The lender has reduced its five-year fixed-rate deal to 3.60%, with the interest cover ratio (ICR) calculation at a pay rate of 3.60%.
At the same time, product fees for all buy-to-let mortgages on standard property and houses in multiple occupation (HMO) cases have been reduced to 1%.
Valuation fees have been reduced to £100 for all standard property cases.
Ian Boden, sales director at LendInvest, (pictured) said: “One year on from the launch of our buy-to-let product we are proud of the offering that we have worked on continuously throughout the year.
“As the business continues to enjoy the support of more lending capital, we are confident that the rates we’re now able to offer across our products mean we hold a very competitive position in the market.”
