In 2014, a TransUnion analysis found that reporting rental payment information to credit bureaus can positively affect credit scores. As a result, TransUnion initiated a service called ResidentCredit, making it easy for property owners to report data about their tenants on a monthly basis.

As a result, some companies have started reporting rent payment information to TransUnion.
