With a 20% deposit at 5.10%, principal and interest are about £3,046.62 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.
A 20% deposit is £129,000, which avoids mortgage insurance where it applies. UK mortgages don't charge separate mortgage insurance — lenders price risk into the rate, so smaller deposits mean higher rates.
No — this is principal and interest. Add council tax and buildings insurance for your full monthly housing cost.
