The change brings remortgage offers from the specialist buy-to-let arm of the Nationwide Building Society in line with the lender’s purchase and let-to-buy applications.
Offers for further advances currently remain valid for three months but will be extended to six months at a later date TMW said.
TMW said the changes will support landlords looking to complete a remortgage and onward purchase at the same time.
Paul Wootton, TMW’s director of specialist lending, said: “We listen to landlords and their challenges in growing portfolios and the extension of TMW’s remortgage offer period acknowledges one of the many pressures that a landlord can face.
“This change in policy, along with recent improvements to our product offering, further illustrates TMW’s continued commitment to brokers and landlords.”
The lender currently offers a five-year fixed-rate remortgage at 2.09% for up to 50% loan to value (LTV), and 2.64% for the up to 65% LTV, both with a £1,995 fee.
TMW recently removed its age limit at application for experienced landlords looking to borrow up to 65% LTV and increased the maximum LTV for buy-to-let mortgages to 80% for first time and experienced landlords.
