5.48 per cent for all buy-to-let borrowers

It means Buy-to-Let borrowers can choose either "three-year" Discount, "three-year" and "five-year" Fixed Rate and "three-year" and Lifetime Tracker mortgage terms at the same rate.

The "three-year" fixed, discount and tracker mortgages end on May 31 2008 and the tracker (which is 0.73% above BBR) comes with a £250 cashback incentive for remortgages.

The "five-year" fixed rate ends on May 31 2010 and the lifetime tracker (0.73% above BBR) also comes with £250 cashback for remortgages.

The application fee for all these loans is £495 and all are available for a maximum of 10 properties (£500,000 max per property).

All the above mortgages are available through Derbyshire Intermediary Support.

Additional "three-year" fixed rate and discount BTL mortgages, both at the rate of 5.48% until May 31 2008, will also be launched on April 11 2005. The loans have a maximum exposure of £1.5m over three properties (£500,000 per property max) and are available at any of The Derbyshire's 52 branches, or by calling Derbyshire Direct on 0800 0852020.

Tony Capon, Head of Intermediary Support and Development at The Derbyshire, said: "This new range means Buy-to-Let investors don't have to choose their mortgage on the rate alone. They can select a mortgage with the terms they most prefer instead.

"So, whether you are looking for the peace of mind and protection that a fixed rate deal provides against future rate rises or a variable rate loan which will see your payments come down when the Bank Base Rate falls, The Derbyshire can offer a Buy-to-Let mortgage which suits you, with the initial rate of 5.48%.

"We are confident that the Buy-to-Let sector will continue to grow this year and the market has become an integral part of our product portfolio. These significant enhancements to our Buy-to-Let mortgage range mean even more borrowers will be able to reap the rewards of investing in this market."
