Buying your first home is one of the most significant financial decisions you'll ever make. The mortgage process can feel overwhelming — but it doesn't have to be. This guide walks you through everything step by step.
Step 1: Check Your Credit Score
Your credit score is the first thing a lender looks at. It determines whether you'll be approved and at what interest rate. Before applying for any mortgage:
- Check your score with Experian, Equifax, or TransUnion
- Pay off existing debts or reduce credit card balances
- Avoid new credit applications in the 6 months before applying
- Register on the electoral roll at your current address
- Correct any errors on your credit file immediately
Step 2: Save Your Deposit
Most lenders require a minimum deposit of 5–10% of the property value. However, the more you save, the better the deal you'll get.
- 5% deposit: Possible but highest interest rates
- 10% deposit: Better rates, wider choice of lenders
- 20%+ deposit: Best rates available (LTV under 80%)
Step 3: Calculate What You Can Afford
Most lenders will offer 4–4.5x your annual income. For a joint application, they combine both salaries. Use our calculator to model realistic scenarios before approaching lenders.
Step 4: Get a Mortgage in Principle
A Mortgage in Principle (MIP) is a conditional agreement from a lender showing how much they'd lend you. Estate agents and sellers often require this before accepting offers. It doesn't affect your credit score if done via a soft check.
Step 5: Choose the Right Mortgage Type
Fixed Rate
Your interest rate stays the same for the fixed term (typically 2, 3, or 5 years). Ideal if you want predictable monthly payments and protection from rate rises.
Variable Rate / Tracker
Your rate moves with the Bank of England base rate. Payments can go up or down — riskier but potentially cheaper when rates fall.
Step 6: Factor in All the Costs
Your mortgage payment is just one part of owning a home. Budget for:
- Stamp Duty: First-time buyers get relief on properties up to £625,000
- Solicitor fees: £1,000–£2,500
- Survey costs: £500–£1,500
- Buildings insurance: Required by most lenders from day one
- Ongoing costs: Council tax, utilities, maintenance
Step 7: Compare Lenders
Don't just go to your bank — compare at least 3–5 lenders. Use a whole-of-market mortgage broker to access deals not available directly. Broker fees are often offset by the better rates they find.
