If you opt out of/stop reporting rent, you could lose the credit history you built while reporting your rent. Losing your rental credit history will remove a positive trade line that can impact your credit report and score.
If you complete your lease and stop reporting, your rental trade line is shown as a closed trade line in good standing.
To stop rent reporting, click the arrow by your name and choose "settings"
Then scroll down and click on "close account"
Your trade line will close by Experian if no payment is made within 90 days. Your trade line will close with Equifax and Transunion if no payment is made for 18 months.
