Frequently Asked Questions
How much deposit do I need for a mortgage?
Most UK lenders require at least 5-10% deposit. A larger deposit (15-20%) usually gets you better interest rates. First-time buyer schemes may allow 5% deposits with government support.
What is LTV and why does it matter?
Loan-to-Value (LTV) is your mortgage amount divided by property price. Lower LTV (bigger deposit) means less risk for lenders, resulting in lower interest rates. 60-75% LTV gets the best rates.
Repayment vs Interest-only: What's the difference?
Repayment mortgages pay off both capital and interest - you'll own the home at term end. Interest-only mortgages only pay interest - you need a separate repayment plan for the capital.
What interest rate should I use?
Check current mortgage rates (typically 4-6% in 2025). Use the rate you've been offered, or add 1-2% to base rate for estimates. Fixed rates are stable, variable rates can change.
Does this include fees and insurance?
No, this calculator shows basic mortgage payments only. You'll also need to budget for arrangement fees, valuation fees, legal costs, and buildings insurance.
How accurate is this calculator?
This provides estimates based on standard UK mortgage calculations. Actual offers depend on credit checks, lender criteria, and product-specific terms. Always get a formal mortgage illustration.
