Frequently Asked Questions

Common questions about UK mortgages

How much can I borrow for a mortgage?

Most UK lenders will offer between 4 to 4.5 times your annual income. Some may offer up to 5.5 times for higher earners. Your borrowing capacity also depends on your credit score, existing debts, and deposit size.

What is LTV (Loan-to-Value)?

LTV is the percentage of the property's value that you're borrowing. For example, if you're buying a £300,000 property with a £60,000 deposit, your LTV is 80%. Lower LTVs typically get better interest rates.

Fixed vs Variable rate - which is better?

Fixed rates give you certainty over your payments for a set period (usually 2-5 years). Variable rates can go up or down with the market. Fixed rates are often preferred when rates are expected to rise.

What fees are involved in getting a mortgage?

Common fees include arrangement fees (£0-£2,000), valuation fees (£150-£1,500), legal fees (£500-£1,500), and potentially early repayment charges if you switch before your deal ends.

Can I overpay my mortgage?

Most mortgages allow overpayments of up to 10% per year without penalty. Overpaying can significantly reduce your total interest and mortgage term. Check your specific mortgage terms.
