Godiva Mortgages, part of Coventry Building Society, has cut its two-year buy-to-let tracker by 0.5% to Bank of England base rate plus 3.35%.
The product is available at up to 60% LTV and comes with a £1,050 fee.
It includes legal services for those remortgaging and a valuation of up to £680.
Coventry Building Society has also launched two fixed rate products which allows borrowers to overpay as much as they like with no penalty.
The rates include a two-year fixed rate deal at 3.99% at up to 65% LTV and a three-year fixed rate deal at 4.49% at up to 75% LTV.
All of Coventry’s residential products include one valuation up to £650 and a legal package for remortgage cases.
Colin Franklin, sales and marketing director at Coventry, says: “With interest rates at a historic low, many borrowers are using this opportunity to overpay on their mortgage, and in some cases become mortgage-free many years earlier than they expected.
“We’ve designed our flexx fixed range to allow them to continue doing this whilst benefiting from the security a fixed rate product offers”.
