How a Mortgage Works From Start to Finish

You're thinking about buying, or you've just started the process, and the mortgage itself is a black box of terms. This walks the whole thing from beginning to end: what a mortgage actually is, then each stage of what's happening to your money and why. For first-timers who want to follow the process rather than nod along to it.

<task>
**Explain the mortgage from beginning to end**
1. Describe what a mortgage is in one sentence: a loan secured against a property.
2. Walk through the five main stages: affordability assessment, agreement in principle, property search and offer, formal mortgage application and valuation, and completion.
3. For each stage, explain: what happens, who is involved, how long it typically takes, and one thing that can go wrong.

**Clarify key terms**
4. Define five terms a first-time buyer needs to understand: LTV (loan to value), fixed rate versus variable rate, early repayment charge, conveyancing, and exchange of contracts.

**One thing most people do not realise**
5. Explain why the interest rate is less important than the total cost of the mortgage including fees, and how to compare mortgages correctly.
