I have a resident in an apartment that has a mystery leak. I will be giving her a per diem for each day she is out of her apartment. She has filed an insurance claim through her renter's insurance so luckily they are paying her hotel and replacement costs of her personal property. Unfortunately insurance is dragging their feet so each day the leak gets worse and worse so it will be 6-7 days from time leak occurred until I can get a plumber in there.

Consider a Renters Insurance policy instead of a rent credit. It would protect them going forward (and you) without them fully getting compensation for something not under your control.

Haha thanks I needed the encouragement!

That’s not a thing. If you fixed that quickly, you’re a superstar

This situation is covered in our lease.

What is the price or cost of satisfaction ? If you get a lease renewal for two years, is one month credit a good investment ?

There is an art to negotiation. What is valuable important to other party. If they are leaving anyway, sure, no concession. If you can leverage the credit and get an extension, is that valuable to you.
