Is it ever a good idea to return pre-paid last month's rent?

[Karli F.]

Hey guys, I'm in Minnesota and my renters did not meet the credit score requirement so they agreed to pre-pay the last month's rent as assurance. They are coming up on a year of timely rent and have been great tenants and with COVID and everything, I have been thinking about refunding the last month's rent. I'm looking for recommendations or advice on whether to do so or not. Thanks in advance!
