Tenant damage to appliances and pool deck

[Connie Murphy]

this is my first rental (my personal home that I'm renting) so the house is much nicer than what a typical rental would be.  That said, I am getting a premium on my rent ($1.90/sqft).  Anyway, found out my tenants had a dog AND a cat and asked them to leave after only 4 months.  The house was dirty and they weren't maintaining anything.   So I suggested I let them out of the lease and give them a couple weeks to leave.  They did.  Now they want their deposit back.  I went over there today and took photos (have photos of the house time stamped right before they took possession).  The $2000 SS Fridge has a scratch and some weird stuff on it that won't come off.  Same thing with the dishwasher ($1000 new).  Everything in this house is high end.  One screen broken and burn marks on my pool deck in 4 places, I suspect fireworks.    The only thing I can actually fix is the screen.  How much should I charge for deterioration of the appliances and the damage to my pool deck?  Thank you in advance for your advice!
