Your deposit and total property cost
A £550,000 mortgage with a 10% deposit means you're buying a property worth £605,000. Your deposit of £55,000 gives you a loan-to-value (LTV) ratio of 90%. A larger deposit — say 15% (£90,750) or 20% (£121,000) — would reduce your monthly payments and may qualify you for a lower interest rate. Lenders typically offer their best rates at 60% LTV or below.
