Inherited Tenant's deposit. BAD TENANTS

[Bryan Stell]

Hi Everyone,

This is a new situation for me. I bought a 5plex in a nice area, I also live in one of the units. One of my inherited tenants on the third floor is moving out and buying their own home in April. Their lease ends in May, but thats ok. I want them out.

They supposedly, via the previous sellers flushed kitty litter down the drains requiring plumbing to be redone at a $5000 expense before I purchased the property. I inherited all of their security deposit. $850.00. Should I be credited with this despite the previous sellers expense? Assuming they, their 3 cats, 1 large dog, and bunny all move out and keep the place in good condition. (only 2 cats were allowed on their original lease.  I am glad they are leaving, but just don't know what I can legally do with their security deposit.

-PS. I live in Pennsylvania.

Thanks!

Bryan
