The lender is cutting interest rates on various products by between 10 and 20 basis points.
The new range contains two- and five-year fixed rate mortgages for portfolio landlords and five-year fixed rate mortgages for non-portfolio landlords.
It includes no up-front fees and £350 cashback on selected deals, with portfolio products available to individuals, limited companies and limited liability partnerships.
Portfolio offerings include a five-year fixed rate mortgage at 3.70 per cent for landlords with single self-contained units (SSCs) and one at 3.75 per cent for landlords with houses in multiple occupation (HMOs) or multi-unit blocks (MUBs).
Paragon director of mortgages John Heron (pictured) said: “Interest rates on new mortgage products have rarely been as competitive across the market as they are today.
“By cutting up-front costs and giving landlords flexibility to manage other expenses using cashback, we’re demonstrating our commitment to enabling the widest possible access for customers.”
