Black Country-based Crystal Mortgages says it has enjoyed a strong third quarter and has now issued terms of £460 million so far this year.
It said this had put it on course to surpass last year's record figure of £479 million for the whole of 2013.
Between July to September the business issued terms on £142.2 million worth of applications, with completions across the 300-plus product portfolio up by 168 per cent against the same period last year.
One of its key deals during the quarter was a short-term loan for an overseas company purchasing a student investment block in Leicester for £3 million.
Managing director Joe Breeden said: "The fact we could break the half-a-billion mark for terms issued for the first time in the company's trading history is driving everyone in the business to surpass their targets.
"The large increase in figures across the board has been achieved while enquiry numbers remain broadly in line with 2013, ultimately meaning that lender appetite and product availability, from challenger banks in particular, has amplified which in turn has boosted conversion.
"We are in a very privileged position to access these funds and offer products which may herewith to be otherwise unavailable."
