At 5.10% over 25 years, the principal-and-interest payment on a £730,000 mortgage is about £4,310.15 per month. UK rates are typically fixed for 2 or 5 years and then move to the lender's variable rate, over a term around 25 years.
No — this is principal and interest only. Council tax and buildings insurance are paid separately on top. UK mortgages don't charge separate mortgage insurance — lenders price risk into the rate, so smaller deposits mean higher rates.
Over the full 25-year term at 5.10%, total interest on a £730,000 mortgage is roughly £563,045. Overpaying reduces this substantially.
