Tipton and Coseley Building Society saw a 42% rise in mortgage completions in 2016.
From January to September the society achieved £54m of completions, up from £38m last year.
It also saw a 40% rise in mortgage applications from £53m last year to £74m.
Richard Newton (pictured), the Tipton’s chief executive, said: “We’ve had a great year for applications and completions which is a result of us increasing the number of mortgage products we now offer combined with our sensible approach to lending.
“With a commitment to continually reviewing our product range, I have confidence in the next quarterly figures.”
