently Asked Questions
What is a mortgage agreement in principle?
It’s a preliminary indication from a lender of how much they might be willing to lend you, based on initial information, useful for establishing a realistic budget before serious property viewing.
How much documentation do I need for a mortgage application?
Typically proof of income (payslips or tax returns for the self-employed), bank statements, identification, and details of the property you’re purchasing, though specific requirements vary by lender.
Do I need a full structural survey if the lender does a valuation?
The lender’s valuation confirms the property’s worth for mortgage purposes but doesn’t provide a full assessment of its condition, so many buyers choose to arrange a separate structural survey for genuine peace of mind.
Should I use a mortgage broker?
This can be valuable, particularly for more complex situations like self-employment income or a less straightforward credit history, though straightforward applications can sometimes be managed directly with a lender.
How long does the mortgage process typically take?
This varies considerably depending on individual circumstances and any property chain involved, but the process from formal application to completion often takes several weeks to a few months.
What happens between exchange of contracts and completion?
The purchase becomes legally binding at exchange, with a specific completion date agreed, at which point funds transfer and legal ownership passes to you.
What additional costs should I budget for beyond my deposit?
Stamp duty where applicable, legal fees, survey costs, and moving expenses should all factor into your overall budget planning beyond the deposit itself.
How is mortgage affordability assessed?
Lenders consider your income, existing financial commitments, and credit history, assessing whether you could comfortably afford repayments, often including a buffer for potential future interest rate increases.
Can I get a mortgage with a poor credit history?
It’s possible, though likely at a higher interest rate or through specialist lenders; improving your credit position before applying, where possible, generally provides access to better rates and terms.
What is conveyancing?
It’s the legal process of transferring property ownership, handled by a solicitor or licensed conveyancer, including property searches, contract review, and managing exchange and completion.
