The total number of live mortgage product listed on Mortgage Brain’s sourcing system rose by 15% in September, from 2,505 to 2,868.
Trackers witnessed the biggest increase during the last month, climbing by 32% to 666 products.
Fixed-rate deals rose by 14% to 1,804, while variable rate products dropped for the first time in four months by 4% to 398.
The number of mainstream lender products with a LTV of 70% or more increased by 8% last month.
Mainstream buy-to-let products fared extremely well with an increase in product numbers of 20%.
The 258 sub-prime products account for less than 1% of all products available.
Mark Lofthouse, chief executive of Mortgage Brain, says: “Overall the data from this month’s analysis is encouraging.
“Total mortgage products are at their highest for five months, the number of trackers and buy-to-let products increased significantly and the higher level LTV products also increased.
“But the appetite for offering adverse products is exceptionally limited.
“As we’ve always said, there’s still a long way to go but it’s encouraging to report positive figures as we start to head for the end of an extremely turbulent year.”
