Keystone Property Finance has increased the amount of cashback offered to landlords for large loans.

Borrowers of between £150,000 and £400,000 will see a 25% increase – from £1,000 to £1,250 and borrowers of between £401,000 and £750,000 will enjoy a 33% increase – from £1,500 to £2,000.

Meanwhile, borrowers of between £750,001 and £1m will receive a 50% boost, from £2,000 to £3,000.

The lender has also split up its core, holiday let and product transfer ranges, offering a separate guide for each product suite.

Keystone managing director Elise Coole comments: “The government’s buy-to-let tax reforms in 2016 and the Prudential Regulation Authority’s decision to overhaul the underwriting rules for portfolio landlords led to a significant spike in the uptake of five-year fixed rate mortgages the following year.

“It means there will be thousands of landlords coming to the end of their deals this year who will either have to remortgage or opt for a product transfer with their current lender, if they offer one.

“By enhancing our cashback offering, we are offering landlords the ability to switch onto a competitive fixed-rate deal with another lender without the significant costs usually associated with remortgaging.”
