Explore the stages, not a fixed schedule. Legal work, lending and property checks often overlap. This is a guide, not a tracker of your application. Purchase references to exchange and completion use England and Wales; ask your solicitor about Scotland or Northern Ireland.
Stage 1 of 6
Set your budget
Allow for the deposit, mortgage payments and the other costs of buying. An agreement in principle is an initial indication, not a mortgage offer.
Your preparation
List savings, income, commitments and moving costs.
Who is involved
You and your mortgage adviser
Checkpoint
You understand the budget and the evidence still needed.
The lender reviews the application and arranges its property assessment. A lender valuation is different from a survey commissioned for your own understanding of condition.
Your preparation
Respond to document requests; discuss the survey you need.
Who is involved
Lender, adviser and surveyor
Checkpoint
Application queries and property concerns have an owner.

A general UK mortgage preparation guide. Legal stages and purchase taxes vary by nation.
Start with the borrowing purpose
Say whether you are buying a home, moving, remortgaging or financing a rental. Explain who will own the property and who will live there. Include the price or value, deposit or equity, preferred monthly budget and any genuine deadline. These facts help identify which kind of mortgage assessment is needed.
Build an accurate picture of affordability
A lender considers income, commitments, household spending, credit history and the proposed term. A salary multiple or online result is only a starting illustration. Variable pay, company profits, overseas earnings and short employment histories need context and evidence; lenders do not all treat them in the same way.
Make your own budget alongside the lender assessment. Include service charges, insurance, maintenance and room for changes in income or payments. A larger maximum loan is not automatically the right amount for your plans.
Prepare evidence that tells one consistent story
Typically, start with identity and address records, income evidence, recent bank statements, deposit history and details of debts. Employed applicants may need payslips and a P60; self-employed applicants may need accounts, tax calculations and matching tax year overviews. The exact records and periods depend on the lender and circumstances.
Explain unusual credits, changing earnings, gifts or transfers before submitting. Keep originals and complete pages. Start a website enquiry with an outline; Jack will agree a secure route for detailed records.
Compare the structure and the full cost
Discuss repayment versus interest-only, term length, fixed or variable rates, overpayment limits, early repayment charges and any moving plans. Interest-only needs an acceptable plan to repay the capital. Compare products over the same period, including fees and the remaining balance. Adding a fee to the loan also increases borrowing and interest.
Know what each decision means
An agreement in principle is an early indication, not final approval. A full application lets the lender examine the evidence and property. Underwriting queries and a valuation can change the outcome. A written mortgage offer sets out the proposed terms and conditions; read these with your adviser and solicitor.
Avoid treating a quoted turnaround as a completion promise. Keep a record of outstanding requests and who owns each one. Tell Jack promptly about changes to employment, borrowing, purchase price or deposit source.
Keep the mortgage and legal work connected
The mortgage offer is one part of the purchase. Your conveyancer checks the legal title and transaction, while your surveyor investigates condition within the agreed survey scope. The legal team confirms when you can safely commit. For a remortgage, compare the new completion date with the existing deal end and any early repayment charge.

Useful answers
Questions before you start
Does a good credit score guarantee a mortgage?
No. Lenders use their own criteria and review the underlying record, income, commitments and property. Correct errors and explain relevant history rather than relying on a single score.
An assessment may be possible. The business, evidence, currency, residence and lender criteria all matter. Use the dedicated guides, then discuss your exact circumstances.
Find out the reason before making further applications. A different lender may assess matters differently, but repeated applications without resolving the issue can be unhelpful.
