The lending market is awful at the moment best residential flexi or variable rate is around 5.75% and fixed is over 6.5%. Bank on about £420 per month on £70k interest only or £520 for repayment. And dont forget, you'll need minimum 10% deposit, some lenders not even doing business at 90%. Brokers are more at risk than brickies at the moment. Desperate times Im afraid.
