At 5.10% over 25 years, the principal-and-interest payment on a £2,700,000 mortgage is about £15,941.64 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.
