I was served a CDC declaration

[Nathan Williams]

This is in Indianapolis.  This tenant has been current on their payments up until their September 1st rent and sent a CDC declaration.  I been giving them a "temporary" 15% discount and have forgave any late fees on their rent since this pandemic began as a way to preempt any excuses of not being able to pay rent.  I have offered a free lease termination with full deposit return and they were adamant about not moving out.  

What suggestions would you have on how to proceed?

I was going to write up a letter basically telling them that I am now suspending the discount and late fee forgiveness starting next month and reminding them that this eviction moratorium will not erase their unpaid rent and fees so its in their best interest to keep paying and not fall behind.
