The "three-year" fixed has a rate of 5.38% until March 31 2008, while the "five-year" fixed has a rate of 5.48% until March 31 2010.

Two Buy to Let Trackers are also available – the "three-year" product will be 0.70% above the Bank of England Base Rate until March 31 2008, before reverting to SVR, while the Lifetime Tracker will track the BBR at 0.84% above for the term of the mortgage.

The "three-year" discount features a rate of 5.48% (1.27% below The Derbyshire's current SVR of 6.75%) until March 31 2008, with an increased maximum exposure of £1.5m over three properties (£500,000 per property max).
Procuration fees for selected intermediaries have also been increased on these Buy to Let deals. All the above mortgages are available through Derbyshire Intermediary Support.
An additional "three-year" Fixed Rate Buy to Let Mortgage, with interest fixed at 5.38% until March 31, with a maximum exposure of £1.5m over three properties (£500,000 per property max) is also available at any of the Society's 52 branches, or by calling Derbyshire Direct on 0800 0852020.
Tony Capon, Head of Intermediary Support and Development at The Derbyshire, said: "Figures show that private landlords made an average return of 31% on their investments in 2004 and with house prices still outside the reach of many first time buyers now is a good time to consider further investment in buy to let.
"These significant enhancements to our Buy to Let mortgage range mean even more borrowers can reap the rewards of investing in this market."
