Accord Buy To Let is giving landlords who remortgage a £500 cashback on selected loans.
Landlords can choose from eight remortgage deals from the intermediary-only lender, which is part of Yorkshire Building Society.
The deals already offer free standard valuation and free legal assistance.
Chris Maggs, commercial manager at Accord, said: "New Year is synonymous with fresh starts, and it’s a time when people look to get their finances in order.
"It’s likely that the buy-to-let market will be predominately focused on remortgage lending during 2018.
"We hope by adding cashback to some of our popular mortgages, that already include additional features, it will help landlords to manage the upfront costs of remortgaging a property."
Highlights of Accord's range include a 2.44 per cent five-year fix at 60 per cent loan-to-value, a 2.49 per cent three-year fix at 65 per cent LTV, or 2.24 per cent two-year fix for landlords with a 25 per cent deposit.
Each mortgage has a £950 product fee, free standard valuation and free legal fees plus the new £500 cashback feature.
