For a select period of time, the lender is offering a two-year fixed rate at 3.40% and a five-year fix at 3.74% for landlords borrowing up to 75% loan-to-value (LTV) on SSC units.
There is also a two-year fixed rate at 3.60% at 75% LTV on houses in multiple occupation (HMO) and multi-unit blocks (MUBs).
The new deals come with up to £500 cashback and free valuation.
All of the limited edition products are available for purchase and remortgage.
John Heron, managing director of mortgages at Paragon (pictured), said: “Our new limited edition buy-to-let range brings added choice and flexibility for portfolio landlords looking to refinance or expand.
“The addition of cashback provides an extra boost, helping landlords fund the up-front costs associated with arranging finance and enhancing value for this important segment of the market.”
