The Mortgage Works has reduced rates by up to 50 basis points and says it is now offering its lowest-ever rates.
The Nationwide buy-to-let subsidiary has fixes starting from 2.19 per cent and trackers starting at 1.94 per cent.
Further, a fee-free 65 per cent LTV two-year fix has been launched at 2.99 per cent.
The lender has also introduced a £1,995 fee option for three- and five-year fixed rates at 65 and 75 per cent LTV.
Rates start at 2.69 per cent for the three-year fixes and 3.29 per cent for the five-year fixes.
TMW head of specialist mortgages Paul Wootton says: “This new range of competitive buy-to-let fixed-rate and tracker mortgages provides landlords with TMW’s best-ever rates and continues to demonstrate our commitment to our customers and intermediaries.
“With a likely Bank base rate rise on the horizon, TMW’s competitive range of fixed-rate products offers longer-term payment security for landlords, particularly for those with larger deposits looking to maximise their cashflow.”
