"We have reassessed rates across our range to offer even better flexibility and support, especially to our self employed borrowers."
Newcastle has launched new buy-to-let remortgage deals available at 2.85% for two years or 3.35% for five years, both up to a maximum LTV of 75%.
Both products come with no reservation or completion fees, free standard valuation and legal fees.
The lender has also reduced rates on mortgages exclusively for self-employed borrowers who have been trading for two years and under.
Two-year fixed rate products are available from 1.90% and free valuations (on properties up to and including £500,000) and are available through all its key account distributors.
Steve Carruthers, Head of Mortgage Distribution at Newcastle Intermediaries, said: “We have reassessed rates across our range to offer even better flexibility and support, especially to our self employed borrowers.
“Additionally, our free valuation feature and low fee alternatives are ideal for those in the remortgage market.”
