Experian Credit reports are consumer-initiated reports and are only valid/available to view for 30 days from when the report is first generated. 

From Experian:  

To protect your privacy, we keep copies of your credit report and score for 30 days only. If you need to keep a copy of your credit report for longer than 30 days, then you should print out your report. If you do print your report, you should be sure to store it in a safe place.

Rent Application works with a variety of report providers. If you would like to utilize Transunion credit reports, please reach out to our support team and let them know you'd like to make the switch! We'll ask a few questions about your rental business and then get you started.
