Traditional credit scoring is statistically less inclusive for minorities, immigrants and younger people, lacking a long credit history. This happens to overlap with the majority of renters, particularly in Affordable Housing. Matrix uses real time data and produces an “ability to pay” score. Using a variety of factors, including Assets, Income and Previous Rental History, the result is more inclusive scoring that gives property managers insights into the full financial profile of a prospective tenant. Matrix removes the potential for Source of Income discrimination, taking the subsidy into consideration and automating the underwriting process. On the back end, today’s processing time for Affordable Housing is approximately 36 days. This leads to compounding losses for property managers, making public housing acceptance simply not an option for many landlords. Matrix streamlines the acceptance process and shortens it by up to 50%, helping more owners make their properties available to affordable housing and get leased up faster.
