Twenty7tec has updated its Source software to make its affordability tool more accurate for borrowers with complex circumstances.

Advisers will now be able to include more detailed information about their clients, including those with self-employed or contractor income.

The tech firm says this will enable brokers to retrieve more accurate information on the maximum loan size available from different lenders.

Twenty7Tec director Nathan Reillysays: “We’ve been working on this update for some time, as we appreciate that affordability has become an increasingly complex matter and one that has intensified over the last 12-18 months.

“In turn, we feel technology has a part to play in helping the market respond to this challenge by providing solutions that ensure a greater degree of efficiency and accuracy.

“We’re naturally pleased to be rolling this added functionality out to our users at no extra cost and we’re also committed to exploring how we can make further improvements.”
