Free standard valuations and either free legals or £250 cashback will also be applied to more of its existing loans.
The Mortgage Works managing director Paul Wootton, said: “TMW is looking to offer a wider range of options for landlords, balancing those looking for lower rates but with a higher fee, with other products offering ways to minimise upfront costs with free valuations, and either free standard legals or a £250 cashback.
“This is designed to further support landlords looking to plan and balance their costs and maintain a positive cashflow.”
