The research, carried out by Mortgages for Business, revealed 63% of applications made by landlords purchasing properties in quarter three were for limited company buy to lets.
This marks a significant increase from the 21% figure it was before the changes to tax relief interest were announced in July 2015.
The figures also showed remortgages made via limited companies remained stable, up marginally from 21% to 23% and are not expected to drastically increase in future.
The share of buy-to-let products available to limited companies has also risen. Limited company mortgages now represents 16% of all products, a 3% increase on the first half of the year.
But the report noted that many of the mainstream lenders still do not cater to limited company borrowers, citing Paragon to be the only one to do so.
The news comes after it was reported earlier this year that buy-to-let lending levels to limited companies were on the rise, with the first quarter of 2016 seeing higher numbers than the entire year of 2014.
David Whittaker, managing director of Mortgages for Business, said: “Many lenders with products for both personal borrowers and limited companies, offer the same rates to both. At the moment, some of these lenders accept only SPV limited companies, including Foundation Home Loans and Paragon.
“Some of the more specialist lenders, and I’m thinking primarily of Aldermore Bank, InterBay Commercial, Shawbrook and our own lending band Keystone Property Finance, also offer the same rates to trading limited companies.”
