The lender said it made the change because people are working older.
Coventry Building Society has increased its maximum age limit for buy-to-let investors at the end of term from 75 to 85.
Kevin Purvey, director of intermediaries, said: “Today’s mortgage market has to adapt to the changing needs of borrowers.
“With more people working later in life, buy-to-let investors may want to keep their investment property to supplement their income, or to help save for the future.
“We have therefore reviewed our lending policies to adapt to these changes, while of course remaining committed to lending responsibly.”
