The new range will see TMW offer limited company mortgages with free standard valuation and legal fees for purchasers for the first time.
As part of the free legals incentive, TMW will appoint the conveyancer and cover both the professional fee and the standard disbursements.
The new products are a 2-year fix and a 5-year fix, both with a rate of 3.39% and available up to 75% loan-to-value (LTV), with a £1,995 fee.
The lender has also made a series of rate reductions across selected 5-year fixes by up to 0.50%.
Buy-to-let remortgage 5-year fixed rates up to 65% LTV have been cut by up to 0.30% with rates starting from 1.59% with a 2% fee, including free valuation and free legals.
Buy-to-let remortgage 5-year fixed rates up to 75% LTV have been reduced by up to 0.40% with rates starting from 1.79% with a 2% fee, including free valuation and free legals.
And limited company 5-year fixed rates up to 75% LTV have been cut by up to 0.50% with rates starting from 3.09% with £1,995 fee, including a free valuation.
Daniel Clinton, head of The Mortgage Works, said: “There are a number of costs to consider when investing in a buy-to-let property, particularly for incorporated landlords where conveyancing fees can be higher. Our new purchase products with free standard legal and valuation fees aim to help minimise upfront costs.
“At the same time, we’re also reducing selected rates across our range to maintain a competitive position and ensure we continue to offer landlords a wide range of options.”
