The discounted tracker runs at 0.05 per cent below the Bank of England base rate for two years, while another will track the base rate at 0.20 per cent above it for the life of the mortgage.
Two buy-to-let products have also been launched, one on a fixed rate of 5.14 per cent until January 2010 and the other tracking the base rate at 0.34 per cent above it for the life of the mortgage - a rate of 6.09 per cent when looking at current rates of interest.
Brian Morton, sales and marketing director at Dunfermline Building Society said: “Thanks to our mutual status we are able to use our profits for the benefit of our members and this latest announcement underlines what Building Societies are all about, getting people into the housing market."
The recent professional and graduate mortgages as well as the 10 year fixed rate deals have been very popular with the market and these new products are expected to receive an equally warm welcome.
