This comes as the PRA guidelines for portfolio landlords came into effect at the start of this week.
BEP Systems has launched a system enabling lenders to stress test buy-to-let portfolios automatically.
The 'Portfolio Assessor' is a new module on BEP's Apprivo2 system which was designed to save time and improve accuracy within the buy-to-let portfolio process.
This comes as the PRA guidelines for portfolio landlords came into effect at the start of this week.
Chris Little, managing director of BEP Systems, said: “This Apprivo2 module, designed for lenders, is completely PRA compliant.
"Extensive research has been carried out to ensure that it is exactly what lenders need to comply with the new PRA rules as quickly and efficiently as possible."
