The lender is introducing a two-year fixed rate buy-to-let mortgage to its core range, which is available up to 60% LTV at 5.39% with a £999 fee.

It is also launching a fee-free two-year tracker purchase mortgage within its corporate range, which is available up to 60% LTV at a rate of 2.95%.

Furthermore, NatWest has reduced rates on a number of its core range purchase and remortgage products, including its 18-month tracker at 75% LTV, which has been cut from 3.55% to 3.25%.

The lender has also lowered its two-year fix at 75% LTV from 3.94% to 3.65%.

And in its corporate range, NatWest has reduced its two-year fix at 60% LTV from 3.55% to 3.25%, as well as lowering its five-year fix from 4.79% to 4.49%, but the fee on this product has increased from £699 to £999.

Mark Bullard, head of sales at NatWest Intermediary Solutions, says: “The buy-to-let market continues to offer intermediaries opportunities to grow their business, so the new buy-to-let product and lower rates on existing products should provide advisers with more choice.

“We won’t charge brokers’ clients basic legal and valuation fees for a standard remortgage on the new 60% LTV buy-to-let product that we have introduced into our core range.”
