Your deposit and total property cost
A £700,000 mortgage with a 10% deposit means you're buying a property worth £770,000. Your deposit of £70,000 gives you a loan-to-value (LTV) ratio of 90%. A larger deposit — say 15% (£115,500) or 20% (£154,000) — 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.
