The Nottingham Building Society has cut 75% loan-to-value buy-to-lets, which now start at 1.55%.
The range is aimed at first-time landlords, investors looking to expand portfolios and remortgagors.
The 1.55% mortgage is a 2-year fix with £999 in fees, including £299 upfront, which was cut from 1.79%.
There is also a 5-year fix at 1.78% with £1,999 in fees, as well as a 5-year fix at 2.00% with £99 in fees.
Finally there is a 2-year discount currently at 1.65% with a £99 fee.
Nikki Warren-Dean, head of intermediary sales at the Nottingham, said: “After recently revamping our residential range we decided to take a close look at our landlord offering.
“We recognise that one size doesn’t always fit all when it comes to the right mortgage option, so are pleased to be able to announce a group of reduced rate products that we are confident offer choice and flexibility.”
All products include a free basic valuation and free standard legal fees for remortgages.
