Tenant wants to move out early - need some thoughts

[Heather S.]

Hey - please also tag me if there are other forums on this topic.  I can't find any that have a lot of actual advice.  Here's the story..  

Triplex.  2 tenants REALLY dont get along.  One is over sensitive and one is over loud.  Its been 4 months and its not subsiding.  I mean this is really a headache and not working out.  I get calls about people hitting the celing and the upstairs folks bouncing nerf balls at 9pm at night.  Sunday PM - yes during superbowl.  Downstairs tenant pounded on celing with broom, upstairs tenant went down and her dad (who doesn't live here) was there and went with her.  Downstairs tenant and upstairs get into a yelling match.  Dad says "dont talk to my daughter like that" and downstairs tenant says something to him.  Upstairs tenant got madder at downstairs tenant for talking to he dad that way and tried to punch downstairs tenant.  She missed.  She called me and said she wants to move out early and was angry.  I need to call her back today since I asked her to wait a couple days and calm down so we could connect.  The downstairs tenant said he'd like to talk about it and see if they can work it out.  

Here's my plan

1.)  I'm going to suggest they talk and see what she comes back and says 

2.) If shes still feeling anxious and upset about the monitoring and his comments about her and her kids "sounding like a herd of elephants" (and its been 4 or 5 times now) I think it makes sense to let her move out - do you guys?

3.) AND If I let her move out early - do I make any concessions to the move out clause > 60 days notice + one month rent + 50% of deposit forfeited?  Was thinking I'd keep the 60day + 50% of deposit and waive the additional fee just to get her out and get some peace.  

Would like feedback/ideas/suggestions please!!!!
